Bipolar disorder: what the research says

How often do mood disorders and PMS or PMDD occur together?

Very often. Between 42% and 49% of women have both PMS or PMDD and a mood disorder at the same time, depending on which condition was diagnosed first.

Are PMS symptoms linked to genetic factors for psychiatric disorders?

Yes. Women with PMS were more likely to have genetic factors for depression, bipolar disorder, ADHD, schizophrenia, and autism spectrum disorder. This was a large, well-designed study, so we can be confident in these findings.

Is PMDD a valid medical diagnosis?

Yes. PMDD is recognized by the World Health Organization and American Psychiatric Association as a distinct medical diagnosis. Evidence suggests it has real neurobiological basis, though more biological research is still needed to fully understand it.

Does PMDD increase the risk of depression or bipolar disorder later?

Yes. Women with PMDD were 2.58 times more likely to develop depression and 2.50 times more likely to develop bipolar disorder compared to women without PMDD. These conditions also developed earlier in women with PMDD.

Do mental health disorders get worse during the menstrual cycle?

Yes, several mental health disorders like depression, panic attacks, eating disorders and borderline personality disorder clearly worsen around menstruation. The evidence is less clear for anxiety or bipolar disorder.

Do women with both bipolar disorder and PMS or PMDD need different treatment?

Yes. Women with both conditions have more severe symptoms, more frequent relapses, and worse responses to treatment. They need special care that tracks their menstrual cycle.

Are PMDD and ADHD linked in women with bipolar disorder?

In women with bipolar disorder, 44.2% have PMDD, and those with PMDD also have higher ADHD symptom scores. Genetic risk for ADHD was linked to both PMDD severity and ADHD symptoms.

How often do people have both PMDD and bipolar disorder together, and how do they affect each other?

PMDD and bipolar disorder frequently occur together, making mood episodes more frequent and severe. The connection appears to involve hormonal changes in estrogen and progesterone, though how well treatments work remains unclear.

Do anxiety and depression get worse before your period if you already have a mental health condition?

Yes. If you have depression, bipolar disorder, or other mental health conditions, symptoms often worsen before your period due to hormone changes. This can affect how well treatments work.

What is healthcare like for women with PMDD in Australia?

Most women see many doctors before getting diagnosed, more than half experience medical gaslighting and misdiagnosis, and only 19% receive the proper diagnostic tests. Getting a correct diagnosis helps women feel less confused about themselves.

What is the true rate of PMDD, and does it worsen mental health conditions?

The true rate of PMDD when properly diagnosed is 3.2%. Depression, bipolar disorder, and schizophrenia can all worsen during certain times of the menstrual cycle, and SSRIs and hormonal therapies are proven treatments.

Does a history of mood problems with your period predict depression during menopause?

Yes, women with a history of mood changes before their period or depression after childbirth were more likely to have depression symptoms during menopause.

What are the main trends in research about premenstrual disorders and related conditions?

Research on premenstrual disorders has grown steadily from 1999 to 2023. Most research comes from North America. Scientists are increasingly studying connections between PMDD and bipolar disorder.

Do women with bipolar disorder who had PMS or postpartum depression have worse mood problems during menopause?

Yes. Women with bipolar disorder who had premenstrual symptoms are 6.189 times more likely to have mood episodes during menopause, and those with postpartum depression are 2.635 times more likely to have depression during menopause.

Does hormonal contraception affect PMDD?

Yes, hormonal contraception can affect PMDD, but the effects vary by person and medication. We can't be certain which contraception works best for each woman because more research is needed.

Do women with both bipolar disorder and PMDD have worse biological rhythm disruptions?

Yes, women with both bipolar disorder and PMDD experienced greater disruptions in biological rhythms across both the follicular and luteal phases of the menstrual cycle, especially in sleep and activity patterns.

What happens when someone has both bipolar disorder and PMDD?

Women with both conditions experience more severe bipolar disorder with more mood episodes and more depression. Treatment is challenging because standard PMDD medication can trigger mania in people with bipolar disorder.

Is premenstrual dysphoric disorder linked to suicide risk in women with mood disorders?

Women with premenstrual dysphoric disorder who have depression or bipolar disorder are 3.46 times more likely to have attempted suicide. However, this study only included women who already have mood disorders.

Do psychotic symptoms get worse during the menstrual period?

Yes. Women with psychotic disorders are 1.48 times more likely to need psychiatric admission during the perimenstrual phase. Some studies also found symptom worsening during this time.

Do lithium and valproate levels change during the menstrual cycle?

In women with bipolar disorder, lithium levels decreased during the luteal phase (before the period) despite stable doses, linked to worsening mood symptoms. In healthy women, lithium levels were not affected by the menstrual cycle.

Are certain personality or mood traits more common in women with PMDD?

Yes. A cyclothymic temperament (characterized by mood swings) is much more common in women with PMDD, while a stable temperament is protective. Anger and sensitivity are also more common.

Does lamotrigine reduce menstrual cycle-related mood changes in women with bipolar disorder?

Women with treated bipolar disorder showed greater mood and sleep changes across the menstrual cycle compared to healthy women. Women taking lamotrigine had less mood fluctuation and were more similar to healthy women than those not taking lamotrigine.

Does the menstrual cycle affect mood episodes in women with bipolar disorder?

Yes, for many women. Many women with bipolar disorder experience changes in depressive, manic or hypomanic episodes linked to their menstrual cycle, though this varies widely between women.

What antidepressant should doctors use to treat depression and premenstrual dysphoric disorder?

According to expert consensus, a single antidepressant, usually an SSRI or SNRI, is recommended as first-line treatment for most types of depression, including premenstrual dysphoric disorder.

Can estrogen hormones treat depression linked to the menstrual cycle?

Yes, transdermal estrogen can treat depression linked to the menstrual cycle, pregnancy, and menopause by suppressing cyclical hormone changes. The challenge is balancing multiple hormones and managing progestogen side effects.

Are seasonal mood changes and premenstrual symptoms both common in women with bipolar disorder?

Yes, particularly in bipolar II disorder. Women with bipolar disorder experience both seasonal and premenstrual mood changes, and these two cycles appear to be related.

Does premenstrual symptom worsening change how bipolar disorder develops over time?

Yes. Women with bipolar disorder who reported premenstrual symptom worsening had more mood episodes and relapsed sooner, though other patterns in their illness may partly explain this.

Do women with bipolar disorder who have premenstrual mood changes do worse than those without?

Yes. Among women with bipolar disorder, those with premenstrual mood changes had significantly more severe symptoms, relapsed faster, and had a worse course than those without premenstrual changes.

How common is PMDD in women with bipolar disorder?

About 27% of women with bipolar disorder have a lifetime history of PMDD. When PMDD occurs with bipolar disorder, it is linked to more severe bipolar subtypes and other mental health conditions like postpartum depression and obsessive-compulsive disorder.

Does light exposure affect menstrual cycles through melatonin?

Yes, there is evidence that light exposure affects menstrual cycles and symptoms through melatonin secretion. Women with bipolar disorder or polycystic ovary syndrome may be especially vulnerable.

Are hormone-related chemicals different in women with mood disorders during the menstrual cycle?

Women with bipolar disorder and major depression had higher levels of progesterone and a related chemical (3alpha,5alpha-THPROG) during the luteal phase compared to healthy women. This difference was present whether or not they were taking medication.

Do women with bipolar disorder on mood-stabilizing medication experience premenstrual symptom worsening?

No, women with bipolar disorder on mood-stabilizing treatment (lithium or valproate) experienced significantly less premenstrual symptom worsening than healthy women, suggesting the medication may protect against it.

Does bipolar disorder affect women differently than men?

Yes. Bipolar disorder often starts later in women, who experience more depressive episodes and rapid mood cycling. The postpartum period is high-risk for onset or recurrence.

Do women with PMS have lower levels of beta-endorphin?

Yes. Women with PMS had a significantly greater drop in beta-endorphin levels compared to women without PMS. The other hormones and transmitters tested showed no clear differences.

What PMS symptoms do women experience even when not seeking treatment?

Most women have some premenstrual symptoms. The most common are depressive symptoms (65%), physical discomfort (61.7%), and fluid retention (53.4%). Only 20.3% had no negative symptoms.

What's the best way to measure premenstrual tension using mood diaries?

Six of seven tested methods gave similar results. Methods using bipolar mood scales (with both positive and negative options) and based on known symptom patterns worked best, though some complex cases showed discrepancies of 9-23%.

Are there different types of premenstrual symptoms?

Yes. Research found three main patterns of premenstrual changes: hostile-depressive, atypical depressive, and anxious, as well as two less common patterns.

Can one questionnaire help doctors tell the difference between PMS, PMDD, and other mood disorders?

Researchers created a new questionnaire called COMPASS designed to help doctors distinguish PMS, PMDD, and perimenopause from conditions like depression, personality disorders, and trauma disorders that cause similar symptoms.

Is premenstrual dysphoric disorder now recognized in the international diagnosis system?

Yes. ICD-11 now officially recognizes premenstrual dysphoric disorder as a depressive disorder, with seven new specifiers to describe depressive disorders. Specific guidance for children and adolescents still needs more research.

Do suicidal thoughts change across the menstrual cycle?

The study found no clear pattern of suicidal thoughts changing with cycle phases. However, feelings like depression, anger, and irritability (which do vary across the cycle) were linked to suicidal thoughts.

Can hormonal therapy treat psychotic symptoms tied to the menstrual cycle?

This case describes a 26-year-old woman whose psychotic symptoms appeared with her menstrual cycle. Antipsychotic medication initially helped, but low-dose hormonal birth control led to lasting improvement.

Among women with bipolar I disorder, who is more likely to also have PMDD?

About one-third (36.5%) of women with bipolar I disorder have PMDD. Those at higher risk have seasonal mood patterns, a history of suicide attempts, and a family history of mental illness.

Does the menstrual cycle affect obsessive-compulsive disorder symptoms?

Yes, all 12 studies found that OCD symptoms worsened during the premenstrual phase. However, most research relied on self-reports rather than objective measurements.

Could early stress or past trauma make PMDD symptoms worse later in the cycle?

This research offers a possible explanation for why PMDD symptoms vary so much, and why related conditions can worsen before a period. It is only a theory, not tested on patients, so we don't yet know if it is true.

Can birth control medication help menstrual cycle-related psychosis?

Yes, in one case. A woman with severe monthly psychotic episodes linked to menstruation had sustained improvement over four months after adding a combined oral contraceptive.

What is dysphoria and how does it feel in premenstrual disorder?

Dysphoria is a mood state where the world feels oppressive and pressing. In premenstrual disorder, it shows as irritability, mood instability, physical restlessness, and loss of control. Unlike depression, it typically stops when menstruation begins.

How does the menstrual cycle affect psychiatric symptoms like depression and anxiety?

Many women experience worsening psychiatric symptoms during the premenstrual and menstrual phases due to hormonal changes in estrogen and progesterone. Treatment should monitor symptoms across the menstrual cycle and may include lifestyle changes, therapy, antidepressants, or hormonal therapies.

Can lithium help treat PMDD when other medications are not an option?

Yes, based on one case. A woman with PMDD and a family history of bipolar disorder responded well to lithium treatment.

Can PMDD cause psychosis that returns with each menstrual cycle?

Yes. A woman experienced psychotic symptoms starting 5 days before her period and ending when her period began, and this pattern repeated every month for 5 years. Treatment with medications reduced the severity but did not completely stop the symptoms.

Are PMS or PMDD linked to different features of bipolar disorder in women?

Yes. Women with bipolar disorder and PMS or PMDD became ill at younger ages, had worse depression symptoms with more anxiety and thinking problems, and were more likely to have OCD or family history of mental illness. This is observational, so we cannot prove cause and effect.

What is menstrual psychosis?

Menstrual psychosis is a rare condition causing severe psychiatric symptoms that repeat with the menstrual cycle. This case shows that psychiatry and gynecology doctors must work together to diagnose and treat it properly.

Does a new questionnaire reliably measure both period and mood symptoms together?

Yes, the MAC-PMSS correlates well with standard mood and symptom measures in women with mood disorders, though the study was small.

Can women get psychosis linked to their menstrual cycle?

Yes, menstrual psychosis exists but is extremely rare, with only 30 cases reported worldwide. Estrogen's effect on the brain may play a role.

What factors make PMS mood swings worse?

Stress, gynecological conditions like endometriosis and PCOS, and family history of bipolar disorder can worsen PMS. About two-thirds of women (67.4%) reported PMS and a quarter (25.6%) had PMDD.

Are PMDD and bipolar disorder connected?

Yes. PMDD is more common in women with bipolar disorder than in the general population, and bipolar disorder is more common in women with PMDD. Between 10% and 15% of women with PMDD also have bipolar disorder, while 27% to 76% of women with bipolar disorder also have PMDD.

What is cyclic menstrual psychosis in adolescents?

This case describes a 14-year-old girl with psychotic symptoms including confusion, delusional ideas and physical restlessness that occurred in a repeating cycle linked to her menstruation. The symptoms went away when her period began.

Do women with depression or bipolar disorder experience worse symptoms before or during their menstrual cycle?

About 60% of women with mood disorders report premenstrual worsening of symptoms, which predicts worse disease overall. Current PMDD treatments work less well or not at all for this problem, and more research is needed to understand what helps.

Can PMDD be mistaken for bipolar disorder?

Yes. PMDD and bipolar disorder have similar mood symptoms, which can lead to wrong diagnosis and treatment. A woman given lithium for bipolar disorder stayed sick, but recovered when she started antidepressant medication, which is the correct treatment for PMDD.

How should doctors treat PMDD in women who also have bipolar disorder?

Very few studies exist on this combination, making treatment challenging. The evidence suggests treating bipolar disorder first with mood stabilizers, then addressing PMDD symptoms separately, but this is based on treating each condition alone rather than research on both together.

How should premenstrual syndrome be diagnosed and treated?

PMS is diagnosed by tracking cyclical symptoms that appear 2-14 days before menstruation and disappear when menstruation starts. Both hormonal treatments like birth control pills and non-hormonal treatments like Vitex extract have been shown in research to be effective.

How do psychotic symptoms connected to the menstrual cycle look in different parts of the world?

In a study of 4 women in Oman with menstrual psychosis, all had psychotic and mood symptoms timed to their menstrual cycle. All had normal intelligence but had problems with thinking speed, memory, and planning skills.

How common is PMDD in young adult women and what factors increase the risk?

PMDD affected 17.6% of young adult women studied in Brazil and was more common in older women and those with lower income. The study relied on women remembering past symptoms, so the actual rate may differ.

How common is PMDD in women with psychiatric disorders?

PMDD was far more common in women with psychiatric conditions than controls, especially among those with depression. The findings suggest PMDD is closely related to mental health conditions, particularly depression and bipolar disorder.

What is the impact of having both bipolar disorder and premenstrual dysphoric disorder?

Women with both conditions experience significantly worse bipolar illness: earlier onset, more rapid cycling, more mood episodes, and higher rates of anxiety disorders and other conditions. They also experience more severe symptoms during pregnancy and while taking oral contraceptives.

Are PMS symptoms linked to mood disorders and personality?

This study found significant relationships between PMS symptoms and lifelong mania or hypomania symptoms, and between PMS and personality traits. Because it was cross-sectional, we cannot know if hormonal changes in PMS cause mood and personality changes.

Can mood symptoms like mania and psychosis change across the menstrual cycle in bipolar disorder?

In one detailed case, yes: a woman with bipolar I disorder had psychosis-like symptoms when estrogen was low and hypomania when estrogen was high, and a targeted treatment approach for this pattern worked for her.

How many young women have premenstrual syndrome?

The abstract is mostly in Polish and incomplete, so we cannot give a clear answer about prevalence from the available text.

Do women with major depression or bipolar disorder experience more premenstrual symptoms than healthy women?

Women with major depression in remission had more PMS than healthy women, with higher scores for depressive mood, anger, and other symptoms. Women with bipolar disorder in remission had similar PMS rates to healthy women.

What causes schizophrenia, mania, and depression?

This is a theoretical proposal, not based on study of actual patients. The author suggests these conditions may result from imbalances in brain chemicals and amino acids, influenced by activity levels.

How are hormones related to depression in women?

Depression in women is caused by hormonal changes at certain times: before periods, after birth, and around menopause. These can be effectively treated with medications or procedures that change hormone levels, especially transdermal estrogens.

Does tubal ligation affect periods and premenstrual symptoms?

Yes. After the surgery, premenstrual symptoms increased significantly, along with heavier periods and more pain during periods. Women under 35 were more likely to experience these changes.

Can psychotic episodes happen in a pattern linked to the menstrual cycle?

Yes. Psychotic episodes linked to menstruation may remit between cycles and become much less common after menopause.

Can mood disorder symptoms happen only during the second half of the menstrual cycle?

One woman had cycles of high mood followed by low mood that happened only during the second half of her menstrual cycle, repeating each month.

Can high testosterone levels be connected to PMDD, bipolar disorder, and certain medications?

In one woman with bipolar disorder and PMDD on quetiapine and lithium, initial testosterone was 88.5 ng/dL. When hormone levels were normalized, testosterone returned to normal. This is one case only.

Can contraceptive medications help people with both bipolar disorder and PMDD?

Three people with both conditions improved significantly. These are only three cases, so we need larger studies to be sure.

Can severe mood changes around a period be an early sign of bipolar disorder?

In one teenage girl, a psychotic episode tied to her period turned out to be the first sign of bipolar disorder. This is a single case, so it cannot tell us how common this is.

Does olanzapine help premenstrual psychosis?

One girl with recurrent premenstrual psychosis was successfully treated with olanzapine. This is one case of a very rare condition, so we need much more research.

Can the menstrual cycle trigger hypomanic episodes in bipolar disorder?

This case describes an 18-year-old woman with bipolar disorder who experienced hypomanic episodes aligned with her menstrual cycle since the start of her periods, followed by depressive episodes. This shows that mood episodes and the menstrual cycle can be connected in some people.

How can doctors tell the difference between severe PMS and bipolar disorder?

Doctors can tell the difference by looking for symptoms that clearly follow the menstrual cycle and improve during pregnancy. These patterns occur in severe PMS but not in bipolar disorder, and severe PMS doesn't respond to antidepressants or mood-stabilizing medications used for bipolar disorder.

Does being close to menstruation increase the risk of psychiatric hospital admission?

Yes. 37% of women were admitted within 5 days of their last menstrual period, which is significantly more than would be expected by chance.

What is menstrual psychosis and how is it connected to the menstrual cycle?

Menstrual psychosis is a rare illness that looks like manic depressive (bipolar) disorder but comes on in a pattern linked to the menstrual cycle. The review suggests this link involves the hypothalamus, but this is based on case evidence, not a controlled study.

Are bipolar disorder, seasonal affective disorder, and premenstrual symptoms related?

This is a review article that explores potential connections between these three cyclical mood disorders. The abstract does not present specific empirical findings or results from research.

Are women with PMDD more sensitive to how light affects sleep hormones?

The study tested whether women with PMDD respond differently to light exposure by measuring effects on melatonin, a hormone related to sleep, at different times in the menstrual cycle.

Are bipolar mood symptoms affected by the phase of the menstrual cycle?

No clear difference in bipolar symptoms across menstrual cycle phases was found overall. However, a small number of women showed mood changes during the luteal phase.

Do hormone changes during the premenstrual phase relate to mood symptoms in women with mood disorders?

In women with bipolar disorder and major depression, progesterone and allopregnanolone levels during the premenstrual phase are linked to mixed mood features and suicidal ideas, particularly in those with bipolar disorder. We cannot be certain because the study is very small.

What is dysphoria, and how is it different from other mood problems?

Dysphoria is a complex emotional state combining intense unhappiness and discontent with irritability. It is related to but distinct from other mental health conditions like depression.

Do women with depression or bipolar disorder experience premenstrual mood symptoms?

67.7% of women with major depression or bipolar disorder reported premenstrual mood symptoms, significantly more than women without mood disorders. The rates were similar between the two diagnoses.

Does the menstrual cycle affect mood disorders?

Some women with mood disorders may experience worsening symptoms during the premenstrual period. Evidence is limited and study methods are inconsistent across available research.

How does acute tryptophan depletion help us understand mood disorders?

Acute tryptophan depletion is a research method that temporarily lowers serotonin levels in the brain to study its role in depression, anxiety, sleep problems, and psychiatric conditions.

Can menstruation trigger severe mental illness like psychosis?

Yes. Medical case reports show that menstruation can trigger psychotic episodes in some women, particularly around the time of the period or repeatedly in cycles tied to the menstrual cycle.

Do women with bipolar disorder experience mood changes across their menstrual cycle?

Yes. Most women with bipolar disorder taking medication reported significant mood changes linked to their menstrual cycle, and most also had unusually long menstrual cycles. However, the study was very small.

Can mood disorders get worse before your period?

Yes. Mood disorders can worsen before the period. This is different from PMDD and PMS but it is not well understood.

Do antidepressants work differently for women, and can they help PMDD?

This expert review suggests newer antidepressants (SSRIs) may work better than older ones in women and may help premenstrual dysphoric disorder (PMDD), including when taken only in part of the cycle, but it is an opinion piece summarising other research, not a new trial.

Does menstrual cycle phase affect mood in women with rapid cycling bipolar disorder?

No. This study found no systematic pattern between menstrual cycle phase and mood in women with rapid cycling bipolar disorder, even though some individual women showed a connection.

Do SSRI antidepressants work for PMDD?

Yes, SSRIs are the treatment of choice for PMDD because they are effective, have acceptable side effects, and are well tolerated.

What does research say about diagnosing and treating PMS and PMDD?

This review explains that careful symptom tracking and ruling out other conditions are key to diagnosing PMS, and that some promising drug treatments exist for PMDD, though it is unclear if they work as well for milder premenstrual symptoms.

Are the eating changes some women get around their period part of a wider pattern of cyclic mind-body changes?

This review suggests yes: period-related eating changes may overlap with other cyclic conditions like PMS, seasonal mood changes, bipolar disorder, and binge eating, but it is an opinion-style review, not a trial, so it cannot prove cause and effect.

Does the menstrual cycle affect compulsive hair-pulling?

Yes. Women reported premenstrual worsening of hair-pulling urges, frequency, and difficulty controlling the behavior, with improvement during menstruation. Pregnancy effects were variable.

Do psychiatric symptoms get worse during certain phases of the menstrual cycle?

Some reports suggest that psychiatric symptoms worsen during premenstrual and menstrual phases, but evidence is limited because most studies have been small and tracked women informally.

Do personality traits change with the menstrual cycle in women with PMDD?

Women with PMDD have certain personality traits like passivity and aggression that are consistent with higher depression and mood elevation compared with controls. These traits do not change between menstrual cycle phases.

Are women happy taking the birth control pill and what side effects do they experience?

Most women are happy with the pill. Periods become shorter and lighter, though some experience weight gain and breast tenderness.

What's different about women who seek treatment for premenstrual mood changes?

Women seeking treatment reported significantly more depression, anxiety, and unwanted negative thoughts than those not seeking treatment. Both groups had similar physical symptoms. The commonly used 30% improvement rule did not distinguish the two groups well.

Can extreme sleepiness around periods be linked to prolactin and a medication called metoclopramide?

In one woman, severe sleepiness tied to her menstrual periods continued even after her periods stopped with metoclopramide, and this sleepiness was linked to high prolactin levels, but this is a single case and cannot tell us how common or treatable this is in general.

Does low-dose valproate help premenstrual syndrome?

In this small trial, only 3 of 8 women with premenstrual syndrome (38%) reported good response to low-dose valproate, while 5 reported no response. The medication worked much better for mood disorders than for PMS.

Does the menstrual cycle affect depression and other mood disorders?

For some women who have existing mood disorders, the premenstrual phase can increase vulnerability to severe depression or make ongoing depression worse. The paper reviews evidence for this link.

What mood disorders affect women and how should they be treated?

Yes. Premenstrual depression is strongly linked to major depression and responds well to serotonin-boosting antidepressants. SSRIs are especially useful because they have few side effects and are safe even in overdose.

Does thyroid disease cause behavioral and emotional problems, especially in women?

This review discusses that thyroid regulation problems happen more often in women than men and are often linked to behavioral and emotional symptoms, though it does not present new research findings.

Do mood disorders affect premenstrual depression and attention across the cycle?

Only 8 of 16 women with a mood disorder history actually had premenstrual depression when tracked daily. Those who did showed worse mood premenstrually, but both groups showed the same attention patterns in both phases.

What psychiatric conditions are associated with premenstrual tension syndrome?

Depression is the main psychiatric condition. Other conditions like anxiety, psychosis, alcoholism, and bulimia may also occur. Treating the psychiatric illness does not necessarily treat the premenstrual symptoms.

What medicines work best for treating moderate to severe premenstrual syndrome?

For mild to moderate PMS, the first approach should be diet, exercise, and nutritional supplements. For severe cases, medications like danazol, estrogen implants, or progesterone at 300 mg per day can be tried, though evidence for some is still limited.

Does the menstrual cycle change how the brain processes sound?

No. The brain's processing of sound did not change between the day before menstruation and 9 days after cycle start, despite significant mood changes.

Can women with premenstrual mood changes develop serious mood disorders?

In some women with premenstrual mood changes, a serious mood disorder called manic-depressive illness may develop, but mainly in those with genetic predisposition. Doctors should watch for severe mood problems after pregnancy in women with this pattern.

Can we tell women with PMS apart from women with mood disorders based on symptoms?

Not easily. Reported PMS symptoms alone cannot reliably identify women with diagnosed PMS. Women with mood disorders reported fewer PMS-like changes than expected from previous research.

Yes. This single woman showed that her blood lithium level changed in sync with her mood swings: highest during depression, lowest during hypomania, even though she took the same dose every day.

Does lithium help with premenstrual tension?

Case reports suggested it might help, but well-designed research studies found no benefit.

Are all premenstrual depressive changes the same type?

No, premenstrual depressive changes vary by type, and some types resemble mood disorders, which may help us understand both premenstrual and mood conditions better.

Can we measure all the different types of premenstrual changes women experience?

Yes. A new measurement tool called the Premenstrual Assessment Form can measure the wide variety of mood, behavior, and physical changes women experience before their period and recognizes that PMS is not one single syndrome.

How does the menstrual cycle affect mood and sexual arousal?

The menstrual cycle affects mood in women. The strongest effects occur before the period, when some women become depressed or irritable. Physical symptoms also accompany these mood changes.

Could hormone-driven changes in brain chemicals explain premenstrual mood swings?

This 1971 review suggests that shifting levels of ovarian hormones (estrogen, progesterone, aldosterone) during the cycle may affect mood by altering brain chemicals called monoamines, but this is a theory built from combining older human and animal studies, not a new trial in women with PMS.

What symptoms do women experience with premenstrual tension?

Premenstrual tension causes many different physical and emotional symptoms ranging from mild to severe, including nervousness, irritability, depression, headaches, nausea, and bloating.
