Genetic risk meets retina
Previous studies have suggested that schizophrenia may be associated with a loss of gray matter in the brain and thinning of the retina. Yet it remains uncertain whether these changes contribute to the development of the disorder or emerge as a consequence of it.
Other variables — such as the effects of antipsychotic medications, lifestyle habits, or comorbid conditions like diabetes — could also play a role in altering the retina.
“To investigate whether the risk of developing schizophrenia has an effect on the central nervous system, we examined tens of thousands of healthy individuals,” first author of the study Finn Rabe said.
