Question 1

What is the estimated prevalence of depression among Parkinson's disease patients?

Accepted Answer

35-50%

Answer

Depression affects approximately 35-50% of PD patients, making it one of the most common and impactful non-motor symptoms.

Question 2

Depression in Parkinson's disease is best understood as:

Accepted Answer

A non-motor symptom driven in part by neurochemical changes in monoaminergic pathways

Answer

PD-related depression is a neurobiological symptom caused by degeneration of serotonergic, dopaminergic, and noradrenergic pathways, not merely a psychological response.

Question 3

Which antidepressant class is generally considered first-line for treating depression in Parkinson's disease?

Accepted Answer

Selective serotonin reuptake inhibitors (SSRIs)

Answer

SSRIs are preferred in PD because they are effective for depression and lack the significant anticholinergic side effects of older antidepressants.

Question 4

What is the most common anxiety disorder seen in Parkinson's disease?

Accepted Answer

Generalized anxiety disorder (GAD)

Answer

Generalized anxiety disorder is the most prevalent anxiety condition in PD, characterized by persistent, difficult-to-control worry across multiple areas of life.

Question 5

Anxiety in Parkinson's disease is most strongly correlated with which motor phenomenon?

Accepted Answer

Motor fluctuations and off periods

Answer

Anxiety episodes frequently coincide with dopaminergic off periods, suggesting a direct neurochemical basis rather than a purely situational cause.
