Is parental age difference important for offspring autism and schizophrenia risk?

by Paul Whiteley in Questioning Answers

In answer to the question that titles this post on whether parental age differences at offspring conception might matter when it comes to offspring risk of autism or schizophrenia, the answer is very possibly. As the paper by Byars & Boomsma [1] (open-access) reports: "Our study shows that autistic and schizophrenic disorder risks tend to be higher, in more dissimilarly aged parents, relative to parents with the most similar ages." This age disparity issue has been mentioned previously in th........ Read more »

Mental illness genetically linked to drug use and misuse

by Dr. Jekyll in Lunatic Laboratories

There are many reports of drug use leading to mental health problems, and we all know of someone having a few too many drinks to cope with a bad day. Many people who are diagnosed with a mental health disorder indulge in drugs, and vice versa. As severity of both increase, problems arise and they become more difficult to treat. But why substance involvement and psychiatric disorders often co-occur is not well understood.

Omega-3 and omega-6 polyunsaturated fatty acids and bipolar disorder

by Paul Whiteley in Questioning Answers

"Biomarker studies of PUFA [polyunsaturated fatty acid] and treatment studies of n-3 [omega-3] PUFA in bipolar disorder show promise for indicating a way forward in the study of PUFA in bipolar disorder."I don't want to labour any points raised by the review of studies published by Erika Saunders and colleagues [1] looking at fatty acids and bipolar disorder but there does seem to be a familiar ring to the current evidence base on how for at least 'some' cases of bipolar diso........

Scientists find new path in brain to ease depression

by Dr. Jekyll in Lunatic Laboratories

Scientists have discovered a new pathway in the brain that can be manipulated to alleviate depression. The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed. New antidepressant options are important because a significant number of patients don't adequately improve with currently available antidepressant drugs.

"a low prevalence of definite pathology in children with autism spectrum disorder undergoing brain MRI"

by Paul Whiteley in Questioning Answers

The quote: "a low prevalence of definite pathology in children with autism spectrum disorder undergoing brain MRI [magnetic resonance imaging]" heading up today's post is taken from the paper by Alison Cooper and colleagues [1] who among other things, examined whether MRI picked up anything 'useful' when it came to autism / autism spectrum disorder (ASD) in their cohort. MRI, by the way, refers to the fantastic imaging technology that provides those rather detailed pictures of our inner bod........ Read more »

Revising the meaning of 'prion'

by Dr. Jekyll in Lunatic Laboratories

A team of scientists are redefining what it means to be a prion--a type of protein that can pass heritable traits from cell to cell by its structure instead of by DNA. Although prions are infamous for causing Creutzfeldt-Jakob disease, fatal familial insomnia, and bovine spongiform encephalopathy, commonly known as mad cow's disease, the present study indicates that prions identified in yeast, and possibly in plants, and other organisms may be beneficial.

Humour training for autism - is it needed and is it useful?

by Paul Whiteley in Questioning Answers

Can we and should we formally 'teach' humour to people diagnosed on the autism spectrum? Indeed, do we actually need to?Yes said the results of the study published by Ching-Lin Wu and colleagues [1] although I personally am not so impressed.Discussing how their results "supported the effectiveness of the 15-hour training" regime, Wu et al report that for a small group of adolescents diagnosed with an autism spectrum disorder (ASD) "and average intelligence" moves to implement "a humor-knowl........

For women, caffeine could be ally in warding off dementia

by Dr. Jekyll in Lunatic Laboratories

Among a group of older women, self-reported caffeine consumption of more than 261 mg per day was associated with a 36 percent reduction in the risk of incident dementia over 10 years of follow-up. This level is equivalent to two to three 8-oz cups of coffee per day, five to six 8-oz cups of black tea, or seven to eight 12-ounce cans of cola.

The physical health of adults with autism

by Paul Whiteley in Questioning Answers

Another short post today opening with the conclusion reached in the paper by Andrew Cashin and colleagues [1]: "From the findings, it can be stated with confidence that people with ASD [autism spectrum disorder] have a high rate of comorbidity and increased risk for chronic disease."Yes, not new news to many that physical health is generally 'under-rated' when it comes to adult autism (see here and see here for examples). The question remains however: what are we all going to........ Read more »

One of the best articles to discuss suicide risk and autism so far...

by Paul Whiteley in Questioning Answers

I'm cheating a little bit today as minus too much critical commentary or discussion, I'm drawing your attention to the paper by Tony Salvatore and colleagues [1] (open-access) on a most important topic: suicide risk and autism.Written by authors who between them seem to know quite a bit about autism and also managing suicide prevention particularly under crisis conditions, I reckon this review article is one of the best we have so far in this area. I say that on the basis that not only are estim........ Read more »

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

"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........

The Adult Psychiatric Morbidity Survey (APMS) 2014 and autism

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

by William Yates, M.D. in Brain Posts

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 ........

Postural tachycardia syndrome and gluten?

by Paul Whiteley in Questioning Answers

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. As well as being quite prevalent in a c........ Read more »
