| supranuclear paralysis | Paralysis due to lesions above the primary motor neurons. (05 Mar 2000) |

| progressive supranuclear palsy | A disorder that is associated with nerve cell destruction and progressive lack of coordination, neck stiffness, trunk stiffness, problems with eye movement and mild dementia. Disorders that are similar include Alzheimer's disease, cerebellar dysfunction, Jakob-Creutzfeldt disease and Parkinson's disease. The cause for progressive supranuclear palsy is unknown, but is likely a degenerative nerve disorder that is somehow triggered by a viral infection. Pathologic changes include nerve cell damage and destruction of myelin sheath. There is no known cure. (27 Sep 1997) |
|---|---|
| supranuclear | Above (cranial to) the level of the motor neurons of the spinal or cranial nerves; the pathways the suprasegmental nerve fibres follow to reach the motor cell bodies in the brainstem; as used in clinical neurology, supranuclear indicates disorders of movement caused by destruction or functional impairment of brain structures other than the motor neurons, such as the motor cortex, pyramidal tract, or striate body; e.g., supranuclear palsy, as distinguished from the nuclear (or flaccid, or "lower motor neuron") paralysis that results from destruction or functional impairment of the motor neurons or their axons in a peripheral nerve. (05 Mar 2000) |
| supranuclear lesion | Injury to cerebral descending (corticonuclear) fibres above the brainstem or spinal motor nerve nucleus. Synonym: upper motor neuron lesion. (05 Mar 2000) |
| supranuclear palsy, progressive | A progressive neurological disease usually of the fifth decade characterised by supranuclear ophthalmoplegia especially paralysis of downward gaze, pseudobulbar palsy, gait disturbance, dysathria, truncal dystonia, memory and personality deterioration, and dementia. (12 Dec 1998) |
| acute ascending paralysis | A paralysis of rapid course beginning in the legs and involving progressively the trunk, arms, and neck, ending sometimes in death in from one to three weeks. Synonym: ascending paralysis. (05 Mar 2000) |
| acute atrophic paralysis | Inflammation of the anterior cornua of the spinal cord; an acute infectious disease caused by the poliomyelitis virus and marked by fever, pains, and gastroenteric disturbances, followed by a flaccid paralysis of one or more muscular groups, and later by atrophy. Synonym: acute atrophic paralysis, myogenic paralysis. (05 Mar 2000) |
| ascending paralysis | A paralysis of rapid course beginning in the legs and involving progressively the trunk, arms, and neck, ending sometimes in death in from one to three weeks. Synonym: ascending paralysis. (05 Mar 2000) |
| ascending tick paralysis | <neurology> An ascending paralysis caused by the continued presence of Dermacentor and Ixodes ticks attached to the occipital or upper neck region in humans. The treatment consists of tick removal and supportive care. (27 Sep 1997) |
| Brown-Sequard's paralysis | <neurology, syndrome> A type of spinal cord lesion that is characterised by hemiparaplegia and hyperesthesia, but with loss of motor function on the same side as the lesion and hemianaesthesia on the opposite side. (27 Sep 1997) |
| bulbar paralysis | Progressive weakness and atrophy of the muscles of the tongue, lips, palate, pharynx, and larynx, usually occurring in later life; most often caused by motor neuron disease. Synonym: bulbar palsy, bulbar paralysis, Duchenne's disease, Erb disease, glossolabiolaryngeal paralysis, glossolabiopharyngeal paralysis. (05 Mar 2000) |
| vasomotor paralysis | A mild degree of vasoparalysis. Synonym: angioparesis, vasomotor paralysis. Origin: vaso-+ G. Paresis, weakness (05 Mar 2000) |
| generalised paralysis | Paralysis of both whole sides of the body; survival is usually of short duration. Synonym: generalised paralysis. (05 Mar 2000) |
| paralysis | <neurology> Loss or impairment of motor function in a part due to lesion of the neural or muscular mechanism, also by analogy, impairment of sensory function (sensory paralysis). In addition to the types named below, paralysis is further distinguished as traumatic, syphilitic, toxic, etc., according to its cause or as obturator, ulnar, etc., according to the nerve part or muscle specially affected. Origin: Gr. Lyein = to loosen (18 Nov 1997) |
| paralysis agitans | An obsolete term for parkinsonism. (05 Mar 2000) |
| paralysis, bulbar | A paralysis resulting from changes in the motor centres of the medulla oblongata. It is chronic, usually fatal, and most commonly occurring in persons over 50 years old. (12 Dec 1998) |
