Which of the following terms describes a mood disorder associated with certain seasons?

Seasonal affective disorder (SAD) is the correct answer because it specifically refers to a type of depression that occurs at a particular time of year, usually during the fall and winter months when daylight hours are shorter. Individuals with SAD often experience symptoms such as low energy, changes in sleep patterns, and feelings of hopelessness during these seasons. This mood disorder is closely linked to changes in light exposure and can often be treated with light therapy, among other interventions.

In contrast, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder are all classified as anxiety disorders and do not have a seasonal component. These conditions can occur year-round and are characterized by different symptoms unrelated to specific times of the year. Understanding the nuances of these mental health conditions helps in recognizing their distinct characteristics and ensuring appropriate treatment approaches for those affected.
