A sudden, severe headache — so powerful it’s like a thunderclap inside your head — is a classic symptom of a less common type of stroke.
Aneurysmal subarachnoid hemorrhage (aSAH) is a bleeding stroke. Survivors often describe the “thunderclap headache” as “the worst headache of my life.” It occurs most in people 40 to 60 years old.
Most people don’t recognize the symptoms, say American Stroke Association experts.
Besides the thunderclap headache, symptoms can include vomiting, confusion, loss of consciousness and seizures. Neck stiffness may also occur several hours after the onset of the headache.
If you experience any of these symptoms, don’t waste time trying to figure what it is. Go to the emergency room.
