Abstract Summary

A Danish study of 420,095 early cell phone users (1982-1995) found 10-20% increases in migraine and vertigo hospitalizations, but no links to ALS, MS, or most other CNS disorders. Surprisingly, dementia, Parkinson’s, and epilepsy rates were 30-40% lower in male users, likely reflecting “healthy user” bias rather than protective effects. The migraine/vertigo findings warrant further investigation.
