Subarachnoid hemorrhage

Symptom of subarachnoid hemorrhage

Severe headache

At the moment of hemorrhage, most people feel a sudden headache more severe than anything they have ever experienced before, as if they have been hit in the head with a baseball bat. This is because one of the roles of part of the membranes protecting the brain is to feel pain, and hemorrhage spreading through the subarachnoid space stimulates these membranes, causing intense headache. Depending on the severity of the hemorrhage, the headache may be accompanied by severe vomiting or unconsciousness. These symptoms are so specific that if you see someone suddenly complaining of a severe headache who then collapses, you should suspect they have suffered a subarachnoid hemorrhage and call an ambulance. Other symptoms such as paralysis of the arms and legs may or may not be present. This is in contrast to other forms of stroke (intracerebral hemorrhage and cerebral infarction), in which sufferers frequently have no headache, but develop motor paralysis of half of the body.

[ Severe headache caused by subarachnoid hemorrhage ]

Extraordinary severe headache occurs as if the head were struck by a baseball bat, immediately after a cerebral aneurysm ruptures.
