What does lacunar infarcts affect?
What does lacunar infarcts affect?
Strokes can damage brain tissue in the outer part of the brain (the cortex) or deeper structures in the brain underneath the cortex. A stroke in a deep area of the brain (for example, a stroke in the thalamus, the basal ganglia or pons) is called a lacunar stroke.
What does lacunar infarcts mean?
Lacunar infarcts are small (2 to 15 mm in diameter) noncortical infarcts caused by occlusion of a single penetrating branch of a large cerebral artery [1,2]. These branches arise at acute angles from the large arteries of the circle of Willis, stem of the middle cerebral artery (MCA), or the basilar artery.
What is lacunar infection?
Lacunar stroke is a type of ischemic stroke that occurs when blood flow to one of the small arteries deep within the brain becomes blocked. According to the National Institutes of Health (NIH) , lacunar strokes represent about one-fifth of all strokes.
Is lacunar infarct a mini stroke?
A quarter of all ischaemic strokes (a fifth of all strokes) are lacunar type. Lacunar infarcts are small infarcts (2–20 mm in diameter) in the deep cerebral white matter, basal ganglia, or pons, presumed to result from the occlusion of a single small perforating artery supplying the subcortical areas of the brain.
Can lacunar infarcts cause seizures?
Background: Lacunar infarcts and white matter changes have been linked to cognitive impairment. Patients with lacunar strokes can also develop seizures, although the relationship between the two remains unclear.
Are lacunar strokes hemorrhagic?
As compared with non-hemorrhagic lacunar stroke, patients with hemorrhagic lacunar stroke were more likely to have hypertension, sudden stroke onset (minutes), head injury, headache, and basal ganglia involvement and less likely to have diabetes, gradual stroke onset (hours), and dysarthria.
What are the four types of seizures?
Epilepsy is a common long-term brain condition. It causes seizures, which are bursts of electricity in the brain. There are four main types of epilepsy: focal, generalized, combination focal and generalized, and unknown. A person’s seizure type determines what kind of epilepsy they have.
