This disease presents no sex-related differences and it is predominantly found in southern European countries. Gradual cerebellar changes; maculopathy with cherry-red spot.

Macular degeneration and visual impairment except in the adult form. In theory, doctors can offer genetic counselling and establish a prenatal diagnosis when the genetic anomaly has been detected in a family member. The disease is caused by a homozygous EPM2 mutation linked to chromosome 6q, which codifies tyrosine phosphatase laforina protein involved in the metabolic control of glycogen.

Psychomotor development and educational level were also normal until the age of Si continua navegando, enffrmedad que ladora su uso. Multiple Lafora bodies in myocytes. Intermittent light stimulation generated a photoparoxysmal response at low frequencies.

During the following 2 years, the patient’s epilepsy progressed unfavourably with increasingly frequent seizures. Previous article Next article. Oligosaccharide deficiency in urine and neuraminidase deficiency in fibroblasts.

He had a healthy brother enfetmedad years older. The patient was finally diagnosed with progressive myoclonus epilepsy based on the above symptoms.

Disease progression was aggressive, with multiple generalised tonic-clonic, myoclonic, and partial seizures accompanied by visual symptoms that persisted in spite of treatment with several drug combinations. Differential diagnosis of progressive myoclonic epilepsies.


He presented bladder and bowel incontinence and tetraparesis, and became confined to bed and armchair. Cranial CT yielded normal results; EEG revealed overall slowing of the background activity plus some diffuse spike-wave complexes.

Myoclonias become continuous during waking hours; they are resistant to antiepileptic medication and usually associated with occipital lobe seizure. The Journal accepts works on basic as well applied research on any field of neurology. From a histological point of view, it is characterised by the presence of intracytoplasmic inclusion bodies in organs such as the liver, heart, and brain.

In conclusion, doctors should assign a suspected diagnosis of Lafora disease when a young patient in late childhood or adolescence begins experiencing myoclonias followed by ataxia and progressive cognitive laflra with no evidence of structural changes in neuroimaging tests and no metabolic changes in the analytical study.


They are characterised by increasingly frequent spike- or polyspike-wave paroxysms. The patient presented truncal ataxia, laforx in both hands that could be increased voluntarily, enfeemedad, and bilateral dysmetria finger-to-nose test. Their parents were not consanguineous, although both were from the same village of some inhabitants.

Are you a health professional able to prescribe or dispense drugs? Paroxysms caused by intermittent light stimulation grow more frequent and gradually become continuous; photoparoxysmal response is typical at low frequencies.

At the age of 12, the patient began to suffer episodes of disorientation lasting a few seconds, which were interpreted as absence seizures. Brain MRI shows no relevant changes in initial and intermediate stages of the disease; final stages are characterised by cerebral and cerebellar atrophy.
