ABSTRACT
Myoclonic epilepsy, described in 1911 by Lafora and
Glueck, is an autosomal recessive hereditary clinicalpathological
entity, which begins at the end of childhood
or during adolescence, presents atypical absences,
generalized and atonic tonic-clonic seizures, which can
evolve to the epileptic state. The diagnosis is confirmed
trough the skin biopsy or trough determination of
the protein laforine. In this paper we present the initial
case of a patient in whom we confirm the diagnosis
of progressive myoclonic epilepsy and in particular the
Lafora disease, which due to the symptomatology and
the knowledge of the case we were able to detect her
sister’s disease.
Skin biopsies are reported with high sensitivity and
specificity, observing inclusion bodies, and neurophysiological
and electroencephalographic studies are
undoubtedly non-specific. The article reports on the
cases of two sisters, who were definitively confirmed
their diagnosis, which allowed us to focus on the early
detection of the other case.
