23 Jul Does a Mini Stroke Cause Dementia?
Are you aware that stroke is one of the leading causes of disability and death? Over 59% of strokes occur in the older generation, whereas 38% of strokes happen in middle-aged adults. While the occurrence of stroke has increased in the past couple of years, the level of awareness about it is still at an all-time low. If you notice any of these signs, then don’t hesitate to visit the hospital.
- When your smile becomes sloppy or your face has fallen to one side
- If you’re unable to raise both your hands and keep them there for a while
- If your speech is unclear and slurred
These instances are enough to let you know that you’re having a stroke and it needs to be treated. But can a mini-stroke cause dementia? Before we delve deeper, let’s understand everything there is to learn about a stroke.
Different Types of Stroke
- Ischemic stroke: This type of stroke usually happens when a blood vessel is blocked due to a blood clot
- Hemorrhagic stroke: When the blood flow to the brain is interrupted and causes a blood vessel to burst, it leads to hemorrhagic stroke
- Mini stroke: Sometimes, the blood flow may be interrupted for a short time and it’s known as a Transient Ischemic Attack (TIA) or mini-stroke
- More often, Ischemic strokes and TIA or mini-stroke are associated with vascular dementia. Vascular dementia is said to be the second common form of dementia
Does a stroke increase the risk of vascular dementia?
According to a study conducted in the year 2012, it was revealed that 9 of the people who’re suffering from dementia have suffered a stroke in the past. Vascular dementia can often result in forgetting information. While vascular dementia can be a post-stroke condition, it’s important to remember that it’s not necessary that whoever has had a stroke is at risk of developing vascular dementia.
Research claims that senior citizens over the age of 65 have a high risk of developing a stroke and getting a high risk of dementia that’s completely unrelated to a stroke. The results from several studies claim that 10% of individuals who have suffered a stroke will develop dementia within the first year of getting a stroke.
But it’s said that stroke is a risk factor for dementia and dementia can be caused due to a severe stroke.
Since it’s difficult to diagnose a stroke, it’s important to consult your doctor. But vascular dementia is a condition that can worsen over time. Hence, it’s advisable to conduct a CT scan, MRI scan, or brain imaging test, and let your doctor look for some abnormalities.
