5. Transient Ischemic Attacks (TIAs): The Warning Mini-Strokes of CAA
Transient Ischemic Attacks (TIAs), commonly referred to as “mini-strokes,” are another vascular symptom associated with CAA. These occur when there’s a temporary interruption in the blood flow to parts of the brain. Unlike intracerebral hemorrhage, which involves blood escaping from the blood vessels, TIAs involve a brief blockage of blood flow, leading to a temporary reduction in the supply of oxygen and nutrients to the brain.
This temporary disruption can lead to transient neurological symptoms, which resolve completely once the blockage clears and blood flow is restored. TIAs are often seen as a warning sign of a potential future stroke, so it’s critical to take these symptoms seriously and seek immediate medical attention.
The symptoms of a TIA typically last for a few minutes to a couple of hours. This can include temporary weakness or numbness on one side of the body, similar to a stroke. However, these symptoms are temporary and resolve on their own. (5)
