Autosomal recessive cerebellar ataxia type 1 (ARCA1) is a condition characterised by progressive problems with movement due to a loss (atrophy) of nerve cells in the part of the brain that coordinates movement (the cerebellum). Signs and symptoms of the disorder first appear in early to mid-adulthood. People with this condition initially experience impaired speech (dysarthria), problems with coordination and balance (ataxia), or both. They may also have difficulty with movements that involve judging distance or scale (dysmetria). Other features of ARCA1 include abnormal eye movements (nystagmus) and problems following the movements of objects with the eyes. The movement problems are slowly progressive, often resulting in the need for a cane, walker, or wheelchair.

Huntington's disease
What causes Huntington's disease. Huntington's disease is caused by a defective gene that you inherit from your parents. Huntington's disease is an autosomal dominant condition, meaning you can inherit the disease from just one of your parents. If one of your parents has a faulty copy of the gene, there is a 50:50 chance that each child they have.
