| hereditary spinal ataxia | Sclerosis of the posterior and lateral columns of the spinal cord, occurring in children and marked by ataxia in the lower extremities, extending to the upper, followed by paralysis and contractures; autosomal recessive inheritance. See: spinocerebellar ataxia. Synonym: Friedreich's ataxia, heredotaxia. (05 Mar 2000) |
|---|---|
| sensory ataxia | An ataxia due to impairment of position sense caused by lesions located at some point along the central or peripheral sensory pathways. (05 Mar 2000) |
| hysterical ataxia | Weakening of the muscle sense and increased sensibility of the skin, in hysteria. Synonym: hysterical ataxia. (05 Mar 2000) |
| spinal ataxia | Ataxia due to spinal cord disease, as in tabes dorsalis. (05 Mar 2000) |
| spinocerebellar ataxia | The most common hereditary ataxia, with onset in middle to late childhood, manifested as limb ataxia, nystagmus, kyphoscoliosis, and pes cavus; the major pathological changes are found in the posterior columns of the spinal cord; most often autosomal recessive inheritance. (05 Mar 2000) |
| static ataxia | Inability to preserve equilibrium while standing, due to loss of myesthesia; present during the resting state. (05 Mar 2000) |
| optic ataxia | An inability to guide the hand toward an object using visual information; seen in Balint's syndrome. (05 Mar 2000) |
| enzootic ataxia | A metabolic disease of lambs characterised clinically by progressive incoordination of the hind limbs and pathologically by disruption of neuron and myelin development in the central nervous system; caused by a deficiency of metabolizable copper in the ewe during the last half of her pregnancy. Synonym: swayback. (05 Mar 2000) |
| equine spinal ataxia | A disease of young horses characterised by progressive weakness and incoordination, most evident in the hind legs; it is associated with lesions in the cervical region of the spinal cord and is the result of compression of the spinal cord by malformed cervical vertebrae. (05 Mar 2000) |
| Friedreich's ataxia | <neurology> An autosomal recessive inherited disorder that leads to the progressive dysfunction of the cerebellum, spinal cord and peripheral nerves. Symptoms usually begin in childhood before puberty and consist of an unsteady gait (ataxia), slurred speech (dysarthria) and jerky eye movements (nystagmus). Other findings include kyphoscoliosis, hammer toe, heart disease and high arches. Congestive heart failure is a common complication. There is no known treatment and prognosis is poor. Inheritance: autosomal recessive. (07 Apr 1998) |
| Leyden's ataxia | A syndrome having the characteristics of tabetic neurosyphilis but not due to syphilis. Synonym: Leyden's ataxia, peripheral tabes, pseudoataxia. (05 Mar 2000) |
| locomotor ataxia | The severe gait ataxia seen with tabetic neurosyphylis. Patients walk with the feet wide apart, slapping them clumsily to the floor with each step, and depend on visual cues to maintain balance. See: tabetic neurosyphilis. (05 Mar 2000) |
