Subarachnoid Hemorrhage

A subarachnoid hemorrhage develops when there is bleeding in the subarachnoid space. This is the area between the brain and the surrounding membrane. The hemorrhage has a sudden onset. The first symptom is usually a severe headache that may be accompanied by nausea or vomiting. Patients experiencing this hemorrhage might briefly lose consciousness. In some cases, patients may feel a popping sensation in their head just before the hemorrhage begins. Seizures, confusion, and numbness throughout the entire body could occur after this.

Serious head injuries such as falls and injuries from car accidents could lead to a subarachnoid hemorrhage. Blood thinners or an underlying medical condition such as an arteriovenous malformation can also cause this condition. This condition is considered a medical emergency. At the hospital, doctors will perform a physical examination and take CT scans or MRI scans. A cerebral angiography test may be performed as well. Surgical procedures will be carried out to reduce the buildup of pressure in the brain and to stop the bleeding.
