[21] The left hemisphere is often involved with dealing of detail-oriented perception while the right hemisphere deals mostly with wholeness or an ...
Pure motor stroke/hemiparesis (most common lacunar syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct.
Emotional lability occurs in about 20% of those who have had stroke. Those with a right hemisphere stroke are more likely to have empathy problems which can make communication harder. [234] Cognitive deficits resulting from stroke include perceptual disorders, aphasia, [235] dementia, [236] [237] and problems with attention [238] and memory. [239]
Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere. It is classically considered a left-hemisphere disorder, although right-hemisphere damage has also been associated with components of the syndrome. [2] It is named after Jewish Austrian-born American neurologist Josef Gerstmann. [3]
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]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Other symptoms include hoarseness, nausea, vomiting, a decrease in sweating, problems with body temperature sensation, dizziness, difficulty walking, and difficulty maintaining balance. Lateral medullary syndrome can also cause bradycardia , a slow heart rate, and increases or decreases in the patient's average blood pressure.

In 5 of these patients, the deficit was restricted to the body of other persons (pure heterotopagnosia), while for the 4 other patients, the inability to point at external targets included both other ...
