What kind of doctor treats Transient Ischemic Attack?
A neurologist, a brain and nerve doctor, usually guides care after a transient ischemic attack (TIA). A TIA is a short block of blood flow to part of the brain. It can be a warning of a stroke, so the symptoms need emergency care first. 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 a transient ischemic attack?
A transient ischemic attack, or TIA, is often called a mini-stroke. Blood flow to part of the brain is blocked for a short time. After a TIA, the blockage breaks up and dissolves on its own.
It is a warning sign that a true stroke may happen in the future, often in the near future.
Symptoms
TIA symptoms are like stroke symptoms. They start suddenly. They can include:
- Numbness or weakness in the face, arm, or leg, especially on one side of the body.
- Trouble seeing in one or both eyes, or double vision.
- Trouble walking or dizziness.
- Confusion.
- Trouble talking or understanding speech.
- Loss of balance and coordination.
Most symptoms go away within an hour, but they may last up to 24 hours. They may come back later. No one can tell right away whether the symptoms are from a TIA or a stroke.
Causes and who gets it
A TIA happens when blood flow to part of the brain stops for a short time. Possible causes are:
- A blood clot in an artery of the brain.
- A blood clot that travels to the brain from somewhere else, such as the heart.
- An injury to blood vessels.
- Narrowing of a blood vessel in the brain or leading to the brain.
Anyone can have a TIA, but it is more common in older people. High blood pressure is the main risk factor. Other risk factors include an irregular heartbeat called atrial fibrillation, diabetes, high cholesterol, smoking, heavy alcohol use, and a family history of stroke.
How doctors diagnose it
It is possible for doctors to diagnose a TIA from your symptoms and medical history alone. They also do a physical exam to check your heart, blood vessels, nerves, and muscles. Tests may include:
- A CT scan or MRI of the brain, which are imaging tests that show pictures of the brain.
- A scan of the blood vessels, called an angiogram, to see which vessel is blocked.
- A carotid ultrasound, which shows whether the arteries in the neck have narrowed.
- An echocardiogram, which checks the heart for a source of a blood clot.
- An ECG (electrocardiogram) and heart rhythm monitoring to look for an irregular heartbeat.
Doctors may also check for high blood pressure, diabetes, and high cholesterol.
Treatment
Treatment aims to lower your chance of a stroke. If you had a TIA in the last 48 hours, you will likely be admitted to the hospital so doctors can search for the cause and watch you.
Doctors treat high blood pressure, heart disease, diabetes, high cholesterol, and blood disorders as needed. You may get medicines that prevent blood clots, such as heparin or warfarin. Your doctor decides which medicine is right for you. If you have atrial fibrillation, you will be treated for it. Some people with blocked neck arteries need surgery to clear or open the arteries.
Lifestyle changes help too. These include quitting smoking, exercising more, eating healthier foods, staying at a healthy weight, and cutting back on alcohol.
When to see a doctor
A TIA is a medical emergency. Call 911 right away if you have any of the symptoms above, including sudden weakness or numbness in the face, arm, or leg, trouble talking, a sudden change in vision, or sudden, severe pain anywhere in the body. Call an ambulance. Do not try to drive to the hospital. Do not ignore symptoms just because they go away. They may be a warning of a future stroke.
After a TIA, follow up with your doctor to manage your risk factors. Some people who have a TIA will have a stroke within 3 months. Half of these strokes happen in the 48 hours after a TIA.
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. After the emergency care, either type of doctor can help with follow-up, check blood pressure, cholesterol, and blood sugar, and coordinate a neurologist or heart doctor.
Common questions
Is a TIA the same as a stroke?
No, a TIA is not the same as a stroke. It is a warning that a stroke may come. The symptoms look alike, so you cannot tell them apart on your own.
Do I need the emergency room if the symptoms go away?
Yes, you still need emergency care. Call 911 and do not ignore symptoms just because they go away. Doctors need to look for the cause and lower your risk of a stroke.
Can a TIA lead to a stroke?
Yes, a TIA is a warning sign that you may have a true stroke in the coming days or months. About one-third of people who have a TIA will have a severe stroke sometime in the future.
How can I lower my risk of a stroke after a TIA?
You can lower your risk by following your doctor's plan to manage risk factors. This means treating high blood pressure and other health problems, and making healthy lifestyle changes.
