A few words of thanks would be greatly appreciated.

Huntington's disease


The term chorea refers to manifestations of neurological origin in the form of unexpected muscle contractions that generate random movements. Huntington's chorea, also known as Huntington's disease, is a rare neurological disorder whose transmission is hereditary. It manifests itself by the destruction of cells of certain parts of the brain, causing progressive atrophy - initially in deep parts of the brain, but generalizing to the entire brain. It mostly strikes people aged between 35 and 50. The disease occurs gradually, by abnormal movements called "chorea" coupled with a deterioration of intellectual function disorders. Eventually, the disease leads to death.


Symptoms of Huntington's disease are of a progressive nature:
  • motor troubles and clumsiness of movement;
  • personality disorders;
  • cognitive and intellectual disabilities;
  • loss of memory;
  • difficulty concentrating.


To make a diagnosis, the doctor will look at family history as the disease is usually hereditary. He will then base his diagnosis on clinical signs. A CT scan or MRI will reduce any doubt of diagnosis and highlight the areas of atrophy.


Huntington's disease is an incurable disease. The treatments that exist today are purely symptomatic, aimed mainly at making life easier for people by reducing abnormal muscle movements. Regular monitoring with care by neurologists, psychologists and physiotherapists is required.


There is no prevention against the onset of Huntington's disease. ==Symptoms== of Huntington's disease appear so late that the disease can be transmitted to children without parents even knowing that they are themselves affected. This is why it is possible to conduct a genetic test if the disease has been present in the family. However, this diagnosis poses an ethical question since there is no treatment.
