Another great journal article from Andrew L. Callen MD and Kyle Jenkins MD
“Most patients with CSF pressure disorders don't read the textbook.
This review is about what to do when the imaging, symptoms, and physiology don't line up, and why "high" vs "low" pressure is often the wrong framework.”
Plain Language Summary
Many patients with chronic headache have symptoms and brain imaging findings that do not clearly fit the “high” or “low” spinal fluid pressure categories. This review explains how changes in the cushioning of the brain, blood flow through the vessels of the brain, and spinal fluid flow can produce symptoms that change over time or overlap; helping to explain why diagnosis and treatment are often uncertain. Recognizing and understanding these shared mechanisms can help clinicians better interpret subtle imaging findings and guide care for patients whose headaches have gone unexplained.

Objective This study was conducted to provide a clinically oriented, mechanism-based framework for interpreting neuroimaging across disorders of cerebrospinal fluid (CSF) pressure, with particular e...
