A mild stroke caused by a brief stoppage of blood supply to the brain.
A brief disruption of blood flow to a section of the brain leads to temporary dysfunction in vision, speech, sensation, or movement. These occurrences, known as Transient Ischemic Attacks (TIAs), usually endure for a few minutes or, in more extended instances, a few hours. TIAs are occasionally referred to as “mini-strokes” and can serve as a precursor to a full-blown stroke. Within five years, a stroke may occur in as many as one-third of patients who have experienced a TIA.
Transient Ischemic Attacks (TIAs) can result from a temporary blockage of an artery that supplies the brain, often due to a blood clot, or from artery constriction due to atherosclerosis, characterized by the accumulation of fatty deposits within the artery walls.
Following a transient ischemic attack (TIA), it may be necessary to conduct various tests including CT scans, blood tests, and procedures like angiography or Doppler ultrasound scans of the carotid artery in the neck. These tests aim to identify the underlying cause. Additionally, in certain instances, an examination of the heart might be undertaken to explore the potential origin of blood clots.
The treatment strategy to prevent a stroke encompasses procedures like endarterectomy, where the inner lining of an artery affected by atherosclerosis is surgically removed. Additionally, the use of aspirin to reduce blood “stickiness” and anticoagulant medications are also employed. Individuals who have experienced a TIA can take steps to minimize their stroke risk through lifestyle adjustments, including quitting smoking and adopting a low-fat diet.
