Phosphatidylserine Containing Omega-3 Fatty Acids May Improve Memory Abilities In Nondemented Elderly Individuals With Memory Complaints: Results From An Open-Label Extension Study

Background: The present study is an open-label extension (OLE) aimed at evaluating the effect of 100 mg/day of phosphatidylserine enriched with docosahexaenoic acid (PS-DHA) on cognitive performance in nondemented elderly individuals with memory complaints. Methods: From the participants who completed the core study, 122 continued with a 15-week OLE. Efficacy was assessed using a computerized tool and the Clinical Global Impression of Change (CGI-C) rating scale. Results: A significant improvement in sustained attention and memory recognition was observed in the PS-DHA naive group, while the PS-DHA continuers maintained their cognitive status. Additionally, a significant improvement in CGI-C was observed in the naive group. Conclusions: The results demonstrate that consumption of 100 mg/day of PS-DHA might be associated with improving or maintaining cognitive status in elderly subjects with memory complaints.
