Life Extension Foundation of Fort Lauderdale, Fla., has announced positive results from its study to assess the effectiveness of the dietary supplement,Cognitex with NeuroProtection Complex, in improving cognitive performance in middle-aged to elderly subjects with subjective memory complaints. In the study, forty middle-aged to elderly subjects were enrolled and dosed with three capsules per day of the dietary supplement. Cognitive evaluations were conducted at various time points with results yielding a score measuring different cognitive capabilities. They assessed the change in cognitive performance from baseline to day 30 and day 60, based on taking the online cognitive assessment tool, computerized neuropsychological test, results from a CGI-I (Clinical Global Impression Improvement) scale, and an assessment survey for consumer attitude. The CGI-I scale provided an overall clinically determined summary measure. Twenty-nine subjects completed the study with no significant adverse events being reported. Preliminary results revealed a statistically significant improvement in three tests. Working Memory-N-Back displayed the most significant improvement (p<0.0001), as well as inspection time and executive function (p<0.05). Based on the CGI-I Scale, improvement was noted after 30 days and 60 days of product dosing.
