The Crucial Role of Dendrites in Aging: From Pruning to Plasticity

Dendrites, the branching projections of neurons, undergo significant morphological and functional changes during the aging process. A key finding is that neurons experience a reduction in the complexity of their dendritic arborization and a decrease in dendritic length with advancing age, contributing to observable declines in cognitive function. Understanding these transformations is critical for revealing the underlying mechanisms of age-related cognitive impairment and developing interventions to promote healthy brain aging.

Do dendrites increase with age? The complex relationship between aging and dendritic changes

While it was once widely believed that significant neuron loss and dramatic deterioration of dendrites defined the aging brain, new research has painted a more nuanced picture. The answer to the question, "Do dendrites increase with age?", depends heavily on the specific region of the brain and an individual's overall health. The process involves a complex interplay of growth, regression, and neuroplasticity that continues throughout life.
