Inattention and hyperactivity dimensions of ADHD are associated with different personality profiles.

Background: Previous studies have suggested that individuals with ADHD have high scores in novelty seeking and harm avoidance. However, it is not known whether personality is associated with specific subtypes and dimensions of the disorder. The aim of this study is to test for associations between scores in the temperament and character inventory of C.

Late-onset ADHD in adults: milder, but still dysfunctional.

Objective: The requirement in classificatory systems that some impairment from attention-deficit/hyperactivity disorder (ADHD) symptoms starts before 7 years of age (age of onset of impairment criteria - AOC) has been harshly criticized. Although there is evidence that late-onset ADHD is a valid diagnosis, little is known about the role of age of onset of impairment on the clinical profile of adult patients.

Methods: The diagnoses of 349 adults with ADHD followed DSM-IV criteria.

Smoking is associated with lower performance in WAIS-R Block Design scores in adults with ADHD.

Adults with attention-deficit/hyperactivity disorder (ADHD) are predisposed to smoking, but the neuropsychological correlates of this association have not been elucidated so far. The present study evaluates possible associations between cognitive performance and smoking and other comorbidities in adults with ADHD. Two hundred and sixty-four (264) patients were evaluated in the adult ADHD outpatient clinic of the Hospital de Clínicas de Porto Alegre.

The role of comorbid major depressive disorder in the clinical presentation of adult ADHD.

Most adults with attention-deficit/hyperactivity disorder (ADHD) are not recognized and remain untreated, although a large fraction of these individuals are diagnosed and treated for other comorbid mental disorders, such as major depressive disorder (MDD). The fact that MDD is one of the most commonly occurring mental disorders with high comorbidity with adult ADHD raises the question whether such comorbidity is associated with differences in the clinical picture of ADHD. Three hundred and twenty adult ADHD outpatients were evaluated.

Lack of gender effects on subtype outcomes in adults with attention-deficit/hyperactivity disorder: support for the validity of subtypes.

The aim of the present study is to verify if gender modifies the clinical, adaptative and psychological outcomes of adult attention-deficit/hyperactivity disorder (ADHD) subtypes. We evaluated 219 clinically referred adult patients. The interviews followed the DSM-IV criteria,using the K-SADS-E for ADHD and oppositional defiant disorder and SCID-IV for comorbidities.
