| | Myoclonus - Wikipedia, the free encyclopedia |
 | | Myoclonus is brief, involuntary twitching of a muscle or a group of muscles. | | | Anatomically, myoclonus may originate from lesions of the cortex, subcortex or spinal cord. | | | Scientists are seeking to understand the biochemical basis of involuntary movements and to find the most effective treatment for myoclonus and other movement disorders. |

| | Myoclonus may affect only one hand, a group of muscles in the upper arm or leg, or a group of facial muscles. | | | Hiccups are a type of myoclonus that involves only the diaphragm, the muscle that separates the chest from the abdomen. | | | Thus, severe myoclonus can worsen an older person's quality of life and lead to undernutrition. |

| | The origin of essential myoclonus is idiopathic, and the condition progresses slowly or not at all. | | | Myoclonus involves a quick and simple jerk, whereas the jerking in chorea combines with other, slower movements in a continuous, flowing fashion. | | | Posthypoxia myoclonus is considered a cortical reflex myoclonus, because a cortical origin has been established. |

| | Hereditary essential myoclonus is an autosomal dominant, benign form of myoclonias in which the affected patients lack any other neurological or laboratory findings. | | | Myoclonus can clinically be classified according to its distribution, presentation, source and etiology [1]. | | | Hereditary essential myoclonus is thought to be a result of subcortical neuronal discharges. |

| | This particular dog's gait is affected by the myoclonus; its gait also may reflect a degree of transverse myelopathy as well, for transverse myelopathy occurs commonly in distemper in the absence of myoclonus. | | | The myoclonus may appear in only one small group of muscles or it may be nearly body wide; sometimes it appears to affect the diaphragm, although I have not been able to verify this. | | | Importantly, Breazile et al, 1966 published some very interesting data indicating that the mechanism for myoclonus was located in the spinal cord. |
