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........

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.

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 ........

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........

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  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.

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.

What do you see in the picture? An elephant, right?
Some will say that they see an African elephant, or perhaps an elephant in the savannah protecting from the sun in the shade of a tree. But who sees an elephant and a majestic flowering baobab surrounded by savannah shrubs in a dry grass meadow?
If your answer is the latter, congratulations, you are a quite unique case. If in the picture you just see “an elephant” then you are just like most of the people around you.

"Elevated peripheral pro-NT [neurotensin] levels reflect more severe forms of active celiac disease, indicating a potential role of NT in intestinal inflammation."The suggestion, from Caroline Montén and colleagues , that the neuropeptide called neurotensin might play a role in paediatric coeliac disease is an interesting one that caught my eye recently. Interesting not only because of the potential implications for the archetypal 'gluten-causing' autoimmune condition cal........ Read more »

Why do more men die when they attempt suicide than women? The answer could lie in four traits, finds scientists. There are over 6,000 British lives lost to suicide each year, and nearly 75 per cent of those are male. However, research has found women are more likely to suffer from depression, and to attempt to take their own life.
