| vestibulocerebellar ataxia | Ataxia due to disease of the central vestibular system or its cerebellar components, manifested clinically by an unsteady gait, nystagmus, and incoordination of arm and leg movements. (05 Mar 2000) |
|---|---|
| respiratory ataxia | Completely irregular breathing pattern, with continually variable rate and depth of breathing; results from lesions in the respiratory centres in the brainstem, extending from the dorsomedial medulla caudally to the obex. Synonym: ataxic breathing, Biot's breathing, respiratory ataxia. (05 Mar 2000) |
| chronic ataxia | Persistent ataxia, most often caused by hereditary cerebellar or metabolic disorders. (05 Mar 2000) |
| moral ataxia | Inconstancy of ideas and of conscious intent, as a manifestation of hysteria. (05 Mar 2000) |
| motor ataxia | Ataxia developing upon attempting to perform coordinated muscular movements. Synonym: kinetic ataxia. (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) |
| kinetic ataxia | Ataxia developing upon attempting to perform coordinated muscular movements. Synonym: kinetic ataxia. (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) |
