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
Cerebellar degeneration history of hereditary forms of cerebellar degeneration. A diagnosis for cerebellar degeneration is regarded after any of the aforementioned signs and symptoms surface. For genetically-classified forms of cerebellar degeneration, genetic testing can be carried out in order to confirm or deny the diagnosis, where this form of testing is only possible if the gene responsible for the cause of the condition is recognised. In saying this, for most conditions the genetic cause of cerebellar degeneration is unidentified, hence these patients cannot proceed with genetic testing. In cases where cerebellar degeneration is acquired, a diagnosis can be established using imaging methods
