Presentation
We describe a large series of patients presenting with PED. [ncbi.nlm.nih.gov]
We present 2 cases where PED was the presenting feature of young‐onset idiopathic Parkinson's disease (PD), preceding the onset of parkinsonian symptoms by 1.5 and 5 years, respectively. [doi.org]
We describe a novel dominant disease in a three-generation family with four affected individuals presenting with acanthocytosis, paroxysmal exertion-induced dyskinesias and epilepsy. [thieme-connect.com]

Workup
In summary, here we show that PED can be associated with a number of different disorders, highlighting the need for a rational diagnostic workup. [ncbi.nlm.nih.gov]
We describe the case of a young female patient who was admitted for diagnostic workup: epileptic seizures versus psychogenic movement disorders. [e-jmd.org]
Treatment
Management and treatment There is no specific cure or treatment but avoiding precipitating events such as prolonged physical exercise may largely improve the symptoms. [orpha.net]

An inaccurate psychiatric diagnosis not only causes unnecessary suffering to the person affected by PD, but it may also preclude appropriate treatment options. Treatment There is no cure for dystonia or PD at this time, but treatments are available. [dystonia-foundation.org]

Typically, patients receive antiepileptic medications, and improvement of symptoms is usually associated with a good prognosis. If symptoms do not improve with antiepileptic medication(s), the prognosis is not favorable. [encyclopedia.com]
Prompt recognition of the underlying etiology is crucial for subsequent management, prognosis, and genetic counseling of these patients. The algorithm presented here might serve this aim. [ncbi.nlm.nih.gov]
The diagnosis of PKD is based on the clinical features and the correct diagnosis has implications for treatment and prognosis. However, PKD is often misdiagnosed clinically as epilepsy or psychogenic illness. [jmedicalcasereports.biomedcentral.com]
Etiology
However, the underlying etiology of PED is quite heterogeneous. We describe a large series of patients presenting with PED. [ncbi.nlm.nih.gov]
Etiology The pathophysiology of PED is still unknown but some familial cases were found to be associated with mutations in the SLC2A1 (solute carrier family 2 (facilitated glucose transporter), member 1) gene (1p34.2). [orpha.net]

Epidemiology
Summary Epidemiology The prevalence is unknown but 20 sporadic cases and 9 families have been described to date. Clinical description The age of onset is usually in childhood, but may range from 1 to 30 years. [orpha.net]

Pathophysiology
However, its pathophysiological and anatomical basis are poorly understood. [ncbi.nlm.nih.gov]
Recent genetic discoveries may aid us in elucidating the pathophysiology of these disorders. [mayoclinic.pure.elsevier.com]

Prevention
Experts stumped as to what to do in kids both to prevent and treat it. [medscape.com]
Moreover, a ketogenic diet for patients may prevent attacks and may lead to improvement of developmental delay in affected children. The documents contained in this web site are presented for information purposes only. [orpha.net]
