About this study

Official title: Nutriceutical Effects on Cognitive Status in Mild Cognitive Impairment Patients

A vitamin nutriceutical, Memory XL, has been shown to provide maintenance of cognitive status in mild, moderate, and severe Alzheimer's disease patients (2 publications by T. Shea). Because this nutriceutical is now patented by the Univ. of Mass., other trials at that institution may be considered a conflict of interest. Therefore, a study of its effects on Mild Cognitive Impairment (MCI) patients will be conducted by PI who is not affiliated with Univ. of Mass. or with Dr. Shea. The study hypothesis is: Memory XL will maintain or improve the cognitive and behavioral status of patients diagnosed with MCI during the year of participation in the study; normally, 10-25% of MCI patients convert to mild Alzheimer's dementia each year.

Read the detailed description

This IRB-approved study is a randomized double blind study of patients diagnosed with Mild Cognitive Impairment (MCI) in the Center for Alzheimer's and Neurodegenerative Disorders (CANDO) at VAMC in Oklahoma City. Dr. Shea provided the pills (nutriceutical and placebos) from the same batches he used in former studies of Alzheimer's disease patients (produced by Nutricap Labs, Farmingdale, NY). Pills were dispensed by the OKC VAMC research pharmacist, using a random numbering system. The PI completed five cognitive testing sessions, lasting 1 to 1.5 hours, for each subject during the 12 months of participation in the study. Subject's spouse or family member completed 4 questionnaires about the subject's behavioral changes, and kept daily records of the times each day when the subject ingested the study pill assigned by the pharmacist. All subjects are patients in the VAMC memory loss clinic (CANDO) who are monitored by their neurologists (2 co-investigators in this study).

Study groups in NCT00903695
Study groupRoleWhat they receive
Memory XLExperimentalSubjects will take 2 Memory XL pills daily for 12 months (a vitamin nutriceutical developed by Thomas Shea, Ph.D.). Mild Cognitive Impairment (MCI) patients, who met inclusion/exclusion criteria, were assessed initially using 3 cognitive tests and 4 behavioral questionnaires, before they began ingesting pills assigned to them by VAMC Research Pharmacist. Each 3 months thereafter, they returned to lab to be reassessed using same instruments, and to receive the next batch of study pills from the Pharmacist. The last assessment was when the patient had just finished 12 months of pill ingestion.
Receives: Drug: Memory XL
placeboPlacebo comparatorSubjects diagnosed with MCI took two placebo pills daily for 12 months; these pills are formulated to look and taste the same as the nutriceutical being studied, Memory XL, so study was double-blind. Procedures for this arm are exactly the same as the MEMORY XL arm. MCI subjects were assessed using 3 cognitive tests and 4 behavioral questionnaires, before they began ingesting the pills assigned to them by the Research Pharmacist at VAMC. Each 3 months thereafter, they returned to lab to be reassessed using the same instruments, and to receive next batch of study pills. Last assessment was when patient had completed 12 months of pill ingestion.
Receives: Drug: placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Differences in Dementia Rating Scale (DRS) at 12 Months From Baseline, by Study Group

    Dementia Rating Scale (DRS) is a cognitive test with 5 domains; raw scores can be converted to percentiles for age/education levels, so individuals can be compared. Higher scores mean more competence (0-36 points converted to percentiles so different ages can be compared). Total raw scores for the 5 domains were computed so that Mean and SD of differences between first and last assessments for all subjects, by study arms (nutriceutical = XL and placebo = PL) are reported here.

    Measured: Baseline and 12 months

  2. Differences in Clinical Dementia Rating Scale (CDR) Over 12 Months, by Study Group

    CDR is a rating scale for 8 aspects of behavior with 0-3 points allowed; higher scores indicate more pathology. Total minimum and maximum scores are 0 and 36 respectively.Clinician rates the patient's behavior and competence with input from family members who live with the patient. ANOVA of differences between baseline and end scores of the CDR scale are reported here, by the study arm/group.

    Measured: baseline before intervention to 12 months of intervention

  3. Differences in Clock Drawing Test (CLOX) Scores Over 12 Months, by Study Group

    Clock Drawing Test is a cognitive screening instrument in which subjects are to draw a clock and set a specified time. Various scoring methods can be employed using 4 to 15 points, with more points showing more competence. This study used the 8-point scoring method, so that 0-8 points could be assigned during each of the baseline and 4 assessment periods during the 12-month study. ANOVA of the differences between baseline and end scores, by study arm/group was completed.

    Measured: baseline to 12 months

  4. Differences in MiniMental State Exam (MMSE) Scores Over 12 Months, by Study Group

    MiniMental State Exam is a cognitive screening device with possible 30 points in several categories; higher points indicate greater competence. Clinician tests orientation, attention, language, \& visuo-spatial construction. Outcome measure is results of an ANOVA of differences between baseline and end/last scores, by study arm/group was completed.

    Measured: baseline to 12 months

  5. Differences in Neuropsychiatric Inventory (NPI) Scores Over 12 Months, by Study Group

    NPI is a behavior rating scale with 12 categories in which a maximum score of 36 points indicates more pathology than a minimum score of 0. Outcome measure reported here is results of an ANOVA of the differences between baseline and end scores, by study arm/group, to detect any statistically significant difference (nutriceutical vs placebo groups) was completed.

    Measured: baseline to 12 months

  6. Differences in Activities of Daily Living (ADL) Scores Over 12 Months, by Study Group

    ADL is a behavior rating scale with 6 domains of self-care (feeding, toileting, etc.) in which a maximum score of 18 indicates less competence than a minimum score of 6 (normal skills). Outcome measure is results of ANOVA of the differences between baseline and last/end scores, by study arm/group, to detect any statistically significant differences.

    Measured: baseline to 12 months

  7. Differences in Instrumental Activities of Daily Living (IADL) Scores Over 12 Months, by Study Group

    IADL is a behavior rating scale using 9 domains of household and community activities, with a total score of 27 points indicating less competence than a normal function score of 9 points. Outcome measure is results of an ANOVA of the differences between baseline and end/last score, by study arm/group, to detect statistically significant differences (nutriceutical vs placebo).

    Measured: baseline to 12 months

Secondary outcomes (1)
  1. Number of Subjects Who Converted to Early Alzheimer's (Dementia).

    Neurological diagnosis is based on test scores that reach -1.6 SD of mean for age/education, and on radiological tests of brain structure (CT, MRI, PET). Usual cutoff for test score percentile is <0.05 to diagnose dementia.

    Measured: 12 months
