What Is a TIA
It is often referred as mini stroke. It is being caused by ischemia which is a factor of transient episode of neurological malfunction. It affects the focal brain, retinal or the spinal cords without any exact infarction. There will be a disruption in the blood flow, which is specifically termed as the cerebral blood flow due to the strokes. Tia disease could be confirmed by analyzing any of the following symptoms, like contralateral paralysis, numbness or any kind of weakness in the body.
A TIA can cause sudden dimming of vision, aphasia, mental confusions, or slurred speech. But apart from the stroke, the symptoms TIA could be cleared by 24 hours or within few minutes. While having the TIA the risk factor is attaining a silent stroke. This could be even termed as silent cerebral infarct (SCI). This eventually causes long lasting neurological malfunction which affects the main parts of personality, mood and cognition. This SCI often occurs either after or before TIA or after a major stroke. A cerebral infarct will last for more than 24 hours, but less than those 72 hours is termed as the RIND – reversible neurological deficit.
Signs and symptoms:
This disease symptom varies from person to person, depending upon the size of the brain. This includes the most frequent symptom loss of vision, feeling difficulty while speaking, weaknesses on any of the sides of the body, Loss of consciousness, and temporary and partial paralysis. It also affects the facial region and also the tongue part. The timing for these symptoms is very limited maximum it will lasting for up to 60 mins. There is also possibility of dizziness, due to lack of coordination or weak balance.
The significant cause of TIA is embolus, that blocks up an artery in the brain. This usually arises out of the repositioned atherosclerotic plaque, is known as one of the carotid arteries, or even from thrombus. In TIA the blockage period is very short and hence there is no life-long damage. Some of the problems include excessive narrowing of big vessels resulting out from an atherosclerotic plaque. And it also increases blood viscosity which is caused due to some blood diseases. TIA relates to some of the other medical conditions listed below.
- Hyper tension.
- Cigarette smoking.
- Diabetes mellitus.
- Heart diseases.
- Atrial fibrillation.
The initial treatment is basically aspirin, the second order goes with clopidogrel, and thethird order is that ticlopidine. If ITA is re-occurring then the combination of aspirin and dipyridamole is sufficient and to be given to the patients. An ECG is also necessary. And more over an echocardiogram is useful in counting out the thrombus with in the heart blockages. Such patients take advantages from anticoagulation.
