NORMAN E. ROSENTHAL is the world-renowned psychiatrist and bestselling author, who first described seasonal affective disorder (SAD) and pioneered the use of light therapy as treatment during his time at the National Institute of Mental Health. A prolific researcher and writer, he has written more than three- hundred scholarly articles and authored or co-authored ten popular books.

Seasonal affective disorder (SAD) is a type of depression that is related to changes in seasons. It is also known as winter depression or seasonal depression. SAD typically begins and ends at the same time each year, usually starting in the late fall or early winter and subsiding in the spring or summer.

Treatment options for SAD include light therapy, where individuals are exposed to bright artificial light that mimics natural sunlight, which can help regulate mood and improve symptoms. Other treatments may include psychotherapy, medication (such as antidepressants), and lifestyle changes such as regular exercise, getting outside during daylight hours, and practicing good sleep hygiene.
It's important to note that SAD can also occur during the summer months, although it is less common. This is known as reverse seasonal affective disorder, and it may have different symptom patterns and treatment approaches compared to winter-onset SAD.
