Abstract

Schizophrenia is an incapacitating mental disorder, which affects 5/1000 people in Brazil. The physiopathology of this disease is not completed elucidated and its treatment causes important collateral effects, such as motor disturbances, metabolic dysregulation and agranulocytosis. Multiple evidence show a pro-oxidative status in the disease, which can lead to oxidative stress damage, including decreased telomeric length. Recently, it has been suggested that schizophrenia is a syndrome of cellular aging, which was confirmed by some studies that report association between telomere's length and schizophrenia. However, this finding has not been confirmed in all papers, but a probable interference of antipsychotic treatment was inferred. The objective of this project is to evaluate the effect of 3 different antipsychotics, with distinct mechanisms of action, over the telomere length of leukocytes ex vivo of healthy individuals.
