Seasonal affective disorder (SAD): Part 1 – history, epidemiology, aetiology and diagnosis

The idea that our well-being fluctuates with the seasons has been around for literally thousands of years, but it was only in the late 1980s that Norman Rosenthal and colleagues gave a name to seasonal affective disorder or SAD.

In this module, we will look at:

• the history and evolution of SAD
• the epidemiology and aetiology of SAD
• symptoms of SAD and diagnosis.
