A silent lacunar infarction (SLI) is one type of silent stroke which usually shows no identifiable outward symptoms, and is thus termed "silent". Because stroke is a clinical diagnosis (that is, it is defined by clinical symptoms), there is debate about whether SLI are considered to be strokes, even though the pathophysiology is presumably the ...
A brainstem stroke syndrome falls under the broader category of stroke syndromes, or specific symptoms caused by vascular injury to an area of brain (for example, the lacunar syndromes).
Vascular thalamic amnesia occurs when the thalamus is affected by Korsakoff's syndrome or damaged by lacunar infarcts or hemorrhages. [1] Another common cause for damage to the thalamus that may contribute to the development of amnesia is a stroke. [ 2 ]
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

Older age or cognitive impairment at diagnosis, the presence of cerebral infarctions on imaging (stroke), spinal cord involvement, delays in diagnosis and involvement of the medium and large vessels are associated with a poor prognosis and increased mortality in primary CNS vasculitis.
Since stroke is an essential part of vascular dementia, [13] the goal is to prevent new strokes. This is attempted through reduction of stroke risk factors, such as high blood pressure, high blood lipid levels, atrial fibrillation, or diabetes mellitus. [2] [5] Medications for high blood pressure are used to prevent pre-stroke dementia. [19]
Furthermore, "In the microscopic level of small arteries or arterioles, hypertension also generates specific vasculopathies such as lipohyalinosis and thus causing lacunar infarctions". [6] Hypertensions and lacunar infarcts and lacunar stroke are related. This means hypertension is a start to a chain reaction.
And thus it was thought that the pain associated after stroke was part of the stroke and lesion repair process occurring in the brain. [ medical citation needed ] It is now accepted that Dejerine–Roussy syndrome is a condition developed due to lesions interfering with the sensory process, which triggered the start of pharmaceutical and ...
