Thunderclap Headache

There have been articles in the medical literature describing a sudden, severe headache that may mimic a thunderclap in its intensity and severity. Some researchers feel it may be a warning of an impending rupture of an aneurysm or weak blood vessel. Other researchers disagree with this opinion.

Since the nature of the headache by itself cannot allow distinction between benign and serious causes, it is best to seek out prompt medical evaluation for them.
