Artificial organ a stationary power supply or other stationary resources such as filters or chemical processing units. (Periodic rapid recharging of batteries, refilling of chemicals, and/or cleaning/replacing of filters would exclude a device from being called an artificial organ.) Thus, a dialysis machine, while a very successful and critically important life support device that almost completely replaces the duties of a kidney, is not an artificial organ. Constructing and installing artificial organs, an extremely research-intensive and expensive process initially, may entail many years of ongoing maintenance services not needed by a natural organ.: The use of any artificial organ by humans is
Corticobasal degeneration need to go, due to eventual loss of speech. Therefore, proper hygiene is mandatory to prevent urinary tract infections. CBgD was first identified by Rebeiz and his associates in 1968, as they observed three individuals who exhibited characteristic symptoms of the unique and previously unknown disorder. They initially referred to the neurodegenerative disease as "corticodentatonigral degeneration with neuronal achromasia", after which various other names were used, including "corticonigral degeneration with nuclear achromasia" and "cortical basal ganglionic degeneration". Although the underlying cause of CBgD is unknown, the disease occurs as a result of damage to the basal ganglia, specifically marked by
