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.

We report a rare case of multiple cranial nerve palsy associated with pregnancy, the cause of which remained to be clarified despite of extensive inspections. A 28-year-old woman with type 1 diabetes on insulin therapy developed left oculomotor nerve palsy in the fourth month of pregnancy. Her symptoms improved after one month's administration of vitamins B1 and B12. Numbness appeared in the left side of the face in the 8th month of pregnancy, and then moved to the right side in two weeks. Dysarthria and dysphagia occurred one month later. Bulbar symptoms were worsened, and she became unable to eat or drink. Neurological examination revealed disturbance of sensation in the right side of the face, soft palate paresis, and bilateral atrophy and fasciculation of the tongue. Extensive laboratory examinations including immunological and endocrinological studies, cerebrospinal fluid examination and brain magnetic resonance imaging were unremarkable. These symptoms remitted spontaneously after delivery, and the methylprednisolone pulse therapy accelerated the improvement. Neurological examination done one year after delivery showed complete recovery of the symptoms except for persistent tongue atrophy.

Progressive signs of ataxia in a eight years old girl prompted neurological investigation. The girl had unstable gait with incoordination of limb movements, impairment of position and vibratory senses, dysarthria, pes cavus, positive Babinski sign and scoliosis. At the age of fourteen the girl was referred in a comatose condition, in a severe diabetic ketoacidosis. Ataxia and hypoactive knee and ankle jerks prompted the analysis of the frataxin gene (FXN; 606829). The most common molecular abnormality: GAA trinucleotide repeat expansion in intron 1 was found with + 300 GAA repeats (1490bp) (normal individuals have 5 to 30 GAA repeat expansions, whereas affected individuals have from 70 to more than 1,000 GAA triplets). Electrocardiogram showed diffuse T wave inversion with sinus bradycardia, while ultrasound revealed concentric, symmetric hypertrophy of left ventricle leading to the diagnosis of hyperthrophic cardiomyopathy. At the age of 14 years, the patient was bound to the wheel-chair, unable to walk. Her brother started to show ataxia at the age of 8 years, and subsequent analysis showed hyperthrophic cardiomyopathy, too. His mutational analysis revealed the same frataxin abnormality, with + 300 GAA repeats. So far, no signs of diabetes occurred. The parents are heterozygous with FXN of 9 -10 GAA (490 bp). Both children received a beta blocker, while the girl's diabetes mellitus was treated by insulin preparations. This is a report of two siblings with Fridreich ataxia and hyperthrophic cardiomyopathy. In addition, the girl developed type 1 diabetes mellitus.

Progressive signs of ataxia in a eight year old girl with hypo-active knee and ankle jerks, prompted the analysis of the frataxin gene (FXN; 606829). The most common molecular abnormality--GAA trinucleotide repeat expansion in intron 1--was found with +300 GAA repeats (1490 bp) (normal individuals have 5 to 30 GAA repeats expansions, whereas affected individuals have from 70 to more than 1000 GAA triplets). Additionally she had unstable gait with incoordination of limb movements, impairment of position and vibratory senses, dysarthria, pes cavus, positive Babinski sign and scoliosis. At the age of fourteen the girl was referred in a comatose condition, in severe diabetic ketoacidosis. Insulin dependent diabetes mellitus was since treated with insulin preparations. Electrocardiogram showed diffuse T wave inversion with sinus bradycardia, while ultrasound revealed concentric, symmetric hypertrophy of the left ventricle leading to the diagnosis of hypertrophic cardiomyopathy. At the age of 14, she is bound to the wheelchair, unable to walk. Her brother started to show ataxia at the age of 8 years and subsequent analysis also showed hypertrophic cardiomyopathy. His mutational analysis revealed the same frataxin abnormality with +300 GAA repeats. So far, no signs of diabetes occurred. The parental DNA was not available for analysis.

Central pontine myelinolysis is characterised by focal osmotic demyelination within the pons. Its clinical presentation varies, but may include acute paralysis, dysarthria and dysphagia. The cause is traditionally associated with overzealous correction of hyponatraemia in patients who are malnourished, alcoholic or chronically ill. However, it may develop in the context of normal serum sodium, since rapid gradient shifts in brainstem osmolalities can occur in other ways. We present an unusual example of central pontine myelinolysis caused by osmotic shifts secondary to hyperglycaemia in a person with type 1 diabetes mellitus and with consistently normal serum sodium concentrations.

Central pontine myelinolysis (CPM) is a demyelinating disorder of central nervous system which involves central portion of the pons and sometimes extrapontine areas also. It is commonly reported in settings of hyponatraemia or its rapid correction, but in the last few years it has also been reported in patients with diabetes in the absence of electrolyte disturbances or correction of serum osmolality. Here we report a case of a 20-year-old female patient, with a known history of type 1 diabetes mellitus, who presented with acute onset spastic quadriparesis with dysarthria and mild ataxia which evolved over 2 weeks. Her MRI brain showed well-defined, bilateral symmetric hyperintense lesion involving central pons showing area of diffusion restriction which was consistent with CPM. Patient was treated conservatively and improved over a period of few weeks. To diagnose more number of cases, we should not overlook CPM in patients with diabetes.

A 24-year-old female who was recently diagnosed with Type 1 diabetes mellitus (TiD) presented with a five-year history of visible gait disturbance and slurred speech. Her neurologic examination was remarkable for dysarthria, bilateral nystagmus, dysdiadochokinesia, finger-nose incoordination, heel-knee incoordination, and ataxic gait. A brain MRI disclosed diffuse cerebellar atrophy. Her serum antiglutamic acid decarboxylase (GAD) antibody titer was elevated. Antinuclear antibody (ANA) test was positive with atiterofl:2560 and a speckledpattern. Genetictests for inherited ataxia, including Friedreich ataxia, were negative for mutations. Her cerebrospinal fluid (CSF) analysis revealed oligoclonal bands and she had a positive CSF GAD65 antibody. A diag- nosis of GAD antibody-induced cerebellar ataxia was considered. She developed GAD autoimmune antibody positive TiD during the course ofher dis- ease. GAD antibody-associated cerebellar ataxia is a rare entity, however it should be considered as a possibility in patients with associated autoimmune disease and positive anti-GAD antibody.
