Pisomnia 

Short for “Pi Insomnia.” When someone struggles to sleep after listening to a math lesson, or reading a geometry book, that repeatedly mentions the irrational number π.

Guesstimate how many folks worldwide suffer even from a mild form of pisomnia, where presently there seems to be no cure for the mathematically induced mental condition.
