Top studies on Active Recall

Ranked by influential-citation count and publication year.

  1. Effects of spermidine supplementation on cognition and biomarkers in older adults with subjective cognitive decline (SmartAge)-study protocol for a randomized controlled trial.

    Alzheimers Res Ther2019n=100Clinical Trial37 influential citations

    Background Given the global increase in the aging population and age-related diseases, the promotion of healthy aging is one of the most crucial public health issues. This trial aims to contribute to the establishment of effective…

  2. Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) 2018 guidelines for the management of patients with bipolar disorder.

    Bipolar disorders2018n=13

    The Canadian Network for Mood and Anxiety Treatments ( CANMAT ) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two…

  3. Frontal theta activity in humans increases with memory load in a working memory task

    European Journal of Neuroscience2002n=10

    Recent theoretical work has suggested that brain oscillations in the theta band are involved in active maintenance and recall of working memory representations. To test this theoretical framework we recorded neuromagnetic responses from 10…

  4. A Cognitive Training Program Based on Principles of Brain Plasticity: Results from the Improvement in Memory with Plasticity‐based Adaptive Cognitive Training (IMPACT) Study

    Journal of the American Geriatrics Society2009n=487

    <h4>Objectives</h4>To investigate the efficacy of a novel brain plasticity-based computerized cognitive training program in older adults and to evaluate the effect on untrained measures of memory and attention and participant-reported…

  5. Efficacy and safety of galantamine in patients with mild to moderate Alzheimer's disease: multicentre randomised controlled trial. Galantamine International-1 Study Group.

    BMJ (Clinical research ed.)2000n=653

    <h4>Objective</h4>To evaluate the efficacy and safety of galantamine in the treatment of Alzheimer's disease.<h4>Design</h4>Randomised, double blind, parallel group, placebo controlled trial.<h4>Setting</h4>86 outpatient clinics in Europe…

  6. Effectiveness of counselling patients on physical activity in general practice: cluster randomised controlled trial

    BMJ2003n=878

    <h4>Objective</h4>To assess the long term effectiveness of the "green prescription" programme, a clinician based initiative in general practice that provides counselling on physical activity.<h4>Design</h4>Cluster randomised controlled…

  7. Remembering the past: two facets of episodic memory explored with positron emission tomography

    American Journal of Psychiatry1995

    <h4>Objective</h4>This study used positron emission tomography to examine two kinds of personal memory that are used in psychiatric evaluation: focused episodic memory (recall of past experience, employed in "taking a history") and random…

  8. Sleep spindles and their significance for declarative memory consolidation.

    Sleep2004n=12

    <h4>Study objectives</h4>Functional significance of stage 2 sleep spindle activity for declarative memory consolidation.<h4>Design</h4>Randomized, within-subject, multicenter.<h4>Setting</h4>Weekly sleep laboratory visits, actigraphy, and…

  9. Study of the ketogenic agent AC-1202 in mild to moderate Alzheimer's disease: a randomized, double-blind, placebo-controlled, multicenter trial.

    Nutrition &amp; metabolism2009n=1,202

    <h4>Background</h4>Alzheimer's disease (AD) is characterized by early and region-specific declines in cerebral glucose metabolism. Ketone bodies are produced by the body during glucose deprivation and are metabolized by the brain. An oral…

  10. A Double-Blind, Randomized, Placebo-Controlled, Dose-Frequency Study of Intravenous Ketamine in Patients With Treatment-Resistant Depression

    American Journal of Psychiatry2016n=45

    <h4>Objective</h4>Ketamine, an N-methyl-d-aspartate glutamate receptor antagonist, has demonstrated a rapid-onset antidepressant effect in patients with treatment-resistant depression. This study evaluated the efficacy of twice- and…

Frequently asked

What dosage was studied?
• Spermidine-based nutritional supplementation (750 mg extract daily, containing 0.9 mg spermidine, 0.5 mg spermine, 0.2 mg putrescine, <0.004 mg cadaverine, and 0.12 mg l-ornithine)
Are there safety considerations for Active Recall?
• Daily dose is stated to be below NOAEL for cadaverine, putrescine, spermidine, spermine, and l-ornithine. • Participants are monitored for AEs and SAEs at 3, 6, and 9 months. • Trial may stop if more than three SAEs are likely related to spermidine. • Emergency unblinding is allowed if needed for medical treatment decisions.
