Incidence of temporal thumb sign in adult patients with idiopathic seizures with and without elevated opening cerebrospinal fluid pressure.

Summary: Have you ever heard of the "Temporal Thumb Sign"? It is a special mark doctors can see on brain scans where a small part of the brain pokes down, almost like a thumb. Doctors looked at the brain scans of 157 adults who suffer from seizures. They found that this "thumb sign" shows up almost all the time (over 92% of the time) in people who have both seizures and high pressure in their brain fluid. This is a big deal! It means emergency room doctors can use a simple, quick brain scan to spot high brain pressure early and help patients get the right treatment faster.
