Mechanisms of Metal-Induced Mitochondrial Dysfunction in Neurological Disorders

Mitochondrial Dysfunction & Neurological Disorders

Most of the living organisms derive their energy requirements from ingested food material through controlled metabolic reactions. Prokaryotes like bacteria obtain the ATP, the energy subunit from series of enzymatic reactions which occur in the cytosol [1]. In contrast to prokaryotes, eukaryotes have evolved a highly specialized double membrane organelles i.e., mitochondria encompassing electro...

Mitochondrial Dysfunction in Neuropsychiatric Disorders

Mitochondrial disorders were first described in 1962 (Luft, Ikkos, Palmieri, Ernster, & Afzelius, 1962), and were initially thought to be uniformly progressive and fatal with onset in infancy or early childhood, typically associated with severe neurological manifestations, including strokelike episodes, seizures, neuronal degeneration, organ failure and dementia. More recently, clinical observa...

Mitochondrial dysfunction in neurodegenerative disorders.

There is compelling evidence for the direct involvement of mitochondria in certain neurodegenerative disorders, such as Morbus Parkinson, FRDA (Friedreich's ataxia), ALS (amyotrophic lateral sclerosis), and temporal lobe epilepsy with Ammon's horn sclerosis. This evidence includes the direct genetic evidence of pathogenic mutations in mitochondrial proteins in inherited Parkinsonism {such as PA...

Encyclopedia of Neurological Disorders: Mitochondrial Myopathies

Mitochondrial myopathies are a group of neuromuscular disorders that result from defects in the function of the mitochondrion, a small organelle located inside many cells that are responsible for fulfilling energy requirements of the tissue. These structures serve as "power plants" and are particularly important for providing energy for both muscle and brain function due to the large requiremen...
