Normal pressure hydrocephalus presenting as delusional disorder

Area of Science:

• Neurology
• Neuroscience
• Psychiatry

Background:

• Normal pressure hydrocephalus (NPH) is a neurological condition characterized by impaired cerebrospinal fluid absorption.
• Aqueductal stenosis is a common cause of NPH, leading to increased intracranial pressure.
• NPH classically presents with a triad of gait disturbance, cognitive impairment, and urinary incontinence.

Observation:

• A female patient in her 50s presented with new-onset delusions.
• The patient also exhibited gait disturbances and urinary incontinence.
• These symptoms raised suspicion for an underlying organic cause.

Findings:

• The patient's symptoms were consistent with Normal pressure hydrocephalus (NPH).
• Late-onset psychosis requires thorough evaluation to exclude organic etiologies.
• This case underscores the importance of considering NPH in patients with psychosis and neurological symptoms.

Implications:

• Diagnosing and treating NPH can reverse or improve neurological deficits and psychosis.
• Early identification of NPH can prevent irreversible neurological damage.
• This case contributes to the understanding of NPH as a treatable cause of late-onset psychosis.
