Conclusion: The results suggest that WMH may be an important factor to consider in stroke-related upper extremity motor impairment. Nonetheless, the basis of the largest part of the post-stroke motor deficit remains unaccounted for by structural CNS factors. This component may be behavioral or learned, involving learned nonuse.

Although not specific, an immediate recall deficit was frequently observed in thalamic lesions (OR: 5.2, 95% CI: 1.09-24.9). Centrum semiovale infarcts were less likely to have a potential relevant embolic source (4% versus 11%; odds ratio, 0.16; 95% confidence interval, 0.03–0.83) and caused a lower National Institute of Health Stroke Scale score (2 versus 3; odds ratio, 0.78; 95% confidence interval, … Small stroke: "ischemic infarct centrum semiovale" means a (usually small) stroke high up in the brain that is caused by decreased blood flow (ischemia) to the area The centrum semiovale is the zone of white matter than underlies gray matter on the surface (or cortex) of the brain. This area is nourished by small penetrating arteries, so lacunar infarcts are relatively common here. Lacunar strokes may be entirely asymptomatic, depending on their size and location. The centrum semiovale is a mass of white matter superior to the lateral ventricles and corpus callosum, present in each of the cerebral hemispheres , subjacent to the cerebral cortex. It has a semi-oval shape and contains projection, commissural, and association fibers. Inferolaterally these fibers are continuous with the corona radiata.

Gross anatomy. The parietal lobe accounts for only 19% of the total neocortical volume, only marginally larger than the occipital lobe 3.. The lobe extends from the central sulcus anteriorly, which separates it from the frontal lobe, to the parieto-occipital fissure posteriorly, which separates it from the occipital lobe.

This report constitutes an extremely rare illustration of acute onset organic psychotic depression which was clearly demonstrated to be associated with ischemic stroke. In the present report, we discuss the case of a 66-year-old woman with isolated unilateral hypoglossal paralysis due to cerebral infarction in the centrum semiovale. To date, it has hardly been discussed where the corticolingual tract passes through in the centrum semiovale.
