Area of Science:

• Neuroscience
• Cell Biology
• Gerontology

Background:

• Mitochondrial dysfunction is central to aging and neurodegenerative diseases.
• Understanding its mechanisms is vital for developing effective therapeutic strategies.
• This review explores pathways of mitochondrial dysfunction in aging and neurodegeneration for potential intervention targets.

Purpose of the Study:

• To elucidate the mechanisms connecting mitochondrial dysfunction with aging and neurodegenerative diseases.
• To identify potential therapeutic targets for intervention.
• To synthesize current knowledge on mitochondrial dysfunction in aging and neurodegeneration.

Main Methods:

• Comprehensive literature review.
• Synthesis of current knowledge on mitochondrial dysfunction.
• Focus on key cellular and molecular pathways including structure, function, energy metabolism, and homeostasis.

Main Results:

• Aging mitochondria show reduced effectiveness, decreased ATP, impaired oxidative phosphorylation, and increased reactive oxygen species.
• Neurodegenerative diseases (Alzheimer's, Parkinson's, Huntington's) exhibit specific mitochondrial abnormalities like deficient mitophagy and mtDNA mutations.
• These mitochondrial issues contribute to neuronal cell death and disease progression.

Conclusions:

• Diverse mechanisms link mitochondrial dysfunction to aging and neurodegeneration.
• Identified pathways are critical for therapeutic intervention to preserve mitochondrial integrity.
• Further research into these pathways may yield novel treatments for age-related and neurodegenerative conditions.
