Pusher syndrome is a clinical disorder following left- or right-sided brain damage, in which patients actively push their weight away from the non-hemiparetic side to the hemiparetic side. This is in contrast to most stroke patients, who typically prefer to bear more weight on their nonhemiparetic side. Pusher syndrome can vary in severity and ...
Brain computer interface (BCI) systems have been proposed as a tool for rehabilitation of monoplegia, specifically in the upper limb after a stroke. [10] BCI systems provide sensory feedback in the brain via functional electrical stimulation, virtual reality environments, or robotic systems, which allows for the use of brain signals. [ 10 ]
Lesions anywhere in the abducens nucleus, cranial nerve VI neurons, or interneurons can affect eye movement towards the side of the lesion. Lesions on both sides of the abducens nucleus can cause a total loss of horizontal eye movement. [6] One other type of gaze palsy is a horizontal saccadic palsy.
Horizontal gaze specifically also involves the Abducens nerve and the Paramedian pontine reticular formation. [2] Horizontal gaze involves synchronous activation of the abducens muscle of one eye and the medial rectus muscle of the other, via communication through the Medial longitudinal fasciculus. Horizontal gaze palsies can be caused by a ...
Pain associated with Dejerine–Roussy syndrome is sometimes coupled with anosognosia or somatoparaphrenia which causes a patient having undergone a right-parietal, or right-sided stroke to deny any paralysis of the left side when indeed there is, or deny the paralyzed limb(s) belong to them. Although debatable, these symptoms are rare and ...
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. It usually subsides completely within 48 hours. Todd's paresis may also affect speech, eye position (gaze), or ...
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.
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.
