Pusher syndrome is a condition observed in some people following a stroke which has left them with one side weakened due to hemiparesis. Sufferers exhibit a tendency to actively push away from the unweakened side, thus leading to a loss of postural balance. It can be a result of left or right brain damage.
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]
[7] [9] It has been linked to parietal lesions in the left and right hemisphere, stroke and Alzheimer's disease. Initially, researchers tried to isolate the cause to left hemisphere lesions in the parietal lobe because of its similarities to Gerstmann syndrome; however, lesions in the dorsal stream also result in visual agnosia and a piecemeal ...
Apraxia is most often due to a lesion located in the dominant (usually left) hemisphere of the brain, typically in the frontal and parietal lobes. Lesions may be due to stroke, acquired brain injuries, or neurodegenerative diseases such as Alzheimer's disease or other dementias, Parkinson's disease, or Huntington's disease. Also, apraxia ...
The left hemisphere is usually responsible for performing language functions, although left-handed individuals have been shown to perform language functions using either their left or right hemisphere depending on the individual. The anterior frontal lobes of the language-dominant hemisphere are essential for initiating and maintaining speech. [1]
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]
The condition is usually due to an insult to the dominant hemisphere of the brain. More often this is located in the frontal lobe of the left hemisphere of the brain. Treatment of acquired apraxia due to stroke usually consists of physical, occupational, and speech therapy.
The outlook for someone with lateral medullary syndrome depends upon the size and location of the area of the brain stem damaged by the stroke. [2] Some individuals may see a decrease in their symptoms within weeks or months, while others may be left with significant neurological disabilities for years after the initial symptoms appear. [4]
