Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures.
Hypertensions and lacunar infarcts and lacunar stroke are related. This means hypertension is a start to a chain reaction. From lipohyalinosis to lacunar infarctions that may eventually lead to stroke, hypertension, uncontrolled, can cause a lot of damage to the brain. [citation needed]
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
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).
Blockage of the lenticulostriate arteries causes lacunar strokes. These infarcts are most often due to hyaline arteriosclerosis secondary to hypertension . This can lead to contralateral paresis (muscular weakness) and/or sensory loss of the face and body.
Based on the extent of the symptoms, the stroke episode is classified as total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), lacunar infarct (LACI) or posterior circulation infarct (POCI). These four entities predict the extent of the stroke, the area of the brain affected, the underlying cause, and the ...
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

CT scan of two lacunar infarctions. Moments after an ischemic stroke, lesions are established that can be detected. Hypertension is the leading cause of strokes and studies show that it increases the risk of a stroke by 220% [17] [18] and stroke is the leading cause of long-term disability. [19]
