Cognitive-Decline

What Is Cognitive Reserve and How Do High Performers Build It? A Neuroscience Framework Cognitive reserve is the brain’s capacity to sustain function under neural stress by recruiting alternative networks when primary ones degrade. It is built cumulatively over a lifetime through education, occupational complexity, and cognitively demanding leisure — and measured structurally via cortical thickness, hippocampal volume, and white-matter integrity preserved into late life. ...

How to Improve Synaptic Plasticity: LTP/LTD Mechanisms and Evidence-Based Training Protocols Synaptic plasticity improves when precisely timed inputs drive NMDA-dependent calcium influx above the threshold that triggers AMPA receptor insertion. That mechanism runs in every decade of adult life. Sleep, exercise, and high-intensity skill rehearsal all modulate it — chronic stress and sleep loss actively suppress it. ...
