Neurodegenerative disease is an umbrella term for a range of conditions, which primarily affect a particular type of cell in the human brain, called neurons.
Neurons are the building blocks of the nervous system that includes the brain and spinal cord. Neurons normally don’t reproduce or replace themselves, so when they become damaged or die our bodies cant replace them.
Neurodegenerative diseases are incurable and debilitating conditions that result in progressive degeneration and / or death of nerve cells. This causes problems with movement (called ataxias), or mental functioning (called dementias).
