Given the large number of comparisons made, the statistically significant result may be due to chance. At present there is no evidence to recommend its routine use in clinical practice. Although the intention of the review was to access ALC for the treatment of all dementias, the included trials had confined themselves to participants with Alzheimer's disease.

Latest review conclusion

Our findings represent the most comprehensive available evidence base to inform patients, families, clinicians, guideline developers, and policymakers on the choice of ADHD medications across age groups. Taking into account both efficacy and safety, evidence from this meta-analysis supports methylphenidate in children and adolescents, and amphetamines in adults, as preferred first-choice medications for the short-term treatment of ADHD. New research should be funded urgently to assess long-term effects of these drugs.
