Analysis of shared heritability in common disorders of the brain
It is demonstrated that, in the general population, the personality trait neuroticism is significantly correlated with almost every psychiatric disorder and migraine, and it is shown that both psychiatric and neurological disorders have robust correlations with cognitive and personality measures.
Genome-wide association studies establish that human intelligence is highly heritable and polygenic
A genome-wide analysis of unrelated adults with data on single nucleotide polymorphisms and detailed phenotypes on cognitive traits unequivocally confirms that a substantial proportion of individual differences in human intelligence is due to genetic variation, and is consistent with many genes of small effects underlying the additive genetic influences on intelligence.
Genome-wide association meta-analysis in 269,867 individuals identifies new genetic and functional links to intelligence
A large-scale genetic association study of intelligence identifies 190 new loci and implicates 939 new genes related to neurogenesis, neuron differentiation and synaptic structure, a major step forward in understanding the neurobiology of cognitive function as well as genetically related neurological and psychiatric disorders.

The overall prevalence of psychiatric disorders in children is relatively low in this Norwegian sample, when assessed with the Development and Well-Being Assessment.
Study of 300,486 individuals identifies 148 independent genetic loci influencing general cognitive function
A genome-wide association study for general cognitive function in 300,486 individuals is performed and genetic loci that implicate neural and cell developmental pathways in this trait are identified.

The results demonstrate a negative relation between use of technology and sleep, suggesting that recommendations on healthy media use could include restrictions on electronic devices.
Genetic contributions to variation in general cognitive function: a meta-analysis of genome-wide association studies in the CHARGE consortium (N=53 949)
In hypothesis-driven tests, there was significant association between general cognitive function and four genes previously associated with Alzheimer’s disease: TOMM40, APOE, ABCG1 and MEF2C.

Findings are consistent with the concept of autism as a spectrum, and large differences across informants suggested the need to gather information both from families and from schools when screening for autism spectrum disorders.
Impairment across executive functions in recurrent major depression
The depressed patients with moderate to severe recurrent major depressive disorder were mildly impaired across a wide range of EFs, which may have a negative impact on everyday functioning for this group of patients.
Sleep patterns and insomnia among adolescents: a population‐based study

It is concluded that short sleep duration, long sleep onset latency and insomnia were prevalent in adolescents, and warrants attention as a public health concern in this age group.
