Some scientists have proposed that damage to this brain region might help explain why some people experience long COVID symptoms, which include: fatigue. brain fog. breathlessness. mental health ...
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
Apraxia is a motor disorder caused by damage to the brain, and may be more common in those who have been left brain damaged, with loss of mechanical knowledge critical. [19] Headaches, occasional dizziness, and fatigue—all temporary symptoms of brain trauma—may become permanent, or may not disappear for a long time.
Fatigue in a medical context is used to cover experiences of low energy that are not caused by normal life.

First he fell, and "the fall caused the drainage tube that was going into his brain to be yanked out," according to the GoFundMe. Then, he needed a feeding tube as he is "trying so hard to eat ...
If the presynaptic vesicles are released at a faster rate into the synaptic cleft than re-uptake can recycle them, synaptic fatigue begins to occur. Synaptic fatigue , or short-term synaptic depression , is an activity-dependent form of short term synaptic plasticity that results in the temporary inability of neurons to fire and therefore ...
A page or photograph which shows the same image twice, but slightly displaced–from a printing mishap, a camera moving during the shot, etc.–can cause eye strain due to the brain misinterpreting the image fault as diplopia and reacting by adjusting the sideways movements of the two eyeballs, in an attempt to fuse the two images into one.
