Deans' stroke musings: Direct Link Between Oral Bacteria and Stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Direct Link Between Oral Bacteria and Stroke

How soon do you think this prevention intervention will be recommended as part of your hospital exit instruction? I'm guessing 50 years, your hospital is not taking responsibility to keep up with current stroke research. Good thing I'm getting my oral problems addressed right now while still treatable. A huge 40 year old filling just fell out, an X-ray revealed the tooth was dead, got it pulled, in 6 months will get an implant.

Researchers at Tampere University have shown for the first time that the cerebral emboli of stroke patients contain DNA from oral pathogens. The research article has been published in the Journal of American Heart Association.

The researchers analysed thrombus aspirates, which neurointerventional radiologists removed from 75 stroke patients as part of emergency treatment. The samples were studied by duplicating bacterial DNA, showing that 79 % of the aspirates contained DNA from bacteria that came from the teeth.

The study is part of a research project at Tampere University, which for ten years has been investigating the effects of bacterial infection in the development of cardiovascular diseases. The research group has previously shown that the same odontogenic bacteria are present in the coronary artery stenoses of patients who have suddenly died, the thrombus aspirates and arterial blood of myocardial infarction patients, ruptured cerebral aneurysms and the thrombus aspirates of patients with lower limb arterial and venous thrombosis.

Cerebral artery thrombosis causes 87 % of strokes. Most thrombi originate in carotid artery stenoses from where they travel to block cerebral circulation.

The results showed that a large amount of DNA from streptococcus viridans – normal bacteria in the mouth – was found in cerebral thrombi compared with normal blood samples from the same patients. In the oral cavity, streptococci are harmless, but when entering circulation, they might cause, among other things, infections of the cardiac valves. The streptococcus bacteria can directly bind to various platelet receptors, making the patient more prone to blood clots.

The research shows that oral health and good dental hygiene are of much greater importance to health than previously known, and that untreated dental infections can cause serious health damage or even death.
