Adderall: On the Razor's Edge of ADHD Treatment, Enhanced Academic and Physical Performance, Addiction, Psychosis, and Death

Authors:

Abstract

Adderall, as a drug combination, is medically-approved for treating attention-deficit/hyperactivity disorder (ADHD) and nar-colepsy. The active ingredients of Adderall are central nervous system stimulants, affecting neurotransmitters and promoting the synthesis of specific neuropeptides. Pharmacological effects include increased physical energy, improved mental aptitude, hyperex-citability, and mood elevation. In ADHD, Adderall increases arousal, wakefulness, and motivation to execute a task, promoting goal-directed behavior. Regarding physical performance, amphetamine (Adderall) improves endurance and reaction time. Thus, Adderall is banned for use among professional and Olympic athletes. As well as benefits, Adderall has numerous mild to severe adverse effects (including death) and can result in physical and psychological dependence. The sudden cessation of the drug may cause paranoid delusion, psychosis, hallucinations, mood swings, suicidal ideation, panic attack, and tremor. Also, long-term use can result in tolerance to the drug. Adderall has high abuse potential as a recreational agent. It is misused as an academic-enhancer-known as "smart pills"-by students. Although medically-approved for managing symptoms of ADHD and in treating narcolepsy, Adderall has a high abuse and addiction potential and should be taken only if medically prescribed. Realistically, however, Adderall's off-label and unpre-scribed use will likely continue; if so, it should be taken with extreme caution and vigilance.

amphetamine can impair working memory and diminish cognitive abilities [8,12].
Spencer., et al. (2015) reviewed currently available evidence on amphetamine and found that the drug improved cognition, working
memory, long-term episodic memory, inhibitory control, and attention span in normal, otherwise healthy individuals [7]. They reported

Pharmacological effects: physical performance
Amphetamine improves endurance and reaction time, primarily through reuptake inhibition and the release of dopamine in the CNS
[14,15]. Amphetamine and other dopaminergic drugs improve power output by facilitating a rise in the core body temperature by over-
riding the feedback inhibition process (“safety switch”) that occurs under normal physiological conditions [15,16].
At a therapeutic dose range, amphetamine does not decrease athletic performance, but a higher dose can cause an increase in body
temperature and a rapid breakdown of muscle mass [10]. Thus, amphetamine use is prohibited (unless indicated medically) for athletes
participating in any sporting event, and different national and international authorities regulate or prohibit its use [17].

potential in improving performance. Amphetamine improves anaerobic performance with a modest effect on aerobic performance. Pub-
lished studies reveal that amphetamine improves the reaction time, especially when the athlete is fatigued, increases muscle strength and
endurance, facilitates metabolism by stimulating fat metabolism, and increases endurance. However, at higher doses, the drug tends to
promote aggressiveness. Amphetamine in healthy individuals was reported to increase muscle strength, acceleration, alertness, athletic
performance under anaerobic circumstances, and reaction time and delays the onset of fatigue [14,15].

ciation (NBA), National Collegiate Athletic Association (NCAA), International Olympic Committee (IOC), and World Anti-Doping Agency
(WADA) have banned the use of Adderall among athletes participating in sporting events [17,19]. The athletes are screened daily for the
presence of prohibited substances, including amphetamine, by accredited laboratories. In competitive sports, amphetamine comes under
Category S6, and its presence in urine is considered a severe doping offense [18].

accident (stroke) may occur [21,22]. Adderall (amphetamine) can produce both physical and psychological dependence. Thus, sudden
cessation of the drug may cause withdrawal syndrome characterized by paranoid delusion, psychosis, hallucinations, mood swings, sui-
cidal ideation, panic attack, and tremor [20,23].

Adverse effects in long-term use
Prolonged use of amphetamine causes patients to develop tolerance to the drug. It may also cause physical dependence, often leading
to severe withdrawal symptoms [27]. Amphetamine-dependent individuals demonstrate signs of increased aggression, psychosis, and
anti-social behavior [26].

prescribed at low doses, which is increased gradually based on the response and tolerability [3].

ADHD and prescribed Adderall or similar drugs in 2015 [26]. However, the massive surge in such prescriptions has led to increased ad-
diction to these drugs.
Conclusion
Adderall is medically-approved for managing symptoms of ADHD and treating narcolepsy. However, it has abuse potential as it en-
hances cognitive and physical performance. Adderall is misused as a recreational drug, academic-enhancer (“smart pills”) by students,
and performance-enhancer by athletes.
Long-term Adderall use and short-term use at higher doses result in mild to severe adverse effects, such as increased blood pressure,
elevated core body temperature, precipitation of psychosis, hallucination, delirium, aggression, suicidal ideation, and insomnia. Although

resulting in death.
Several international and national regulatory bodies have prohibited the use of Adderall among athletes participating in sporting

Amphetamine abuse is a major public health concern for which there is currently no effective treatment. To develop effective treatments, the mechanisms by which amphetamine produces its abuse-related effects need to be fully understood. It is well known that amphetamine exerts its actions by targeting high-affinity transporters for monoamines, in particular the cocaine-sensitive dopamine transporter. Organic cation transporter 3 (OCT3) has recently been found to play an important role in regulating monoamine signaling. However, whether OCT3 contributes to the actions of amphetamine is unclear. We found that OCT3 is expressed in dopamine neurons. Then, applying a combination of in vivo, ex vivo, and in vitro approaches, we revealed that a substantial component of amphetamine’s actions is OCT3-dependent and cocaine insensitive. Our findings support OCT3 as a new player in the actions of amphetamine and encourage investigation of this transporter as a potential new target for the treatment of psychostimulant abuse.

Amphetamine abuse is a global problem. The cardiotoxic manifestations like acute myocardial infarction (AMI), heart failure, or arrhythmia related to misuse of amphetamine and its synthetic derivatives have been documented but are rather rare. Amphetamine-related AMI is even rarer. We report two cases of men who came to emergency department (ED) with chest pain, palpitation, or seizure and were subsequently found to have myocardial infarction associated with the use of amphetamines. It is crucial that, with increase in amphetamine abuse, clinicians are aware of this potentially dire complication. Patients with low to intermediate risk for coronary artery disease with atypical presentation may benefit from obtaining detailed substance abuse history and urine drug screen if deemed necessary.

The amphetamine analogue 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’) is widely abused as a recreational drug due to its unique psychological effects. Of interest, MDMA causes long-lasting deficits in neurochemical and histological markers of the serotonergic neurons in the brain of different animal species. Such deficits include the decline in the activity of tryptophan hydroxylase in parallel with the loss of 5-HT and its main metabolite 5-hydoxyindoleacetic acid (5-HIAA) along with a lower binding of specific ligands to the 5-HT transporters (SERT). Of concern, reduced 5-HIAA levels in the CSF and SERT density have also been reported in human ecstasy users, what has been interpreted to reflect the loss of serotonergic fibers and terminals. The neurotoxic potential of MDMA has been questioned in recent years based on studies that failed to show the loss of the SERT protein by western blot or the lack of reactive astrogliosis after MDMA exposure. In addition, MDMA produces a long-lasting down-regulation of SERT gene expression; which, on the whole, has been used to invoke neuromodulatory mechanisms as an explanation to MDMA-induced 5-HT deficits. While decreased protein levels do not necessarily reflect neurodegeneration, the opposite is also true, that is, neuroregulatory mechanisms do not preclude the existence of 5-HT terminal degeneration.

Psychostimulants are highly effective in the treatment of attention deficit hyperactivity disorder (ADHD). The clinical efficacy of these drugs is strongly linked to their ability to improve cognition dependent on the prefrontal cortex (PFC) and extended frontostriatal circuit. The procognitive actions of psychostimulants are only associated with low doses. Surprisingly, despite nearly 80 years of clinical use, the neurobiology of the procognitive actions of psychostimulants has only recently been systematically investigated. Findings from this research unambiguously demonstrate that the cognition-enhancing effects of psychostimulants involve the preferential elevation of catecholamines in the PFC and the subsequent activation of norepinephrine α2- and dopamine D1 receptors. In contrast, while the striatum is a critical participant in ‘PFC-dependent’ cognition, where examined, psychostimulant action within the striatum is not sufficient to enhance cognition. At doses that moderately exceed the clinical range, psychostimulants appear to improve PFC-dependent attentional processes at the expense of other PFC-dependent processes (e.g. working memory, response inhibition). This differential modulation of PFC-dependent processes across dose appears to be associated with the differential involvement of noradrenergic α2 vs. α1 receptors. Collectively, this evidence indicates that at low, clinically-relevant doses, psychostimulants are devoid of the behavioral and neurochemical actions that define this class of drugs and instead act largely as cognitive enhancers (improving PFC-dependent function). This information has potentially important clinical implications as well as relevance for public health policy regarding the widespread clinical use of psychostimulants and for the development of novel pharmacological treatments for ADHD and other conditions associated with PFC dysregulation.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity that cause functional impairment. Recent research indicates that symptoms persist into adulthood in the majority of cases, with prevalence estimates of approximately 5% in the school age population and 2.5%–4% in the adult population. Although students with ADHD are at greater risk for academic underachievement and psychosocial problems, increasing numbers of students with ADHD are graduating from high school and pursuing higher education. Stimulant medications are considered the first line of pharmacotherapy for individuals with ADHD, including college students. Although preliminary evidence indicates that prescription stimulants are safe and effective for college students with ADHD when used as prescribed, very few controlled studies have been conducted concerning the efficacy of prescription stimulants with college students. In addition, misuse of prescription stimulants has become a serious problem on college campuses across the US and has been recently documented in other countries as well. The purpose of the present systematic review was to investigate the efficacy of prescription stimulants for adolescents and young adults with ADHD and the nonmedical use and misuse of prescription stimulants. Results revealed that both prostimulant and stimulant medications, including lisdexamfetamine dimesylate, methylphenidate, amphetamines, and mixed-amphetamine salts, are effective at reducing ADHD symptoms in adolescents and adults with ADHD. Findings also suggest that individuals with ADHD may have higher rates of stimulant misuse than individuals without the disorder, and characteristics such as sex, race, use of illicit drugs, and academic performance are associated with misuse of stimulant medications. Results also indicate that individuals both with and without ADHD are more likely to misuse short-acting agents than long-acting agents. These findings have implications for intervention, prevention, and future research.

Psychostimulants such as cocaine have been used as performance enhancers throughout recorded history. Although psychostimulants are commonly prescribed to improve attention and cognition, a great deal of literature has described their ability to induce cognitive deficits, as well as addiction. How can a single drug class be known to produce both cognitive enhancement and impairment? Properties of the particular stimulant drug itself and individual differences between users have both been suggested to dictate the outcome of stimulant use. A more parsimonious alternative, which we endorse, is that dose is the critical determining factor in cognitive effects of stimulant drugs. Herein, we review several popular stimulants (cocaine, amphetamine, methylphenidate, modafinil, and caffeine), outlining their history of use, mechanism of action, and use and abuse today. One common graphic depiction of the cognitive effects of psychostimulants is an inverted U-shaped dose-effect curve. Moderate arousal is beneficial to cognition, whereas too much activation leads to cognitive impairment. In parallel to this schematic, we propose a continuum of psychostimulant activation that covers the transition from one drug effect to another as stimulant intake is increased. Low doses of stimulants effect increased arousal, attention, and cognitive enhancement; moderate doses can lead to feelings of euphoria and power, as well as addiction and cognitive impairment; and very high doses lead to psychosis and circulatory collapse. This continuum helps account for the seemingly disparate effects of stimulant drugs, with the same drug being associated with cognitive enhancement and impairment.

Amphetamine was discovered over 100 years ago. Since then, it has transformed from a drug that was freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy. This review describes the relationship between chemical structure and pharmacology of amphetamine and its congeners. Amphetamine's diverse pharmacological actions translate not only into therapeutic efficacy, but also into the production of adverse events and liability for recreational abuse. Accordingly, the balance of benefit/risk is the key challenge for its clinical use. The review charts advances in pharmaceutical development from the introduction of once-daily formulations of amphetamine through to lisdexamfetamine, which is the first d-amphetamine prodrug approved for the management of ADHD in children, adolescents and adults. The unusual metabolic route for lisdexamfetamine to deliver d-amphetamine makes an important contribution to its pharmacology. How lisdexamfetamine's distinctive pharmacokinetic/pharmacodynamic profile translates into sustained efficacy as a treatment for ADHD and its reduced potential for recreational abuse is also discussed.

Fatigue during prolonged exercise is often described as an acute impairment of exercise performance that leads to an inability to produce or maintain a desired power output. In the past few decades, interest in how athletes experience fatigue during competition has grown enormously. Research has evolved from a dominant focus on peripheral causes of fatigue towards a complex interplay between peripheral and central limitations of performance. Apparently, both feedforward and feedback mechanisms, based on the principle of teleoanticipation, regulate power output (e.g. speed) during a performance. This concept is called ‘pacing’ and represents the use of energetic resources during exercise, in a way such that all energy stores are used before finishing a race, but not so far from the end of a race that a meaningful slowdown can occur. It is believed that the pacing selected by athletes is largely dependent on the anticipated exercise duration and on the presence of an experientially developed performance template. Most studies investigating pacing during prolonged exercise in ambient temperatures, have observed a fast start, followed by an even pace strategy in the middle of the event with an end sprint in the final minutes of the race. A reduction in pace observed at commencement of the event is often more evident during exercise in hot environmental conditions. Further, reductions in power output and muscle activation occur before critical core temperatures are reached, indicating that subjects can anticipate the exercise intensity and heat stress they will be exposed to, resulting in a tactical adjustment of the power output. Recent research has shown that not only climatic stress but also pharmacological manipulation of the central nervous system has the ability to cause changes in endurance performance. Subjects seem to adapt their strategy specifically in the early phases of an exercise task. In high-ambient temperatures, dopaminergic manipulations clearly improve performance. The distribution of the power output reveals that after dopamine reuptake inhibition, subjects are able to maintain a higher power output compared with placebo. Manipulations of serotonin and, especially, noradrenaline, have the opposite effect and force subjects to decrease power output early in the time trial. Interestingly, after manipulation of brain serotonin, subjects are often unable to perform an end sprint, indicating an absence of a reserve capacity or motivation to increase power output. Taken together, it appears that many factors, such as ambient conditions and manipulation of brain neurotransmitters, have the potential to influence power output during exercise, and might thus be involved as regulatory mechanisms in the complex skill of pacing.

Increasing prescription stimulant abuse among youth without diagnoses of attention deficit hyperactivity disorder (ADHD) is of concern. The most frequently cited motive for abuse is improved academic achievement via neurocognitive enhancement. Our aim in reviewing the literature was to identify neurocognitive effects of prescription stimulants in non-ADHD youth. A systematic review was conducted for youth aged 12–25 years using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fourteen papers were included. Modafinil appears to improve reaction time (P ≤ 0.04), logical reasoning (P ≤ 0.05) and problem-solving. Methylphenidate appears to improve performance in novel tasks and attention-based tasks (P ≤ 0.05), and reduces planning latency in more complex tasks (P ≤ 0.05). Amphetamine has been shown to improve consolidation of information (0.02 ≥ P ≤ 0.05), leading to improved recall. Across all three types of prescription stimulants, research shows improved attention with lack of consensus on whether these improvements are limited to simple versus complex tasks in varying youth populations. The heterogeneity of the non-attention deficit hyperactivity disorder youth population, the variation in cognitive task characteristics and lack of replication of studies makes assessing the potential global neurocognitive benefits of stimulants among non-attention deficit hyperactivity disorder youth difficult; however, some youth may derive benefit in specific cognitive domains.
