Which depression subtype is more common at higher latitudes among young people and often involves a craving for sweets?

The correct response highlights Seasonal Affective Disorder (SAD) as the depression subtype more prevalent at higher latitudes, particularly in young people. This condition is characterized by symptoms that correlate with the changing seasons, typically worsening during the fall and winter months when daylight exposure is reduced.

Individuals experiencing SAD often report specific cravings for carbohydrates and sweets, which can be attributed to the alteration in serotonin levels that accompany the lack of sunlight. The decreased exposure to sunlight during these seasons can lead to disruptions in circadian rhythms and might exacerbate the desire for foods that can temporarily elevate mood.

In contrast, atypical depression, while it can involve increased appetite and weight gain, does not have the same seasonal pattern or geographical correlation as SAD. Psychotic depression involves more severe symptoms such as delusions or hallucinations and does not specifically relate to seasonal changes. Dysthymia is characterized by a chronic low mood lasting at least two years but also lacks the seasonal and craving components found in Seasonal Affective Disorder.
