Cognitive Dysfunction and Exercise: From Epigenetic to Genetic Molecular Mechanisms.

Area of Science:

• Neuroscience
• Exercise Physiology
• Genetics

Background:

• Cognitive impairment is a growing concern with aging populations and neurodegenerative diseases.
• It leads to memory loss, confusion, and reduced quality of life, impacting emotional well-being and incurring societal costs.
• Current treatments primarily slow cognitive decline, highlighting the need for accessible interventions.

Purpose of the Study:

• To summarize the genetic and epigenetic mechanisms through which exercise modulates cognitive dysfunction.
• To explore exercise as a non-pharmacological intervention for maintaining cognitive health.
• To understand the intricate effects of exercise on brain function.

Main Methods:

• Review of existing literature on exercise, genetics, epigenetics, and cognitive function.
• Analysis of studies investigating the molecular and cellular changes induced by physical activity.
• Synthesis of findings related to neural plasticity, mitochondrial function, and cytokine release.

Main Results:

• Exercise positively impacts cognitive function across all ages.
• Mechanisms include enhanced neural plasticity, improved mitochondrial stability, and altered energy metabolism.
• Exercise-induced cytokine release and epigenetic modifications contribute to lasting brain health benefits.

Conclusions:

• Exercise is a safe and accessible strategy to improve cognitive function and combat cognitive decline.
• Understanding the genetic and epigenetic pathways offers new avenues for therapeutic development.
• Physical activity plays a crucial role in maintaining brain health and overall well-being throughout the lifespan.
