Possibly the Funniest Misspelling

I won't quote the exact way it was used, but on a social media post today I saw a person spell the word dementia as dimensia.

It almost qualifies as an eggcorn, as if a person with dementia is in another dimension. That's a pleasant way to think of it, compared to the connotation of demented.

I never thought about the etymology of demented or dementia before now, but of course de- is from Latin, "away from" and -ment comes from mens, "mind."
