title: Spontaneous subarachnoid hemorrhage.
abstract: Sudden development of pain in the head followed by evidences of meningeal irritation, with or without motor or sensory symptoms or signs, is almost pathognomonic of subarachnoid hemorrhage. The final diagnosis rests upon the demonstration of blood in the cerebrospinal fluid. If the hemorrhage is massive, or from an aneurysm of an unprotected arterial trunk, the patient may die in a comparatively short time. If the bleeding is less abundant and from an aneurysm which is protected by adjacent structures the patient may survive. Angiography should probably be done early in most cases. If neurological signs or the results of angiography indicate that the aneurysm is in such a location that surgical treatment is feasible it should probably be undertaken. If medical treatment is to be carried out the patient should have protracted rest, frequent spinal drainage so long as the cerebrospinal fluid contains blood or is under materially increased pressure, sedatives and analgesics, and passive movements of the neck and limbs to forestall limitation of motion of joints.
