Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT03954899). This is a study registration, not published results. Lead sponsor: Natalie Denburg. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 230 participants (ESTIMATED). Conditions: Mild Cognitive Impairment, Cognitive Decline, Healthy Aging. Interventions: DIETARY_SUPPLEMENT: melatonin; OTHER: placebo. Primary outcome measures: Episodic memory , Assessed at pre-treatment (week-8), and two post-treatment occasions: week-16 and week-44.. Brief summary: The study will examine whether 5mg melatonin (over the counter, OTC) over a 9-month period improves Alzheimer's disease (AD) biomarkers and cognitive function in two groups of individuals: those with mild cognitive impairment (MCI+) and those who are not (MCI-). AD biomarkers will be measured from cerebrospinal fluid (CSF) obtained from lumbar punctures. Cognitive function will be evaluated with routine neuropsychological tests. AS OF AUGUST 2024, THE LUMBAR PUNCTURE PROCEDURES FOR THIS CLINICAL TRIAL HAVE BEEN ELIMINATED. THAT IS, PARTICIPANTS ARE NO LONGER RECEIVING A LUMBER PUNCTURE. BUT ARE CONTINUING TO RECEIVE TWO SEPARATE BLOOD DRAWS FOR BIOMARKER TESTING.
