Study type | Observational |
The study evaluates if the relationship between total serum cholesterol is dependent on the total serum homocysteine. Fasting blood samples will taken from participants and two batteries of cognitive scales will be used to asses any cognitive decline.

---|---|---|---|---|
Primary | correlations between serum total cholesterol and homocysteine levels and cognitive functions | Blood samples were collected after an overnight fast by using 10 mL plain tubes. Lipid profile was measured by using Cholesterol Kits and analyzed by COBAS Integra analyzer. Total cholesterol levels were measured using the sum of the LDL and HDL plus one-fifth of triglyceride levels. Samples of serum homocysteine (Hcy) are stored in specialized container at (-20?C) temperature. Total Hcy was measured by ELISA technique, Sinogen kits and Statfax-2100 micro-plate analyzer. Cognitive functions were measured by using the Arabic version of: the 30 points Mini Mental State Exam (MMSE) and the Memory Assessment Scale (MAS) which consists of 12 subtests and the degree of 100 points. The mean of total MAS plus MMSE degrees is used (e.g., (100+30)/2=65 Points which is the maximum score). High, normal and low cholesterol level is compared to the mean of cognitive score only in participants with normal homocysteine levels (below 14 umol/l), higher levels of Hcy is excluded. |
