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 ...
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .
The anterolateral central arteries or lenticulostriate arteries [3] (also anterolateral perforating arteries, anterolateral ganglionic arteries, striate arteries, or lateral striate arteries; latin aa. centrales anterolaterales, [4] or aa. lenticulostriatae [4]) are a group of small arteries mostly arising from (the initial M1 part of) the middle cerebral artery that enter the brain through ...
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).
Anatomical overview of the main circuits of the basal ganglia. Subthalamic nucleus is shown in red. Picture shows 2 coronal slices that have been superimposed to include the involved basal ganglia structures. + and - signs at the point of the arrows indicate respectively whether the pathway is excitatory or inhibitory in effect.
The basal ganglia are located bilaterally, and have rostral and caudal divisions. The putamen is located in the rostral division as part of the striatum. The basal ganglia receive input from the cerebral cortex, via the striatum. This is a transverse section of the striatum from a structural MR image.
The caudate nucleus is one of the structures that make up the corpus striatum, which is part of the basal ganglia in the human brain. [1] Although the caudate nucleus has long been associated with motor processes because of its role in Parkinson's disease, [2] [clarification needed] [3] it also plays important roles in nonmotor functions, such as procedural learning, [4] associative learning ...
This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis.
