Practice GuidelineEvidence-based guidelines for management of attention-deficit/hyperactivity disorder in adolescents in transition to adult services and in adults: recommendations from the British Association for Psychopharmacology.
Attention-deficit/hyperactivity disorder (ADHD) is an established diagnosis in children, associated with a large body of evidence on the benefits of treatment. Adolescents with ADHD are now leaving children's services often with no readily identifiable adult service to support them, which presents problems as local pharmacy regulations often preclude the prescription of stimulant drugs by general practitioners (GPs). ⋯ Much of this initial guidance on managing ADHD in adolescents in transition and in adults is based on expert opinion derived from childhood evidence. We hope that, by the time these guidelines are updated, much evidence will be available to address the many directions for future research that are detailed here.

Case ReportsAripiprazole use in individuals with intellectual disability and psychotic or behavioural disorders: a case series.
People with intellectual disabilities may be at greater risk of developing movement disorders as a consequence of their underlying neurological damage, especially when they are treated with typical antipsychotic agents. Aripiprazole is a novel antipsychotic quinolone derivative that has been approved for the treatment of schizophrenia in adults. However, there are few reports on the use of aripiprazole in people with intellectual disabilities. ⋯ Issues related to the usefulness of aripiprazole in the management of schizophrenia and challenging behaviour in people with intellectual disabilities are also discussed. Aripiprazole was well tolerated and effective in each of the cases and appears to be a safe and efficacious alternative in the management of patients with both intellectual disabilities and schizophrenia. It can also be a useful treatment option in the management of challenging behaviour, especially when it is used as a part of a biopsychosocial approach.

Memory deficits in abstinent MDMA (ecstasy) users: neuropsychological evidence of frontal dysfunction.
Chronic administration of the common club drug 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is associated with long-term depletion of serotonin (5-HT) and loss of 5-HT axons in the brains of rodents and non-human primates, and evidence suggests that recreational MDMA consumption may also affect the human serotonergic system. Moreover, it was consistently shown that abstinent MDMA users have memory deficits. Recently, it was supposed that these deficits are an expression of a temporal or rather hippocampal dysfunction caused by the serotonergic neurotoxicity of MDMA. ⋯ In addition, they also showed a worse recall consistency and strong retroactive interference whereby both measures were previously associated with frontal lobe function. There was a significant correlation between memory performance and the amount of MDMA taken. These results suggest that the memory deficits of MDMA users are not only the result of a temporal or hippocampal dysfunction, but also of a dysfunction of regions within the frontal cortex.

Meta Analysis Comparative StudyThe impact of atypical antipsychotic medications on long-term memory dysfunction in schizophrenia spectrum disorder: a quantitative review.
This meta-analytic review examines the efficacy of antipsychotic medications in ameliorating schizophrenia-related long-term memory (LTM) impairments. Twenty-three studies were reviewed that compared schizophrenia spectrum patients treated (a) with atypical versus typical antipsychotic medications, or (b) with various atypical treatments. In 17 atypical versus typical trials aggregating 939 participants, superior overall (verbal and nonverbal) LTM was detected in patients assigned to atypical trials. ⋯ Direct comparison between atypical trials revealed a similar effect pattern. A marginally significant superiority in overall LTM was detected for risperidone and olanzapine compared to clozapine (ES 0.28; 95% CI -0.04 to 0.59), which reached significance for verbal LTM (ES 0.36; 95% CI 0.04 to 0.67). Finally, the beneficial impact of antipsychotic medications emerged as a function of differences in the anticholinergic properties of the treatment arms being compared.

ReviewThe confounding problem of polydrug use in recreational ecstasy/MDMA users: a brief overview.
The popular dance drug ecstasy (3,4-methylenedioxymethamphetamine -- MDMA) is neurotoxic upon central serotonergic neurons in laboratory animals and possibly also in humans. In recent years, several studies reported alterations of serotonergic transmission and neuropsychiatric abnormalities in ecstasy users which might be related to MDMA-induced neurotoxic brain damage. To date, the most consistent findings associate subtle cognitive, particularly memory, deficits with heavy ecstasy use. ⋯ The interactions between MDMA and cannabis use may be more complex: cannabis use is a well-recognized risk factor for neuropsychiatric disorders and it was shown to contribute to psychological problems and cognitive failures in ecstasy users. However, at the cellular level, cannabinoids have neuroprotective actions and they were shown to (partially) block MDMA-induced neurotoxicity in laboratory animals. In future, longitudinal and prospective research designs should hopefully lead to a better understanding of the relation between drug use and subclinical psychological symptoms or neurocognitive failures and, also, of questions around interactions between the various substances of abuse.
