(genetic, progressive) A cortical disease that affects the basal ganglia and is associated with progressive/extensive brain damage in the caudate nucleus, putamen, globus pallidus, and cortex. It is a genetic disease in which the there is a gene culled. 1 in 10,000 in the u. s. (much less common than parkinson"s) The initial motor symptoms include arm jerks and facial twitches, followed by tremors and writhing that affects the person"s voluntary movements. Nonmotor symptoms include cognitive difficulties from premotor functioning breakdown and connection caudate to frontal lobe. They are complex processes which an individual optimizes his or her performance in a situation that requires the operation of a number of cognitive processes. They are associated with the prefrontal cortex, but not clear if all executive functions can be localized in this region. Executive functions are higher levels of cognitive processing that organize and plan behavior, including reasoning, logic, and abstract reasoning.
