What kind of doctor treats Cerebrovascular Disease?
Cerebrovascular disease can be treated. A neurologist, a doctor who treats brain and nerve problems, can help. A neurosurgeon may also help. That is a doctor who does brain and blood vessel surgery. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is cerebrovascular disease?
Cerebrovascular disease includes all disorders in which part of the brain is hurt by blocked blood flow or by bleeding, and one or more brain blood vessels are involved. It includes stroke, carotid stenosis, aneurysms, and vascular malformations.
When a vessel narrows, a clot blocks it, or a vessel bursts, brain cells lose oxygen. Without oxygen, brain cells can be damaged or die within minutes. This can cause lasting problems with movement, speech, or thinking.
Symptoms
Symptoms depend on the type of blood vessel problem and the part of the brain affected. Warning signs of a stroke or TIA come on suddenly and include:
- Numbness or weakness of the face, arm, or leg, often on one side of the body.
- Confusion, trouble speaking, or trouble understanding speech.
- Trouble seeing in one or both eyes.
- Trouble walking, dizziness, or loss of balance or coordination.
- A sudden severe headache with no known cause.
A TIA, or transient ischemic attack, is a brief blockage that causes stroke-like symptoms but no permanent damage. Symptoms pass quickly, but a TIA is a warning sign. A stroke that is caused by bleeding may bring a sudden headache that can be severe.
Causes and who gets it
Blood flow problems can come from vessel narrowing, clot formation, a clot that travels from elsewhere and blocks a vessel, or vessel rupture. Fatty deposits called plaque can narrow the arteries that supply the brain. This process is called atherosclerosis. An aneurysm, a weak bulge in a vessel wall, can burst and bleed.
High blood pressure is the main risk factor for stroke. Other risks include smoking, diabetes, and high cholesterol. An irregular heartbeat raises risk too. So do obesity and lack of exercise. Risk rises with age, and having had a stroke or TIA before raises the chance of another one.
How doctors diagnose it
Doctors do a physical exam and check vision, movement, reflexes, and speech. They listen to the carotid arteries in the neck for an abnormal sound called a bruit. Tests may include a CT or MRI scan of the brain, an angiogram to look for blocked or bleeding vessels, and carotid ultrasound to check for narrowing. An echocardiogram, an ultrasound of the heart, can show whether a clot from the heart caused the stroke. Blood tests and heart rhythm monitoring may also be used.
Treatment
A stroke is a medical emergency. Clot-busting medicine can treat a stroke caused by a clot, but it works only when given within 4 and a half hours of the first symptoms. Doctors may also remove a clot using a thin tube called a catheter. Bleeding strokes often need surgery to relieve pressure in the skull.
To prevent more strokes, doctors prescribe medicines that control risk factors. These include blood thinners such as aspirin, medicines for high blood pressure, and medicines that lower cholesterol. For narrowed carotid arteries, treatment may be carotid endarterectomy. That is an operation that removes plaque from the artery. Another option is carotid angioplasty and stenting. A balloon opens the artery. A small mesh tube holds it open. Rehabilitation helps people recover lost function. It can include physical, speech, and occupational therapy.
When to see a doctor
A stroke is a medical emergency. Call 911 right away at the first sign of a stroke. A quick way to remember the signs is F.A.S.T.: face drooping, arm weakness, speech difficulty, and time to call 911. Also call 911 for a sudden severe headache, sudden trouble seeing, or sudden loss of balance. A TIA is an emergency too, so call 911 even if the symptoms pass. It can warn of a major stroke in the following days.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can track blood pressure, cholesterol, and blood sugar over time and adjust prevention plans. They can also make sure you follow up after a stroke or TIA.
Common questions
What is the difference between a stroke and a TIA?
A stroke causes lasting brain damage when blood flow is cut off or a vessel bleeds. A TIA is a temporary blockage that causes stroke-like symptoms but leaves no permanent damage. Both are emergencies and need immediate medical care.
Can cerebrovascular disease be prevented?
You cannot change every risk factor, but you can lower your risk. Do not smoke. Control blood pressure, cholesterol, and blood sugar. Exercise regularly, keep a healthy weight, and limit alcohol. Treating problems like atrial fibrillation and sleep apnea also helps.
What is carotid stenosis?
Carotid stenosis is narrowing of the carotid arteries, the large arteries in the neck that supply blood to the brain. It is usually caused by plaque buildup. It often causes no symptoms until it triggers a TIA or stroke.
How well do people recover from a stroke?
Recovery depends on the type of stroke, how much brain tissue was damaged, and how quickly treatment was given. Problems with moving, thinking, and talking often start to improve in the days to weeks after a stroke. Many people keep improving for months or years.
