Medications known as 'cognitive enhancers' are increasingly being consumed off-label by healthy people, raising concerns about their safety. The aim of our study was to profile behavioral performance upon oral administration of methylphenidate (2.5 mg/kg) and modafinil (64 mg/kg) - two popular cognitive enhancers - and upon their discontinuation.

The purpose of this trial was to assess the effects of methylphenidate on the kidney tissues and to investigate the protective effect of adenosine triphosphate (ATP) against possible methylphenidate nephrotoxicity in rats. The rats were separated into; healthy control (HG), methylphenidate (MPHG), ATP (ATPG), and ATP+ methylphenidate (AMPG). The ATPG and AMPG groups were administered ATP 4 mg/kg bw/d, and the HG and MPHG groups received distilled water intraperitoneally.

Objective: Stimulant medications are the primary pharmacological intervention for ADHD, yet our understanding of how sex and gender impact stimulant treatment outcomes remains limited. Clinical guidelines do not differ for female and male individuals despite possible sex and gender-related differences in effectiveness, adverse events, and pharmacokinetics. This theoretical framework identifies five key knowledge gaps relating to sex and gender effects in stimulant treatment.

Background: Raynaud syndrome (RS) is a peripheral vasculopathy characterised be impaired acral perfusion typically manifesting as skin discolouration with pallor, cyanosis and/or erythema, and increased sensitivity to cold. RS may be primary or secondary to systemic disease, lifestyle and environmental factors or medication. RS has been reported with medication to treat ADHD, but we found no recent comprehensive overview of the literature.

Under rapid-acquisition, concurrent-chains choice procedures, psychomotor stimulants typically decrease the sensitivity of responding to changes in separate dimensions of reinforcement. Across two experiments, pigeons chose between outcomes that differed in terms of reinforcement delay and magnitude (the dimensions involved in delay discounting or "impulsive" choice; Experiment 1) or reinforcement probability and magnitude (the dimensions involved in probability discounting or "risky" choice; Experiment 2). Outcomes associated with each terminal link were varied independently and pseudorandomly across sessions such that in dominated sessions one terminal link was favorable in terms of both dimensions (sooner, larger in Experiment 1 and more likely, larger in Experiment 2) and in trade-off sessions each terminal link was favorable in terms of a different dimension.
