I wouldn’t be surprised if that were the case.
ADD/ADHD/whatever they’re calling it now isn’t a real disorder. Attention doesn’t operate like other variables because everybody has it. You cannot have a deficit, unless you’re in a coma. If you put the average ADD kid in a forest, it’d disappear. Like magic. [yes I have tested that theory] Why? School is boring as shit [dumb teachers, unchallenged gifted trope] and bad parenting that would rather drug the poor kid up to the eyeballs than face a tough conversation once in a while about what a terrible job they’re doing and how to better support the kids’ needs. Notice the parents never require drugs with a long list of side effects, even though they say it’s genetic to feel less like the total scum they know deep down they are?
A woman who experienced this sensory overstimulation found that it subsided about 20 minutes after taking a potassium supplement. A neurologist found that her symptoms were the same as in “hypokalemic periodic paralysis,” where ion channels in the muscles become overactive when potassium levels are low.
K is a vital element in the body, especially the brain. Look up the sodium-potassium pump.

What caught my eye was this;
eating a high-carb diet and eating salty foods triggered her sensory overstimulation
Yes, that makes sense. Most salt is pure sodium, no trace minerals (the reason we crave it aside from simple electrolyte balance). There must be a BALANCE of Na AND K for the brain ‘pump’ messaging signals to operate effectively.
Practically speaking, anyone who eats too much salt and too little potassium is giving themselves brain damage. For those who didn’t read the “vital” link [tut tut]: “If the pump does not function properly in brain cells, the result is severe neurological conditions such as migraine with aura, muscle spasms or unilateral paralysis (hemiplegia).”
n.b. To the nootropic crowd, upping K doses is a thing (esp. to cover dietary high-salt intake). You’re welcome.
