Effects of Wheat Bran Extract on Cognitive and Memory Function

Cognitive Function 1, Social Clinical Trial

Official title: Efficacy and Safety of Wheat Bran Extract on Improvement of Cognitive and Memory Function

Status Completed

Clinical Trial Summary

The investigators performed a 12-week, randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of water extract from wheat Triticum aestivum L on cognitive and memory function. The investigators measured changes in cognitive function parameters, including CNT, WMT, K-MMSE, BCRS, PRMQ, PSS, SF-36 and BDNF

Clinical Trial Description

Based on reports about the neuroprotective effects of water extract from wheat Triticum aestivum L. or its bran, the investigators hypothesize that extract of wheat bran (WBE) is beneficial to elderly people with age-associated cognitive impairment. The investigators investigated the efficacy and safety of WBE on improvement of cognitive function through measuring the neuropsychometric assessments in adult with subjective cognitive impairment by a randomized clinical trial.

Seventy participants aged from 50 to 80 years old with subjective cognitive impairment were randomly assigned to receive either WBE (3,000 mg/day) in this 12-week, double-blind placebo-controlled and parallel trial. Neuropsychological assessments including Computerized Neurocognitive function test (CNT), Working Memory Test (WMT), Korean Mini-Mental State Examination (K-MMSE), Brief Cognitive Rating Scale (BCRS), Prospective and Retrospective Memory Questionnaire (PRMQ), Perceived Stress Scale (PSS), 36-Item of Short-Form Health Survey (SF-36) and blood Brain-derived neurotrophic factor (BDNF) were used to assess the cognitive function before and after the intervention. ;
