RESUMEN
OBJECTIVE: In preclinical studies, lobeline inhibited hyperactivity induced by nicotine and amphetamine, and improved performance and learning in studies utilizing radial-arm maze and spatial-discrimination water maze. This laboratory proof-of-concept study investigated lobeline as a treatment for ADHD symptoms in adults (31.11 ± 7.08 years). METHOD: Using cognitive tasks and self-report measures, the effects of lobeline (0, 7.5, 15, or 30 mg, s.l.) and methylphenidate (0, 15, or 30 mg, p.o.) were assessed in nine volunteers with ADHD. RESULTS: Evidence suggested that lobeline could modestly improve working memory in adults with ADHD, but no significant improvement in attention was observed. Lobeline administration was associated with mild adverse side effects (nausea). CONCLUSION: Further investigation of lobeline on working memory may be warranted.

OBJECTIVES: This study examined the relationship between psychiatric symptoms and nicotine, caffeine, alcohol, and marijuana use in young adult smokers METHODS: Young adult smokers completed self-report measures of nicotine, caffeine, alcohol and marijuana use, Conner's Adult ADHD (Attention-Deficit/Hyperactivity Disorder) Rating Scale-Short Version (CAARS-SS), Beck Depression and Anxiety Inventories (BDI and BAI), and provided a breath carbon monoxide (CO) sample. RESULTS: Self-reported cigarette use was positively correlated with carbon monoxide, CAARS-SS and the BDI levels. Caffeine intake was correlated with CAARS-SS, BAI and BDI levels and emerged as the more significant predictor of BDI, BAI and CAARS-SS scores when regressed with cigarette use. CONCLUSIONS: Caffeine use is associated with psychiatric symptoms in young adult cigarette smokers and should be considered in future research.
RESUMEN
The objective of this study was to evaluate the relationship between caffeine use, other drug use, and psychopathology in adolescents, using self-report measures. The study group consisted of 132 adolescents (average age 14.01 +/- 2.06 years, 52% female, 19% African American, 5% other categories, 76% Caucasian). Most (47%) were recruited from a child psychiatry clinic with emphasis on youth with disruptive disorders, with 35% from an adolescent pediatric clinic with emphasis on prevention of risk-taking behavior and 18% from a pediatric clinic for families with limited resources. Subjects were consecutively recruited before or after regular clinic visits. Consent was obtained from parents and assent from the youth. High caffeine consumption was associated with daily cigarette use; aggressive behavior; conduct, attention deficit/hyperactivity, and social problems; and increased somatic complaints in adolescents.

OBJECTIVE: This study examined subjective and other behavioral effects of methylphenidate (MPH) among adolescents. METHODS: Standard abuse liability assessment methods that have been used in adult populations were modified for attention-deficit/hyperactivity disorder (ADHD) adolescents. MPH effects (0, 0.25 mg/kg) were evaluated under randomized, double-blind conditions in two 5-hour laboratory sessions in 24 (13 female) 11-15 year olds diagnosed with ADHD. RESULTS: Repeated measures analysis of covariance indicated significant dose and dose by time interactions on subjective ratings on the modified amphetamine (A) [F (1, 20) = 5.98; p < 0.05; eta2 = 0.36], morphine-benzedrine group (MBG) [F (1, 21) = 8.93 p < 0.01; eta2 = 0.38] and benzedrine group scale (BG) [F (1, 21) + 13.10 p < 0.01; eta2 = 0.37] scales of the Addiction Research Center Inventory; "Hungry" and "How sure are you that you got the medication today?" from the Visual Analogue Scale, the Profile of Mood States Depression scale, performance on the Continuous Performance Task, heart rate and blood pressure, and level of activity. CONCLUSIONS: This is the first study to document subjective effects of stimulants in adolescents with ADHD that have been associated with drug abuse potential in adults. There are increasing concerns about nontherapeutic stimulant use in adolescents and young adults. Assessing subjective effects of pharmacotherapies for ADHD along with other measures of abuse potential such as drug self-administration may aid in assessing the therapeutic effects and/or risk of medications used in the treatment of ADHD.

This study was designed to examine the relationship of pubertal changes and sensation seeking (SS) in adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Patients with current or past histories of uncomplicated stimulant medication use for ADHD between the ages of 11 and 15 (13 +/- 1.5) were recruited from a Child Psychiatry and a General Pediatric Clinic. SS was measured using the SS Scale for Children. Pubertal development was measured using Tanner staging, free testosterone, and DHEAS. Subjects and their parent were interviewed with the Diagnostic Interview Schedule for Children (DISC). SS total score was correlated with Tanner stage, free testosterone, and DHEAS (p < or = 0.01). The combined parent and child reports of symptoms of Oppositional Defiant Disorder from the DISC were inversely related to age (p < or = 0.05). Understanding SS in ADHD adolescents as they move through puberty will aid clinicians in monitoring ADHD adolescents and their trajectory into high-risk behaviors.
