Yoga’s Ability To Improve Mood And Lessen Anxiety Is Linked to...

Yoga has a greater positive effect on a person's mood and anxiety level than walking and other forms of exercise, which may be due to higher levels of the brain chemical GABA according to an article in The Journal of Alternative and Complementary Medicine, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online.

Lack Of Sleep Makes Your Brain Hungry

New research from Uppsala University shows that a specific brain region that contributes to a person's appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people's risk of becoming overweight in the long run.

Alzheimer’s Damage Occurs Early

The first changes in the brain of a person with Alzheimer's disease can be observed as much as ten years in advance -- ten years before the person in question has become so ill that he or she can be diagnosed with the disease. This is what a new study from Lund University in Sweden has found.

Feel-Good Glass For Windows

Daylight acts on our body clock and stimulates the brain. Fraunhofer researchers have made use of this knowledge and worked with industry partners to develop a coating for panes of glass that lets through more light. Above all, it promotes the passage through the glass of those wavelengths of light that govern our hormonal balance.

Moderate Exercise Dramatically Improves Brain Blood Flow In Elderly Women

Research conducted at Texas Health Presbyterian Hospital's Institute for Exercise and Environmental Medicine in Dallas suggests that it's never too late for women to reap the benefits of moderate aerobic exercise. In a 3-month study of 16 women age 60 and older, brisk walking for 30-50 minutes three or four times per week improved blood flow through to the brain as much as 15%.

New Evidence That Caffeine Is A Healthful Antioxidant In Coffee

Scientists are reporting an in-depth analysis of how the caffeine in coffee, tea, and other foods seems to protect against conditions such as Alzheimer's disease and heart disease on the most fundamental levels.

How The Brain Senses Nutrient Balance

There is no doubt that eating a balanced diet is essential for maintaining a healthy body weight as well as appropriate arousal and energy balance, but the details about how the nutrients we consume are detected and processed in the brain remain elusive. Now, a research study discovers...

Physical Activity Linked To Lower Rates Of Cognitive Impairment

Engaging in regular physical activity is associated with less decline in cognitive function in older adults, according to two studies published Online First by Archives of Internal Medicine, one of the JAMA/Archives journals. The articles are being released on July 19 to coincide with the International Conference on Alzheimer's Disease in Paris and will be included in the July 25 print edition.

Fish Oil May Have Positive Effects On Mood, Alcohol Craving, New...

Omega 3 fatty acids may be beneficial for more than just the heart. Researchers at the Indiana University School of Medicine have found at a molecular level a potential therapeutic benefit from these dietary supplements for treating alcohol abuse and psychiatric disorders.

Compound Derived From Curry Spice Is Neuroprotective Against Stroke And Traumatic...

A synthetic derivative of the curry spice turmeric, made by scientists at the Salk Institute for Biological Studies, dramatically improves the behavioral and molecular deficits seen in animal models of ischemic stroke and traumatic brain injury (TBI). Two new studies suggest that the novel compound may have clinical promise for these conditions, which currently lack good therapies.

Brain Scans Show Specific Neuronal Response To Junk Food When Sleep-Restricted

The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain that were less active when participants had adequate sleep, according to a new study using brain scans to better understand the link between sleep restriction and obesity.

Could Alzheimer’s Disease Be Diagnosed With A Simple Blood Test?

A pilot study suggests infrared analysis of white blood cells is a promising strategy for diagnosis of Alzheimer's disease. Spanish researchers, led by Pedro Carmona from the Instituto de Estructura de la Materia in Madrid, have uncovered a new promising way to diagnose Alzheimer's disease more accurately.
