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]

- Muscle Spasm
Symptoms of PME3 include seizures, loss of developmental skills, muscle spasms/contractions that may occur more frequently in the morning or when under stress, memory problems, impairment of vision and/or hearing, and possible depression. [diseaseinfosearch.org]

Myoclonus begins one to five years later when muscle spasms of the limbs and minor twitching motions become obvious. Later, these spasms may become so violent that the patient falls. Mental deterioration accompanies the disease progression. [rarediseases.org]

EEG
- Epileptiform Activity
EEG typically reveals epileptiform activity with predominance in the posterior region and photosensitivity. [orpha.net]
Generalized epileptiform discharges in 84.2% of patients, while focal discharges were present in ten patients. One of the patient had multifocal epileptiform activity. [bioline.org.br]
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]
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 [bioline.org.br]

Molecular genetics has emerged as a useful tool for enhancing subtype classification of neuronal ceroid lipofuscinoses.[25] There are 14 genetic forms (CLN1 to CLN14) described to date and 360 etiological mutations, most of which have been included in [thieme-connect.com]

To prevent worsening of myoclonus carbamazepine, phenytoin, gabapentin, pregabalin and lamotrigine should be avoided. [pubs.sciepub.com]
