Autistic traits in adult-onset psychiatric disorders?

by Paul Whiteley in Questioning Answers

"To conclude, the presentation of ALTs [autistic-like traits/symptoms] at the sub-threshold or threshold level may be closely associated with BPD [bipolar disorder] and SZ [schizophrenia]."That was the conclusion reached in the paper by Junko Matsuo and colleagues [1] (open-access here) based on their analysis of nearly 300 adults aged between 25-59 years including those diagnosed with "MDD [major depressive disorder], n=125; bipolar disorder, n=56; schizophrenia,&n........

Artificial blood vessel lets researchers assess clot removal devices

by Dr. Jekyll in Lunatic Laboratories

For the first time, researchers have created an in vitro, live-cell artificial vessel that can be used to study both the application and effects of devices used to extract life-threatening blood clots in the brain. The artificial vessel could have significant implications for future development of endovascular technologies, including reducing the need for animal models to test new devices or approaches....

Mapping the language system: Part 2

by Dan Mirman in Minding the Brain

This is the second of a multi-part post about a pair of papers that just came out (Mirman et al., 2015, in press). Part 1 was about the behavioral data: we started with 17 behavioral measures from 99 participants with aphasia following left hemisphere stroke. Using factor analysis, we reduced those 17 measures to 4 underlying factors: Semantic Recognition, Speech Production, Speech Recognition, and Semantic Errors. For each of these factors, we then used voxel-based lesion-symptom mapping (........ Read more »

Rhabdomyomas: an additional BHD hamartoma phenotype?

by Danielle Stevenson in BHD Research Blog

Hamartomas are benign, focal malformations formed by an excess of normal tissue growing in a disorganised fashion. Several hamartoma syndromes have been linked to aberrant mTOR signalling including BHD and Tuberous Sclerosis Complex (TSC). In addition to the predisposition of BHD patients to develop hair follicle hamartomas or fibrofolliculomas (Birt et al., 1977), Fuyura et al., (2012) propose that the pulmonary cysts in BHD patients are hamartoma-like cystic alveolar formations. The benign nat........ Read more »

Higher cancer mortality rates associated with mental illness

by Paul Whiteley in Questioning Answers

The findings reported by Steve Kisely and colleagues [1] were of some interest recently and their assertion that despite cancer incidence being "the same as the general population for most psychiatric disorders" or even slightly reduced when a diagnosis of schizophrenia was for example received, mortality due to cancer was "increased in psychiatric patients."Such findings were based on their examination of: "Mental health records [that] were linked with cancer registrations and death r........

Could maple syrup help cut use of antibiotics?

by Dr. Jekyll in Lunatic Laboratories

Another reason to have those waffles… well maybe. Researchers have found that a concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics. In an ever increasing antibiotic resistant world, this news is almost as sweet as the syrup (okay no more bad puns). The findings suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.... Read more »

What is Neurofeedback Training for ADHD?

by William Yates, M.D. in Brain Posts

There are a variety of behavioral strategies for treating the attention and activity components of attention deficit hyperactivity disorder (ADHD).One of these strategies is known as neurofeedback. A recent study in the journal Pediatrics found evidence for effectiveness of in-school neurofeedback for ADHD in a randomized controlled trial.In this trial, 104 children between the ages of 7 and 11 years of age were randomized to one of three research arms: in-school neurofeedback, cognitive th........

Mapping the language system: Part 1

by Dan Mirman in Minding the Brain

My colleagues and I have a pair of papers coming out in Nature Communications and Neuropsychologia that I'm particularly excited about. The data came from Myrna Schwartz's long-running anatomical case series project in which behavioral and structural neuroimaging data were collected from a large sample of individuals with aphasia following left hemisphere stroke. We pulled together data from 17 measures of language-related performance for 99 participants, each of those participants was also........

Imagine a world without vaccines. The recent measles outbreak in Disneyland is providing us with a very small taste of what such a world would be like. Today on THE 'SCOPE, we go back in time to the age of smallpox and review the fascinating discoveries that led Edward Jenner to invent vaccination, a process that has saved countless lives....

Paternal sperm epigenetic differences and offspring autism risk

by Paul Whiteley in Questioning Answers

"These data suggest that epigenetic differences in paternal sperm may contribute to autism risk in offspring."So said the preliminary study results published by Jason Feinberg and colleagues [1]  (open-access) looking at "paternal semen biosamples obtained from an autism spectrum disorder (ASD) enriched-risk pregnancy cohort, the Early Autism Risk Longitudinal Investigation (EARLI) cohort." Researchers analysed 44 semen samples to ascertain whether DNA methylation differences - one typ........ Read more »

Brain development suffers from lack of fish oil fatty acids

by Dr. Jekyll in Lunatic Laboratories

While being inundated with advertisements directed at moms to be, skeptical parents should question the supposed health benefits of anything being sold. However, while recent reports question whether fish oil supplements support heart health, scientists have found that the fatty acids they contain are vitally important to the developing brain. Meaning there might actually be truth in advertising -- this time at least.... Read more »

Maternal diabetes and offspring autism risk... again

by Paul Whiteley in Questioning Answers

"In this large, multiethnic clinical cohort of singleton children born at 28 to 44 weeks’ gestation, exposure to maternal GDM [gestational diabetes mellitus] diagnosed by 26 weeks’ gestation was associated with risk of ASD [autism spectrum disorder] in offspring."That was the conclusion reached by Anny Xiang and colleagues [1] (open-access) following their analysis of some 3300 children diagnosed with ASD as part of a wider cohort of over 300,000 children "born in 19........

Watch out Atkins: Over eating fatty foods can alter your muscle metabolism

by Dr. Jekyll in Lunatic Laboratories

More bad news on the obesity front and strangely enough, on the popular diet front too — at least for diets like atkins. New research shows that even short term high-fat diets can change your metabolism. So while you might think that you can get away with eating fatty foods for a few days without it making any significant changes to your body, think again.... Read more »

Global Temperature Rise and Human Health - How is the World Coping?

by Sarah Stephen in An ecological oratorio

Global temperatures have been on the rise since the Industrial Age due to human activity such as the emissions of greenhouse gases from fossil fuel burning, large-scale deforestation, expansion of urban areas where vegetation cover is replaced by artificial heat retaining materials such as asphalt and concrete, some agricultural practices, and waste management activities. Data from the National Climatic Data Centre that  maintains the world's largest climate data archive indicate that the a........ Read more »

Immune signature in ME/CFS detected in cerebrospinal fluid

by Paul Whiteley in Questioning Answers

The research tag-team that is Mady Hornig and Ian Lipkin are fairly frequently mentioned on this blog. If it's not to do with their studies in autism research (see here for a recent mention) it is with their ground-breaking work looking at chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) in mind (see here for example).Indeed their latest paper [1] extends some recent findings (see here) on immune involvement in relation to CFS/ME [2] with a focus on examinations in cerebrospinal flu........
