MedicalResearch.com Interview with: Manja Koch Dr. oec. troph. (Ph.D. equivalent) Research Associate Department of Nutrition Harvard T.H. Chan School of Public Health Majken K. Jensen, PhD Associate Professor of Nutrition Harvard T.H. Chan School of Public HealthMajken K. Jensen, PhD Associate Professor of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Alzheimer’s disease and other dementias are highly prevalent conditions. According to the Alzheimer’s Association, 50 million people are currently living with Alzheimer’s disease or other dementias worldwide. Given the lack of a cure or even disease-modifying therapies for most dementias, the identification of risk factors or factors that prevent or delay the onset of dementia remains of paramount concern. Alcohol is a globally consumed beverage and light-to-moderate alcohol consumption, defined as up to one drink per day for women and up to two drinks per day for men, tends to be associated with lower risk of cardiovascular disease, a major risk factor for dementia. However, the effects of light-to-moderate alcohol intake on the brain are less clear.  (more…)

MedicalResearch.com Interview with: Dr Miguel Chillon PhD Department of Biochemistry and Molecular Biology Universitat Autonoma Barcelona Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Klotho is a protein with an anti-aging and neuroprotective role. Recent studies show it prevents the development of cognitive problems associated with aging and Alzheimer's disease. Klotho works mainly by inhibiting the insulin / IGF-1 signaling pathway and decreasing the damage caused by oxidative stress in the brain. One of the latest results revealed that the concentration of Klotho in cerebrospinal fluid is significantly lower in Alzheimer's patients than in human controls of the same age; and it is lower in the elderly with respect to young adults. Our study used a gene therapy strategy to introduce the Klotho gene into the Central Nervous System of adult animals. With just a single injection of the Klotho gene, young adult animals were protected over time from the cognitive decline associated with aging in old animals. These exciting results pave the way to further advances in research and the development of a neuroprotective therapy based on Klotho. (more…)

Sven Haller, M.D. University of Geneva in Geneva, Switzerland. MedicalResearch.com Interview with: Sven Haller, M.D. University of Geneva in Geneva, Switzerland. Medical Research: What are the main findings of the study? Dr. Haller: The main finding is that some elderly individuals with intact cognitive function at baseline already have visible alterations of the brain perfusion measured in Arterial Spin Labeling (ASL)  MRI, which is similar to patients with mild cognitive impairment (MCI). This elderly individual may initially maintain intact cognitive functions due to the activation of their cognitive reserve, yet eventually the cognitive reserve is exhausted and those individuals develop subtle cognitive decline at follow-up 18 months later. Consequently, Arterial Spin Labeling MRI may predict the very earliest form of cognitive decline. (more…)

Dr. Erin Abner Ph.D. Assistant Professor of Epidemiology University of Kentucky College of Public Health Lexington, KentuckyMedicalResearch.com Interview with: Dr. Erin Abner Ph.D. Assistant Professor of Epidemiology University of Kentucky College of Public Health Lexington, Kentucky MedicalResearch.com: What are the main findings of the study? Dr. Abner:  The findings from this study are preliminary results from The Prevention of Alzheimer’s Disease with Vitamin E and Selenium Study. This early look at the data indicates that very simple measures of memory change, in this case asking older men with no cognitive impairment about changes in their memory over the past year, and whether they believe those changes are a problem, can be used to predict cognitive impairment years later. Men who said at study baseline that the changes in their memory represented problems to them were over twice as likely as men who did not complain to develop clinically detectable cognitive impairment during follow-up. This is exciting because the field of Alzheimer’s research is moving toward earlier intervention in the disease process. As of now, our best methods for identifying individuals without cognitive impairment who are likely to develop Alzheimer’s disease in the future are procedures that many people find intimidating, like lumbar puncture and PET scanning. Identifying older adults at high risk for future cognitive impairment with low-cost, non-invasive screening techniques would help researchers to target potential therapies to the people who stand to benefit the most.

Western Australia MedicalResearch.com: What are the main findings of your study? Answer: Our research indicates that consuming larger quantities of foods included in a western dietary pattern is associated with greater cognitive decline in visuospatial functioning after 36 months. Foods included in the western dietary pattern are red and processed meats, high fat dairy products, chips, refined grains, potatoes, sweets and condiments. Visuospatial functioning is an area which includes distance and depth perception, reproducing drawings and using components to construct objects or shapes. In contrast, adherence to the Mediterranean diet, a healthy eating pattern is associated with less decline in executive function. Foods included in the Mediterranean diet are vegetables, fruits and fish. Examples of executive function include planning and organising, problem solving and time management. (more…)
