A 76-year-old man is brought by his family to your clinic with new-onset urinary incontinence.

Comprehensive and Detailed Explanation:

This patient presents with the classic triad of normal pressure hydrocephalus (NPH): gait disturbance (often wide-based and magnetic), cognitive decline, and urinary incontinence. The combination, especially with the gait being most prominent, is highly suggestive.

Toronto Notes 2023 – Geriatrics / Neurology:

“NPH presents with gait disturbance, dementia, and urinary incontinence. Gait is typically broad-based and magnetic. Imaging shows ventriculomegaly without elevated pressure.”

MCCQE1 Objectives (Geriatrics > 41-1: Cognitive Disorders):

“Candidates must identify NPH and distinguish it from other dementias based on clinical triad and gait features.”

Alzheimer’s (B) primarily presents with memory loss. Parkinson’s (A) has bradykinesia and rigidity. Lewy body dementia (C) includes visual hallucinations and fluctuating cognition. FTD (E) has personality and behavioral changes.
