In Ichinoseki shi, Iwate, a 15 year old student died of subarachnoid hemorrhage at his junior high school.
A subarachnoid hemorrhage, or subarachnoid haemorrhage in British English, is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. This may occur spontaneously, usually from a ruptured cerebral aneurysm, or may result from head injury.
Symptoms of SAH include a severe headache with a rapid onset (“thunderclap headache”), vomiting, confusion or a lowered level of consciousness, and sometimes seizures. The diagnosis is generally confirmed with a CT scan of the head, or occasionally by lumbar puncture. Treatment is by prompt neurosurgery or radiologically guided interventions with medications and other treatments to help prevent recurrence of the bleeding and complications. Surgery for aneurysms was introduced in the 1930s, but since the 1990s many aneurysms are treated by a less invasive procedure called “coiling”, which is carried out by instrumentation through large blood vessels.
SAH is a form of stroke and comprises 1–7% of all strokes. It is a medical emergency and can lead to death or severe disability—even when recognized and treated at an early stage. Up to half of all cases of SAH are fatal and 10–15% of casualties die before reaching a hospital, and those who survive often have neurological or cognitive impairment. SOURCE
