The influence of medicines taken by patients on their cognitive abilities and the memory

In 2013 in a scientific journal Alzheimer’s and Dementia, group of researchers from the St. Louis in the USA published results of studies performed on group of 4414 patients in age 50 and above – men and women. For the examination were enrolled volunteers with normal cognitive abilities and the memory checked with battery psychometric tests. Patients filled in the questionnaire form describing taken medicines. After the end of one year a compliance of taking determined medicines with the decline of cognitive abilities was examined. Out of the list of over 100 preparations (of medicines and supplements of the diet) 9 preparations had established the link with the condition of cognitive fitness. Six of them had positive influence on retaining the decline of intellectual fitness and three influenced it negatively. Positively acting were naproxen, calcium plus vitamin D, sulphate of iron, potassium chloride, flaxseed, and sertraline and negatively influenced cognition bupropion, oxybutynin and furosemide. Amongst medicines positively acting it is worthwhile to put attention to calcium in combination with the vitamin D and flaxseed or linseed oil. Suplementation of the diet with vitamin D and omega-3 fatty acids contained in the flaxseed as well as in fish oils are considered as a good way of prevention of the Alzheimer’s disease and as the factor slowing down the course of Alzheimer?s disease.

Influence of the change of the traditional diet in Japan and a few developing countries on the incidence of the Alzheimer’s disease in these countries.

Amongst the researchers dealing with the Alzheimer’s disease more and more a view is becoming widespread, that diet and dietary history of individuals and averaged for the entire human population is significant for the susceptibility to develop Alzheimer?s disease (AD) of the entire population. This year a publication was published in Journal of Alzheimer’s Disease, authored by William B. Grant, analysing historical tendencies of the change of the diet in Japan and eight developing countries with reference to the prevalence of the Alzheimer’s disease in these countries. For Japan the factors strongly correlating with the increase of AD prevalence were: increased alcohol, animal products ? meat consumption, and the number of people smoking tobacco (measured by the amount of cases of the lung cancer). Negatively and strongly correlating was decrease in rice consumption. Change of dietary habits 10-15 years earlier influenced the prevalence of the Alzheimer’s disease much later. The author observed the similar period of delayed effects of the change of the diet for other eight developing countries. For these countries most strongly correlated with the increase in the number of cases: the increase of consumption of animal fats and increase in the caloric value of meals. The most important conclusion from this publication is that a significant risk factor for falling ill with the Alzheimer’s disease is what we ate in the past. In my opinion Polish diet containing quite a lot of complex carbohydrates (in the form of potatoes, groats, rice, bread) in spite of eating quite a lot of animal fats along with the influence of other factors is causing that an incidence of AD in Poland is on an average level by comparison with other countries.
