• A. Starts in spring, ends in summer
• B. Starts in summer, ends in fall
• C. Starts in fall, ends in spring
• D. Starts in winter, ends in fall

Answer: (C)

Seasonal Affective Disorder (SAD) is a type of depression that is related to changes in seasons, primarily affecting individuals during the shorter days of fall and winter. It typically begins in the fall as daylight hours decrease and can continue into the winter months. Many people experience symptoms improving with the arrival of spring when days become longer and brighter.

This seasonal pattern of onset in the fall and resolution in the spring is well-established in research on SAD, highlighting the role of light exposure in mood regulation. Individuals affected by SAD may find that as spring comes, their mood improves significantly, aligning with increased daylight and warmer weather. This understanding is crucial in addressing SAD, as light therapy and other treatments can be particularly effective during the fall and winter months when symptoms are most prevalent.
