Conditional logistic regression analyses were applied to estimate age\u2010 and multivariable\u2010adjusted odds ratios (ORs) for the occurrence of a primary brain tumour up to 10\u00a0years after hospital diagnoses or prescription of medications related to nervous system diseases and mental and behavioural disorders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Increased odds for primary brain tumour after nervous system diseases and mental and behavioural disorders manifested up to 10\u00a0years before tumour diagnosis were found.
