In mice, a stress protein weakens brain energy use and hurts memory and learning.
A protein called WASF3 builds up when cells are stressed. In mice, too much of it in a brain area used for memory caused brain cells to switch to a weaker energy system. This made the mice learn less well. Mice with no WASF3 kept using the stronger energy system and learned normally even under stress.
Shows a possible brain mechanism behind "brain fog" in chronic fatigue syndrome, tested only in mice.
Mouse study only, no human brain data yet.
