What is the most common etiology of stroke?

Ischaemic strokes are the most common type of stroke. They happen when a blood clot blocks the flow of blood and oxygen to the brain. These blood clots typically form in areas where the arteries have been narrowed or blocked over time by fatty deposits known as plaques. This process is known as atherosclerosis.

How does meningitis cause stroke?

Approximately 80 percent of all cases are acute bacterial meningitis. Bacterial meningitis can be life threatening. The infection can cause the tissues around the brain to swell. This in turn interferes with blood flow and can result in paralysis or even stroke.

How does inflammation cause a stroke?

Furthermore, accumulation of inflammatory cells, mainly monocytes/macrophages, within the vascular wall starts early during atherogenesis. During later disease stages, their activation can lead to plaque rupture and thrombus formation, increasing stroke risk.

Can listeria cause a stroke?

A small number of patients with Listeria monocytogenes meningoencephalitis have previously been reported to experience stroke-like symptoms that were attributed to microabscess formation and the mass effect of collections of infection in the brain.

Which side is more common for a stroke?

Background and Purpose— Left-sided strokes are reported to be more common than right-sided strokes, but it is unknown whether they occur more often or are simply recognized more easily by clinicians.

What kind of infection can cause a stroke?

Respiratory infection had the highest odds ratio with ischemic stroke in our study. In a prior study, in a 3-day period before a diagnosis of stroke, respiratory infection was associated with stroke, with incidence rate ratio of 3.19 (95% CI, 2.81–3.62).

Can heart inflammation cause a stroke?

Inflammation may promote the growth of plaques, loosen plaque in your arteries and trigger blood clots — the primary cause of heart attacks and strokes.”

Is the etiopathogenesis of stroke a complex trait?

The current article reviews available data related to the etiopathogenesis of stroke, with particular emphasis on the recent achievements on the genetic basis of this complex disease associated with hypertension.

What is the pathophysiology of a stroke?

The pathophysiology of stroke is complex, and involves excitotoxicity mechanisms, inflammatory pathways, oxidative damage, ionic imbalances, apoptosis, angiogenesis and neuroprotection.

Is there a genetic complication of a stroke?

Recent advances in molecular genetics have finally demonstrated what has long been suggested by the clinical observation, that is, stroke is not only the complication of major pathologic conditions such as atherosclerosis, hypertension, or cardiac diseases, but rather it represents a complex trait itself.

Why is stroke considered to be a complex trait?

Both researchers and physicians are now aware that stroke, as well as all cardiovascular diseases, represent complex, multifactorial and polygenic traits, resulting from the complex interactions between the genetic background and several environmental determinants.
