Cognitive impairment is associated with mitochondrial dysfunction in peripheral blood mononuclear cells of elderly population
Abstract Cognitive impairment is commonly found in the elderly population. Evidence suggests that mitochondrial function in lymphocytes are potential biomarkers in the progression of neurodegeneration, as peripheral mitochondrial function is associated with mild cognitive impairment (MCI) in the eld...
