A 44-year-old man presented with symptoms of periodic ataxia, dysarthria, nausea and excessive sweating during the last twenty years. These symptoms could be provoked by physical or emotional stress and disappeared after bedrest for several hours. No other members of his family were known to have such complaints. Acetazolamide (Diamox) proved effective in preventing these symptoms. A disturbance of tryptophan metabolism is suggested as a cause of this disorder.

A 19-year-old youth suffered from periodic attacks of ataxia and dysarthria. Abnormally high IgG and IgA levels were found in the CSF. The length of the episodes of ataxia, absence of family history and the presence of generalised paroxysmal features in the EEG constitute a combination which is not believed to have been recorded previously. Carbamazepine was ineffective but temporary clinical and electroencephalographic improvement followed the administration of ACTH. Acetazolamide therapy has resulted in prolonged remissions from attacks.

Acetazolamide responsive hereditary paroxysmal cerebellar ataxia (APCA) is a rare autosomal dominant disorder characterized by attacks of cerebellar ataxia and dysarthria with normal or near normal neurologic function between attacks. A genome-wide search using polymorphic di- and tri-nucleotide repeats was initiated and the APCA locus was found to be linked to the short arm of chromosome 19 in two large kindreds. The microsatellite marker UT705 was found to be linked to the APCA locus with two point analysis yielding a maximum lod score of 8.20 at theta max = 0.000 in a five generation pedigree. Linkage to this region was confirmed in a second kindred. The absence of known candidate genes in the region may necessitate a positional cloning approach in order to identify the gene for this disorder.
