Which subtype of depression is characterized by a lack of reactivity, worsening mood in the morning, and excessive guilt?

• A. Atypical depression
• B. Melancholic depression
• C. Chronic depression
• D. Seasonal affective disorder

Answer: (B)

Melancholic depression is distinguished by several specific features, one of which is a lack of reactivity to pleasurable stimuli. Patients with this subtype often experience a consistently low mood that does not improve regardless of positive circumstances or events in their lives, highlighting a significant difference compared to other forms of depression.

Additionally, melancholic depression is often marked by a worsening of mood in the morning, which can be particularly debilitating for individuals as they face the start of a new day. This characteristic is part of the diurnal variation commonly observed in melancholic depression, contrasting with other types where mood may fluctuate more throughout the day.

Excessive guilt is another critical symptom associated with melancholic depression. This can manifest as profound feelings of worthlessness or self-reproach, which can severely impact the individual’s functioning and overall quality of life. Together, these symptoms delineate melancholic depression from other subtypes, making it essential for diagnosis and treatment approaches tailored to its specific characteristics.
