Too much attention can be a deficit

by Dr. Jekyll in Lunatic Laboratories

Sometimes being too focused on a task is not a good thing. During tasks that require our attention, we might become so engrossed in what we are doing that we fail to notice there is a better way to get the job done. For example, let’s say you are coming out of a New York City subway one late afternoon and you want to find out which way is west. You might begin to scan street signs and then suddenly realize that you could just look for the setting sun.... Read more »

Screening for autism in preterm infants

by Paul Whiteley in Questioning Answers

"A positive screen on the M-CHAT [Modified Checklist for Autism in Toddlers] occurs more commonly in very preterm infants than those born at term."So said the study by Peter Gray and colleagues [1] as the topic of preterm status - that is, babies born alive before 37 weeks of pregnancy - potentially being linked to a greater risk of autism or at least, increased risk of screening positive for autism, crops up yet again on this blog (see here).Gray et al examined a cohort of children bo........

Researchers find how body’s good fat talks to the brain

by Dr. Jekyll in Lunatic Laboratories

There are two types of fat we humans have — white and brown — unfortunately only one of them is “good fat” and it is unfortunately not the one we tend to produce. Well new research shows that brown fat tissue, the body’s “good fat,” communicates with the brain through sensory nerves, possibly sharing information that is important for fighting human obesity, such as how much fat we have and how much fat we’ve lost....

Research on medical abortion/miscarriage may change international routines

by Dr. Jekyll in Lunatic Laboratories

Two scientific studies are expected to form the basis of new international recommendations for the treatment of medical abortions and miscarriages. One of the studies shows that it is possible to replace the clinical follow-up examinations recommended today with medical abortions that include a home pregnancy test. The other study shows that midwives can safely and effectively treat failed abortions and miscarriages in rural districts of Uganda.... Read more »

Music played by professionals activates genes for learning and memory

by Dr. Jekyll in Lunatic Laboratories

Music performance is known to induce structural and functional changes to the human brain and enhance cognition. However, the molecular mechanisms underlying music performance have been so far unexplored. A Finnish research group has now investigated the effect of music performance (in a 2 hr concert) on the gene expression profiles of professional musicians from Tapiola Sinfonietta (a professional orchestra) and Sibelius-Academy (a music university)....

Inflammation impairs social cognitive processing

by Paul Whiteley in Questioning Answers

A quote to begin: "acute inflammation can lead to decreases in the ability to accurately and reliably comprehend emotional information from others."It comes from the article published by Mona Moieni and colleagues [1] who examined a concept familiar to many people with a connection to autism either personally or professionally: Theory of Mind (ToM). Rather interestingly, Moieni et al "examined whether exposure to an experimental inflammatory challenge led to changes in ToM." Inflammato........ Read more »

High-fat diet causes brain inflammation and alters behavior

by Dr. Jekyll in Lunatic Laboratories

We hear in the media all the time, obesity is effecting our health. In most cases when we talk obesity we are talking about heart disease, sedentary activity, or chronic overeating. But what if a high-fat diet — regardless of obesity — has more than just an affect on your waistline? What if the consumption of fatty foods can change your behavior and your brain?... Read more »

The Smell of Stress and Fear

by Aurametrix team in Olfactics and Diagnostics

Can we recognize if people around us are stressed, anxious or fearful without observing their facial expressions, body language and actions or hearing their voice and messages? Can we understand if we are stressed ourselves without assessing our heart rate, blood pressure, noticing dry throat, sweating, drops or surges in energy? Yes, we can - by using our nose - as humans, too, recognize and transmit their emotions through chemical senses.When we are stressed or panic we become more sensit........ Read more »

Immunotherapy, a promising new treatment of Alzheimer’s disease

by Dr. Jekyll in Lunatic Laboratories

Alzheimer’s disease, it slowly takes things away from the person without giving anything back. Right now there is no cure and at best we can slow the progression in some cases. Time is always a factor and no two cases are the same. However, new treatments are in the works and a new study has revealed that a single dose of an immunotherapy reverses memory problems in an animal model of Alzheimer’s disease.... Read more »

MoBa does bowel issues in autism

by Paul Whiteley in Questioning Answers

'MoBa' in the title of this post, refers to the Norwegian Mother and Child Cohort Study and a handy resource which has already impacted on autism research (see here for example).Now MoBa has turned its epidemiological clout to an issue which less and less is encountering scientific resistance: are gastrointestinal (GI) symptoms over-represented when it comes to a diagnosis of autism? Further, when do such bowel issues start to present?The answer, shown in the paper by Michaeline B........ Read more »

Cracking the blood-brain barrier with magnetic nanoparticles

by Dr. Jekyll in Lunatic Laboratories

The blood-brain barrier, the thorn in the side of medicine. It makes using drugs directed for the brain ineffective at best and unusable at worst. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. This barrier means that currently 98% of therapeutic molecules are also unable to cross to the brain. However, researchers now say magnetic nanoparticles can open the blood-brain barrier and deliver molecules ........ Read more »

Autism and depression: interlinked?

by Paul Whiteley in Questioning Answers

"A possible implication is that interventions aimed at either autism symptoms or symptoms of depression may improve the other."That was the intriguing statement made by Per Normann Andersen and colleagues [1] who "investigated the course of and association among changes in autism symptoms, depression symptoms and executive functions (EF) in children with high-functioning autism (HFA)." Aside from frowning a little at the mention of the concept of 'high-functioning' I assume to denote those ........ Read more »
