The life expectancy of someone with Huntington's is around
 50 to 60 years of age.  Most people develop the symptoms
 around 40 and there mind slowly deteriorates for 10 to 20 
years.   There are no cures for Huntington's disease, but
 there are medicines that can make it more bearable but with
 many risks. Tetrabenazine can help control the writhering,
jerking body movements, but it may lead to even severer
depression.  Antipsychotic drugs can control chorea, but
 they can also lead to worsened muscle rigidity.  Other
 medications, such as antiseizure drugs, can suppress
 dystonia, chorea, and muscle rigidity, but they have high
 abuse rates.
