Prevalence and associated features of depression in women with Rett syndrome.

van Timmeren et al. (2016) asked caregivers about mood in adult women with Rett syndrome. They used a short yes-or-no depression screen that works for people who cannot speak. Caregivers answered for 14 women living in the United Kingdom.

Two of the 14 women screened positive for depression. That is about one in seven. The same women also showed more daytime lethargy and social withdrawal than the others. No woman had a prior depression diagnosis.

Doughty et al. (2002) surveyed carers of 91 adult women with Rett syndrome and found lower irritability and hyperactivity than in other adults with intellectual disability. van Timmeren et al. (2016) now show that quiet behavior can mask depression, not just good adjustment. The two studies together warn us that "calm" may mean "sad."

Clarkson et al. (2017) and Ward et al. (2021) proved girls with Rett can reveal inner life through eye-gaze tasks. van Timmeren et al. (2016) used caregiver report instead, but all three papers share the same goal: find what the person cannot say out loud.

Gomathi et al. (2020) reviewed 70 drugs for Rett and found none ready for clinic. Until medicine catches up, careful behavioral screening like van Timmeren et al. (2016) is our best tool.

If you work with women who have Rett syndrome, treat social withdrawal and daytime lethargy as red flags. Ask caregivers two quick mood questions and refer positives to psychiatry. Early depression care can lift quality of life without waiting for new drugs.
