What is a Pre-Stroke?
A pre-stroke, also known as transient ischemic attacks (TIA), occurs when there is a brief lack of blood flow to the brain. The manifestation is similar to that of a stroke, but it disappears within 24 hours, leaving no permanent disabilities.
A transient ischemic attack happens when a blood clot cuts the blood flow in one part of the brain either fully or partially. Unlike a stroke, where the clot is permanent and can cause severe damages, the symptoms of TIA fade as soon as the blood flow is resumed.
Signs You May be Having a Pre-Stroke
A pre-stroke can cause dizziness, confusion, and blurry vision. In some cases, patients might even experience paralysis on one side of the body or have problems with their balance. People with a TIA may temporarily find themselves unable to speak. Other speech problems may include trouble saying a word or trouble understanding words.
Another indication of a TIA is weakness or numbness on just one side of the body or face, determined by the location of the blood clot in the brain
What to Do in Case of a Pre-Stroke
These symptoms are all indicative of potential damage to the brain tissue. While pre-stroke symptoms fade within 24 hours, it is very hard to distinguish between a stroke and a TIA.
If you or someone you know is showing any of these signs or all of them, the best thing to do is to call an ambulance and take them to a facility that provides emergency care in Bulverde. Do not try to drive yourself or the person who might be suffering from a pre-stroke to the emergency room. Paramedics are trained to offer preliminary assistance on-site to stabilize the patient and then take them to the emergency room.
The signs of a pre-stroke and stroke are very similar, but only a medical professional can diagnose them accurately. Pre-strokes do not leave permanent damage to the brain but they should be checked by an expert medical team, such as ours at Physicians Premier. We have capable, board-certified doctors who can exclude a stroke diagnosis and offer further suggestions to prevent another TIA episode.
