Presentation
This disease presents no sex-related differences and it is predominantly found in southern European countries. [elsevier.es]
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]
Neurologic
- Ataxia
Autosomal-Recessive Progressive Myoclonus Epilepsy-Ataxia Syndrome age of onset with ataxia at 4–5 years. Myoclonus starts at 5–10 years with a mean at 7 years. Impaired up-gaze. The intellect is usually preserved an neuroimaging studies are normal [slideshare.net]
Diseases related with Ataxia and Myoclonus In the following list you will find some of the most common rare diseases related to Ataxia and Myoclonus that can help you solving undiagnosed cases. [mendelian.co]
Clinical Features Progressive myoclonic epilepsy 6 (EPM6) is a neurological disorder characterized by early onset ataxia and myoclonic seizures. The first symptom of EPM6 is ataxia with onset around 2 years of age. [preventiongenetics.com]

Workup
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]
Treatment
The medical treatment of progressive myoclonic epilepsy is limited to supportive and symptomatic treatment. The treatment is often successful only for a few months or years. There is no current cure for PME. [epilepsy.com]
Brand-new chapters in the drug and diet section cover perampanel, ezogabine, and lacosamide, while the existing chapters on major medical treatments have been comprehensively updated to reflect the latest trials and studies. [books.google.de]
Lamotrigine was noted as an effective treatment for infantile and juvenile neuronal ceroid lipofuscinosis. [statpearls.com]
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]
Prognosis
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]

Etiology
Recently, PMEs have been recognized as a group of syndromes with specific etiologies. However, few studies demonstrated the EEG changes in PME in details. [journals.lww.com]
Despite increasing knowledge of the etiology of most progressive myoclonus epilepsy disorders, the pathogenic mechanisms leading to neurodegeneration and epilepsy remain largely unknown. • Histological and/or genetic studies are frequently required to [medlink.com]

Over the last two decades, considerable developments have occurred in the field of PMEs and they have been recognized as a group of syndromes with specific etiologies. [2],[3],[4] Genetic tests had further enhanced the understanding of the disease process [neurologyindia.com]
Epidemiology
From basic mechanisms and epidemiology, through diagnosis and therapy, to quality of life issues, the new edition of this established reference covers every aspect of childhood epilepsy and will continue to be the definitive core text for all professionals [books.google.de]
Epidemiology[edit] PME accounts for less than 1% of epilepsy cases at specialist centres. [en.wikipedia.org]
Pathophysiology
But recognizing the phenomenology and understanding the pathophysiology are essential to ensure appropriate treatment. Hyperkinetic Movement Disorders provides a clinical pathway for effective diagnosis and management of these disorders. [books.google.de]

Our results indicate that the changes in both the thalamus and putamen may play an important role in the pathophysiology of EPM1. Further studies in larger patient materials will show whether 3D TA could be a relevant tool for clinical applications. [journals.plos.org]

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]
As a result, laforin or malin deficiency would prevent digestion of polyglucosans and result in their accumulation (Figure 5B).[16] Figure 5. Two recent theories of the pathogenesis of Lafora bodies. [medscape.com]
