This retrospective analysis of de-identified data from 700 charts of consecutive patients from this patient population is to investigate the prevalence of hyperhomocysteinemia and associated metabolic abnormalities in this naturalistic grouping of patients with various stages of cognitive loss and diagnosed with various types of dementia.

Mild Cognitive Impairment

Study Type: Observational
Study Design: Time Perspective: Retrospective
Official Title: Hyperhomocysteinemia in a Mild Cognitive Impairment and Dementia Population: the Effect of Treatment With Cerefolin NAC® in a Naturalistic Community-based Dementia Practice

Further study details as provided by Pamlab, Inc.:

Primary Outcome Measures:
  • Change from Baseline in Levels of Homocysteine Over Time [ Time Frame: Week 6, Week 12, and Quaterly Thereafter @ 6 Month Intervals ]
    To analyze homocysteine levels, cognitive test scores and depression level to determine the prevalence of hyperhomocysteinemia and associated metabolic abnormalities and compare results of patients on Cerefolin NAC® alone to patients on Cerefolin NAC® in combination with standard of care memory and/or depression medications.

Secondary Outcome Measures:
  • To evaluate the safety and tolerability of Cerefolin NAC® based on adverse events, discontinuation due to intolerability and compliance. [ Time Frame: Baseline, Week 6, Week 12, and Quarterly Thereafter @ 6 Month Intervals ]
  • Examine the demographics, medical co-morbidities present and affective and cognitive characteristics of the group of patients demonstrating hyperhomocysteinemia compared with the group without hyperhomocysteinemia in a dementia population. [ Time Frame: Baseline, Week 6, Week 12, and Quarterly Thereafter @ 6 Month Intervals ]

Estimated Enrollment: 700
Study Start Date: January 2013
Estimated Study Completion Date: April 2014
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Patients Treated with CerefolinNAC®
Patients Not Treated with CerefolinNAC®

Detailed Description:

A single-center, retrospective review of the medical charts of 700 de-identified elderly patients who underwent evaluation and treatment for cognitive loss including analysis of:

Laboratory values of interest: homocysteine, methylmalonic acid, CRP, BNP, CO2, TSH, Fe/TIBC, RPR/TPPA/FTA-ABS, and if available, folic acid and B12 levels ordered by primary care providers.

Neuropsychological tests of executive function, memory and affect:

  • Wechsler Memory Scale-Revised (WMS-R) or Fourth Edition (WMS-IV)

    • Logical Memory -Delayed Recall, Scaled Score
    • Visual Reproduction-Delayed Recall, Scaled Score
  • Shopping List Test, Delayed Recall
  • Trailmaking A and B Tests
  • Verbal Absurdities subtest of the Stanford Binet, Form L-M
  • Proverbs Test
  • Memory Orientation Screening Test
  • Folstein Mini-Mental State Exam
  • Geriatric Depression Scale, 15 items

Sub-group analysis of MRI volumetrics and PET scans when available. Sequentially pulled from June 1, 2009 to September 2011
