Popis:	The patients was a 3-year-old boy with psychomotor retardation and attacked by seizures since 8 months of age. On funduscopy, the maculla presented a cherry-red spot. Serum hexosaminidase A activities were as low as 8.2 percent. Both parents were carriers. The patient was diagnosed as classical Tay-Sachs disease by neurological examination. Diphenylhydantoin was continuously given for 2 years and 2 months till his death. Autopsy revealed swelling of the cerebrum, atrophy and sclerosis of the cerebellum, hepatomegaly and mild enlargement of the lymph nodes. Histologically, the cerebrum showed ballooned swelling of nerve cells, slight gliosis and demyelination, while cerebellar Purkinje's cells and granular cells were degenerated and disappeared. The cerebellar cortex showed small focal spongy degeneration. By electron microscopy, membranous cytoplasmic bodies were found in the nerve cells. The change of brain observed in this case were interpreted as a combined result of (i) essential change to classical Tay-Sachs disease, (ii) ischemic change due to frequently repeated seizures, (iii) chronic toxicity by long-term anticonvulsant administration.
