A Nicotine Patch a Day Keeps the Cognitive Impairment Away
Normally, a nicotine patch on someone’s arm is evidence that they are trying to quit smoking. But, soon, nicotine patches may be appearing on arms of the cognitively impaired.A study published in the journal Neurology reported that transdermal nicotine administration improved the symptoms of cognitive impairment in nonsmoking adults. In a randomized, double-blind, placebo-controlled study, 74 nonsmoking adults with mild cognitive impairment received either 15 mg of nicotine or placebo daily for 6 months. (Most smoking cessation patches deliver between 7 and 21 mg of nicotine per day.) At the end of the study period, the subjects showed significant improvement in most measures of cognitive function, including attention, memory, and psychomotor speed.
Media Violence Leads to Real Violence
A few short decades ago, the most violent scenes we were exposed to in the media involved Wile E. Coyote and an anvil. The nightly news did not display graphic evidence of riots or murders or even war. Movies did not market themselves based on the amount of gunfire packed into two hours. Video games were little more than a bouncing ball controlled by a joystick. But, society has changed and, now, violence is everywhere. Children and adolescents are exposed to violent images everyday and the line between reality and fiction is blurred. Now, the consequences of such exposure are becoming evident and recent studies show neurological adaptations and desensitization that lead to aggression and violence in real life.
Childhood Aggression Predicts Health Care Use Later in Life
Young children can be physically aggressive, owing to a combination of instinct, temperament, cultural and social influences, and (sometimes) not getting what they want. But, by the time most kids reach preschool age, they have learned to control their aggression with coping skills and relational techniques. However, children who do not learn to regulate aggressive behavior are at risk for physical and mental health issues, as well as serious patterns of aggression and violence, as adults. A new study, published in the Canadian Medical Association Journal, shows that the more aggressive a young child is the more likely he or she is to use health care services as an adult.
Risks of Personalized Medicine
Anyone who has taken high school biology has probably heard one of the corniest biology jokes around: How do you tell a girl chromosome from a boy chromosome? Pull down its genes. While this has been a useful (if not really funny) mnemonic for teaching students about life science, now individuals are beginning to play genetic versions of I'll-show-you-mine-if-you-show-me-yours by actually examining their genes. Not much more than a decade has passed since the completion of the Human Genome Project, but, already, direct-to-consumer (DTC) genome mapping and genetic testing are available with little more than a cotton swab and an envelope between you and your DNA.
