Know More About Silent Stroke

With the countless number of people who suffer from “stroke” every year, this colloquial term for cerebrovascular accident has become a household word. A stroke or brain attack results from the sudden cut-off of blood supply to certain part of the brain. If blood flow to the brain is cut, even for a few seconds, it can have profound effects on the brain cells, causing hosts of health problems.

Many people think that stroke involves a dramatic turn of events that is accompanies by obvious symptoms, such as weakness or numbness on one side of the body, vision problems, difficulty walking, trouble speaking and loss or changes in consciousness. But the truth is that strokes can happen silently. They can even pass completely unnoticed. While these disruptions in the brain function do not often result in obvious symptoms and require emergency treatment, ‘silent stokes’ can have lasting and significant effects on fragile brain tissues and memory.

Typical stroke vs. silent stroke

During a cerebrovascular accident or typical ischemic stroke, blood supply to a certain part of the brain is cut off. Lack of blood and oxygen supply can cause the area to malfunction and eventually die. The resulting strokesymptoms are often confined to the bodily functions that are controlled by the affected part of the brain. A haemorrhagic stroke results from the bursting of blood vessels to the brain and is usually serious. Both of these types of strokes are accompanied by overt symptoms and require immediate first aid treatment.

On the other hand, a silent stroke often affects blood flow in certain parts of the brain that do not control vital bodily functions. Since this type of stroke causes no obvious symptoms, many people who have had it may not even know they occurred. Although silent strokes do not present any urgent problem, the damages caused are often revealed in diagnostic tests such as MRI and CT scan. These changes in the brain can cause memory problems over time, especially if silent strokes happen frequently.

Repeated episodes of silent strokes can cause more brain damage or injury. So it is important to be proactive when it comes to stroke prevention.
