Total 19 clinical symptoms reported for Spinocerebellar ataxia type 6
Bradyopsia |
Difficulty in seeing moving objects.
Synonyms:Difficulty seeing moving objects |
Very frequent |
Gait ataxia |
A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.
Synonyms:Ataxia of gait; Ataxic gait; Inability to coordinate movements when walking |
Very frequent |
Gaze-evoked horizontal nystagmus |
Horizontal nystagmus made apparent by looking to the right or to the left.
Synonyms:Nystagmus, horizontal, gaze-evoked |
Very frequent |
Incoordination |
Synonyms:Difficulties in coordination; Incoordination; Incoordination of limb movements; Limb incoordination |
Very frequent |
Intention tremor |
A type of kinetic tremor that occurs during target directed movement is called intention tremor. That is, an oscillatory cerebellar ataxia that tends to be absent when the limbs are inactive and during the first part of voluntary movement but worsening as the movement continues and greater precision is required (e.g., in touching a target such as the patient's nose or a physician's finger).

Nystagmus |
Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms.
Synonyms:Involuntary, rapid, rhythmic eye movements |
Very frequent |
Postural instability |
A tendency to fall or the inability to keep oneself from falling; imbalance. The retropulsion test is widely regarded as the gold standard to evaluate postural instability, Use of the retropulsion test includes a rapid balance perturbation in the backward direction, and the number of balance correcting steps (or total absence thereof) is used to rate the degree of postural instability. Healthy subjects correct such perturbations with either one or two large steps, or without taking any steps, hinging rapidly at the hips while swinging the arms forward as a counterweight. In patients with balance impairment, balance correcting steps are often too small, forcing patients to take more than two steps. Taking three or more steps is generally considered to be abnormal, and taking more than five steps is regarded as being clearly abnormal. Markedly affected patients continue to step backward without ever regaining their balance and must be caught by the examiner (this would be called true retropulsion). Even more severely affected patients fail to correct entirely, and fall backward like a pushed toy soldier, without taking any corrective steps.
