ABSTRACT
Neurodegenerative diseases are currently some of the most debilitating and incurable illness, including highly prevalent disorders, such as Alzheimer's and Parkinson's disease. Despite impressive advances in understanding the molecular basis of neurodegenerative diseases, several clinical trials have failed in identifying drugs that successfully delay or stop disease progression. New targets are likely necessary to successfully combat these devastating diseases. In this chapter, we review the evidence indicating that impairment in the cellular energy machinery in the form of mitochondrial damage and dysfunction may be at the root of neurodegeneration. We also propose that transplant of functional isolated mitochondria may overcome the energetic damage and delay the progression of neurodegenerative diseases.
