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 neuronal degeneration or depigmentation (loss of melanin in a neuron) in the substantia nigra. Additional distinguishing neurological features of those diagnosed with CBD consist of asymmetric atrophy of the frontal and parietal cortical regions of the brain. Postmortem studies of patients diagnosed with CBgD indicate that histological attributes often involve ballooning of neurons, gliosis, and tauopathy. Much of the pioneering advancements and research performed on CBgD has been completed within the past decade or so, due to the relatively recent formal recognition of the disease. Corticobasal degeneration Corticobasal ganglionic degeneration (CBgD or CBGD) is a rare, progressive neurodegenerative disease involving
