neurodegenerative

Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons. Many neurodegenerative diseases including amyotrophic lateral sclerosis, Parkinson's, Alzheimer's, and Huntington's occur as a result of neurodegenerative processes. Such diseases are incurable, resulting in progressive degeneration and/or death of neuron cells. As research progresses, many similarities appear that relate these diseases to one another on a sub-cellular level. Discovering these similarities offers hope for therapeutic advances that could ameliorate many diseases simultaneously. There are many parallels between different neurodegenerative disorders including atypical protein assemblies as well as induced cell death. Neurodegeneration can be found in many different levels of neuronal circuitry ranging from molecular to systemic.

Les maladies neurodégénératives, telles que la Maladie d'Alzheimer, la maladie de Parkinson, la Maladie de Huntington ou encore la sclérose latérale amyotrophique sont des maladies chroniques invalidantes à évolution lente et discrète. Elles provoquent généralement une détérioration du fonctionnement des , en particulier les neurones, pouvant conduire à la mort cellulaire (ou neurodégénérescence). Les troubles induits par les maladies neurodégénératives sont variés et peuvent être d'ordre cognitivo-comportemental, sensoriel et moteur.

Choroby neurodegeneracyjne (gr./łac.  (néuro-) = "nerwowy" oraz dēgenerāre, "degenerować") – grupa wrodzonych lub nabytych postępujących chorób układu nerwowego, w których podstawowym zjawiskiem patologicznym jest utrata komórek nerwowych.
