What is the difference between Parkinson's and Huntington's disease?

Answer 1

Huntington's disease, also called Huntington's chorea, chorea major, or HD, is an inherited genetic neurological disorder characterized by abnormally uncoordinated, jerky body movements called chorea and a decline in some mental abilities, which can lead to affected aspects of behavior. As the disorder progresses, it can cause complications that significantly reduce life expectancy. Parkinson's disease (also known as Parkinson disease or PD) is a degenerative disorder of the central nervous system that often impairs the sufferer's motor skills and speech, as well as other functions. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia). It is chronic and progressive. It can be primary or secondary to an injury.
