What Causes Thunderclap Headaches?

Blood Clot In The Brain

A blood clot is a semi-solid mass of blood cells, and they can be caused by numerous different factors. Depending on the severity and location, these clots can be life-threatening. The clot might be stationary, which is called thrombosis, or it may loosen and travel throughout the circulatory system, which is called an embolism. When located in the brain, blood clots lead to serious neurological problems, though the exact symptoms vary depending on the part of the brain affected. Patients might have trouble with speech or their vision, have seizures, or feel generally weak throughout their bodies. Blood clots can block the flow of blood to parts of the brain, leading to stroke symptoms. The lack of oxygen might lead to a thunderclap headache. Patients exhibiting stroke symptoms may be evaluated with an emergency CT scan. Doctors might also do a carotid ultrasound to see whether there's a blood clot in the neck. Sometimes part of this clot may break off and move into the brain.
