Biology-based criteria for diagnosis, staging of Alzheimer's disease

The Alzheimer's Association has published revised criteria for the diagnosis and staging of Alzheimer's disease that are based on the biology of the disease and reflect recent advancements in research, diagnostics and treatment.

How we can slow down or prevent Alzheimer's

Getting more than six hours of quality sleep a night may help prevent, or slow the progression of Alzheimer's disease, according to new research from Murdoch University. The study, "Suboptimal self-reported sleep efficiency ...

Blood test could predict Parkinson's seven years before symptoms

A team of researchers, led by scientists at UCL and University Medical Center Goettingen, has developed a simple blood test that uses artificial intelligence (AI) to predict Parkinson's up to seven years before the onset ...

Neurodegenerative disease

Neurodegenerative disease (Greek νέυρο-, néuro-, "nerval" and Latin dēgenerāre, "to decline" or "to worsen") is a condition in which cells of the brain and spinal cord are lost. The brain and spinal cord are composed of neurons that do different functions such as controlling movements, processing sensory information, and making decisions. Cells of the brain and spinal cord are not readily regenerated en masse, so excessive damage can be devastating. Neurodegenerative diseases result from deterioration of neurons or their myelin sheath which over time will lead to dysfunction and disabilities resulting from this.

Some sources limit the term "degenerative" to conditions primarily affecting gray matter that are not associated with a obvious inciting event.
