Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Pick out the triad: frequent falls (a gait disturbance), behavioral change with cognitive decline, and enuresis (urinary incontinence).
Step 2: Gait disturbance + dementia + urinary incontinence is the classic triad of normal pressure hydrocephalus (often remembered as wet, wacky and wobbly).
Why not the others: Frontotemporal dementia is dominated by early personality, behavior and language changes, not the falls-plus-incontinence triad. Parkinson's disease presents with resting tremor, rigidity and bradykinesia, not enuresis as a core feature. Alzheimer's disease is mainly progressive memory loss and confusion, without the early gait and bladder triad.
