Short answer · Medically reviewed summary · Last updated: 2026-05-08
Paroxysmal Kinesigenic Choreathetosis (PKC), also known as Paroxysmal Kinesigenic Dyskinesia (PKD), is a rare movement disorder characterized by brief, recurrent episodes of involuntary movements triggered by sudden voluntary motion. The condition is most frequently referred to in modern medical literature as Paroxysmal Kinesigenic Dyskinesia to encompass the varied nature of the motor symptoms, which may include chorea, athetosis, or dystonia. What are the common synonyms for Paroxysmal Kinesigenic Dyskinesia? Because the clinical presentation involves various involuntary movements, Paroxysmal Kinesigenic Choreathetosis has historically been described by several names.

Paroxysmal Kinesigenic Choreathetosis (PKC), also known as Paroxysmal Kinesigenic Dyskinesia (PKD), is a rare movement disorder characterized by brief, recurrent episodes of involuntary movements triggered by sudden voluntary motion. The condition is most frequently referred to in modern medical literature as Paroxysmal Kinesigenic Dyskinesia to encompass the varied nature of the motor symptoms, which may include chorea, athetosis, or dystonia.
What are the common synonyms for Paroxysmal Kinesigenic Dyskinesia?
Because the clinical presentation involves various involuntary movements, Paroxysmal Kinesigenic Choreathetosis has historically been described by several names. Clinicians and researchers often use the terms interchangeably, though "dyskinesia" is now the preferred umbrella term. Common synonyms include:
- Paroxysmal Kinesigenic Dyskinesia (PKD)
- Familial Paroxysmal Kinesigenic Dyskinesia
- Kinesigenic Choreoathetosis
- Paroxysmal Kinesigenic Choreoathetosis
- Epilepsia Partia Continua (an archaic, now largely discarded term)
Why are there so many names for this condition?
The nomenclature for Paroxysmal Kinesigenic Choreathetosis has evolved as our understanding of its underlying pathophysiology has improved. Historically, the condition was named based on the specific movement observed by the physician, such as chorea (jerky movements) or athetosis (writhing). As genetic research—specifically the discovery of mutations in the PRRT2 gene—linked these presentations to a single underlying mechanism, the medical community moved toward the broader term Paroxysmal Kinesigenic Dyskinesia to unify the diagnosis.
How is the condition classified in medical databases?
Medical professionals use standardized coding to ensure consistency in research and clinical care for Paroxysmal Kinesigenic Dyskinesia. Key classifications include:
- OMIM: #128200 (Familial Paroxysmal Kinesigenic Dyskinesia)
- Orphanet: ORPHA73236
- ICD-10-CM: G24.8 (Other dystonia) or G25.9 (Extrapyramidal and movement disorder, unspecified)
