The majority were females (83.3%), married (53.8%), with a mean age of 44 (±12.2) years old. There was psychiatric comorbidity in 88.1% of the evaluated patients, of which 54.8% had two or more and 33.3% had only one. Major depression was the most prevalent (53.7%), followed by dysthymia (21.4%) and recurrent depression (14.6%). The risk of suicide was observed in 54.8% of subjects with GAD.
