We estimate that 3.4 billion people experienced some form of neurological health loss in 2021, which is a staggering number. This is largely due to certain conditions that are widespread. For example, tension-type headaches affected about 2 billion people in 2021.

Seems like they goosed their numbers here for a headline. Tension headaches aren’t well understood, but they’re generally not neurological.

I thought this was reporting on toxoplasmosis gondii. Nope, just depressing and scary dangerous disorders.

Which one? ^/s
