Is Knowledge Power? Direct-to-Consumer Genetic Testing
The completion of the sequencing of the human genome in 2003 was an outstanding scientific accomplishment. This achievement, together with advances in technology and the forces of capitalism and competition, has brought genetic testing directly to the consumer. However, this Pandora’s box is proving difficult to manage for many people.Direct-to-consumer (DTC) genetic tests are marketed to consumers primarily through the Internet. Consumers are motivated by education, recreation, and preventive health care, but the answers obtained from the tests do not necessarily provide meaningful information.
Bruxism and the Brain
Do you grind your teeth at night? Bruxism is the technical term for teeth grinding or teeth clenching that usually occurs in sleep. Bruxism may lead to jaw pain, shoulder pain, ear ache, and all sorts of other physical ailments.Have you ever wondered why some people grind their teeth at night? Some people clench their jaw and grind their teeth during the day, but nocturnal or night-time bruxism is what I’m referring to right now. I know many people who grind their teeth in their sleep and they have to wear night guards to protect the enamel on their teeth.
Are Physicians Spending Too Much Time Diagnosing Patients?
Dizziness is responsible for nearly 3 million emergency room visits every year in the United States. In most of the cases, the dizziness is caused by a benign inner ear problem, or is the result of short-lived discomfort or distress, including anxiety, depression, or certain phobias. However, approximately 4% of patients that present to the emergency room complaining of dizziness are experiencing a stroke or transient ischemic attack. Since more than half of patients with dizziness who are experiencing a stroke show no other symptoms, misdiagnosis is frequent and common. Now, a study published in the journal Stroke reports that a simple one-minute bedside eye exam could be more effective in diagnosing stroke than Magnetic Resonance Imaging (MRI).
Possible Medical Application of a Smart Drug
Cognitive enhancers, also known as nootropics, are a category of drugs with the ability to increase mental performance. Many rave about such “smart drugs” helping them to study, take tests, or increase work performance. Ginkgo biloba, piracetam, and vinpocetine are some popular cognitive enhancers, all with varying mechanisms of action in the human brain. For example, Ginko biloba increases blood circulation; the simple idea regarding its effect is that increased blood circulation results in a more energized brain. Still, the FDA has not yet confirmed how effective any of these “smart drugs” are; as a result, cognitive enhancers are presently deemed supplements.
