Hemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (hemi-means "half"). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body.
For example, in a gap detection test, subjects with egocentric hemispatial neglect on the right side often make errors on the far right side of the page, as they are neglecting the space in their right visual field. [21] The next range of neglect is "allocentric" neglect, where individuals neglect either their peri-personal or extrapersonal space.
A frequently occurring motor deficit is left-sided hemiparesis (in strokes affecting the motor cortex). A less common motor deficit in this population is dysphagia. [4] Patients with right hemisphere brain damage often display sensory deficits such as left neglect, in which they ignore everything in the left visual field. [5]
Hemiparesis – The loss of function to only one side of the body; Triparesis – Three limbs. This can either mean both legs and one arm, both arms and a leg, or a combination of one arm, one leg, and face; Double hemiparesis – All four limbs are involved, but one side of the body is more affected than the other; Tetraparesis – All four limbs
Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
Superior alternating hemiplegia (also known as Weber syndrome) has a few distinct symptoms: contralateral hemiparesis of limb and facial muscle accompanied by weakness in one or more muscles that control eye movement on the same side. [2] Another symptom that appears is the loss of eye movement due to damage to the oculomotor nerve fibers.
Todd's paresis (or postictal paresis/paralysis, "after seizure") is focal weakness in a part or all of the body after a seizure.This weakness typically affects the limbs and is localized to either the left or right side of the body.
