Definition Return to top
Stroke related to cocaine use is a blockage in the blood supply to the brain and loss of brain function in someone who has used the drug, cocaine.
Causes Return to top
Cocaine is a product of the coca plant and an illegal recreational drug. It is a strong stimulant that increases activity of the central nervous system and the nerves that run away from the spinal cord (peripheral nervous system).
Cocaine use can cause a number of medical problems. Stroke related to cocaine probably occurs because cocaine causes blood vessels to narrow (constrict) while it increases blood pressure (hypertension). This vasoconstriction can be severe enough to reduce or block blood flow through the arteries in the brain. Cocaine use also can lead to swelling (inflammation) of the arteries of the brain.
Stroke related to cocaine is most common in men under 40 years old. A history of recent cocaine use is a risk.
A few people who experience stroke after using cocaine have an arteriovenous malformation, which may make them more likely to have a stroke. In these cases the stroke is due to bleeding in the brain instead of decreased blood flow.
Symptoms Return to top
Symptoms of cocaine use may include:
Symptoms of a stroke include:
Exams and Tests Return to top
Your health care provider will take a medical history of your symptoms and history of cocaine use.
You also may have signs of other disorders that occur with cocaine use.
Tests may include:
Treatment Return to top
Treatment may include not just the stroke, but also other disorders that may occur from cocaine use.
A person who is in a coma may need life support, including tubes in the airway and a breathing machine (mechanical ventilation).
It is important to stop using cocaine. Treat cocaine addiction and any other addictions. Treatment should include monitoring for signs of cocaine withdrawal.
Because most people who are addicted to cocaine are also addicted to other drugs (such as alcohol or heroin), withdrawal symptoms from these drugs should also be treated. Patients who are taking methadone for heroin addiction should continue to receive their regular dose.
Outlook (Prognosis) Return to top
The outcome depends on:
The outcome is often poor, especially with long-term cocaine use. It is possible to die if many body systems stop functioning properly.
Possible Complications Return to top
See stroke for a list of complications.
When to Contact a Medical Professional Return to top
Go to the emergency room or call 911 if you have any symptoms of stroke.
Prevention Return to top
Do not use cocaine to prevent having a stroke related to cocaine use.
