ABSTRACT To test whether children with attention-deficit/hyperactivity disorder (ADHD), free of conduct disorder (CD) in childhood (mean = 8 years), have elevated risk-taking, accidents, and medical illnesses in adulthood (mean = 41 years); whether development of CD influences risk-taking during adulthood; and whether exposure to psychostimulants in childhood predicts cardiovascular disease. We hypothesized positive relationships between childhood ADHD and risky driving (in the past 5 years), risky sex (in the past year), and between risk-taking and medical conditions in adulthood; and that development of CD/antisocial personality (APD) would account for the link between ADHD and risk-taking. We report causes of death.
Prospective 33-year follow-up of 135 boys of white ethnicity with ADHD in childhood and without CD (probands), and 136 matched male comparison subjects without ADHD (comparison subjects; mean = 41 years), blindly interviewed by clinicians.
In adulthood, probands had relatively more risky driving, sexually transmitted disease, head injury, and emergency department admissions (p< .05-.01). Groups did not differ on other medical outcomes. Lifetime risk-taking was associated with negative health outcomes (p = .01-.001). Development of CD/APD accounted for the relationship between ADHD and risk-taking. Probands without CD/APD did not differ from comparison subjects in lifetime risky behaviors. Psychostimulant treatment did not predict cardiac illness (p = .55). Probands had more deaths not related to specific medical conditions (p = .01).
Overall, among children with ADHD, it is those who develop CD/APD who have elevated risky behaviors as adults. Over their lifetime, those who did not develop CD/APD did not differ from comparison subjects in risk-taking behaviors. Findings also provide support for long-term safety of early psychostimulant treatment.

    ABSTRACT: Attention-deficit hyperactivity disorder (ADHD) is a heterogeneous psychiatric disorder affecting 5–10% of children. One of the suggested mechanisms underlying the pathophysiology of ADHD is insufficient energy supply to neurons. Here, we investigated the role of omega 3 fatty acids in altering neural energy metabolism and behavior of spontaneously hypertensive rats (SHR), which is an animal model of ADHD. To this end, we employed Proton Magnetic Resonance Spectroscopy (1H MRS) to evaluate changes in brain neurochemistry in the SHR following consumption of one of three experimental diets (starting PND 21): fish oil enriched (FOE), regular (RD) and animal fat enriched (AFE) diet. Behavioral tests were performed to evaluate differences in locomotor activity and risk-taking behavior (starting PND 44). Comparison of frontal lobe metabolites showed that increased amounts of omega 3 fatty acids decreased total Creatine levels (tCr), but did not change Glutamate (Glu), total N-Acetylaspartate (tNAA), Lactate (Lac), Choline (Cho) or Inositol (Ino) levels. Although behavior was not significantly affected by different diets, significant correlations were observed between brain metabolites and behavior in the open field and elevated plus maze. SHR with higher levels of brain tCr and Glu exhibited greater hyperactivity in a familiar environment. On the other hand, risk-taking exploration of the elevated plus maze's open arms correlated negatively with forebrain tNAA and Lac levels. These findings support the possible alteration in energy metabolites in ADHD, correlating with hyperactivity in the animal model. The data also suggest that omega 3 fatty acids alter brain energy and phospholipid metabolism.

    ABSTRACT: Little is known about the relation between entrepreneurship and the extent of psychiatric symptoms. Validated psychiatric symptom scores are seldom used for non-clinical reasons. One prevalent symptom that deserves our interest is Attention Deficit and Hyperactivity Disorder (ADHD). ADHD is a developmental disorder characterized by inattentiveness and hyperactivity that has been linked to occupational choice and performance. Building on the person–environment fit literature, we hypothesize that individuals who exhibit behavior associated with ADHD are more likely to have entrepreneurial intentions. Using a sample of 10,104 students enrolled in higher education, we can confirm our prediction that students with a higher level of ADHD-like behavior are more likely to have entrepreneurial intentions. Additionally, we show that risk taking propensity is a mediator that partly explains this positive effect. Our study points to the importance of behavioral tendencies associated with developmental disorders, when making entrepreneurship decisions. Our study contributes to the literature on the determinants of entrepreneurship, which so far has largely neglected the effects of psychiatric symptoms on entrepreneurship.

    ABSTRACT: Objective: This study investigated the association between mild traumatic brain injury (mTBI) and ADHD, which increases risk of injuries and accidents. Method: We conducted a systematic review and meta-analysis of studies that examined the relationship between mTBI and ADHD. Results: Five studies, comprising 3,023 mTBI patients and 9,716 controls, fit our a priori inclusion and exclusion criteria. A meta-analysis found a significant association between ADHD and mTBI, which was significant when limited to studies that reported on ADHD subsequent to mTBI and when the direction of the association was not specified, but not for studies that reported mTBI subsequent to ADHD. Heterogeneity of effect size and publication biases were not evident. Conclusion: The literature documents a significant association between mTBI and ADHD. Further clarification of the relationship and direction of effect between mTBI and ADHD and treatment implications could have large clinical, scientific, and public health implications.
