Do you know the feeling of a musical piece moving you? What is this feeling? One common answer by psychological researchers is that what you feel is your attention moving in sync with the music. In a new paper I show that this explanation is mistaken. Watch the start of the following video and observe […]... Read more »

It's been a while since I've talked about Toxoplasma gondii on this blog; the parasite that more than most, has been linked with all-manner of different psychiatric labels (see here for example). Although still the topic of some discussion, I'm swayed towards the possibility that there may be some important *associations* to be seen when it comes to this survivor and human behaviour(s) outside of just making rats attracted to cat urine (see here) to improve reproduction chances.Indeed, in t........

"ADHD [attention-deficit hyperactivity disorder] patients were overrepresented in the group with low levels of some vitamins, possibly indicative of inadequate dietary intake of these micronutrients in a subgroup of patients. It is important to identify these patients in dietary intervention trials of ADHD."So said the study findings reported by Elisabeth Toverud Landaas and colleagues  (open-access) providing some potentially important data on how nutritional factors might int........

It is very cold outdoors (even in Texas) and it is time once again for a number of important things we decided did not merit an entire post but wanted to share. Think of it as a series of holiday gifts for you… Ever wonder why white-collar criminals did what they did? Wonder no more. […]... Read more »

"To conclude, the evidence from the studies allows us to conclude that there is an association between PM [particulate matter] exposure and ASD [autism spectrum disorder] whose strength varies according to the particle size studied with the association with PM2.5 and diesel PM being stronger."Although probably not great sentence structure to begin a post with a conclusion, the 'bottom line' reported by María Morales-Suárez-Varela and colleagues  summarises the curre........

"Our data show there may be a specific subtype of ASD [autism spectrum disorder] linked to comorbid psychosis. The results support findings that psychosis in people with ASD is often atypical, particularly regarding affective disturbance."So said the findings reported by Felicity Larson and colleagues  (open-access available here) who bring an important topic into view that has recently been raised in the media too (see here). I appreciate that to talk about yet more comorbidity pot........ Read more »

We’ve seen the reports of hate crimes skyrocketing—both in general, and specifically for Muslims. Now a new report says the self-reports of discrimination from Latinos have doubled in the past decade. The study used data from the National Latino Health Care Survey (a telephone survey of 800 Latino adults completed in 2013). The lead author […]... Read more »

"Our findings identify distinctive mucosal microbial signatures in ASD [autism spectrum disorder] children with FGID [functional gastrointestinal disorders] that correlate with cytokine and tryptophan homeostasis."So said the study results published by Ruth Ann Luna and colleagues  who "compared mucosa-associated microbial communities in children with ASD to previous reports characterizing stool in this population" among other things.

"Consistent with the previous findings, [the] rate of suicidality is higher in individuals with ASD [autism spectrum disorder]."That was one of the conclusions reported in the paper by Sevcan Karakoç Demirkaya and colleagues  (open-access) yet again touching on a most important topic when it comes to autism, particularly the part of the autism spectrum labelled as 'high-functioning'. Personally, I'm not a great fan of the 'functioning' description typically added to autism to ........ Read more »

Time flies! Once again, I'm posting my annual 'state of the science' autism research review, this time covering the particularly unusual year of 2016.With around 300 blog entries to choose from, I'm changing the format this year to list a 'top 5' of areas where I think some scientific progress has been made. The caveat as ever being that there are still mountains to climb in terms of delineating aetiology, nature and importantly, how one can actually improve quality of life for those on the........

With the pinnacle of the season of 'jolly' almost upon us, I'd like to make some brief discussion on the findings reported by Denise Rogers and colleagues  and specifically the observation that: "ADHD [attention-deficit hyperactivity disorder] symptoms were significantly greater in the CFS [chronic fatigue syndrome] group than in HC [healthy controls]."With the aim of examining both the prevalence of fatigue in cases of ADHD and the prevalence of ADHD symptoms in adults wi........

"Some psychosis cases an 'immune disorder'" went the BBC headline with reference to the paper by Belinda Lennox and colleagues  talking about the detection of antibodies against the N-methyl-D-aspartate receptor (NMDAR) in cases of first-episode psychosis (FEP).Although by no means a universal phenomenon, researchers reported that 3% of their 228 participants diagnosed with FEP who provided a blood sample showed the presence of NMDAR antibodies compared with none of the healthy controls ........

"New form of autism found" went one of the headlines reporting on the paper by Dora C. Tărlungeanu and colleagues  and findings that "elucidate a neurological syndrome defined by SLC7A5 mutations and support an essential role for the BCAA [branched-chain amino acids] in human brain function." This work continues a rather important research story talking about how one 'type' of autism might have some important roots in relation to the branched-chain amino acids and their m........

Want to know if someone is interested? Watch their pupils
The pupils are among those parts of body languages that are not in our conscious control. White and Maltzman (1977) found that the pupil starts dilating when a person shows interest in some other person he or she talking to.

"Gestational vitamin D deficiency was associated with autism-related traits in a large population-based sample. Because gestational vitamin D deficiency is readily preventable with safe, cheap and accessible supplements, this candidate risk factor warrants closer scrutiny."So said the findings reported by Vinkhuyzen and colleagues  (open-access) reporting on data derived from "the Generation R Study, a population-based prospective cohort from fetal life onward, based in Rotterdam, The Netherl........

While you may think you have heard this line recently, this is really (based on new research) what most of us think about ourselves.

The disturbingly accurate brain science that identifies potential criminals while they’re still toddlers... scientists are able to use brain tests on three-year-olds to determine which children are more likely to grow up to become criminals.
