#Neuralplasticity and #neurogenesis and the aging brain

The aging brain is a heterogenous process and varies individually, case by case. Neuroplasticity and neurogenesis aid the aging brain in creating new neural structure, thereby minimizing any impact of asymptomatic pre-clinical lesions.

• "Neuroplasticity, defined as the ability of the neuronal system to respond to intrinsic and external stimuli by reorganizing is structure, connections, and functions, is of great importance for the aging brain.
  
• Recent neuroimaging data have provided changes in aging brain that reflect compensatory mechanisms or neuronal restitution. Larger brain and hippocampal volumes and neuronal hypertrophy were associated with preserved cognition despite a high burden of AD pathology."
