Rice, Simon M; Gwyther, Kate; Santesteban-Echarri, Olga; Baron, David; Gorczynski, Paul; Gouttebarge, Vincent; Reardon, Claudia L; Hitchcock, Mary E; Hainline, Brian; Purcell, Rosemary
OBJECTIVE:To identify and quantify determinants of anxiety symptoms and disorders experienced by elite athletes. DESIGN/METHODS:Systematic review and meta-analysis. DATA SOURCES/METHODS:Five online databases (PubMed, SportDiscus, PsycINFO, Scopus and Cochrane) were searched up to November 2018 to identify eligible citations. ELIGIBILITY CRITERIA FOR SELECTING STUDIES/UNASSIGNED:Articles were included if they were published in English, were quantitative studies and measured a symptom-level anxiety outcome in competing or retired athletes at the professional (including professional youth), Olympic or collegiate/university levels. RESULTS AND SUMMARY/UNASSIGNED:=0.26)-higher anxiety in athletes who had experienced one or more recent adverse life events. CONCLUSION/CONCLUSIONS:Determinants of anxiety in elite populations broadly reflect those experienced by the general population. Clinicians should be aware of these general and athlete-specific determinants of anxiety among elite athletes.

Recreational and ergogenic substance use and substance use disorders in elite athletes: a narrative review
McDuff, David; Stull, Todd; Castaldelli-Maia, João Mauricio; Hitchcock, Mary E; Hainline, Brian; Reardon, Claudia L
BACKGROUND:Substances from various classes may be used for recreational purposes, self-treatment or to boost performance. When substance use shifts from occasional to regular, heavy or hazardous use, positive and negative effects can develop that vary by substance class and athlete. Regular use of recreational or performance enhancing substances can lead to misuse, sanctions or use disorders. OBJECTIVE:To review the prevalence, patterns of use, risk factors, performance effects and types of intervention for all classes of recreational and performance enhancing substances in elite athletes by sport, ethnicity, country and gender. METHODS:A comprehensive search was conducted to identify studies that compared the prevalence and patterns of substance use, misuse and use disorders in elite athletes with those of non-athletes and provided detailed demographic and sport variations in reasons for use, risk factors and performance effects for each main substance class. RESULTS:Alcohol, cannabis, tobacco (nicotine) and prescribed opioids and stimulants are the most commonly used substances in elite athletes, but generally used at lower rates than in non-athletes. In contrast, use/misuse rates for binge alcohol, oral tobacco, non-prescription opioids and anabolic-androgenic steroids are higher among athletes than non-athletes, especially in power and collision sports. Cannabis/cannabinoids seem to have replaced nicotine as the second most commonly used substance. CONCLUSIONS:Substance use in elite athletes varies by country, ethnicity, gender, sport and competitive level. There are no studies on substance use disorder prevalence in elite male and female athletes and few studies with direct comparison groups.

Bipolar and psychotic disorders in elite athletes: a narrative review
Currie, Alan; Gorczynski, Paul; Rice, Simon M; Purcell, Rosemary; McAllister-Williams, R Hamish; Hitchcock, Mary E; Hainline, Brian; Reardon, Claudia L
Bipolar and psychotic disorders are relatively common and likely to have a significant impact on quality of life and functioning which, in the context of elite sport, includes a potential negative impact on sporting performance. For this narrative review article, the literature on bipolar and psychotic disorders in elite athletes was comprehensively searched, and little empirical research was found. A diagnosis of bipolar or psychotic disorders may be challenging in elite athletes because of complicating factors related to the modifying role of exercise and potential precipitating impact of substance use. Medications used to treat bipolar and psychotic disorders may have side effects particularly problematic for elite athletes. Future research should be tailored to the specific characteristics and needs of elite athletes and to the sporting context in which the disorders may arise. Specifically, further research is needed on the prevalence and incidence of these conditions in elite athletes and the impact of both the disorders and their treatments on sporting performance.

Attention-deficit/hyperactivity disorder in elite athletes: a narrative review
Han, Doug Hyun; McDuff, David; Thompson, Donald; Hitchcock, Mary E; Reardon, Claudia L; Hainline, Brian
Attention-deficit/hyperactivity disorder (ADHD) is a common brain developmental disorder in the general population that may be even more prevalent in elite athletes in certain sports. General population studies of ADHD are extensive and have reported on prevalence, symptoms, therapeutic and adverse effects of treatment and new clinical and research findings. However, few studies have reported on prevalence, symptoms and treatments of ADHD in elite athletes. This narrative review summarises the literature on symptoms, comorbidities, effects of ADHD on performance and management options for elite athletes with ADHD. The prevalence of ADHD in student athletes and elite athletes may be 7%-8%. The symptoms and characteristics of ADHD play a role in athletes' choice of a sport career and further achieving elite status. Proper management of ADHD in elite athletes is important for safety and performance, and options include pharmacologic and psychosocial treatments.

Wake up call for collegiate athlete sleep: narrative review and consensus recommendations from the NCAA Interassociation Task Force on Sleep and Wellness
Kroshus, Emily; Wagner, Jessica; Wyrick, David; Athey, Amy; Bell, Lydia; Benjamin, Holly J; Grandner, Michael A; Kline, Christopher E; Mohler, Jessica M; Roxanne Prichard, J; Watson, Nathaniel F; Hainline, Brian
Sleep is an important determinant of collegiate athlete health, well-being and performance. However, collegiate athlete social and physical environments are often not conducive to obtaining restorative sleep. Traditionally, sleep has not been a primary focus of collegiate athletic training and is neglected due to competing academic, athletic and social demands. Collegiate athletics departments are well positioned to facilitate better sleep culture for their athletes. Recognising the lack of evidence-based or consensus-based guidelines for sleep management and restorative sleep for collegiate athletes, the National Collegiate Athletic Association hosted a sleep summit in 2017. Members of the Interassociation Task Force on Sleep and Wellness reviewed current data related to collegiate athlete sleep and aimed to develop consensus recommendations on sleep management and restorative sleep using the Delphi method. In this paper, we provide a narrative review of four topics central to collegiate athlete sleep: (1) sleep patterns and disorders among collegiate athletes; (2) sleep and optimal functioning among athletes; (3) screening, tracking and assessment of athlete sleep; and (4) interventions to improve sleep. We also present five consensus recommendations for colleges to improve their athletes' sleep.

Mental health in elite athletes: International Olympic Committee consensus statement (2019)
Reardon, Claudia L; Hainline, Brian; Aron, Cindy Miller; Baron, David; Baum, Antonia L; Bindra, Abhinav; Budgett, Richard; Campriani, Niccolo; Castaldelli-Maia, João Mauricio; Currie, Alan; Derevensky, Jeffrey Lee; Glick, Ira D; Gorczynski, Paul; Gouttebarge, Vincent; Grandner, Michael A; Han, Doug Hyun; McDuff, David; Mountjoy, Margo; Polat, Aslihan; Purcell, Rosemary; Putukian, Margot; Rice, Simon; Sills, Allen; Stull, Todd; Swartz, Leslie; Zhu, Li Jing; Engebretsen, Lars
Mental health symptoms and disorders are common among elite athletes, may have sport related manifestations within this population and impair performance. Mental health cannot be separated from physical health, as evidenced by mental health symptoms and disorders increasing the risk of physical injury and delaying subsequent recovery. There are no evidence or consensus based guidelines for diagnosis and management of mental health symptoms and disorders in elite athletes. Diagnosis must differentiate character traits particular to elite athletes from psychosocial maladaptations.Management strategies should address all contributors to mental health symptoms and consider biopsychosocial factors relevant to athletes to maximise benefit and minimise harm. Management must involve both treatment of affected individual athletes and optimising environments in which all elite athletes train and compete. To advance a more standardised, evidence based approach to mental health symptoms and disorders in elite athletes, an International Olympic Committee Consensus Work Group critically evaluated the current state of science and provided recommendations.

Management of mental health emergencies in elite athletes: a narrative review
Currie, Alan; McDuff, David; Johnston, Allan; Hopley, Phil; Hitchcock, Mary E; Reardon, Claudia L; Hainline, Brian
Mental health emergencies require a rapid, effective response. We searched the literature on mental health emergencies in athletes and found five papers. None of these addressed elite athletes. Nonetheless, common mental health emergencies may present in the sports environment and may place the athlete and others at risk. Sports teams and organisations should anticipate which emergencies are likely and how medical and support staff can best respond. Responses should be based on general non-sporting guidelines. We stress the importance of clinicians following standard procedures.

Problem gambling and associated mental health concerns in elite athletes: a narrative review
Derevensky, Jeffrey Lee; McDuff, David; Reardon, Claudia L; Hainline, Brian; Hitchcock, Mary E; Richard, Jeremie
Opportunities to participate in gambling have dramatically changed during the past 20 years. Casinos have proliferated as have electronic gambling machines, lotteries, sports betting, and most recently online gambling. Gambling among the general population has moved from being perceived negatively to a socially acceptable pastime. As over 80% of individuals have reported gambling for money during their lifetime, governments recognise that regulating gambling-a multibillion dollar industry-is a significant source of revenue. While the vast majority of individuals engaged in some form of gambling have no or few gambling-related problems, an identifiable proportion of both adolescents and adults experience significant gambling-related problems. Elite athletes have not been immune to the lure of gambling nor its concomitant problems. Prevalence studies suggest higher rates of gambling problems among athletes than the general population. In this narrative review, we examine several risk factors associated with gambling problems among elite athletes and new forms of gambling that may be problematic for this population. Given the potential serious mental health and performance consequences associated with a gambling disorder for athletes, we aim to increase coaches', athletic directors' and health professionals' knowledge concerning the importance of screening and treatment referrals.

A cross-species approach to disorders affecting brain and behaviour
Devinsky, Orrin; Boesch, Jordyn M; Cerda-Gonzalez, Sofia; Coffey, Barbara; Davis, Kathryn; Friedman, Daniel; Hainline, Brian; Houpt, Katherine; Lieberman, Daniel; Perry, Pamela; Prüss, Harald; Samuels, Martin A; Small, Gary W; Volk, Holger; Summerfield, Artur; Vite, Charles; Wisniewski, Thomas; Natterson-Horowitz, Barbara
Structural and functional elements of biological systems are highly conserved across vertebrates. Many neurological and psychiatric conditions affect both humans and animals. A cross-species approach to the study of brain and behaviour can advance our understanding of human disorders via the identification of unrecognized natural models of spontaneous disorders, thus revealing novel factors that increase vulnerability or resilience, and via the assessment of potential therapies. Moreover, diagnostic and therapeutic advances in human neurology and psychiatry can often be adapted for veterinary patients. However, clinical and research collaborations between physicians and veterinarians remain limited, leaving this wealth of comparative information largely untapped. Here, we review pain, cognitive decline syndromes, epilepsy, anxiety and compulsions, autoimmune and infectious encephalitides and mismatch disorders across a range of animal species, looking for novel insights with translational potential. This comparative perspective can help generate novel hypotheses, expand and improve clinical trials and identify natural animal models of disease resistance and vulnerability.
