NIMH Twitter Chat on Seasonal Affective Disorder

Science Update

The National Institute of Mental Health (NIMH) and the National Center for Complementary and Integrative Health (NCCIH) are co-hosting a Twitter chat to discuss Seasonal Affective Disorder (SAD). The chat will take place Tuesday, February 20, 2018, from 1:30 p.m. to 2:30 p.m. ET.

SAD is a type of depression that comes and goes with the seasons, typically starting in the late fall and early winter and going away during the spring and summer. This chat will cover SAD signs and symptoms, risk factors, and treatments and therapies. Two experts will be available to answer questions:

  • Matthew Rudorfer, M.D., Somatic Treatments and Psychopharmacology Program Chief, NIMH Division of Services and Intervention Research
  • David Shurtleff, Ph.D., Acting Director, NCCIH

To ask questions, you must have a Twitter account. Remember to use #NIMHChats with your questions and posts. If you do not have a Twitter account, you can still observe the chat in real-time by entering #NIMHchats at An archive of the chat will be posted on NIMH’s website following the event.
