Transient ischemic attacks (TIAs) are mini strokes caused by a lack of blood flow to the brain. The symptoms vary, ranging from mild changes in mental acuity and speech to obvious loss of sensation and coordination. Because the symptoms are temporary, it is important to see a physician if you have them. If you suspect a stroke, contact 911 immediately and have yourself evaluated by a medical professional.

Hemorrhagic strokes can also cause loss of consciousness and increased intracranial pressure. Another type of stroke is subarachnoid hemorrhage, which occurs when blood leaks into the space surrounding the brain. If you suspect a stroke, call triple zero (000) and ask for an ambulance. If you’re still unsure, use the Symptom Checker to check whether you’re having any of the symptoms of a stroke.

Another sign of a stroke is a sudden, severe headache that is accompanied by dizziness, vomiting, and altered consciousness. People experiencing a stroke may also have difficulty speaking or concentrating, or they might have difficulty repeating simple sentences. If you notice any of these symptoms, call 911 immediately, and make sure you note when the symptom started. In the meantime, try to reduce the likelihood of having a stroke by making sure you’re not eating too much or drinking too much.

Seizures may occur within the first few hours or days after a stroke, and may occur months or years later, due to scarring or deposits of blood in the damaged brain tissue. The symptoms of a stroke can also include a fever. If you experience a fever, it’s important to contact your doctor as soon as possible.

Rehabilitation is a very important part of stroke treatment. The goal of rehabilitation is to regain function and prevent a recurrence of the stroke. In many cases, it’s possible to return to a normal lifestyle after a stroke. Rehabilitation involves limiting saturated fats in the diet, lowering cholesterol, and maintaining a healthy blood pressure. There are also anticoagulant medications available for stroke patients to reduce the risk of a recurrence.

The cerebellum is the area of the brain that processes input from other areas of the brain, as well as from the spinal cord and sensory receptors. The cerebellum is responsible for precise timing of coordinated movement, and a stroke in this area can affect balance and coordination. The cerebellum is connected to the internal carotid arteries, which branch out into smaller arteries and supply oxygenated blood to over 80% of the cerebrum.

The brain is supplied with oxygen via the carotid arteries, and clots can build up in the arteries. Neurosurgeons treat clots in these arteries using procedures known as carotid endarterectomy and carotid artery angioplasty and stenting. Some stroke patients may need the assistance of a ventilator to breathe. Moreover, patients may need to undergo physical rehabilitation after a stroke.

If you or a loved one has symptoms of a CVA, make sure to get an exam. Doctors will ask you to describe your symptoms and check your physical functions. They will also check your blood pressure and listen for any abnormalities in the carotid arteries. If the carotid arteries are obstructed, they will use an electrocardiogram to determine the cause of the clot.

High blood cholesterol levels can cause blood clots to form in the arteries. This can cause a blockage of blood flow to the brain. A blocked blood vessel can cause a stroke. People with high blood pressure have a higher risk of a stroke than those with normal blood pressure. It is important to get regular blood pressure checks as early as possible to ensure that your blood pressure is not too high.

A CVA stroke is life-threatening. The brain stem controls breathing and heartbeat and a stroke in this area is life-threatening. Symptoms may include double vision, nausea, and loss of coordination. Symptoms can vary from person to person, and may continue to worsen over time. If you notice any of these symptoms, contact your doctor or seek immediate medical attention.
