NCT00842920

Brief Summary

Probands with MCI are at high risk to develop Alzheimer´s dementia (AD). Simvastatin may lower the production of Amyloid, a hallmark of AD in the brain. The primary hypothesis of the study is that 60 mg Simvastatin significantly reduces the Clinical Dementia Rating -Sum of boxes (CDR-SOB) in individuals with MCI as compared to MCI receiving placebo or 20 mg Simvastatin

Eligibility Criteria

Age55 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Self and informant report of gradually increasing memory impairment for at least six months.
  • Objective memory impairment
  • Intact basic activities of daily living
  • Preserved general cognitive function, not demented
  • Absence of a detectable cause of memory disorder
  • Age 55 to 90.
  • Females without childbearing potential
  • A total cholesterol ≥90 mg/dl
  • LDL-cholesterol ≥ 160 mg/dl and ≤ 3 risk factors or ≥ 190 mg/dl and ≤ 2 risk factors including age
  • Informed consent (according german medicinal products act, AMG §40 (1) 3b)
  • No participation in other clinical trials 2 months before and after participation in this study
  • Probands should only recruited for the clinical trial, when they are able to perform the informed consent; due to worsening of "memory function" in the course of the clinical trial, probands should not longer participate the clinical trial, when they is evidence, that participants were not longer able to give full informed consent.

You may not qualify if:

  • Hypersensitivity against Simvastatin, active liver disease or lasting increase of serum transaminases for unclear reason
  • Unstable medical, neurological or psychiatric disease
  • Lack of a spouse or a close relative
  • Use of a registered anti-dementia drug or a nootropic
  • Chronic use of anti-inflammatory drugs
  • History of stroke or myocardial infarction
  • LDL-cholesterol 130-160 mg/dl and \> 3 risk factors or 160-190 mg/dl and \> 2 risk factors including age.
  • LDL-cholesterol \>190 mg/dl
  • Comedication with Diltiazem, Verapamil, Amiodarone, Itraconazole, Ketoconazole, Erythromycin, Clarithromycin, Telithromycin, Ciclosporin, Gemfibrozil, Nefazodone, HIV-protease inhibitors, Benzodiazepines, Tricyclic antipsychotics or other anticholinergic drugs
  • Comedication of other statins in high doses; low doses equivalent to 20 mg Simvastatin are allowed if taken for max. 2 years before randomization
