Analyzing clinical and electrophysiological characteristics of Paroxysmal Dyskinesia
نویسندگان
چکیده
The classification, clinical and electrophysiological characteristics, treatment outcome and pathogenesis of paroxysmal dyskinesia were summarized and analyzed. Paroxysmal dyskinesia was classified into three types. Different types had different incentives in clinical practice. Patients were mostly male adolescents, and the attacks, which were in various forms, manifested as dysmyotonia of choreoathetosis, body torsion and facemaking; no disturbance of consciousness during attacks. Electroencephalogram and other examinations showed no specific abnormalities during both the attacks and interictal period. Paroxysmal dyskinesia was an independent disease and different from epilepsy.

INTRODUCTION Paroxysmal kinesigenic dyskinesia is characterized by sudden attacks of involuntary movements. It is often misdiagnosed clinically as psychogenic illness, which distresses the patients to a great extent. A correct diagnosis will improve the quality of life in patients with paroxysmal kinesigenic dyskinesia because treatment with low doses of anticonvulsants is effective for elimina...

Background & Objective: Recently, mutations in PRRT2 have been found to cause paroxysmal kinesigenic dyskinesia (PKD). However, only several reports have described the detailed clinical features of patients with the PRRT2 mutation compared to those without the mutation. Furthermore, 16p11.2 microdeletions including PRRT2 also have been reported in patients with PKD; however, it is unknown to wh...

Other than tremor, movement disorders are uncommon in multiple sclerosis. Among these uncommon clinical manifestations, paroxysmal kinesigenic dyskinesia is the most frequently reported. It is characterized by episodic attacks of involuntary movements that are induced by repetitive or sudden movements, startling noise or hyperventilation. The diagnosis is essentially clinical and based on a goo...
متن کاملNovel familial cases of ICCA (infantile convulsions with paroxysmal choreoathetosis) syndrome.
Epilepsy and paroxysmal dyskinesia are two episodic cerebral disorders that can share a common genetic basis. Rare families with infantile seizures and paroxysmal dyskinesia [predominantly paroxysmal kinesigenic dyskinesia (PKD)], co-inherited as a single autosomal dominant trait, have been described (infantile convulsions with paroxysmal choreoathetosis; ICCA syndrome) and a disease gene has b...
متن کاملPreprogramming motor dysfunction in paroxysmal kinesigenic choreoathetosis.
Paroxysmal kinesigenic choreoathetosis (PKC) is characterized by abnormal involuntary movements precipitated by sudden movement. As a result, a possible impairment of cerebral organization of voluntary motor activity is hypothesized in PKC. We examined a 14-year-old boy affected by a sporadic form of PKC, adopting a multimodal psychophysiological approach, including P300, contingent negative va...
