Transient ischemic attacks (TIAs) are mini strokes caused by reduced blood flow to the brain. They often precede an actual stroke and can present with a variety of symptoms. These symptoms range from a mild change in mental acuity to obvious weakness or loss of sensation. A person may also experience blurred or double vision, as well as difficulty speaking or swallowing. If you have any of these symptoms, contact a qualified physician immediately.

A person who has had a TIA is at a higher risk of a stroke. TIAs are shorter-lived than strokes, but can be frightening and debilitating. People with TIAs are nearly 10 times more likely to have a full-blown stroke than someone who has never suffered a TIA. They also have a high red blood cell count, which thickens the blood and increases clotting risk.

Other symptoms of a CVA include a sudden and severe headache, dizziness, and an altered level of consciousness. A person with a stroke may also have difficulty speaking or may have difficulty with balance. It can be difficult to understand a person who has experienced a stroke. To determine if a person has suffered a stroke, a healthcare provider will conduct a full physical exam. The health provider will check the strength of the person’s muscles, reflexes, and senses. They will also check the blood pressure of the person to ensure it is high.

Imaging tests are important in the diagnosis of a CVA. The tests help determine whether blood clots are forming in the brain. Imaging tests may also help doctors determine if there is another underlying condition. They may also find an infection or blood clotting problem. Regardless of how severe the symptoms, it is important to seek medical attention as soon as possible. The sooner you receive medical care, the faster you can recover from the complication.

A stroke can have many different types. The most common type is ischemic, in which a blood clot or atherosclerotic plaque blocks the blood flow to the brain. Hemorrhagic stroke is a more serious condition in which a blood vessel ruptures and causes pressure to the nearby brain tissues. If the brain stem is affected, it can result in a stroke affecting the heart and breathing. It can also cause nausea and double vision, and may affect coordination.

If the symptoms of a CVA stroke are severe, it is important to see a doctor as soon as possible. Medications such as tPA are used to dissolve the clot and allow the blood to flow again. In some cases, a specialized doctor may perform a mechanical thrombectomy. This procedure involves threading a catheter through a blood vessel in the groin. During the procedure, a specialized doctor uses a clot retrieval device to remove the clot.

A ruptured blood vessel in the brain can result in a hemorrhagic stroke. The ruptured blood vessel causes damage to the brain tissue and may require emergency medical treatment. This type of stroke is the most severe type, and is associated with more serious symptoms. Among these types of stroke are intracerebral hemorrhages and subarachnoid hemorrhages. Hemorrhagic strokes occur when a blood-filled pouch ruptures between the brain and the skull.

Despite these risks, the onset of another stroke is highly preventable. By adopting a healthy diet and taking medication to control risk factors, you can reduce the risk of having a stroke. For example, reducing your saturated fat intake and limiting your sodium intake can significantly reduce the risk of having another CVA stroke. Similarly, regular exercise can help improve circulation. You may also want to consult your doctor if you have a family history of stroke.

If you notice any of these symptoms, call 911 immediately. Do not drive to the hospital if you suspect you are experiencing a stroke. The emergency medical team will be able to begin life-saving treatment as soon as possible. Depending on the type of stroke, your treatment may include medication, surgery, or a procedure. Once you have been treated, you may need a rehabilitation program to recover from the stroke. Your doctor will work with you to determine the most appropriate treatment.
