Effects of a Food Supplement on Cognitive and Neuropsychological Functioning in Older Adults.

A Randomized, Double-blinded, Clinical Trial on Effects of a Food Supplement on Cognitive and Neuropsychological Functioning in Healthy Older Adults.

Mini Mental state Examination is composed of 12 items exploring through 22 trials verbal and performance, 7 cognitive functions: temporal and spatial orientation; immediate memory; attention and calculation; recall memory; language; praxia visuo-constructive.

It is a self-report instrument measuring the severity of depression. The Beck Depression Inventory (BDI) Short Form was used. BDI is a prominently and frequently cited, self-reported measure of depression. The 13-item questionnaire assesses 4 major components of depression: behavioral, affective, cognitive, and physiological. Numerical values assigned to each statement range from 0 to 3 indicating increasing severity. According to Beck's clinical criteria, a score between 8 and 15 indicates moderate depression and 16 severe depression.

Hamilton Anxiety Rating Scale is a scale evaluating anxiety through the investigation of 15 different areas (such as insomnia, mood, somatic symptoms). Each of the 15 areas is composed of a minimum of 3 to a maximum of 8 items to each of which is given a score from 0 to 6, depending on the severity of symptoms. Subsequently the total value is calculated for each area, using a score of 0 (absent), 1 (mild), 2 (moderate), 3 (severe), or 4 (very severe) points, based on the overall severity of symptoms investigating each specific area. The total score, which has been called "whole", is calculated by adding the points of each of the 15 areas surveyed. The rating of the scale may vary from 0 to 56. A total score around 18 is considered indicative of a pathological state.

Repeatable Battery for the Assessment of Neuropsychological Status is a quick and complete neuropsychological battery, consisting of two forms ( "A" and "B") associated with identical difficulty degrees, each divided into 12 subtests administered to evaluate 5 different cognitive domains: attention, language, visuospatial/constructional abilities immediate memory and delayed memory.

Randomized, double-blinded, placebo controlled study.

subjects were randomly allocated to one of two groups treated as follows: Group 1, N = 57 to be treated with Cognigrape capsule (verum 250 mg/day); Group 2, N = 54 to be treated with placebo for 12 weeks. Neither subjects recruited for the study nor investigators knew the content of sachets or were able to differentiate the two different treatments.

Compare the polysomnography of participants with insomnia on a night at the end of 2 weeks taking: Eight ounces of standardized cherry juice vs. the night taking the placebo juice.

Compare the Insomnia Severity Index, a validated questionnaire, in participants with insomnia on a night at the end of 2 weeks taking: 1. Eight ounces of cherry juice standardized to its proanthocyanidin content in the morning, and 1-2 hours before bedtime; 2. Eight ounces of an identical appearing placebo in the morning and 1-2 hours before bedtime.

Compare five different sleep quality scales with insomnia on a night at the end of 2 weeks taking: 1. An 8-ounce glass of cherry juice standardized to its proanthocyanidin content in the morning and 1-2 hours before bedtime; 2. an 8- ounce glass of an identical appearing placebo in the morning and 1-2 hours before bedtime.
