Visceral CLET IRAT 3 Practice Test

Some headache patterns have specific triggers, and alcohol is a well-known trigger for cluster headaches. Cluster headaches are intense, unilateral around the eye or temple, often occurring in short bursts called clusters and accompanied by autonomic symptoms like tearing or nasal congestion. During a cluster period, the body’s pain and circadian regulation circuits—especially the trigeminal autonomic pathways—are particularly reactive, so even a small amount of alcohol can provoke an attack. The other headache types don’t have this consistent, characteristic link to alcohol: tension-type headaches are typically tied to stress or fatigue and aren’t specifically alcohol-triggered, migraine can be triggered by alcohol in some people but the classic teaching emphasizes its association with cluster headaches, and hypertensive headaches aren’t a distinct, routinely triggered category.
