Leisure activities lower blood pressure in Alzheimer's caregivers

Greater engagement in pleasant leisure activities was associated with lowered caregivers' blood pressure over time," according to the report by Brent T. Mausbach, PhD, of University of California San Diego and colleagues. "Participation in pleasant leisure activities may have cardiovascular benefits for Alzheimer's caregivers." The study included 126 caregivers enrolled in the UCSD Alzheimer's Caregiver Study, a follow-up study evaluating associations between stress, coping, and cardiovascular risk in Alzheimer's caregivers. The caregivers were 89 women and 37 men, average age 74 years, providing in-home care for a spouse with Alzheimer's disease. As part of annual interviews over five years, the caregivers provided information on how often they engaged in various pleasant leisure activities. These ratings were analyzed for association with blood pressure over time, with adjustment for demographic and health factors. The caregivers reported hi...

Anti-epilepsy drug restores normal brain activity in mild Alzheimer's disease

In a recent feasibility study, clinician-scientists at Beth Israel Deaconess Medical Center (BIDMC) tested an anti-epileptic drug for its potential impact on the brain activity of patients with mild Alzheimer's disease. The team, led by Daniel Z. Press, MD, of the Berenson-Allen Center for Non-invasive Brain Stimulation at BIDMC, documented changes in patients' EEGs that suggest the drug could have a beneficial effect. The research was published in the  Journal of Alzheimer's Disease . "In the field of Alzheimer's disease research, there has been a major search for drugs to slow its progression," said Press, an Instructor of Neurology in the Cognitive Neurology Unit at BIDMC and an Associate Professor of Neurology at Harvard Medical School. "If this abnormal electrical activity is leading to more damage, then suppressing it could potentially slow the progression of the disease." In this double-blind within-subject study, a small group of patie...

These vessels defend the mind and central nervous system from dangerous chemical compounds circulating within the blood. But this safety system -- referred to as the blood-brain barrier -- additionally prevents supply of medication that might assist deal with sufferers with mind cancers and mind illnesses reminiscent of Alzheimer's illness.

Large-scale production of living brain cells enables entirely new research

After performing a biopsy on the patient, the skin cells are transformed into brain cells that effectively imitate the disease and the age of the patient . The fact that the cells can now be produced in large quantities enables researchers to carry out a series of experiments that were previously not possible. A few years ago, Malin Parmar's research team was one of the first in the world to convert human skin cells directly into brain cells without passing the stem cell state. The discovery shocked the researchers and was perceived as almost impossible. The team is now approaching a point where the discovery is about to bear fruit on a wide scale. By following a new method that involves slightly changing the genetic code that triggers cell conversion, the researchers were able to multiply the production of disease-specific brain cells. "Primarily, we inhibited a protein, REST, involved in establishing identity in cells that are not nerve cells. After limiting this prot...

Alzheimer's gene associated with failure to adapt to cognitive challenge in healthy adults

Karen Rodrigue and colleagues assessed the performance of 31 adults (ages 20-86) with APOE4 on a distance judgment task at different levels of difficulty while measuring their brain activity. Although these at-risk participants showed similar adjustment in brain activity to the difficulty of the task as non-APOE4 carrying adults of the same age, sex, and education level, this ability declined with increasing age in the individuals with APOE4. These changes occurred in the precuneus, a part of the brain implicated in the early stages of AD, and reduced modulation of this area was associated with poorer performance on the task. These findings may help to inform the identification of individuals at increased risk of developing the disease . for more information visit our product website;      Buy Caverta 100 mg Online

Brains evolved to need exercise

In a new article published in the journal  Trends in Neurosciences , University of Arizona researchers suggest that the link between exercise and the brain is a product of our evolutionary history and our past as hunter-gatherers. UA anthropologist David Raichlen and UA psychologist Gene Alexander, who together run a research program on exercise and the brain, propose an "adaptive capacity model" for understanding, from an evolutionary neuroscience perspective, how physical activity impacts brain structure and function. Their argument: As humans transitioned from a relatively sedentary apelike existence to a more physically demanding hunter-gatherer lifestyle, starting around 2 million years ago, we began to engage in complex foraging tasks that were simultaneously physically and mentally demanding, and that may explain how physical activity and the brain came to be so connected. "We think our physiology evolved to respond to those increases in physical activity ...

Why social isolation can bring a greater risk of illness

Adpated from Colwell (2007) Nature Neuroscience Social isolation has been linked to a variety of well being issues, in addition to a shorter lifespan in people and different animals. In actual fact, throughout a U.S. Senate listening to on growing older points this spring, a consultant for the Gerontological Society of America urged lawmakers to assist packages that assist older adults keep linked to their communities, stating that social isolation is a "silent killer that locations individuals at greater danger for a wide range of poor well being outcomes." Now, researchers on the Perelman Faculty of Medication on the College of Pennsylvania have discovered a attainable rationalization for this affiliation. The group noticed that within the fruit fly Drosophila melanogaster, social isolation results in sleep loss, which i...
