Generalized Anxiety Disorder: The Mind/Body Connection
GAD or generalized anxiety disorder is defined as a disorder characterized by irrational, uncontrollable worry about everyday issues and events. While someone without GAD may find themselves anxious in certain scenarios, persons with GAD may be almost paralyzed with anxiety in situations that should not generate that level of fear and worry. This anxiety may manifest itself physically through hot flashes, an accelerated heart beat, sweating, muscle aches, irritability and health issues.
Preteens Feel the Effects of Mom’s Pregnancy Bad Habits
It has been known for years that babies in utero (womb) suffer ill effects from their mothers' exposure to tobacco, drugs and alcohol. A new study funded by the National Institute on Drug Abuse and performed by Michael Rivkin of Children's Hospital Boston showed that children exposed to these toxins may suffer effects well into early adolescence.Using MRI technology, the study looked into the long term effects of prenatal exposure to drugs, alcohol, tobacco or a combination of the three on the brain structure of preteens. The study found that these kids have thinner cortical grey matter than subjects who did not suffer exposure to toxins in utero. This study also showed a reduction in brain volume directly tied to this exposure.
The Timing of Plaque Formation is a Critical Factor in Alzheimer’s Dementia
Researchers at the MassGeneral Institute for Neurodegenerative Disease (MGH-MIND) and Washington University School of Medicine have recently shifted their focus of Alzheimer's disease (AD) research from understanding the role that plaques and other neurological changes play in the progression of AD. Now they are looking at the time period and order in which plaques and neurological changes like dementia and senility occur in the progression of AD.
New Anti-Cancer Drug for Aggressive Brain Tumors
Researchers are constantly trying to find new drugs or forms of therapy that can be used to treat cancer. Quite often when a possible treatment is discovered, being allowed to test a drug or other experimental cancer treatment at a clinical level is difficult. For example, after an anti-carcinogenic drug has been thoroughly tested at the experimental level it is necessary to test it in humans to analyze factors such as the drug’s anti-tumor activity, its ability to interact with a specific target, and to discover which patients are more likely to benefit from the drug. These types of early clinical trials are the key in the successful implementation of effective anti-tumor drugs and therapies.
