a
Each person could be diagnosed with multiple neurological disorders. The sum of numbers of persons diagnosed with individual disorders is therefore not equal to the number of persons diagnosed any with neurological disorders.
b
Full adjusted models were adjusted for period, sex, age group, living status, region, socioeconomic status, physical comorbidity, psychiatric hospitalization prior to diagnosis of any neurological disorders, and deliberate self-harm prior to diagnosis of any neurological disorders.
c
Other brain disorders were only defined in International Statistical Classification of Diseases and Related Health Problems, Tenth Revision.
