Ataxia can be classified according to the onset into episodic, acute, intermittent and chronic ataxia. Acute ataxia in children is caused by CNS tumors, trauma, CNS infection, toxins, metabolic causes or stroke. Recurrent ataxia can be due to metabolic causes, seizures, basilar artery migraine or toxins. Chronic ataxia is usually the result of hereditary ataxia, CNS tumors, congenital anomalies...

BACKGROUND Hereditary ataxias with similar phenotypes were reported in the Smooth-Haired Fox Terrier, the Jack Russell Terrier and the Parson Russell Terrier. However, segregation analyses showed differing inheritance modes in these breeds. Recently, molecular genetic studies on the Russell group of terriers found independent mutations in KCNJ10 and CAPN1, each associated with a specific clinic...

Visual suppression of caloric nystagmus was studied in five patients with hereditary ataxia before and after administration of physostigmine. All patients had an initial abnormal ocular fixation index that improved after physostigmine was given. The data indicate that there is a partly reversible disturbance of visual-vestibular interaction in patients with hereditary ataxia, caused by an impai...

The spectrum of degenerative ataxia includes the symptomatic degenerative ataxias and the primary degenerative ataxias. The later may be sporadic and idiopathic or hereditary, being genetically determined. When an individual ataxic patient presents with an adult-onset degenerative ataxia and has a negative family history, the physician is faced with a diagnosis of pure idiopathic sporadic degen...

T he recent barrage of linkage assignments and gene discoveries has confirmed the clinical and genetic heterogeneity of ataxic diseases. They all share the prototypic feature of difficulty in walking though many additionally present dysarthria, spasticity, retinopathy, and other neurological symptoms. Broad subgroups of ataxias and related diseases exist including spinocerebellar and spastic at...
