Symptoms of cerebellar abiotrophy include ataxia or lack of balance, an awkward wide-legged stance, a head tremor (intention tremor) (in dogs, body tremors also occur), hyperreactivity, lack of menace reflex, stiff or high-stepping gait, coarse or jerky head bob when in motion (or, in very young animals, when attempting to nurse), apparent lack ...
Rarely, horses will show a spastic gait in the front limbs in which the leg is held in full extension or with the knee flexed, with trembling occurring in the upper limb. [2] Despite histologic changes in the cerebellum, horses with shivers do not show clinical signs typical of cerebellar disease (ataxia, intention tremors). [3]
Common signs of dyschronometria are often generic to cerebellar ataxia, including a lack of spatial awareness, poor short term memory, and inability to keep track of time. [citation needed] [5] The defining symptoms, while not completely understood, involve time perception. For example, when asked to wait for thirty seconds, or tap every second ...
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.
An equine behaviourist said warning signs included ‘pinned ears, tense facial muscles, swishing tails or shifting weight’. An equine behaviourist said warning signs included ‘pinned ears ...
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 ]
Cerebellar signs usually involve balance and coordination, and may include: [citation needed] cerebellar ataxia a gait with a broad base; the patient falters to the side of the lesion ( ataxia ) inability to coordinate fine motor activities ( intention tremor ), e.g. "past-pointing" (pointing beyond the finger in the finger-nose test)
Cerebellar abiotrophy: a rare genetic disorder that occurs in Arabian horses, producing ataxia, a base-wide stance, proprioceptive deficits, and high-stepping gait. Damage to individual nerves will affect the muscles they innervate and subsequently alter gait.
