Etymology: L, cerebellum, small brain; Gk, ataxia, without order
a loss of muscle coordination caused by a lesion in the cerebellum.

cerebellar ataxia

Neurology A condition characterized by a usually abrupt onset of unsteady gait, nystagmus, and dysarthria, which in children may persist in the form of residual movement or behavioral disorders. See Ataxia.

cerebellar ataxia

MOTOR incoordination due to disease of the CEREBELLUM.


Murri disease
Murri syndrome - cerebellar degeneration. Synonym(s): cerebellar ataxia


failure of muscular coordination; irregularity of muscular action.

cerebellar ataxia
ataxia characterized by defects in rate, range, force and direction of movement of limbs. There is a broad based stance, inability to maintain the head in the proper position so that it oscillates, there is hypermetria or hypometria, direction cannot be maintained and the animal falls easily, often in an exaggerated way.
congenital ataxia
cerebellar ataxia due to viral infection of the fetus, e.g. bovine virus diarrhea and feline panleukopenia, or to inheritance, e.g. in cattle. See also cerebellar atrophy.

hound ataxia
a degenerative myelopathy of Foxhounds, Harrier hounds and Beagles. Affected dogs show increasing hindleg incoordination. A dietary cause is suspected.
locomotor ataxia
tabes dorsalis.
otarid ataxia
a syndrome in pinnipeds caused by nutritional deficiency of thiamin or enterotoxemia or hypoglycemia. Signs include heelwalking (elevation and curling of the rear toes) followed by running staggers, ataxia and violent falling.
progressive ataxia
an inherited disease of cattle in which hind limb ataxia commences at 6 months to 3 years of age and worsens over 1 to 2 more years to the point of recumbency. It is a myelin disorder with eosinophilic plaques in the cerebellar medula and peduncles. Called also progressive sensory ataxia of Charolais cattle.
sensorimotor ataxia
caused by moderate spinal cord lesions, manifested by weakness of movement, scuffing of toes, incomplete limb extension, knuckling, wobbly gait, easy falling, difficult rising.
sensory ataxia
ataxia due to loss of proprioception (joint position sense), resulting in poorly judged movements and becoming aggravated when the eyes are blindfolded.
spinal ataxia
see equine protozoal myeloencephalitis.
vestibular ataxia
a loss of balance with preservation of strength. If unilateral, the abnormality is asymmetrical; if bilateral, it is symmetrical.


pertaining to the cerebellum.

cerebellar abiotrophy
occurs in cattle, pigs and dogs. Affected young are normal at birth but at an early age ataxia and signs of cerebellar dysfunction appear, often progressing to complete immobilization. Cerebral function is usually normal. An inherited basis is suspected. In Kerry blue terriers, it is inherited as an autosomal recessive trait. Called also cerebellar neuronal abiotrophy.
cerebellar agenesis
absence of the cerebellum due to its non-appearance in the embryo.
cerebellar aplasia
see cerebellar atrophy (below).
cerebellar ataxia
the incoordination of gait characterized by exaggerated movements. There is no paresis. There is exaggerated strength and distance of movement—hypermetria. Caused usually by damage to the cerebellum or to the spinocerebellar tracts. May be congenital due to cerebellar atrophy or acquired due to inflammation or malacia of the cerebellum.
cerebellar atrophy
degeneration and loss of cells—Purkinje and granular cells of the cerebellum. Present at birth or soon after, is congenital in sheep, cattle, Arab horses, dogs and cats. Some of the diseases are inherited, some are known to be due to virus infection in utero, e.g. bovine virus diarrhea, feline panleukopenia. Some are in fact abiotrophies, premature aging of tissues. In the latter the animals are normal at birth but develop classical signs later. Segmental atrophy occurs in pigs but is asymptomatic.
cerebellar coning
see cerebellar lipping (below), brain herniation.
cerebellar cortex
the superficial gray matter of the cerebellum.
cerebellar dysfunction
see cerebellar ataxia (above).
cerebellar dysmelinogenesis
recorded in Chow Chow dogs; characterized by congenital head tremor.
feline cerebellar ataxia
see feline panleukopenia.
cerebellar hypomyelinogenesis
abnormally reduced myelination in the cerebellum; characterized clinically by severe neonatal tremor.
cerebellar hypoplasia
deficiency of cells of the cerebellum, the degree and distribution of which is variable. See cerebellar atrophy (above).
inherited cerebellar defects
includes cerebellar abiotrophy, atrophy, agenesis, hypoplasia, neuraxonal dystrophy.
cerebellar lipping
caused by diffuse cerebral edema. The vermis of the cerebellum protrudes through the foramen magnum and lies like a tongue over the medulla.
cerebellar neuronal abiotrophy
see cerebellar abiotrophy (above).
cerebellar neuraxonal dystrophy
reported in collie sheepdogs. The lesion is limited to axons and there are no lesions in the cerebellar folial neurons.
cerebellar syndrome
