Cocaine-Induced Headache: A Review of Pathogenesis, Presentation, Diagnosis, and Management

Cocaine is a vasoactive substance, and its consumption has increased throughout the world. There are many neurological complications caused by chronic cocaine use, which include headache, aneurysmal formation, ischemic stroke, hemorrhagic stroke (subdural and subarachnoid hemorrhage), seizures, etc. Headache is one of the most common symptoms that appear after cocaine use. It may occur due to dopaminergic and serotoninergic system impairment. Cocaine causes vasoconstriction by stimulation of the sympathetic nervous system and decreases the reuptake of epinephrine, norepinephrine, serotonin, and dopamine. Reversible cerebral vasoconstriction syndrome (RCVS) is well accepted with cocaine use, which occurs most commonly in middle-aged adults and females. The relation between cocaine consumption and time of occurrence of headache has been described according to which some people suffer from headaches immediately after the cocaine use, some within 40 to 90 minutes of a cocaine binge, and some even after the cocaine abstinence for long period. The diagnosis of a cocaine-induced headache depends on history, physical examination, and cerebrovascular imaging findings. And its management is done according to cause that is responsible for headache.
