# What changes happen to young girls before their period?

The study describes observations of young girls in the days before menstruation, though the specific findings are not fully stated in the available abstract.

 Early or limited evidence

50 young female patients examined at Cleveland City Hospital starting in 1933, plus 9 additional patients

## What they did

Starting in 1933, researchers examined 50 young female patients at Cleveland City Hospital and outpatient clinics in the period before their menstruation. An additional 9 patients were also observed.

## What they found

The abstract describes the patient population and examination period but the specific findings about what changes occur before menstruation are not completed in the provided abstract.

## What it means for you

This is an early systematic observation of premenstrual changes in adolescent girls, but the incomplete abstract prevents understanding what was actually found. The findings may have historical importance in recognizing premenstrual changes in younger people.
