Cerebrovascular diseases
Cerebrovascular diseases (/ˌsɛrɪbroʊˈvæskjʊlər/; from Latin cerebrum, meaning "brain", and vasculum, meaning "vessel") are a group of conditions, disorders, and diseases that affect the blood vessels and blood supply to the brain.
Types of Cerebrovascular diseases
Cerebrovascular diseases include several different medical conditions:
- Stroke - A condition where the blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients.
- Transient Ischemic Attack (TIA) - Often called a mini-stroke, it's a temporary period of symptoms similar to those of a stroke.
- Subarachnoid Hemorrhage - A condition where there is bleeding in the space surrounding the brain.
- Cerebral Aneurysm - A condition where there is a weak spot in a blood vessel in the brain that balloons and fills with blood.
- Arteriovenous Malformation (AVM) - A condition where there is a tangle of abnormal blood vessels connecting arteries and veins in the brain.
Symptoms
Symptoms of cerebrovascular diseases can vary depending on the specific condition but may include headache, dizziness, confusion, weakness or numbness on one side of the body, difficulty speaking or understanding speech, and loss of vision in one or both eyes.
Causes
Cerebrovascular diseases are often caused by atherosclerosis, hypertension, diabetes, smoking, and high cholesterol. These conditions can damage blood vessels in the brain, leading to cerebrovascular diseases.
Treatment
Treatment for cerebrovascular diseases depends on the specific condition and may include medication, surgery, physical therapy, and lifestyle changes such as diet and exercise.
