Serious Mental Health Problems in Prader-Willi Syndrome

Mental Health in PWS

Mental health and behavioral problems are a significant challenge for many individuals with Prader-Willi syndrome (PWS) and can have a significant impact on quality of life and independence for both the person with PWS and their family.  People with PWS are at a higher risk of developing depression, bipolar disorder and psychotic symptoms particularly while in their teens and young adulthood. Below, we will share how to identify changes in mental health, where you can go to get help and how to begin treatment, along with special considerations for people with PWS. 

What Should You Look For?

Look for changes in the person from their usual behaviors (their baseline):

  • Eating – less interest in food, consuming less food than usual
  • Behavior – more agitation or aggression, more talkative or more withdrawn than usual (spending more time alone, less willing to engage in activities they previously enjoyed)
  • Sleep – sleeping less, or a change in sleep pattern (up more at night or earlier in the morning, more napping)
  • Grooming – loss of interest in self-grooming (not changing clothes, brushing hair or teeth, showering)

If the above changes in usual behavior are not related to physical illness and have continued for more than 1-2 weeks, take the person with PWS for an assessment.

Where Can You Go For Help?

Start with their primary care doctor or mental health provider.

How To Begin Treatment

The Golden Rule for Medications in PWS  =  Start LOW Go SLOW

  • Identify target behaviors and track those behaviors when starting or increasing a medication to see improvement or worsening of symptoms (pick 2-3 behaviors to track or use a digital behavior app).
  • Ask your doctor how quickly the medication works so you know when you might see changes.

Special Considerations for PWS

When working to identify and treat mental health symptoms, there are several special considerations for people with PWS. 
  • People with PWS by UPD have a very high risk for psychiatric symptoms BUT people with the deletion subtype also have an elevated risk compared to the typical population.
  • People with PWS are highly stress sensitive. Even seemingly small changes in their environment (sibling moving out, change in teacher/aide/caregiver, illness in close relative) have the potential to cause psychiatric symptoms (such as hearing voices/psychosis, depression). These symptoms can usually be successfully treated with use of appropriate medication.
  • It is common for people with PWS to talk to themselves and with “imaginary friends.” If the amount of talking significantly increases and/or this “friend” starts being scary or mean, this is concerning and would warrant assessment by a health care professional and possible treatment.
  • If the person with PWS goes to the ER or is hospitalized, BE AWARE — hospital settings often do not understand food issues in PWS. Hospital staff will need A LOT of education about managing food and food security for the person with PWS in the hospital setting.
