What Are Some Diseases Of The Brain – Reviewed by Dr. Payal Kohli, M.D., FACC – Kimberly Holland – Updated November 9, 2021
Recognizing the symptoms of a stroke and finding prompt treatment can lead to better outcomes. Symptoms may appear inattentively and may include drowsiness, weakness or paralysis and slurred speech.
What Are Some Diseases Of The Brain
A stroke occurs when blood vessels in the brain rupture and bleed, or when blood flow to the brain is blocked. A crack or blockage prevents blood and oxygen from reaching the brain tissue.
The Quest To Make Neurodegenerative Disease A Thing Of The Past
Stroke is the leading cause of death in the United States. Each year, more than 795,000 Americans have a stroke.
Loss of blood flow to the brain destroys brain tissue. Symptoms of a stroke occur in the part of the body controlled by the damaged part of the brain.
The sooner people with stroke receive treatment, the more likely they will have a better outcome. This is why it is helpful to know the signs of a stroke so you can act quickly. Symptoms of a stroke can include:
A stroke requires immediate medical attention. If you suspect that you or someone else is having a stroke, call 911 or your local emergency department immediately. Prompt treatment is key to preventing the following consequences:

It’s better to be extra cautious when dealing with a stroke, so don’t be afraid to seek emergency care if you think you recognize the signs of a stroke.
During an ischemic stroke, the blood vessels that supply blood to the brain become narrowed or blocked. Blood clots or rapid flow to the brain cause these blockages. Pieces of plaque that break off and block arteries can also cause them.
A blockage of a cerebral artery (often called a stroke) occurs when blood clots form in other parts of the body — often in the heart or blood vessels in the upper chest and neck — and travel. Follow the blood flow until it touches a vein that is too narrow to allow. It will pass.
A blood clot in the brain (often called a blood clot) occurs when a blood clot forms on a plaque in a blood vessel.
Nervous System Disease
A transient ischemic attack, often called a TIA or mini-stroke, occurs when blood flow to the brain is temporarily blocked.
The symptoms are similar to those of a complete stroke. However, they are usually temporary and go away after a few minutes or hours as the blockage moves and blood flow returns.
Blood clots usually cause a TIA. Although not technically classified as a full-blown stroke, a TIA serves as a warning that an actual stroke may be occurring. Because of this, it is better not to be indifferent. Find the stroke treatment you want and get first aid.
More than a third of people who have had a TIA and have not been treated have had a major stroke within a year. As many as 10 to 15 percent of TIA patients experience a major stroke within 3 months.

A stroke occurs when a blood vessel in the brain ruptures or bleeds. The blood coming out of the arteries increases the pressure on the skull and swells the brain, destroying brain cells and tissues.
If you drink, drink in moderation. This means no more than one glass a day for women and no more than two glasses a day for men.
Excessive alcohol consumption can raise blood pressure. It can also increase triglyceride levels, which can cause atherosclerosis. This is a build-up of plaque in the narrowed arteries.
Tobacco use in any form also increases the risk of stroke as it can damage blood vessels and the heart. Nicotine also raises blood pressure.

Can vary. They can be caused by direct brain damage during a stroke or because ability is permanently affected.
Lifestyle changes do not prevent all strokes. But many of these changes can make a big difference in reducing the risk of stroke.
Your doctor will ask you or a family member about your symptoms and what you do when they wake up. They will take your medical history to look for your stroke risk factors. They also:
Your doctor will then perform special tests to confirm the diagnosis of stroke. These tests can help them determine if you have a stroke and if:

Your doctor may order tests to help them determine if you have a stroke or rule out another condition. These tests include:
A CT scan can give a detailed and accurate picture of your brain, which can show bleeding or damage. It may also indicate other brain conditions that may be causing your symptoms.
An electrocardiogram (ECG) is a simple test that records the heart’s electrical activity, measures its rhythm, and records the heart’s rate.
An EKG can determine if you have a heart condition that can lead to a stroke, such as a previous heart attack or atrial fibrillation.

Cerebral artery examination gives a detailed picture of the arteries of the neck and brain. The test can show a blockage or blood clot that can cause symptoms.
An ultrasound of the carotid artery, called a bidirectional carotid scan, can show a layer of fat (plaque) in your carotid artery, which supplies blood to your face and brain.
An ultrasound can find the source of the blood clot in your heart. These blood clots can travel to your brain and cause a stroke.
Accurate medical evaluation and prompt treatment are critical to stroke recovery. According to the American Heart Association and the American Stroke Association, “time lost is brain lost.”

Call 911 or your local emergency department as soon as you know you are having a stroke or if you suspect someone is having a stroke.
Because blood clots or blockages in the brain cause these types of strokes, they are widely treated with similar techniques. They may include:
Thrombolytic drugs can break up blood clots in your arteries, stopping a stroke and reducing brain damage.
People who receive a tPA injection are more likely to recover from a stroke and are less likely to have long-term disability as a result of the stroke.

During this procedure, the doctor inserts a catheter into a large artery inside the head. Then they use tools to pull the clot out of the vein. This surgery is most successful if done.
If the doctor finds where the artery wall is weak, he or she may perform a procedure to inflate the artery and support the artery wall with a stent.
In rare cases when other treatments don’t work, surgery can remove blood clots and plaque from your arteries.
This surgery can be done using a catheter. If the blood clot is large, the surgeon in particular may open the artery to remove the blockage.

Strokes caused by hemorrhage or cerebral hemorrhage require different treatment strategies. Treatments for stroke include:
Unlike an ischemic stroke, if you have a stroke, the goal of treatment is to freeze the blood. So you may be given medication to prevent blood clots that you are taking.
During this procedure, your doctor will insert a long tube into the area of bleeding or atherosclerosis. Then they install a device that looks like a coil in the area where the vein wall is weakening. This blocks blood flow to the area and reduces bleeding.
To prevent further bleeding, the surgeon may place a small clamp at the base of the anus. This cuts off the blood flow and prevents a possible stroke or new bleeding.

If your doctor finds a blood clot, he or she may perform surgery to close the anus and stop the bleeding. Similarly, craniotomy may be necessary to relieve pressure on the brain after a stroke.
Many drugs are used to treat stroke. The type your doctor prescribes depends on the type of stroke.
Some drugs aim to prevent a second stroke, while others aim to prevent a stroke in the first place.
Your doctor may prescribe one or more of these drugs to treat or prevent stroke, depending on factors such as your medical history and risk.

It works in the same way as traditional anticoagulants (weakens the blood’s ability to clot), but they are often faster and require less monitoring.
This emergency medicine can be given during a stroke to break up the blood clots that cause the stroke. It is the only drug available, but it must be given within 3 to 4.5 hours of the onset of stroke symptoms.
The medicine is injected intravenously so that the medicine can start working as quickly as possible, which reduces the risk of complications from stroke.
These drugs can also prevent existing blood clots from growing, which is why doctors may prescribe them for stroke prevention or after an ischemic stroke or TIA.
