A transient ischemic attack (TIA) can last from a few seconds to a few minutes and is a sign of a stroke that should not be ignored. Dr. Tran Xuan Thuy from the Department of Neurovascular Interventions at Central Military Hospital 108 in Hanoi explains that TIA is a temporary reduction or loss of local cerebral blood supply, leading to localized neurological symptoms that resolve completely within 24 hours. Most TIAs last less than 5 minutes, with an average duration of about one minute.
Due to the temporary nature of TIA symptoms, people often overlook them, but these attacks can progress to more severe strokes. Dr. Thuy warns that about 15% of TIA patients go on to have a stroke within the next 3 months, with half of them experiencing a stroke within 48 hours. It is crucial to recognize TIA symptoms and seek medical attention immediately to prevent a full-blown stroke. Risk factors for TIAs include hypertension, diabetes, smoking, and obesity.
Immediate treatment at a specialized medical facility is vital for TIA patients. Treatment may involve anticoagulation, antiplatelet aggregation, improving cerebral circulation, and controlling blood pressure and fats. Identifying and treating the underlying cause at the hospital can help prevent a stroke. Individuals must control risk factors such as hypertension and diabetes through regular health screenings to avoid future complications.
In conclusion, recognizing the warning signs of transient ischemic attack (TIA) and seeking immediate medical attention can prevent severe strokes in the future. Regular health screenings are essential for individuals who wish to avoid risk factors such as hypertension and diabetes that increase their chances of developing TIAs later on in life.
