Even among non-dependent cocaine users, cues associated with consumption of the drug lead to dopamine release in an area of the brain thought to promote compulsive use, according to researchers at McGill University.
A study has found that abnormal proteins found in Alzheimer's, Parkinson's and Huntington's diseases share a similar ability to cause damage when they invade brain cells. The finding suggests that an effective treatment for one neurodegenerative disease might work for other neurodegenerative diseases as well.
In a new study, researchers at Lawson Health Research Institute and Western University are demonstrating that gait, or motion testing, while simultaneously performing a cognitively demanding task can be an effective predictor of progression to dementia and eventually help with earlier diagnosis.
A study from the Center for BrainHealth at The University of Texas at Dallas shows that a specific instructor-led brain training protocol can stimulate structural changes in the brain and neural connections even years after a traumatic brain injury (TBI). The findings, published in Brain and Behavior, further suggest that changes in cortical thickness and neural network connectivity may prove an effective way to quantitatively measure treatment efficacy, an ability that has not previously existed.
A study carried out in mice may help explain why dieting can be an inefficient way to lose weight: key brain cells act as a trigger to prevent us burning calories when food is scarce.
Vitamin D supplementation combined with good sleeping habits may help manage pain-related diseases. This paper published in the Journal of Endocrinology, reviews published research on the relationship between vitamin D levels, sleep and pain management, and reports that levels of vitamin D combined with good quality sleep could help manage conditions including arthritis, menstrual cramps and chronic back pain.
A new Iowa State University study may have identified the link that explains years of conflicting research over a mitochondrial gene and the risk for Alzheimer's disease. Researchers found a dramatic difference in the gene's impact on memory, general cognitive function and risk based on a family history of Alzheimer's disease and the length of a specific section of the gene.
A new DNA vaccine when delivered to the skin prompts an immune response that produces antibodies to protect against toxic proteins associated with Alzheimer's disease -- without triggering severe brain swelling that earlier antibody treatments caused in some patients.
A new study suggests that men and women are affected differently by sleep disorders. Results show that women are more likely than men to have more severe symptoms of depression, trouble sleeping at night, and excessive daytime sleepiness. Women also have a higher degree of difficulty concentrating and remembering things due to sleepiness or tiredness. In contrast, male snoring was more likely than female snoring to force bed partners to sleep in different rooms.
For the first time, researchers of the University of Zurich and Swiss Federal Institute of Technology in Zurich have demonstrated the causal context of why deep sleep is important to the learning efficiency of the human brain. They have developed a new, noninvasive method for modulating deep sleep in humans in a targeted region of the brain.
