Recent advances in near-infrared spectroscopy (NIRS) have enabled noninvasive investigations of brain function in various mental disorders, especially major depression, schizophrenia, and bipolar disorder. The objective of this preliminary study was to use NIRS to evaluate changes in frontal lobe blood flow in post childhood or adult patients with AD/HD symptoms. The subjects included five patients with a range of mental disorders and AD/HD symptoms, and a matched (age, sex, and dominant hand) control group of five healthy subjects. We compared the changes in cerebral blood flow during verbal fluency tasks between the two groups. The duration of the elevated oxygenated hemoglobin was notably shorter in the AD/HD group than that in the healthy control group. We suggest that the shorter elevation durations of oxygenated hemoglobin concentrations might be a biological indicator for post childhood or adult AD/HD or of impaired executive functioning.展开更多

Fifteen consecutive adult Asperger’s disorder patients with ADHD symptoms were treated with milnacipran for 8 weeks. Global Assessment of Functioning (GAF) and Conners’ Adult ADHD Rating Scales Objective Screening Version (CAARS-O-SV) were used for the assessment. The mean GAF scores in the 15 patients improved significantly. Inattention, inattention + hyperactivity/impulsivity and ADHD index in CAARS-O-SV were also significantly improved. Milnacipran might be useful for ADHD symptoms, exerting its effects by increasing serotonin and noradrenaline activities in Asperger’s disorder.展开更多
