What the research says

Systematic reviews and meta-analyses from PubMed, with their published conclusions.

BModerate research base

At least one meta-analysis, or 5+ randomized controlled trials. The grade measures how much human research exists — read the conclusions below for what it found.

Cochrane Database Syst Rev · 2005 · Meta-analysis / systematic review
Cytidinediphosphocholine (CDP-choline) for cognitive and behavioural disturbances associated with chronic cerebral disorders in the elderly

Conclusion: There was some evidence that CDP-choline has a positive effect on memory and behaviour in at least the short to medium term. The evidence of benefit from global impression was stronger, but is still limited by the duration of the studies. Further research with CDP-choline should focus on longer term studies in subjects who have been diagnosed with currently accepted standardised criteria, especially Vascular Mild Cognitive Impairment (VaMCI) or vascular dementia.

Cochrane Database Syst Rev · 2004 · Meta-analysis / systematic review
Cytidinediphosphocholine (CDP choline) for cognitive and behavioural disturbances associated with chronic cerebral disorders in the elderly

Conclusion: There is some evidence that CDP Choline has a positive effect on memory and behaviour in at least the short/medium term. The evidence of benefit from global impression is stronger, but is still limited by the duration of the studies. Further research with CDP-choline should focus on longer term studies in subjects who have been diagnosed with currently accepted standardised criteria, especially vascular dementia.

Cochrane Database Syst Rev · 2000 · Meta-analysis / systematic review
Cytidinediphosphocholine (CDP choline) for cognitive and behavioural disturbances associated with chronic cerebral disorders in the elderly

Conclusion: There is some evidence that CDP-choline has a positive effect on memory and behaviour in at least the short term. The evidence of benefit from global impression is stronger, but is still limited by the duration of the studies. There is evidence that the effect of treatment is more homogeneous for patients with cognitive impairment secondary to cerebrovascular disorder. Further studies with a more appropriate length of treatment are recommended owing to the chronic and irreversible nature of the disorders for which this treatment is indicated.
