Examination reveals broad-based gait with magnetic quality and no focal neurologic deficits. Cognitive screening shows mild memory impairment. MRI demonstrates ventriculomegaly with normal ventricular-to-brain ratio and minimal cortical atrophy. CSF opening pressure is normal. Which diagnosis best explains this clinical triad?
- A)Frontotemporal dementia
- B)Vascular dementia
- C)Alzheimer disease
- D)Normal pressure hydrocephalusGABARITO

The classic triad is gait disturbance, urinary incontinence, and cognitive impairment, with enlarged ventricles and normal opening pressure on lumbar puncture. The gait problem often appears first and may improve after... Ver explicação completa e trilha adaptativa →
