Hemorrhaging into the area between the outer and middle layers of the membranes encasing the brain, typically occurring after a head injury. The confined blood creates a sizable clot inside the skull, exerting pressure on the brain tissue.
Indications and manifestations have a tendency to change in intensity and might encompass a headache, disorientation, drowsiness, and weakness or paralysis on one side of the body. The bleeding transpires gradually, with the timeframe between the injury and the onset of symptoms ranging from days to months.
The diagnosis is established through CT scanning or MRI to pinpoint the location of the clot. Often, surgery becomes necessary. This procedure entails creating burr holes in the skull to release the accumulated blood and mend injured blood vessels. When treatment is administered promptly, individuals typically achieve complete recuperation. In instances where a minor subdural hemorrhage yields minimal symptoms, intervention might not be essential. The affected individual is typically subjected to regular scans for monitoring, as the clot might resolve spontaneously.
