Brief Summary:
Memory loss and difficulties with thinking associated with Alzheimer's disease (AD) may be due to a deficiency in the brain of a fatty acid named DHA. The aim of this trial is to see if dietary supplementation with a preparation, rich in DHA, will halt cognitive impairment in AD patients

Primary Outcome Measures :
  1. Cognition measured according to ADAS-cog, MMSE scales

Secondary Outcome Measures :
  1. Safety, tolerability, blood pressure
  2. Gene expression [ Time Frame: 2007-2018 ]
    mRNA expression and DNA methylation changes in blood leukocytes in relation to changes of plasma and cerebrospinal concentrations of omega-3 fatty acids

  3. Dose-response studies in relation to APOE4 status, to body weight and to gender [ Time Frame: 2007-2018 ]
    Analysis of changes of plasma and cerebrospinal fluid concentrations of omega-3 fatty acids in relation to APOE4 status, body weight and gender, as well as to changes in ADAS-cog and MMSE as measures of cognition.
