Effects of Astaxanthin in patients with memory impairment

Summary/Abstract: Introduction: Astaxanthin is used to treat a variety of cardiovascular, metabolic, ophthalmological, immune, degenerative, and psychiatric disorders. We aimed to perform a systematic review on the effects of astaxanthin in people with mental disorders. Material and method: Several medical databases were searched: PubMed, Embase, Cochrane, PMC to identify randomized studies for both humans and animals on the effects of this antioxidant on cognitive function. Results and discussions: Analyzed studies show that Astaxanthin is a carotenoid with strong antioxidant properties. It is useful as a supplement for the positive effects on the health of the cardiovascular system, immunity, but also on mental health. Due to the fact that Astaxanthin can cross the blood-brain barrier, it plays a very important role in everything related to the activity of the brain, protecting the nervous system from the harmful effects of the oxidative stress. Astaxanthin has direct effects on memory disorders present in young people as well as in the elderly, improving memory and ability to concentrate. Conclusions: This review of the data showed that astaxanthin has direct effects on the risk factors that trigger memory disorders. It reduces the risk of developing cardiovascular disease, but also protects directly and indirectly the activity of the brain, diminishing the harmfull effects of the oxidative stress on the nervous system. It is a very useful natural supplement for memory disorders, helping mental health by improving cognitive function. Further studies are needed to better understand the effects of astaxanthin on all human memory disorders, but it has been shown to improve memory and the ability to concentrate. Astaxanthin could be useful in treating Alzheimer's disease, Parkinson and for reducing the consquencies of stroke.
