# Can smartwatches detect mood changes in PMDD?

A small early-stage study suggests smartwatches may be able to track the mood changes that happen in PMDD, but much more research is needed.

 Early or limited evidence

People with PMDD (sample size not stated)

## What they did

Researchers used smartwatches to monitor mood changes in people with PMDD. They tested whether a smartwatch monitoring system would work and whether measurements from the watch matched actual mood changes.

## What they found

The smartwatch monitoring system was feasible to use. Measurements from the smartwatch appeared to be connected to mood states in people with PMDD.

## What it means for you

This is very early research testing only whether smartwatches could work for monitoring mood. It does not show whether smartwatches actually help people with PMDD feel better. The sample size and other methods are not described in the abstract.
