Huntington's Disease
Huntington's Disease is a neurological disease, degenerative, hereditary, autosomal and dominant. Each son or daughter of a parent with the disease has a fifty percent chance of inheriting it, regardless of whether their brothers or sisters have inherited or not. If the son or your daughter does not inherit from parents the gene causing the disease, not HD, nor will transmit to their descendants.
Huntington disease is characterized by dementia. Symptoms do not develop until after 30 years, so when the disease is detected the affected people likely to have offspring and so the disease continues from one generation to the next.
The disease is usually progressive and fatal in the course of fifteen to twenty years. As mentioned at the beginning of this disease occurs between 30 and 50 years of age.
Initial symptoms may include abnormal movements or intellectual changes, but eventually appear both.
Mental disturbances are often behavioral, with irritation, extravagances, antisocial behavior or psychiatric disorder, but later develop dementia more obvious.
The abnormal movements are characterized at first by a dyskinesia which can be only one agitation or restlessness, which evolve to appear choreiform and dystonic certain posture. Sometimes there is progressive rigidity and akinesia (instead of chorea) accompanied by dementia, particularly in cases that begin in childhood.
