9. Brief Episodes of Unresponsiveness – A Telling Marker of Small Vessel Disease
Brief episodes of unresponsiveness, also known as ‘transient ischemic attacks’ or ‘mini-strokes’, are another symptom that can point towards the presence of Small Vessel Disease. These episodes are sudden, brief periods during which the individual seems to ‘space out’ or become unresponsive. They might last from a few seconds to a couple of minutes, making them easy to dismiss as a momentary lapse of attention.
These incidents occur when the disrupted blood flow caused by SVD temporarily deprives a part of the brain of oxygen. The manifestation of this symptom can vary widely, depending on which part of the brain is affected.
Some might experience a sudden fall, while others might have difficulty speaking or experience a sudden loss of vision. There might also be instances of sudden confusion or a sudden severe headache.
While these episodes may seem concerning, they are usually harmless and leave no permanent effects. However, they should not be ignored.
These transient episodes are a significant warning sign that the individual is at a high risk of a future stroke. If you or someone around you experiences such episodes, it’s crucial to consult a healthcare professional immediately. (9)
