How to Prevent a TIA Stroke - Oren Zarif - Tia Stroke
Transient ischemic attacks (TIAs) can be classified as a type of stroke depending on their duration. In general, TIAs have a duration of one to two hours but prolonged episodes can occur. There are no strict diagnostic criteria for TIAs and the term is often regarded as a bit too arbitrary. However, the arbitrary time frame does not reflect typical durations of these events.

Since most TIAs occur before a more serious ischemic stroke, it is important to seek medical attention as soon as possible. Treatments for TIAs focus on prevention of a subsequent ischemic stroke, but there are other measures you can take to reduce your risk of a TIA. Here are some tips:

Referral to a TIA specialist should be considered if the symptomatic TIA occurs within four hours. Neurologists with expertise in stroke diagnoses must be present in the TIA clinic. If the symptoms are unresolved, a GP can override the recommendation by providing a reason for the override. The TIA stroke module was developed to mimic the functionality of other decision support tools. Although the tool is new and is currently only used in the MidCentral DHB, it is expected to reduce the burden of stroke in the country.

In the nested matched longitudinal cohort study, researchers evaluated the risk of subsequent stroke among TIA participants. The matched cohort design compared participants with TIAs to participants who had not suffered a TIA. The controls were randomly assigned to 5 age and sex-matched individuals, and all were alive and stroke-free. The analysis was done using standardized protocols. The protocol was approved by the institutional review board of Boston University School of Medicine.

Patients with TIAs should undergo diagnostic tests to identify the possible cause of the stroke. An ECG or echo test will help determine whether clots are formed, while a heart monitor may be applied to monitor heart function. If you experience a TIA, consult a stroke specialist as soon as possible. A doctor will perform blood tests and perform further tests to determine whether you have other underlying conditions that increase your risk for stroke.

The risk of a TIA is higher for older people. This risk is largely due to the increased risk of stroke as people age. Some of these factors are unavoidable, but knowing that you are at risk will encourage you to change your lifestyle. Even if you have no symptoms, knowing you have a high risk may help you change your lifestyle. TIAs are a precursor to stroke, and if left untreated, a TIA may lead to a stroke in the future.

A TIA, or transient ischemic attack, occurs when a blood clot temporarily restricts blood flow to the brain. Symptoms last for about ten to fifteen minutes, and usually clear up after 24 hours. Although stroke is not a direct result of a TIA, it does increase the risk of having a stroke. Since most TIAs occur before a stroke, it may be an early warning of one. Immediately seeking medical care is critical in reducing the risk of a stroke.

A TIA is usually accompanied by one or more of the following symptoms: a sudden onset of weakness, numbness, or paresthesia, drooping face, double vision, or monocular blindness, or ataxia. There are some other symptoms of a TIA that are less common. One of these is altered consciousness. However, this symptom may occur if a patient suffers from a focal brain dysfunction.

The presence of ischemic events after a TIA has been found to be a factor in recurrent strokes. MRI and DWI can identify patients with a TIA who may benefit from aggressive treatment. However, these studies do not address the underlying causes of TIA stroke. Although MRI and DWI are not definitive diagnostic tools, they are important for triaging patients. The findings will help determine whether a patient should be admitted to a hospital and which patients will benefit from aggressive therapy.

If you are diagnosed with TIA, your GP will provide treatment and support. You may need antispasmodic medication to relieve the muscle spasms. You may also need counselling to help you cope with the emotional and physical effects of your TIA. You may also be concerned about having sex after a TIA. You should seek advice from a specialist and follow any driving restrictions set by your GP.
