The possible association between mobile phone use and the risk for central nervous system diseases was investigated in a nationwide cohort study in Denmark.
The participants were followed through 2003 for hospital contacts for a diagnosis of a CNS disorder. Standardized hospitalisation ratios were derived by dividing the number of hopital contacts in the study population by the number expected in the Danish population.
Type | Value |

Total | 723,421 |
Participants | 420,095 |
4 million person-years at risk
A small but significantly increased standardized hospitalisation ratio for migraine and vertigo was observed in the study population whereas the standardized hospitalisation ratios for Alzheimer disease, dementia, and Parkinson disease were all statistically significantly decreased. No associations were seen for amyotrophic lateral sclerosis, multiple sclerosis and epilepsy. The authors concluded that the excesses of migraine and vertigo deserve further attention.
