Omega-3 fatty acid stops known trigger of lupus

by Dr. Jekyll in Lunatic Laboratories

A team of researchers has found that consuming an omega-3 fatty acid called DHA, or docosahexaenoic acid, can stop a known trigger of lupus and potentially other autoimmune disorders. DHA can be found in fatty, cold-water fish and is produced by the algae that fish eat and store in their bodies. It can be found in fish oil supplements as well, used by more than 30 million Americans.

Injury risk and ADHD

by Paul Whiteley in Questioning Answers

"The results indicate that there is an elevated injury risk among Swedish schoolchildren with ADHD [attention-deficit hyperactivity disorder] but not for children with ASD [autism spectrum disorder]."So went the findings reported by Carl Bonander and colleagues [1] providing yet more important data on how a diagnosis of ADHD might be something that confers quite a bit of additional risk for all-manner of different negative outcomes.I've hinted at this important topic before as per........

Locating social memories in the brain

by adam phillips in It Ain't Magic

Scientists have identified that social memories are stored in the vetral CA1 region of the brain (in mice). After meeting a mouse and forgetting it, the memories can be reactivated optogenetically, indicating that they exist, but cannot be retrieved after time passes... Read more »

The Terrorist Inside Robin Williams' Brain

by Neuroskeptic in Neuroskeptic_Discover

The journal Neurology published a unique and touching paper today: it's by artist Susan Schneider Williams, the widow of actor Robin Williams, who died by suicide in August 2014. It's titled The terrorist inside my husband's brain, the 'terrorist' being Lewy Body disease (LBD), the neurodegenerative disorder that, as Schneider Williams recounts, destroyed his life.





Here's how she describes the first signs of her husbands' illness:
The colors were changing and the air was crisp; it wa... Read more »

by Paul Whiteley in Questioning Answers

They've finally arrived. The results of the English Adult Psychiatric Morbidity Survey 2014 have been published by NHS Digital (yes, our Nation's healthcare services has a digital arm) and when it comes to autism (adult autism 18 years+), some rather peculiar statistics have been produced.OK, for those who want/need a quick heads-up on all-things Adult Psychiatric Morbidity Survey (APMS), I'll refer you to a previous post I wrote covering this prevalence survey with autism in mind........

On "socially successful elementary school-aged children with autism"

"School-based interventions should address malleable factors such as the number of peer connections and received friendships that predict the best social outcomes for children with ASD [autism spectrum disorder]."So said the study findings reported by Jill Locke and colleagues [1] looking at "the stable (unlikely to change) and malleable (changeable) characteristics of socially successful children with ASD."Mindful that the phrase 'socially successful children' is perhaps not one that I'm p........

Research team may have observed building blocks of memories in the brain

by Dr. Jekyll in Lunatic Laboratories

A team of researchers has observed what they believe are the building blocks of memories in a mouse brain. In their paper, the researchers describe how they caused certain neurons to become illuminated when they fired, allowing them to watch in real time as memories were made and then later as they were replayed while the mouse was sitting idle.

Lewy Body Versus Alzheimer's Dementias and Parkinson's

One clinical challenge is making an accurate diagnosis in patients with dementia.Alzheimer's disease is typically the predominant diagnosis in dementia. However a significant number of patients will present with dementia due to Lewy Body disease, Parkinson's dementia,  frontotemporal dementia or vascular dementia.A recent study helps clinicians to distinguish Lewy Body  from Alzheimer's dementia and Parkinson's disease.Douglas Scharre and collegues from Ohio State University conducted ........

When the writing is wrong: PRMT5 histone arginine methylation promotes invasivity and metastasis in a range of human cancers

by David Schecter in EpiBeat

Cancer metastasis occurs when cancer cells leave a primary tumor and invade other tissues. Generally, this leads to a poor prognosis for patients. Underlying epigenetic mechanisms of tumor progression are poorly understood but are of great interest for developing new approaches of treatment in the clinic. Cancer etiology is highly correlated with alterations in the histone code1-5 and protein methyltransferases are frequently dysregulated in cancer, implicating them as compelling novel targets f........

Postural tachycardia syndrome and gluten?

Please use your full stops wisely.I believe that this is the first time that I've talked about postural tachycardia syndrome (PoTS) on this blog as I bring to your attention some rather intriguing findings reported by Hugo Penny and colleagues [1] on how PoTS and gluten-related disorders might not be unstrange diagnostic bedfellows.PoTS by the way, describes symptoms where standing upright / sitting down induces dizziness, fainting and other symptoms.

The unintended consequences of almond milk on California

by Dr. Jekyll in Lunatic Laboratories

A new study using aerial imagery across the state of California has found that converting land to grow almonds between 2007 and 2014 has led to a 27% annual increase in irrigation demands—despite the state's historic drought. The expansion of almonds has also consumed 16,000 acres of wetlands and will likely put additional pressure on already stressed honeybee populations.
