Cohort study, 2020

Do schizophrenia symptoms change across the menstrual cycle?

Yes, schizophrenia symptoms significantly vary across different phases of the menstrual cycle. Positive symptoms improved during the progesterone phase, while negative symptoms and general psychopathology improved during the estrogen phases.

Early or limited evidence 40 female inpatients with schizophrenia at a psychiatric hospital

What they did

A cohort study of 40 female inpatients with schizophrenia at a psychiatric hospital. Researchers assessed their symptoms using the PANSS scale across three different menstrual cycle phases (premenstrual, menstrual, and postmenstrual) over a period of 15 months, tracking up to two menstrual cycles per person.

What they found

Positive symptoms improved significantly only during the progesterone phase. Negative symptoms and general psychopathology scores showed improvement during the estrogen phases of the menstrual cycle.

What it means for you

Hormone changes during the menstrual cycle may affect schizophrenia symptoms in women, suggesting that treatment may need to be adjusted for individual women. This study included only hospitalized patients, so findings may not apply to women with schizophrenia living in the community.
