Mitochondrial Dysfunction: The Cellular Bridge from Emotional Stress to Disease Onset: A Narrative Review

Area of Science:

• Neuroscience
• Cell Biology
• Public Health

Background:

• Severe emotional stress is a public health issue linked to adverse health outcomes.
• Biological mechanisms linking stress to systemic disease are not fully understood.
• Stress impacts mitochondria, affecting energy production and cellular function.

Purpose of the Study:

• To propose mitochondria as the subcellular link in the mind-body connection.
• To introduce the concept of mitochondrial allostatic load (MALT).
• To explore diagnostic and therapeutic strategies for stress-related disorders targeting mitochondria.

Main Methods:

• This is a narrative review.
• Focuses on the concept of mitochondrial allostatic load (MALT).
• Examines diagnostic biomarkers and therapeutic interventions.

Main Results:

• Mitochondria act as a key link between psychological stress and cellular dysfunction.
• Mitochondrial allostatic load (MALT) describes the decline in mitochondrial function under chronic stress.
• Mitochondria can transition from adaptive responders to drivers of multi-organ disease.

Conclusions:

• Mitochondrial health is a potential target for preventing and treating stress-related disorders.
• MALT provides a framework to understand the biological impact of stress.
• Mitochondrial care can be integrated into precision medicine for stress-related conditions.
