Without trying to scaremonger, it is already well known that certain anti-psychotics potentially indicated for some of the more 'challenging behaviours' associated with conditions like autism for example, carry their own important side-effects. Risperidone, one of the more commonly used medicines, has quite an extensive list of possible side-effects, some of which have been previously mentioned on this blog (see here). Increased appetite and weight gain are some of the more commonly observed sid........ Read more »

I'd like to start by making one thing abundantly clear about today's post: I am not insinuating that self-injurious behaviour (SIB) accompanying autism is solely under genetic (or epigenetic) control.As I've discussed before on this blog, there are potentially many, many reasons why SIB under the umbrella of the so-called 'challenging behaviours' occurs (see here). As and when it does happen, the onus is on those significant others to turn detective before anyone immediately reaches for somethin........ Read more »

When most of us think maggots, we probably don’t think anything good, but maybe we should start. In a proof-of-concept study, researchers have shown that genetically engineered green bottle fly (Lucilia sericata) larvae can produce and secrete a human growth factor – a molecule that helps promote cell growth and wound healing.

Last month, we spoke of our vision of the future of humanity here at the lab. It makes sense that humanity would one-day step away from the static, non-living computer constructs we have designed. Moving us instead towards an organic alternative, one that can be readily repaired, replaced, or changed. While we cannot pretend to know what the future may hold, a new discovery helps bolster the stance we presented.

'The disrupted connectivity hypothesis of autism spectrum disorders: Time for the next phase in research' went the title of the paper by Roma Vasa and colleagues .Disrupted connectivity by the way, refers to the idea that "deficiencies in the way the brain coordinates and synchronizes activity amongst different regions may account for the clinical symptoms of ASD [autism spectrum disorders]."

In today’s lexicon, the term mental illness is used pretty widely. It can be used to describe someone suffering from depression, to PTSD, to even someone suicidal. In fact, today it is sort of a catch all term for anyone who is involved in a mass shooting here in the US. We are getting off […]... Read more »

I'm a fan of the idea that the categorical labelling system currently used in psychiatric and psychological circles probably isn't fit for purpose these days. Y'know, the idea that compartmentalising people into diagnostic boxes with an overarching title whilst useful for general identity and statistical classification, does little to inform about individual experiences or the important cross-over in presentation between and across different labels. Don't even get me started on how the use of su........ Read more »

It was a clear case of a false alarm, toxoplasmosis, a parasite that infects mice and cats was thought to have an effect on humans. However, after a thorough review of the data it was off the hook, or so we thought. Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis.

"The present study shows that intragastric treatment of mice with an antibiotic mix impairs novel object recognition, but not spatial memory.

Think your DNA is all human? Think again. And a new discovery suggests it’s even less human than scientists previously thought. Nineteen new pieces of non-human DNA — left by viruses that first infected our ancestors hundreds of thousands of years ago — have just been found, lurking between our own genes.

Some poisons are better known than others.Arsenic, for example, is famous for its participation in many a murder and suicide from the Middle Ages through to the mid-19th century (after which it became easier to detect and more difficult to acquire). Even to this day, the malicious metalloid remains in the public eye as a contaminant of groundwater in parts of South Asia and of soil in old orchards.A decidedly more obscure poison is a gooey industrial derivative of coal tar (leftovers from conver........

Why humans and other animals sleep is one of the remaining deep mysteries of physiology. One prominent theory in neuroscience is that sleep is when the brain replays memories "offline" to better encode them ("memory consolidation"). A prominent and competing theory is that sleep is important for rebalancing activity in brain networks that have been perturbed during learning while awake.

A new study is the first to report that the relationship between nightmares and suicidal behaviors is partially mediated by a multi-step pathway via defeat, entrapment, and hopelessness. Results show that suicidal thoughts, plans or attempts were present in 62 percent of participants who experienced nightmares and only 20 percent of those without nightmares.

Traumatic brain injury (TBI), also known as intracranial injury, is a substantial head injury that results in damage to the brain. This damage can cause a wide spectrum of possible health outcomes. Factors that are likely to influence neuropsychiatric outcome in TBI can be classified as pre-injury, injury and post-injury factors. Injury-related factors include a) the type of physical injury

They say that once you’ve learned to ride a bicycle, you never forget how to do it. Unfortunately for students who hope this applies to studying, they might not like new research suggesting that while learning, the brain is actively trying to forget. While this may at first blush seem like a bad thing, it actually may be useful for those suffering from PTSD.
