From the Research
Yes, an increase in frequency of urination and a foggy feeling can be related to Normal Pressure Hydrocephalus (NPH). NPH is characterized by a classic triad of symptoms: urinary incontinence, gait disturbance, and cognitive decline, as noted in a study published in 2020 1. The urinary symptoms often begin as increased frequency or urgency before progressing to frank incontinence, as seen in a case study from 2007 2. The "foggy feeling" likely represents the cognitive impairment component of NPH, which can manifest as confusion, memory problems, slowed thinking, or a general feeling of mental cloudiness.
Key Symptoms of NPH
- Urinary incontinence
- Gait disturbance
- Cognitive decline
These symptoms occur because excess cerebrospinal fluid accumulates in the brain's ventricles, putting pressure on nearby brain tissue responsible for bladder control, walking, and cognitive function, as explained in a review of the pathogenesis and pathophysiology of iNPH 1. The condition is called "normal pressure" because the cerebrospinal fluid pressure may appear normal during a single measurement, despite the chronic problem of impaired fluid absorption.
Importance of Early Diagnosis and Treatment
If you're experiencing these symptoms, it's essential to seek medical evaluation promptly, as NPH can be treated with surgical placement of a shunt to drain excess fluid, as demonstrated in a case report from 2023 3. Early diagnosis and treatment often lead to better outcomes, with some patients experiencing significant improvement in their symptoms after appropriate intervention. A systematic review published in 2025 4 highlights the importance of standardizing the large-volume "tap test" for evaluating idiopathic normal pressure hydrocephalus, which can help determine a patient's potential to benefit from shunt placement.
Next Steps
Given the potential for significant improvement with treatment, it is crucial to consult a neurologist or a multidisciplinary team for a comprehensive evaluation if symptoms suggestive of NPH are present, as the latest and highest quality study suggests 4.
