The Hidden Emotional Toll of Hydrocephalus: New Research Sheds Light on Psychiatric Symptoms
Idiopathic normal pressure hydrocephalus (iNPH), a condition often associated with gait disturbance, cognitive decline, and urinary incontinence, is increasingly recognized for its significant neuropsychiatric impact. A recent systematic review and meta-analysis, published in Neurology: Clinical Practice, reveals a surprisingly high prevalence of depression and apathy in iNPH patients, prompting calls for more comprehensive assessment and treatment strategies.
Understanding the Link Between iNPH and Mental Health
For years, the focus in iNPH management has been largely on the physical symptoms. Still, emerging research, spearheaded by Clara Belessiotis-Richards, MBBS, of King’s College London, demonstrates that the emotional and behavioral consequences are equally important. The study found that over 30% of iNPH patients experience depression, while a striking 69.2% exhibit apathy – a lack of motivation or interest in activities.
This isn’t entirely unexpected. Neurodegenerative diseases like Alzheimer’s and Parkinson’s are well-known for their psychiatric manifestations. Researchers are now understanding that iNPH, while distinct, can present with similar emotional disturbances. The study team noted that psychiatric symptoms can significantly impact quality of life, and understanding their prevalence in iNPH is crucial.
What the Research Reveals: A Deep Dive into the Data
The meta-analysis, encompassing 22 studies and a combined total of over 7,670 patients, provides a robust overview of neuropsychiatric symptoms in iNPH. Beyond depression and apathy, the research identified other prevalent issues, including anxiety (21.9%), disinhibition (21.0%), and agitation (22.6%). Less common, but still present, were psychotic syndromes (8.0%).
Interestingly, the study similarly investigated the impact of shunt insertion – a common surgical treatment for iNPH – on these symptoms. While shunt insertion showed a small reduction in depression scores, the effect wasn’t statistically significant. However, one study included in the analysis did present an overall reduction in neuropsychiatric symptom burden following shunting.
Pro Tip: Early detection of neuropsychiatric symptoms in iNPH is vital. If you or a loved one is experiencing changes in mood, motivation, or behavior alongside physical symptoms, consult a healthcare professional.
Future Directions: The Need for Targeted Research
The findings underscore a critical gap in our understanding of iNPH. Researchers emphasize the urgent need for further investigation into the underlying mechanisms linking iNPH to neuropsychiatric symptoms and, crucially, how these symptoms respond to different treatment approaches.
Clara Belessiotis-Richards is currently undertaking a study combining neuroimaging analytics and epidemiology to understand normal pressure hydrocephalus in memory services, suggesting a focus on the brain’s structural and functional changes related to these symptoms. This type of research could pave the way for more targeted therapies.
The Role of Neuroimaging and Big Data
Clara Belessiotis-Richards’ work at King’s College London specifically focuses on analyzing neurobiological data within large-scale epidemiological datasets. This approach, leveraging the power of “big data,” is expected to be instrumental in identifying biomarkers and risk factors for neuropsychiatric symptoms in iNPH.

Frequently Asked Questions (FAQ)
Q: What is iNPH?
A: Idiopathic normal pressure hydrocephalus is a condition characterized by an abnormal buildup of cerebrospinal fluid in the brain’s ventricles, leading to neurological symptoms.
Q: Are neuropsychiatric symptoms always present in iNPH?
A: No, not all iNPH patients experience neuropsychiatric symptoms, but they are common, with depression and apathy being particularly prevalent.
Q: Can shunting completely resolve neuropsychiatric symptoms?
A: Shunting may improve some symptoms, but the research suggests the effect on neuropsychiatric symptoms is often small and not always statistically significant.
Q: Where can I find more information about iNPH?
A: You can find more information from organizations like the Hydrocephalus Association: https://www.hydroassoc.org/
