Bilateral Chorea-Ballism Associated With Non-ketotic Hyperglycemia: A Case Report.

The intricate workings of uncontrolled diabetes and its effects on the nervous system are not fully understood. However, it is known that this condition can lead to various neurological manifestations, including altered consciousness and epileptic seizures. In this case study, a 66-year-old woman presented with abnormal ballistic movements and chorea due to severe hyperglycemia. The results of her brain MRI suggested diabetic striatopathy. Fortunately, her symptoms improved significantly with the normalization of blood glucose levels and appropriate medical intervention. While the exact pathophysiology remains elusive, there is speculation that dysfunction of dopaminergic activity may play a role. The management of these complications involves stabilizing blood glucose levels and providing symptomatic relief. Despite the limited understanding of the underlying mechanisms, these neurological complications generally have a positive prognosis.

Comprehensive Evaluation of Sporadic Late-Onset Cerebellar Ataxias: Clinical Presentation, Diagnostic Challenges, and Treatment Outcomes.

Sporadic late-onset cerebellar ataxias (SLOCA) present a diagnostic challenge due to their heterogeneous etiologies and complex clinical manifestations. This retrospective study aimed to conduct a comprehensive evaluation of six male patients diagnosed with SLOCA, with a mean age of 55 years and an average symptom onset at 47 years. All patients presented with gait and balance disturbances, with additional sensory abnormalities observed in two cases. Neurological examinations revealed varied cerebellar syndromes, including static and static-kinetic presentations, accompanied by peripheral neurogenic syndromes in some instances. Brain MRI findings showed cerebellar atrophy, predominantly involving the vermis, in a subset of patients. Biochemical and serological investigations yielded mostly unremarkable results, although two patients exhibited significant vitamin E deficiency and anti-Hu antibodies (anti-neuronal nuclear antibody type 1). Electromyography confirmed sensory axonal neuropathy in those with peripheral neurogenic syndromes. Treatment with TOCO 500 mg (Vitamin E) was administered to four patients, with follow-up indicating stable disease progression in two cases. This study underscores the complexity of SLOCA and the need for a multidisciplinary approach to diagnosis and management. Further research is warranted to elucidate the underlying mechanisms and improve clinical outcomes for affected individuals.
