Mood Disorders — MCQs

Q: What is the definition of "double depression" in the context of mental health?

Depression superimposed on dysthymia. ***Depression superimposed on dysthymia*** - **Double depression** refers to the co-occurrence of a major depressive episode in an individual who already suffers from **dysthymia** (persistent depressive disorder) - This means the person experiences periods of more severe depression on top of their chronic, milder low mood - This combination results in a more severe clinical presentation and worse prognosis *Recurrent major depressive episodes without chronic low mood* - This describes **recurrent major depressive disorder**, where distinct episodes of severe depression occur without a persistent background of mild depression - It does not involve the chronic, low-grade depressive state characteristic of dysthymia *Major depressive disorder occurring alongside cognitive decline* - While depression can be associated with cognitive symptoms, this is not the standard definition of "double depression" in psychiatric diagnostic criteria - This would represent a comorbidity rather than the specific term "double depression" *Chronic low-grade depression without major depressive episodes* - This describes **dysthymia** (persistent depressive disorder), characterized by chronic, low-grade depressed mood lasting at least two years - This definition specifically excludes major depressive episodes, which is the key component that differentiates "double depression"

Q: Which of the following is least characteristic of mania?

Disorientation. ***Disorientation*** - While psychotic features can occur in severe mania, **disorientation** (confusion about time, place, or person) is not a typical or primary symptom. - It suggests a more profound cognitive disturbance or an organic cause (such as delirium), which is less characteristic of an uncomplicated manic episode. - The presence of disorientation should prompt evaluation for medical causes. *Decreased need for sleep* - **Decreased need for sleep** is a hallmark symptom of a manic episode and one of the core diagnostic criteria. - Individuals with mania feel energetic and rested despite sleeping very little (often 2-3 hours or less). - This is distinct from insomnia—patients don't feel tired or have difficulty sleeping; rather, they simply don't need much sleep. *Pressure of speech* - **Pressure of speech**, characterized by rapid, loud, and difficult-to-interrupt speech, is a core diagnostic feature of mania. - It reflects the underlying racing thoughts (flight of ideas) and increased psychomotor activity typical of manic episodes. - Speech may be tangential, circumstantial, or filled with puns, jokes, and theatrical references. *Grandiose delusions* - **Grandiose delusions** (delusions of grandeur), such as believing one has special powers, extraordinary wealth, or a special relationship with famous figures, are common psychotic features in severe mania. - These delusions are mood-congruent and consistent with the elevated mood, inflated self-esteem, and impaired judgment seen in manic episodes.
