Age can make memory feel like something that only moves in one direction. A name slips away. A route you know well turns fuzzy. In Alzheimer’s disease, that slide can look even steeper. Yet the brain does not stop adapting. Neurons keep tuning the strength of their connections, and that constant adjustment, called synaptic plasticity, is what lets learning stick.
