A Dangerous Truth about Antidepressants

by Neuroskeptic in Neuroskeptic

An opinion piece by veteran psychiatrist and antidepressant drug researcher Sheldon Preskorn contains a remarkable historical note -“A dangerous idea!” That was the response after a presentation I gave to a small group of academic leaders with an interest in psychopharmacology [over 15 years ago].What evoked such a response? The acknowledgment that most currently available antidepressants specifically treat only one out of four patients with major depression based on the bulk of clinical tri........ Read more »

Do Antioxidant Supplements Negate the Beneficial Effects of Exercise?

by Scott Gavura in Skeptic North

I have skeptical confession to make. I was once a panacea-seeking antioxidant-taker. As background, I’m a marathon runner and occasional triathlete. Several years ago, I was training for an Ironman triathlon, and banking 20+ hours of intense exercise per week. That may sound absurd to many (it does to me, now that I have kids) [...]

The Gene That's "For" Nothing

by Neuroskeptic in Neuroskeptic

Scientists like to warn you not to talk about "the gene for" a particular disease or trait.I've done so in previous posts e.g. this one or this one.But such scalding is not always very effective. We like simple explanations, so we like to find simple connections between genes and phenotypes.Which is why a new paper is important. The authors, a large Turkish-American collaboration, found that mutations in a gene, WDR62, are associated with severe brain malformations in 9 patients. But what's inte........ Read more »

Marching with Allergies

by Paige Brown in From The Lab Bench

I have been living with allergies for 26 years now...

And yet after all of that time, I still have so much to learn about why my body reacts so violently to watermelons, cats, and dust-mites...

But what causes this apparent 'march' from one type of allergy to the next? Why do children with symptoms of eczema often grow into additional allergy symptoms, including hayfever and asthma? ... Read more »

Cranial Vault Modification or Alieeeeens?

by Kristina Killgrove in Powered By Osteons

As usual, a Daily Mail article caught my attention with its first line, "A mummified elongated skull from Peru could finally prove the existence of aliens."  The purpose of this kind of opener, of course, is to get people to read the tripe the Mail peddles.  According to the article, "three anthropologists agree: it is not a human being."  Well, if three unnamed Spanish and Russian anthropologists agree, then it must be an alien.



Alien?  Uh, no.  (Photo: The Nati........ Read more »

Sleep Disorders and Cognition in Older Men

by William Yates, M.D. in Brain Posts

Sleep Stage Architecture Figure with REM Sleep in RedSleep contributes to brain function through a variety of mechanisms.  Sleep functions change over the life cycle with older adults showing a greater amount of time in light sleep phases (stage 1 and stage 2 sleep).  Less time is typically spent among older adults in restorative or deep sleep (slow-wave sleep)  and rapid age movement sleep.Since dementia risk increases with age, it is natural to wonder how age-related sleep chang........

Avoiding the needle: Engineering blood vessels to secrete drugs

by Fliesler, Nancy in Vector, a Children's Hospital Boston blog

People who rely on protein-based drugs often have to endure IV hookups or frequent injections, sometimes several times a week. And protein drugs – like Factor VIII and Factor IX for patients with hemophilia, alpha interferon for hepatitis C, interferon beta for multiple sclerosis — are very expensive.

What if they could be made by people’s own bodies?

Combining tissue engineering with gene therapy, researchers at Children’s Hospital Boston showed that it’s pos........ Read more »

Was Evita Lobotomized?

by Neuroskeptic in Neuroskeptic

Eva Peron, or Evita, is perhaps the most famous woman in Latin American history. As the wife of Argentinian leader Juan Peron she was immensely popular. But she died at the age of just 33 from cervical cancer, after a two year struggle with the disease.A new paper makes the startling claim that Eva Peron may have received a prefrontal lobotomy in the months before her death. The lobotomy is best known as a treatment for mental disorders such as schizophrenia, but according to Nijensohn et al, Pe........ Read more »

Predictors of Self-Reported Knee Function in Nonoperatively Treated Individuals with ACL Injury

Basal Ganglia Including Substantia Nigra Key In Parkinson's DiseaseEarly identification of neurodegenerative disorders plays a key role in prompt intervention and surveillance.  A great deal of research is being conducted in the early identification of Alzheimer's disease.  Less attention has been placed on early identification of Parkinson's disease.
