Developmental motifs in neurodegeneration:Neurodegeneration,the prominent feature of neurodegenerative disease,is characterized by the progressive and selective loss of neuronal *** some of the pathologies caused by neurodegeneration may be irreversible,early intervention will be required for the treatments that aim to slow or halt the manifestation of these ***,neurodegeneration evokes the idea of a progressive decline of brain function.
