- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

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 website 2006]------------
