Medical Notes this week…
Epilepsy, essential tremor and Parkinson’s disease afflict about 100 million people around the world. For some of them, the only relief comes from deep brain stimulation, where an electrode is implanted deep in the brain for later activation. But a new study in the journal ACS Nano shows that the injection of nanoparticles deep into the brain can produce the same effect. The particles are activated when hit by x-rays from a small machine similar to what’s in your dentist’s office. Scientists say the same concept might also be used for chronic pain and depression.
Diagnoses for the four most common cancers take a big jump when people hit age 65… and a new study finds that medicare is the reason. The study in the journal Cancer shows that rates for lung, breast, colon and prostate cancer double in 65 year olds, compared to people age 61 to 64. Researchers say people are waiting until they’re covered by medicare before they get help… often because they have no insurance at all until then.
And finally…narcissistic people spend a lot of time congratulating themselves about how wonderful they are. But a new study shows that they pump themselves up only because deep down inside, they don’t believe they’re any good. The study in the journal Personality and Individual Differences shows that insecurity drives narcissist’s claims of being smarter and having better taste than other people… which drives even more people away in a vicious cycle.
