Table: Results of gene analysis (top 20 genes)
from GWAS meta-analysis reveals novel loci and genetic correlates for general cognitive function: a report from the COGENT consortium

Findings could lead to new treatments for schizophrenia, ADHD etc. An international team of scientists, led by Todd Lencz, PhD, professor at The Feinstein Institute for Medical Research at Northwell Health and Hofstra Northwell School of Medicine, have unlocked some of the genes responsible for cognitive ability. Dr. Lencz et al studied the genes of 35,000 people and discovered new genetic variations related to cognitive ability.

60 international scientists form the Cognitive Genomics Consortium (COGENT)...

Stimulation of Dorsolateral Prefrontal Cortex Enhances Adaptive Cognitive Control: A High-Definition Transcranial Direct Current Stimulation Study Oyetunde Gbadeyan, Katie McMahon, Marco Steinhauser and Marcus Meinzer Journal of Neuroscience 14 December 2016, 36 (50) 12530-12536; DOI: https://doi.org/10.1523/JNEUROSCI.2450-16.2016

A cutting edge, non-invasive brain stimulation technique could improve cognitive control for people with conditions such as schizophrenia and autism, ADHD. Researchers at The University of Queensland’s Centre for Clinical Research have found the technique – which applies high-definition transcranial direct current stimulation to a particular area of the brain – improves cognitive and conflict control.

PhD candidate Oyetunde Gbadeyan said the study provides th...

Those mothers who had taken Vitamin D, and had a vitamin D level (25OHD) in their umbilical blood over 25 nmol/L, had children with lower ADHD score

Children of mothers who took vitamin D during pregnancy with resultant high levels of the vitamin in the umbilical blood have fewer symptoms of ADHD at the age of 2½ years. “And for every 10 nmol/L increase in the vitamin D concentration in umbilical blood, the risk of a being among the 10% highest score on the ADHD symptom scale fell by 11%,” explains one of the study’s initiators, Professor Niels Bilenberg.

1,233 children from Odense Municipality were monitored in the study. Vitamin D was measured in umbilical blood, and mothers completed the Child Behavior Checklist (CBCL) when their child was 2½ years old...

Studies of children and adolescents have associated excess manganese in the diet with attention deficits, but confounding factors in those studies have made it impossible to show a cause and effect relationship. The new study is the first to establish a causal link between exposure to elevated manganese in the diet and attentional dysfunction in an animal model.

Manganese is an essential element, required by the body in trace amounts. High levels of exposure can have neurotoxic effects, however, leading to a condition called “manganism” in adults exposed to manganese dust or fumes in mining, welding, and other industrial occupations...
