In addition, in this case, we reported a special case of LINCL as one form of the most fatal PME, to present some special EEG characteristics in details. [journals.lww.com]

The accumulation (storage) of these metabolites occurs because an essential enzyme, needed to further metabolize the accumulated chemicals, is not present or is present in insufficient concentration. [rarediseases.org]

• Wheelchair Bound

  Ataxia and myoclonus are progressive with patients becoming wheelchair bound in their early teens. Many EPM6 patients have scoliosis or other skeletal abnormalities. [preventiongenetics.com]

  The disease course showed a relentless decline; patients uniformly became wheelchair bound (mean age 13 years) and four had died during their third or early fourth decade. [academic.oup.com]

  Neurological examination is initially normal, but patients later develop intention tremor, dysarthria, ataxia and poor coordination, thus subsequently one-third of EPM1 patients become severely incapacitated and wheelchair bound. [journals.plos.org]

• Generalized Tonic-Clonic Seizure

  […] for about 12 to 14 years in both patients, not only for myoclonus but generalized tonic-clonic seizures as well. [statpearls.com]

  Symptoms like stimulus induced myoclonic jerks, cognitive decline and motor slowing, generalized tonic-clonic seizures, or visual/occipital seizures help narrow the diagnosis. [epilepsy.com]

  Generalized tonic clonic seizures were documented in all except Patient 2. The average age of onset of generalized tonic clonic seizures was 13.3 years (range 3–24 years; Table 1). [academic.oup.com]

• Drop Attacks

  Myoclonic seizures begin in early childhood, and patients exhibit multiple seizure types including: generalized tonic clonic seizures, absence seizures, and drop attacks. [preventiongenetics.com]

  Patients 1, 2, 4 and 7 had drop attacks beginning around the age of 13 or 14 years. Generalized tonic clonic seizures were documented in all except Patient 2. [academic.oup.com]

   Characteristically, visual seizures are the first manifestation, followed by generalized tonic–clonic seizures, absences, or drop attacks.  Visual seizures present as transient blindness, simple or complex visual hallucinations.  Myoclonus is often [slideshare.net]

DIAGNOSTIC WORKUP In the initial stage of Ohtahara syndrome, interictal EEG shows a pattern of suppression-burst with high-voltage paroxysmal discharges separated by prolonged periods of nearly flat tracing that last for up to 18 seconds. [europeana.eu]

• Generalized Epileptiform Discharges

  EEG shows slow dysrhythmia, multifocal and occasionally generalized epileptiform discharges. [genecards.org]

So far, the treatment of PMEs remains symptomatic (i.e. pharmacological treatment of myoclonus and seizures), since there is no etiologic treatment for most PMEs. Pharmacological treatment of PMEs usually relies on a combination of ≥ 2 AEDs [2]. [ncbi.nlm.nih.gov]

Treatment-emergent adverse events affecting >10% of patients in the pivotal studies were dizziness, headache and somnolence. [ots.at]

However, the female patient has a poor prognosis. In the following visit, she has serious sleep problems, such as sleep fragment and insomnia due to her sensitivity to the light and voice. [journals.lww.com]

PROGNOSIS AND THREATMENT Half of the reported children having Ohtahara syndrome die in infancy. Anticonvulsant helps little in controlling the seizures and halting the deterioration of psychomotor development. [europeana.eu]

In patients with Unverricht-Lundborg disease or with mitochondrial encephalomyopathy with ragged red fibers the prognosis is slightly better but highly variable. 20 Though the prognosis in PME remains poor, progression is nowadays much slower and life [jamanetwork.com]

Mutations in the EPM2A gene prevent cells from making functional laforin, while NHLRC1 gene mutations prevent the production of functional malin. It is unclear how a loss of either of these proteins leads to the formation of Lafora bodies. [ghr.nlm.nih.gov]
