/ˌnjʊərəʊˌdiːdʒɛnəˈreɪʃən/

Definition

The progressive loss of structure or function of neurons in the brain or nervous system, which contributes to chronic non-communicable diseases.

Etymology

The word is a combination of the Greek 'neuron' (nerve) and the Latin 'degenerare' (to depart from one's kind or decline). It entered modern medical terminology to describe the physiological deterioration of nervous tissue.
