Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
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.
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
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.
Central facial palsy is often characterized by either hemiparalysis or hemiparesis of the contralateral muscles in facial expression. [2] Muscles on the forehead are left intact. Also, most patients have lost voluntary control of muscle movement in the face—however, muscles in the face involved in spontaneous emotional expression often remain ...
Contralateral brain. The contralateral organization of the forebrain (Latin: contra‚ against; latus‚ side; lateral‚ sided) is the property that the hemispheres of the cerebrum and the thalamus represent mainly the contralateral side of the body. Consequently, the left side of the forebrain mostly represents the right side of the body, and ...
Thus, if you have a right hemisphere trans-tentorial herniation, it causes a Kernohan's notch in the left cerebral peduncle which results in right-sided motor impairment. Therefore, you get, paradoxically, impairment of motor function on the same side of the body as the herniation which caused the Kernohan's notch on the contralateral side. [3]
Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system.Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.
