Brain aging involves structural, functional, and molecular changes within the central nervous system over time. These changes include reduced brain volume, altered synaptic connectivity, and decreased neuroplasticity. Brain aging also affects cerebral blood flow, neurotransmitter balance, and cellular maintenance processes. Accumulation of molecular damage, inflammation, and mitochondrial dysfunction contributes to neural vulnerability. Brain aging influences cognition, motor coordination, emotional regulation, and sensory processing. Importantly, brain aging is heterogeneous and can be modified by lifestyle, cardiovascular health, and cognitive engagement. Understanding brain aging provides insight into maintaining neurological health and delaying the onset of age-related neurological disorders.
