Conclusion: Citicoline adjuvant therapy has beneficial effects as an adjuvant therapy in patients with PD. However, due to the heterogeneity of the studies, there is a need for more high-quality studies.

What the research says
Systematic reviews and meta-analyses from PubMed, with their published conclusions.
3+ meta-analyses or systematic reviews and 10+ randomized controlled trials in humans. The grade measures how much human research exists — read the conclusions below for what it found.
Conclusion: Citicoline clinical efficacy trials are now continuing outside of the US in both ischemic and hemorrhagic stroke. A citicoline supplement is now available from several sources on the internet.
PubMed 19351232 ↗Conclusion: This systematic review supports some benefits of citicoline in the treatment of acute ischemic stroke. But, on top of the best treatment available (rtPA), citicoline offers a limited benefit.
PubMed 27234918 ↗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.
