Motor neglect concerns all proximal and distal movements, involving both the upper and lower limb in automatic gestures. Taxonomy of motor neglect symptoms is diverse: poor use of the affected limb, difficulty in bimanual activities (such as opening a bottle), spontaneous gestures reduced especially while speaking and, lack of "swing" of the arm while walking.
Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
Patients with hereditary motor and sensory neuropathies are diagnosed through a physical evaluation that looks for muscle atrophy, weakness, and sensory responses. [3] In addition to this, electromyography and motor nerve conduction tests can help clinicians decide what type of motor and sensory neuropathy it is and how severe the disease is.
Output neglect includes motor and pre-motor deficits. A patient with motor neglect does not use a contralesional limb despite the neuromuscular ability to do so. One with pre-motor neglect, or directional hypokinesia, can move unaffected limbs ably in ipsilateral space but have difficulty directing them into contralesional space. Thus a patient ...
Acute motor axonal neuropathy (AMAN) is a variant of Guillain–Barré syndrome. It is characterized by acute paralysis and loss of reflexes without sensory loss. Pathologically , there is motor axonal degeneration with antibody-mediated attacks of motor nerves and nodes of Ranvier .
Four motor symptoms are considered cardinal signs in PD: slowness of movement (bradykinesia), tremor, rigidity, and postural instability. [1] Typical for PD is an initial asymmetric distribution of these symptoms, where in the course of the disease, a gradual progression to bilateral symptoms develops, although some asymmetry usually persists.
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias.. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [2]
Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements. They can result from damage to the motor system. [1]Motor disorders are defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – published in 2013 to replace the fourth text revision – as a new sub-category of neurodevelopmental disorders.
