A 70-year-old male who is diabetic presents with gait difficulty, cognitive disturbance, and urinary incontinence. What condition is part of the differentials?

The scenario described points towards normal pressure hydrocephalus (NPH) as a pertinent differential diagnosis. NPH is characterized by the classic triad of symptoms: gait disturbances, cognitive dysfunction, and urinary incontinence.

In elderly patients, particularly those with diabetes, these symptoms may present as a result of accumulation of cerebrospinal fluid in the brain's ventricles, which can lead to increased intracranial pressure and neurological impairment. The gait difficulty often manifests as a shuffling walk or a sense of imbalance, cognitive disturbances may include memory problems or difficulties with executive function, and urinary incontinence typically arises from the disruption of normal brain signaling for bladder control.

In contrast, while Alzheimer's disease can lead to cognitive decline, it does not typically cause gait disturbances or incontinence at early stages. Multiple sclerosis might cause gait issues or cognitive changes, but is less likely to present with the combination of symptoms seen in this case and is usually associated with younger patients. Peripheral neuropathy primarily affects sensation and motor function in the extremities without producing the classic triad of symptoms seen in NPH.

Thus, normal pressure hydrocephalus is directly associated with the symptoms presented in this 70-year-old male patient, making it a strong candidate for further
