Neurodegenerative diseases constitute a large proportion of disorders in elderly, majority being sporadic in occurrence with $$\sim $$ ∼ 5–10% familial. A strong genetic component underlies the Mendelian forms but nongenetic factors together with genetic vulnerability contributes to the complex sporadic forms. Several gene discoveries in the familial forms have provided novel insights into the pathogenesis...
The use of animals as models of neurodegenerative disorders has allowed the determination of biological targets and biomarkers of several diseases, has yielded new therapeutical perspectives, and is essential before performing novel clinical assays. This review discusses the nature, use, and limits of animal models and how to obtain them for several neurodegenerative disorders such as multiple system...
Mitochondria are implicated in several metabolic pathways including cell respiratory processes, apoptosis, and free radical production. Mitochondrial abnormalities have been documented in neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and Huntington’s diseases, and amyotrophic lateral sclerosis. Several studies have demonstrated that mitochondrial impairment plays an important role...
