Specific Aims:
- To examine the efficacy of atomoxetine in improving neuropsychological functioning (CANTAB, Time Perception Tasks) and structural (DSI) and functional (resting fMRI) brain connectivity as the primary efficacy endpoints.
- To examine the efficacy of atomoxetine in reducing ADHD core symptoms and in improving family/social/academic/occupational adjustment and quality of life.
The study design is a randomized open-label, methylphenidate control trial. The sample consists of 60 adults, aged 18-50, with clinical diagnosis of DSM-IV. All participants will be randomly assigned to atomoxetine (n= 30), methylphenidate (n= 15), and clinical visit with psychological counseling (n=15) in a 8-week randomized clinical trial with 3 treatment arms.
The measures included psychiatric interviews (ADHD+SADS), the CGI-ADHD-S, the standardized self-reported questionnaires (the AAQoL, WFIRS-S, and WFIRS-P for social function; ASRS for ADHD symptoms), neuropsychological tests (CANTAB including attention tasks, visual memory, executive functioning, and gambling test; Time Perception Task), and brain imaging (DSI and resting fMRI).
They will be reassessed with safety, ADHD symptoms and social functioning/quality of life at baseline, week 2 (± 5 days), week 4 (± 5 days), and week 8 (± 5 days); neuropsychological tests at baseline, week 4 (± 5 days), and week 8 (± 5 days); and brain imaging studies (DSI and resting-fMRI) at baseline and week 8 (± 5 days). Additionally, blood sample will be collected at baseline for future pharmacogenomic study.
We anticipate that this study will be one of the first to investigate the efficacy of atomoxetine on neuropsychological functioning, and structural and functional brain connectivity in the world. If this research can be carried out, it will be the first project using brain images as assessment tools in a clinical trial among psychiatric patients in psychiatric field in Taiwan.

説明
Inclusion Criteria:
- The inclusion criteria are (1) that subjects had typical ADHD symptoms before 7 years old which meet the DSM-IV-TR ADHD at childhood and currently based on Gau's clinic diagnosis and the ADHD supplement of the K-SADS for adults; (2) that their Clinical Global Impressions-ADHD-Severity (CGI-ADHD-S) score>4 and psychotropic medication-naïve for the past year; (3) that their IQ greater than 80; and (4) that they consent to this study and they can keep appointments for clinic visits and all tests.
Exclusion Criteria:
These subjects will be excluded from the study if they have any of the following criteria:
- (1) Comorbid with DSM-IV-TR diagnosis of pervasive developmental disorder, schizophrenia, schizoaffective disorder, delusional disorder, other psychotic disorder, organic psychosis, schizotypal personality disorder, bipolar affective disorder, and mental retardation; (2) In the major depressive episode, comorbid with severe anxiety disorders or during substance intoxication or withdrawal at the time of evaluation; (3) With neurodegenerative disorder, epilepsy, involuntary movement disorder, congenital metabolic disorder, brain tumor, history of severe head trauma, and history of craniotomy; (4) A history of alcohol or drug abuse within the past 3 months; (5) The need of psychotropic medications apart from MPH or atomoxetine, including Chinese medicine or health-food supplements that have central nervous system activity; and (6) With visual or hearing impairments, or motor disability which may influence the process of neuropsychological assessment. Subjects will be discontinued from this study in the following circumstances: pregnancy, non-compliance with study drug, an adverse event, subject's request of withdrawal, and loss of follow-up.
