Lafora's disease and brain calcifications.

S Oster¹, E Reske-Nielsen, I Bruun

¹University Department of Neuropathology, Aarhus Kommunehospital, Denmark.

Acta Neuropathologica

|January 1, 1988

Summary

Lafora's disease, a progressive myoclonic epilepsy, involves widespread brain cell inclusion bodies and calcifications. Astrocytes were enlarged but unrelated to these inclusions, suggesting abnormal metabolic product transport.

Background:

Progressive myoclonic epilepsy, specifically Lafora's disease, is a rare and severe neurological disorder.
Understanding the cellular and molecular pathology of Lafora's disease is crucial for developing effective treatments.

Observation:

Examination of a 22-year-old male patient with Lafora's disease revealed widespread inclusion bodies within nerve cells.
Calcifications were observed on both the inner and outer surfaces of the brain.
While no gliosis was present, astrocytes were notably enlarged.

Findings:

Combined staining with glial fibrillary acidic protein (GFAP)-PAS and GFAP-Bodian demonstrated that enlarged astrocytes were not associated with the inclusion bodies.
The neuropathological findings suggest a potential transport mechanism for an abnormal metabolic product contributing to the disease.

Implications:

These findings contribute to the understanding of Lafora's disease pathogenesis.
Identifying the abnormal metabolic product and its transport pathway could offer new therapeutic targets for progressive myoclonic epilepsy.
