How does the diagnosis of persistent depressive disorder differ from major depressive disorder?
The onset of persistent depressive disorder is usually late in life
Hypomanic episodes are present in persistent depressive disorder
Persistent depressive disorder has a high-grade chronicity
Persistent depressive disorder is subjective in nature
The Correct Answer is C
Choice A reason: Persistent depressive disorder can begin at any age, including adolescence, not only late in life.
Choice B reason: Hypomanic episodes are features of bipolar disorders, not persistent depressive disorder.
Choice C reason: Persistent depressive disorder (dysthymia) is characterized by a chronic, low-grade depressive state lasting at least two years in adults, differentiating it from the episodic nature of major depressive disorder.
Choice D reason: Both persistent depressive disorder and major depressive disorder are diagnosed based on objective criteria, not solely subjective reports.

Correct Answer is C
Explanation
Choice A reason: While CBC and CMP are essential baseline labs, they are insufficient for a middle-aged patient on psychotropic medications and with chronic medical conditions, as they do not assess nutritional deficiencies or lipid status.
Choice B reason: Adding a lipid profile and thyroid panel increases the scope of monitoring but still omits critical nutritional labs like vitamin B12 and D, which are relevant for long-term mental health, bone health, and medication effects.
Choice C reason: This comprehensive lab panel covers blood counts, metabolic status, lipid profile, thyroid function, and essential vitamins. Vitamin B12 and D deficiencies are common in adults on chronic psychotropic medications and can impact mood, cognition, and overall health.
Choice D reason: Using a BMP instead of CMP provides less information about liver function, which is important for monitoring medication safety. Omitting vitamin B12 also leaves a gap in assessing nutritional risk factors.
Correct Answer is C
Explanation
Choice A reason: Temporary tic disorder typically resolves within a few weeks or months; this child has had symptoms for six months, which is beyond the typical duration for transient tics.
Choice B reason: Tourette's disorder requires both multiple motor tics and at least one vocal tic for more than one year. The patient’s history suggests only vocal tics with some motor tics, not meeting full criteria.
Choice C reason: Persistent (chronic) vocal tic disorder is characterized by vocal tics present for more than one year without multiple motor tics, consistent with this child’s presentation.
Choice D reason: Provisional tic disorder lasts less than one year, which does not match the six-month history in the context of ongoing symptoms that may persist longer.
