Researchers Find Oral Bacteria Presence in Cerebral Emboli of Stroke Patients

Scientists at Tampere University analyzed the cerebral emboli (blood clots) of stroke patients’ brains and made an astonishing discovery. For the first time, they discovered DNA from oral pathogens in the cerebral clots.

The findings of the research were published in the May 2019 issue of the prestigious Journal of American Heart Association, reported Science Daily.

When stroke patients came into Emergency Rooms for treatment, neurointerventional radiologists removed the pesky clots known as thrombus aspirates from 75 of these stroke patients. The thrombus aspirates samples were analyzed by the scientists who discovered that 79% of the aspirates contained oral bacterial DNA in them. The samples were analyzed following the duplication of the bacterial DNA.

Tampere University is involved in the study of the consequences of bacterial infection in the development of cardiovascular diseases over the past ten years. Their study is a part of this research project. An older study discovered the same odontogenic bacteria in the coronary artery stenoses of patients who seemed to have suddenly died.

These bacteria were also present in samples taken from:

  • Blood clot blockages and arterial blood of myocardial infarction patients
  • Ruptured weak cerebral blood vessels and blood clot blockages of patients with lower limb arterial and venous thrombosis

Most of these blood clots (thrombi) originate in the carotid artery stenoses of the circulatory system. As blood circulates all the time, the clots break off and travel to block circulation in delicate cerebral arteries. In fact, 87 % of the strokes are caused due to cerebral artery thrombosis.

The new study has discovered a copious amount of viridans streptococcus DNA in cerebral thrombi when compared against normal blood samples taken from the same patient. Viridans Streptococcus is a commonly found oral bacteria. It is completely harmless when present in the oral cavity. However, when streptococci enter the circulatory system, they may cause infection in the cardiac valves, among other things. The bacterium also tends to directly bind with various platelet receptors, thereby enabling more blood clots to form in the bloodstream.

If this research doesn’t encourage you to maintain your oral health and practice good dental hygiene, nothing else will. Untreated dental infections can have a severe effect on your overall health and even cause loss of life. Get your dental problems addressed as soon as possible to lead a healthier and longer life.

The Importance of Early Diagnosis in Parkinson’s Disease

Receiving a diagnosis for a progressive neurological condition can feel daunting for any individual and their family. When initial symptoms appear, it is natural to feel uncertain about what they mean. Yet, seeking clarity through an early diagnosis of Parkinson’s disease can be an empowering first step. It opens up pathways to support, treatment, and proactive planning that can significantly improve a person’s quality of life for years to come.

Recognising the Early Signs

Parkinson’s is often associated with motor symptoms like tremors, stiffness, and slow movement. These are certainly defining features of the condition, but they are not always the first to appear. In many cases, subtle, non-motor symptoms can precede the more obvious signs. Recognising these can prompt a conversation with a GP sooner.

Some of these early indicators might include:

  • A reduced sense of smell that is not related to a cold or allergies.
  • Persistent sleep problems, such as acting out dreams while asleep.
  • Small, cramped handwriting, known as micrographia.
  • A softer or more monotone voice.
  • Constipation that becomes a chronic issue.
  • A feeling of stiffness in the body or limbs.

These symptoms can be caused by many other things, but if they persist, it is worth discussing them with a healthcare professional. They can build a picture of your overall health and decide if a referral to a specialist is needed.

The Benefits of Seeking a Diagnosis

An early and accurate diagnosis provides a clear foundation for managing the condition. It removes the uncertainty that comes with unexplained symptoms and allows individuals and their families to move forward with a plan. One of the most immediate benefits is access to therapies and medications that can help manage symptoms effectively. While there is no cure for Parkinson’s, treatments can help control movement difficulties and improve daily function.

Beyond medical treatment, a diagnosis allows for proactive lifestyle adjustments. This could involve working with a physiotherapist to improve balance and flexibility or seeing an occupational therapist to find new ways of performing daily tasks. It also provides the time to make important decisions about the future, from financial planning to home modifications, without the pressure of a crisis.

A Practical Scenario

Consider a man in his late sixties who starts to notice a slight tremor in his hand when he is resting. His wife also observes that he no longer swings his right arm when they go for walks. Initially, he dismisses it as a sign of getting older. After some encouragement, he visits his GP. Following a referral to a neurologist and a thorough clinical evaluation, he receives a diagnosis of early-stage Parkinson’s disease.

Because the diagnosis came early, he was able to start a medication regimen that helped control his tremor. He also began regular sessions with a physiotherapist to work on his gait and balance. This proactive approach allowed him to continue his hobbies, stay active, and maintain his independence at home. His family had time to learn about the condition and identify what support they might need in the future, which reduced their collective anxiety.

Planning for Future Support

An early diagnosis is not just a medical label; it is a tool for empowerment. It allows a person to take an active part in their own care, making informed choices about their health and wellbeing. It also helps families prepare for the road ahead, ensuring that a strong support network is in place. Knowing what to expect makes it easier to adapt to changes as they happen.

Building a comprehensive support system is a key part of managing a long-term condition. This includes medical professionals, community groups, and practical help at home. Many families find that professional support provides essential respite and tailored assistance. Accessing specialist Parkinson’s homecare ensures that care can adapt as an individual’s needs evolve, promoting comfort and independence in a familiar environment.
