Presentation
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]
This disease presents no sex-related differences and it is predominantly found in southern European countries. [elsevier.es]
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]

The second case was a 21-year-old Turkish female given perampanel at a dose of 8 to 10 mg in addition to a regimen that included clonazepam, levetiracetam, piracetam, valproate, zonisamide, a ketogenic diet, and vagal nerve stimulation (VNS). [statpearls.com]
In addition, four variant forms of the disease have been described: Finnish, Gypsy/Indian, and Turkish variants of late-infantile NCL and Northern epilepsy. [clinicalgate.com]
These 4 types of variant LINCL are virtually indistinguishable clinically so are sometimes called Finnish, Czech, or Turkish variant LINCL, respectively, because they were first described in families from these countries. [bioline.org.br]

Ears
- Hearing Impairment
Depending on the type of PME, patients may also experience gastrointestinal and thyroid problems, as well as vision or hearing impairment. Weight control may be a problem for inactive patients. [rarediseases.org]
Psychiatrical
- Suggestibility
Under this situation, the gene screening was suggested, and the following result showed mutation in CLN6, which contributed to the diagnosis of LINCL. [journals.lww.com]
The findings suggest altered immune response of the CNS of some patients with PME apparently caused by nonspecific immunostimulation. [jamanetwork.com]
Epilepsy in Down syndrome is associated with dementia, and all these points suggest that a common underlying physiopathology may exist. Key words: Dementia; Down syndrome; epilepsy. [go.gale.com]
Our data suggests LEV as an alternative (42% seizure free for ≥1 year) whereas LTG was poor (15% seizure free for ≥1 year). [frontiersin.org]
Neurologic
- Seizure
Multifocal myoclonic seizures begin between 16 and 24 months of age after normal initial development. Neurodegeneration and regression occur with seizure onset. [malacards.org]
In addition, partial seizures rather than generalized seizures (generalized tonic-clonic or myoclonic) were commonly presented in the occipital epilepsy. [journals.lww.com]
The syndrome of PME consists of myoclonic seizures, tonic–clonic seizures, and progressive neurologic dysfunction, particularly ataxia and dementia. Onset - Any age (usually in late childhood or adolescence). 3. Progressive myoclonus epilepsy [slideshare.net]
The infant develops normally for the first year or so of life and the seizures start usually before the age of two. Once the seizures start, neurological degeneration begins. [checkorphan.org]
- Myoclonus

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]

The generalized seizures are usually well controlled by anticonvulsants, but the myoclonus soon proves refractory to treatment. [en.wikipedia.org]
The progressive myoclonus epilepsies (PME) are a particular subtype of seizure disorders characterized by progressive myoclonus, generalized seizures and cognitive deterioration. [epilepsygenetics.net]
- Mental Deterioration
Mental deterioration accompanies the disease progression. However, the progression of the disease in EPM1 is slower than in most other forms of the syndrome. The duration and seriousness of EPM1 are variable. [rarediseases.org]
Workup
[…] activator protein PTG and interaction with laforin.[21] Because of clinically atypical features, some patients with mild Lafora disease could escape a correct diagnosis because adult patients with mild PME traditionally have not undergone diagnostic workup [thieme-connect.com]
Treatment
Lamotrigine was noted as an effective treatment for infantile and juvenile neuronal ceroid lipofuscinosis. [statpearls.com]
Treatments For many patients, correct treatment can lower or prevent seizures. The most common treatment is anti-seizure medications. However, other treatment options are available. [cedars-sinai.edu]
There is no specific treatment for the disease. [clinicalgate.com]
Treatment The medical treatment of progressive myoclonic epilepsy is often successful only for a few months or years. These patients may require more than one seizure medicine. [checkorphan.org]
Prognosis
Prevalence Genetics Brain Area Affected Prognosis Rare. Exact prevalence is unknown. Caused by mutations in the MT-TK gene in 80% of cases. [tempobioscience.com]
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]

These diseases as a group are important because of a generally poor response to antiepileptic medication, an overall poor prognosis and inheritance risks to siblings or offspring (where there is a proven genetic cause). [pn.bmj.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]
