Case Reports[Sensory ganglionopathy as a manifestation of celiac disease].
The neurological manifestations of celiac disease (CD) may be caused by the disease itself, by associated autoimmune diseases or by complications from the tumours that may develop in the long term. We report a case of sensory ganglionopathy associated to CD. ⋯ The neurological manifestations of CD are very varied, but in the presence of a sensory ganglionopathy, a neurological picture that is atypical in this disease, it becomes necessary to suspect SS, which is an infrequent but well established association. Likewise, all patients with SS must be screened for CD, which (albeit subclinically) can be complicated in the long term by the development of tumours. The differential diagnosis of the neurological manifestations of CD and of sensory ganglionopathy, as well as the association between celiac disease and SS, is also discussed.

Review[An update on neurochemistry and pharmacological therapy of the cerebellar ataxias].
To review the available neurochemical data on the different cerebellar ataxias, and the therapeutic trials undertaken in the last twenty-five years. ⋯ A systematic search for treatable ataxias is emphasized, as a response to the severity of the degenerative conditions. The use of GABAergic drugs is proposed in ataxias associated with a deficiency of GABA in the brain, and that of glutamatergic agents, for ataxias associated with glutamate deficiency. The use of serotoninergic and cholinergic drugs is ruled out due to insufficient neurochemical evidence. It is proposed that research on remedies for the cerebellar ataxias should be based on either molecular data, or on neurochemical data, in its defect. To this end, the study of animal or experimental models of ataxia, the use of objective methods for the measurement of ataxia, and the recruitment of homogenous study populations, are all recommended.
