Definition

Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep; This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence; The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle; (Adams et al, Principles of Neurology, 6th ed, p387)-------------------------------------------------.

Myoclonus, General; Subdivisions:Action Myoclonus; Arrhythmic Myoclonus; Dyssynergia Cerebellaris Myoclonica; Familial Arrhythmic Myoclonus; Hereditary Essential Myoclonus; Infantile Myoclonic Encephalopathy and Polymyoclonia; Intention Myoclonus; Nocturnal Myoclonus; Opsoclonus; Palatal Myoclonus; Paramyoclonus Multiple; Pathological Myoclonus; Postanoxic Intention Myoclonus; Postencephalitic Intention Myoclonus; Progressive Myoclonic Epilepsy; Respiratory Myoclonus; Rhythmical Myoclonus; Segmental Myoclonus; Stimulus-Sensitive Myoclonus; Myoclonus is a neurological movement disorder characterized by sudden, involuntary contractions of skeletal muscles; Based on the various symptoms, there are three types of Myoclonus: Intention Myoclonus, Rhythmical Myoclonus, and Arrhythmic Myoclonus;

Intention Myoclonus (Action Myoclonus) includes Postanoxic Myoclonus and Postencephalitic Myoclonus; Arrhythmic Myoclonus (stimulus-sensitive myoclonus) includes: Hereditary Essential Myoclonus (paramyoclonus multiplex), Hyperexplexia (Essential Startle Disease), Opsoclonus (Infantile Myoclonic Encephalopathy, Polymyoclonia Familial Arrhythmic Myoclonus), Progressive Myoclonic Epilepsy, Ramsay Hunt Syndrome (Dyssynergia Cerebellaris Myoclonia);

Rhythmical Myoclonus includes (Segmental Myoclonus), Nocturnal Myoclonus, Palatal Myoclonus, and Respiratory Myoclonus; [NORD]
