Thunderclap Headache
A thunderclap headache is a severe, sudden-onset headache that reaches its peak intensity within 60 seconds. Often described as the “worst headache of your life,” this type of pain is distinct from other headaches due to its abrupt and explosive nature. It can occur without warning and is frequently associated with serious underlying conditions, making it a medical emergency that requires immediate attention.
Common Causes of Thunderclap Headache
- Subarachnoid hemorrhage: Bleeding in the space surrounding the brain, often caused by a ruptured aneurysm.
- Reversible cerebral vasoconstriction syndrome (RCVS): A condition where blood vessels in the brain suddenly constrict.
- Intracranial hypotension: Low cerebrospinal fluid pressure, often due to a spinal fluid leak.
- Stroke or ischemic events: Disruption of blood flow to the brain.
Because a thunderclap headache can signal life-threatening conditions, it is crucial to seek immediate medical evaluation if you experience this symptom. Diagnostic tests such as CT scans, MRIs, or lumbar punctures are often necessary to identify the cause and initiate appropriate treatment.
