* Infections in kids tied to subsequent mental illness risk.
The study, published in the journal JAMA Psychiatry on Wednesday, found that infections requiring hospitalizations were associated with an about 84% increased risk of being diagnosed with any mental disorder and an about 42% increased risk of using psychotropic drugs to treat a mental disorder. Less severe infections treated with anti-infective medications, like antibiotics, were associated with increased risks of 40% and 22%, respectively, the study found. . . .
The researchers found associations between any treated infection and the increased risk of later being prescribed medication for various childhood and adolescent mental disorders, with the risks differing for specific disorders.
Risks were increased for schizophrenia spectrum disorders, obsessive-compulsive disorder, personality and behavior disorders, mental retardation, autism spectrum disorders, attention-deficit hyperactivity disorder, oppositional defiant disorder/conduct disorder and tic disorders[.]
The last sentence of the first paragraph of the quotation from the news story above doesn't really make sense. The reason for the correlation is not known. The study does not support the claim that not treating an infection will prevent mental illness.
The data involve 1 million people in Denmark born from 1995 to 2012, which centralized health records make this kind of big data research possible and reliable. It is basically measuring childhood mental health conditions rather than adult conditions.
