Nov. 23 (UPI) — Researchers said Wednesday they found changes in almost all the regions of the brain they investigated via MRI scan data of children with attention-deficit/hyperactivity disorder.

Children with ADHD had abnormal connectivity in the brain networks involved in memory processing and auditory processing, a thinning of the brain cortex, and significant white matter microstructural changes, especially in the frontal lobe of the brain.

The results of the new research on brain biomarkers of ADHD — based on analysis of data from MRI exams of 7,805 children — is scheduled to be presented Sunday at the annual meeting of the Radiological Society of North America.

Animal studies have shown that pregnancy is associated with unique changes in the mammalian brain and behaviour, although pregnancy-associated changes in the human brain are less well studied. Here the authors show that pregnancy is associated with changes in resting state brain activity and brain anatomy which are most pronounced in the default mode network.

Imagine that you can grow a clone with the level of intelligence below the level of a turkey or a chicken with the perfectly-exercised body. Would you consider swapping your brain with this perfect and unconscious clone? Surprisingly, many professionals would not even think twice.

Successful communication and cooperation among different members of society depends, in part, on a consistent understanding of the physical and social world. What drives this alignment in perspectives? We present evidence from two neuroimaging studies using functional magnetic resonance imaging (fMRI; N = 66 with 2,145 dyadic comparisons) and electroencephalography (EEG; N = 225 with 25,200 dyadic comparisons) to show that: the extent to which people’s neural responses are synchronized when viewing naturalistic stimuli is related to their personality profiles, and that this effect is stronger than that of similarity in gender, ethnicity and political affiliation.

Major depressive disorder is associated with altered interoception — or the ability to sense the internal state of your body. Now, new brain imaging research provides evidence that depressed individuals tend to exhibit “faulty” neural processing of gastric interoception, particularly among those with high levels of rumination. The findings have been published in the Journal of Psychiatric Research.

“Repetitive negative thinking (RNT), usually referred to as ‘rumination’ in persons who suffer from depression, is a very significant clinical problem,” explained study author Salvador M. Guinjoan, a principal investigator at the Laureate Institute for Brain Research and associate professor at Oklahoma University Health Sciences Center at Tulsa.

“The reason is that when it is severe and persistent, RNT conditions higher chances of depression relapse and is associated with residual symptoms after treatment, is more common in persons who do not respond to treatment, and is even related to suicide. This particular communication refers to one among a series of projects in our lab attempting to understand rumination.”

The discovery could lead to potential future targeted therapies and treatments for this brain disorder.

Researchers have found two novel genes that increase an individual’s risk of developing Alzheimer’s disease (AD). This disorder is the leading cause of dementia and has an estimated heritability —genetic factor causing variation in the population, or an inherited trait— of 70%.

Summary: Researchers have identified two new genes, ATP8B4 and ABCA1, that are implicated in Alzheimer’s disease. The genes impact the brain’s immune system and cholesterol processing, leading to an increased risk of developing Alzheimer’s disease.
