RESULTS: The 12-month prevalence of ADHD was 59.0 % (severe symptomatology: 33.1 %), high rates of comorbid disorders (92.9 % depression, 5.1 % bipolar disorder, 28.6 % anxiety disorder, 30.6 % emotional unstable (Borderline) personality disorder, 31.6 % avoidant personality disorder, 18.4 % dependent personality disorder, 25.5 % combined personality disorder, 10.2 % obsessive-compulsive personality disorder, 26.5 % PTSD, 25.5 % restless legs syndrome, 24.5 % adiposity, 11.2 % eating disorder, 45.9 % learning difficulty, 51.0 % nicotine dependency, 4.1 % alcohol dependency, 7.1 % illegal substance dependency), risk factors for ADHD, a high genetic risk (72.4 %) and problems in psychosocial functioning.
