Is your doctor taking responsibility to make sure you know EXACTLY what needs to be done to keep this oral bacteria at bay? Did you get recovered enough to brush your teeth with your affected hand? That is the definition of recovery you should expect.
Stroke Study Finds Mouth Bacteria In Brain Clots
Researchers from Tampere University in Finland analyzed clot samples from 75 people who received emergency treatment for ischemic stroke when they attended Tampere University Hospital's Acute Stroke Unit
These procedures remove blood clots by means of catheters conducted through arteries. The catheters can deploy stent retrievers and aspirators to reduce or remove the clot.When they analyzed blood clots sampled in this way, the researchers found that 79% of them bore DNA from common oral bacteria.
Most of the bacteria were of the Streptococcus mitis type, which belong to a group that scientists call viridans streptococci.The levels of the oral bacteria were much higher in the blood clot samples than they were in other samples that surgeons took from the same patients.
The team reports the findings in a recent Journal of the American Heart Association study.The study forms part of a large investigation that Tampere University has been conducting for around 10 years on the role of bacteria in cardiovascular diseases.This investigation has already found that blood clots that have caused heart attacks, brain aneurysms, and thromboses in leg veins and arteries, contain oral bacteria, particularly viridans streptococci.
This starves cells of essential oxygen and nutrients and can result in tissue damage and loss of function in the brain.The most common type of stroke is an ischemic stroke, which occurs when a blood clot reduces the blood supply in an artery that feeds the brain.According to figures from the World Stroke Organization, around 1 in 6 people worldwide will likely experience a stroke in their lifetime.One of the leading causes of stroke is a condition called atherosclerosis in which plaques form in the walls of arteries and cause them to narrow and harden over time.
The plaques are deposits of cellular waste, fat, cholesterol, and other materials.Depending on where the plaques form, atherosclerosis can raise the risk of heart disease, angina, carotid artery disease, and peripheral artery disease.However, plaques can also lose bits into the bloodstream, or attract clots.
If such an event affects an artery supplying blood to the brain, it can trigger an ischemic stroke
