Billy Joel Cancels Tour Over Brain Disorder: A Neurosurgeon Explains

Rock icon Billy Joel, who is 76 years old, has recently been diagnosed with normal pressure hydrocephalus (NPH), a neurological condition that has led to the cancellation of his upcoming tour. NPH, often mistaken for dementia, can have a significant impact on walking, balance, and cognitive function.

### What Is Normal Pressure Hydrocephalus?

The brain consists of brain tissue, blood, and cerebrospinal fluid (CSF). CSF circulates through the brain and spinal cord, providing cushioning and nutrients. In NPH, there is a problem with the absorption of CSF, leading to fluid buildup in the ventricles. This buildup puts pressure on the surrounding brain tissue, causing symptoms that can be mistaken for dementia.

NPH is relatively rare, with a higher prevalence in older adults, especially those over 80 years old.

### How Does Normal Pressure Hydrocephalus Occur?

In NPH, the primary issue is inadequate absorption of CSF, often due to dysfunction in the arachnoid granulations. These structures are responsible for absorbing spinal fluid back into the venous system. Unlike other forms of hydrocephalus that involve blockages, NPH typically presents with normal intracranial pressure.

### What Are The Symptoms of Normal Pressure Hydrocephalus?

NPH symptoms develop gradually and can resemble other conditions like Parkinson’s disease or dementia. The hallmark symptoms, known as Hakim’s triad, include gait disturbance, urinary incontinence, and cognitive impairment. Gait difficulties are the most common symptom, affecting a majority of patients. Cognitive symptoms may include slowed thinking and forgetfulness, while urinary issues can involve urgency or incontinence.

### How Is Normal Pressure Hydrocephalus Treated?

NPH does not respond to medication. Treatment focuses on removing excess CSF to alleviate symptoms. Diagnosis often involves a lumbar puncture to measure CSF pressure and remove fluid. If positive results are seen, patients may undergo ventriculoperitoneal (VP) shunt surgery. This procedure involves placing a catheter in the brain to regulate CSF flow and divert it to the abdominal cavity for absorption.

### What Is The Prognosis?

NPH is partially treatable, with shunt surgery improving symptoms in many patients. However, not all symptoms may resolve, and outcomes vary. Accurate diagnosis is crucial, as NPH can mimic dementia and may coexist with other neurodegenerative conditions.

### What Are The Next Steps For Billy Joel?
