Hemispatial neglect results most commonly from strokes and brain unilateral injury to the right cerebral hemisphere, with rates in the critical stage of up to 80% causing visual neglect of the left-hand side of space. Neglect is often produced by massive strokes in the middle cerebral artery region and is variegated, so that most sufferers do ...
The second, the ipsilateral pathway, allows for the transmission of information along the same side of the body (i.e., the left side of the body to the left hemisphere). [ 15 ] In a healthy individual, when a hand is stimulated by touch, there is increased brain activity in the contralateral hemisphere, and decreased activity in the ipsilateral ...
This forces the patient to exercise spatial awareness using the damaged side of the brain, increasing activity around the lesion. While generally a treatment used for visual neglect (a different but related neurological disorder), LLA still increases brain activity around damaged area in patients with visual extinction and generates improvement ...
Prism adaptation can be used to rehabilitate the visuo-spatial deficits of neurological disorders such as unilateral neglect.It has become clear that with respect to being used as a long-term rehabilitative tool, prism adaptation is only effective when it is repeated over many sessions and with sufficiently strong prism goggles (Newport and Schenk, 2012).
Motor imagery is a process by which a specific action is mimicked in the working memory without a corresponding motor output. Since constructional apraxia is a visuospatial problem not a motor problem, rehabilitation-treatment based on motor imagery has not proven to be an effective in patients with right hemisphere stroke or hemispatial neglect.
Injury to the right side of the brain will affect the left visual fields of each eye. The more posterior the cerebral lesion, the more symmetric (congruous) the homonymous hemianopsia will be. For example, a person who has a lesion of the right optic tract will no longer see objects on his left side.

Treatment for hemiparesis is the same treatment given to those recovering from strokes or brain injuries. [1] Health care professionals such as physical therapists and occupational therapists play a large role in assisting these patients in their recovery. Treatment is focused on improving sensation and motor abilities, allowing the patient to ...
