The authors report on one case of Wolfram syndrome, a rare condition, which is characterized by juvenile onset diabetes mellitus, diabetes insipidus, optic atrophy and sensorineural deafness. The findings of this 13-year follow-up show that this patient developed typical neurological complications of long-standing diabetes mellitus as in the common type 1 variant. Moreover, some peculiar signs occurred such as anosmia, ophthalmoplegia interna, and central nystagmus. Since Wolfram syndrome is probably part of a more generalized neurodegenerative disorder, long-term prognosis will depend both upon the severity of chronic diabetic complications and upon the rapidity, by which degeneration of cerebellar, pontine and brain stem structures appear. Prognosis of the cardinal clinical signs is such that optic atrophy, though usually quite rapid in the beginning, generally does not lead to complete blindness. Sensorineural hearing loss progresses very slowly so that deafness might be expected exceptionally only. The hearing deficit in classical diabetics, however, is of retrocochlear origin. Therefore, in Wolfram syndrome, a combined inner-ear and retrocochlear hearing loss may occur.

Wolfram's syndrome, also known as DIDMOAD syndrome, includes juvenile diabetes mellitus and optic atrophy variously associated with diabetes insipidus and deafness. We describe the neurological findings in 5 patients with Wolfram's syndrome. All patients had a neurological examination and were subjected electrophysiological and brain imaging including CT scan and, in one patient, MRI. There were two pairs of brothers and a sporadic case with paternal consanguinity suggesting recessive inheritance. Neurological abnormalities were found in four patients including dysarthria, seizures, anosmia, nystagmus, ataxia and changes in the electroencephalograms, electroretinograms and evoked potentials. In contrast with previous reports, four patients had abnormal brain CT scan with prominent atrophy of the brainstem. In the patient studied with NMR, severe brainstem and cerebellar atrophy was found. These neuroradiological findings are reminiscent of those described in olivopontocerebellar atrophy and are in agreement with previous pathological studies. We conclude that Wolfram's syndrome includes phenotypical manifestations of olivopontocerebellar atrophy. This reinforces the opinion that olivopontocerebellar atrophy is a nonspecific syndrome of varied causes.
