The study compared levels of cholesterol and fats in cerebrospinal fluid (cerebrospinal fluid is found in the brain and spinal canal) in Alzheimers patients and subjects without Alzheimers. The study assessed the brain tissue at postmortem in 30 Alzheimers cases and 31 age-matched control patients.
The study found:
(a) Cholesterol levels in the cerebrospinal fluid of patients without alzheimer's was 55% higher than in patients with Alzheimer's.
(b) Fatty acid levels (fat molecules) in the cerebrospinal fluid of patients without alzheimer's was 522% higher than in patients with Alzheimer's.
(c) Phospholipid levels (phospholipids contain two molecules of fat and are a major component of cell membranes) in the cerebrospinal fluid of patients without alzheimer's was 1650% higher than in patients with Alzheimer's.
The results of the study show that Alzheimer’s patients have significantly reduced levels of cholesterol and fats in the cerebrospinal fluid.
