Such findings support a close link between oxidative damage and neuronal injury ( + , a metabolite transported into dopaminergic neurons via the dopamine transporter, accumulates in the mitochondria and inhibits complex I activity of the electron transport chain, reducing ATP production and increasing ROS release, ultimately causing degeneration of dopaminergic neurons in the substantia nigra and striatum ( 2.4 Relationship between aging and neurodegenerative diseases Given the high prevalence of neurodegenerative diseases in older adults, aging is considered the primary risk factor for neurodegeneration ( Beyond AD and PD, numerous other neurodegenerative diseases show strong associations with cellular senescence
