    Abstract:
    We present two siblings with hereditary cortical cerebellar atrophy (CCA), who showed peculiar clinical features. Their unaffected parents are cousins. The mode of inheritance in this family was autosomal recessive. Both patients developed involuntary movement and ataxia during the fourth decade. The proband (patient 1) was the elder sister. She developed choreoathetoid involuntary movement and cerebellar ataxia at the age of 32. At the age of 39, she showed mental deterioration and marked gait disturbance due to severe ataxia and amyotrophy. At the age of 40, she took medication for hypertension. At the age of 42, she was bedridden and had generalized convulsions and dysautonomia. Involuntary movement continued until her death at age 44. She had amenorrhea since the age of 25 years. Neuropathological findings. The brain weighed 1,010 g. We found marked degeneration in the cerebellar cortex including the molecular, Purkinje cells, and granular cell layers, and in the inferior olivary nuclei. In the basal ganglia, the putamen and caudate nuclei were moderately affected, but the substantia nigra and globus pallidus were spared. The cerebral cortex was spared, but the cerebral white matter showed diffuse myelin pallor without fibrillary gliosis. In the pons, the volume of the tegmentum was moderately decreased, but the base was spared. The spinal cord was normal. The findings of the patient differed from those of the case originally reported by Gordon Holmes in 1907. Holmes autopsied a case showing severe degeneration in both the cerebellar cortex including all three layers and the inferior olivary nucleus as in our patient. However, the striatum of his case spared and the patient did not develop involuntary movement as did other patients. The patients presented here should be distinguished from Holmes' original case clinicopathologically.(ABSTRACT TRUNCATED AT 250 WORDS)
