Research uncovers how genetic, cellular, and environmental influences interact to affect brain aging and cognition.

Neurodegenerative Changes

Accumulation of abnormal proteins such as beta-amyloid and tau disrupts neural function.

This leads to loss of synapses and neuron death.

Inflammation and Oxidative Stress

Chronic brain inflammation and oxidative damage accelerate cellular aging.

These processes impair brain plasticity and repair mechanisms.

Genetic and Lifestyle Factors

Genes like APOE4 increase susceptibility, while diet, exercise, and mental engagement modulate risk.

Understanding these factors aids prevention and treatment.

Implications for Therapeutics

Targeting multiple pathological pathways offers hope for slowing decline.

Personalized medicine approaches may optimize outcomes.
