Polygenic effects on cortical size and ADHD converge on a mid-gestational progenitor-to-neuron transition programme

Neurodevelopmental and psychiatric conditions have long been hypothesised to emerge from changes in the structure and function of the brain. However, the molecular and cellular mechanisms linking brain structure to these conditions remain unknown. Here, using genetic and structural/diffusion neuroimaging data from 59,2...

712. Comorbid mental and substance use disorders – the role of genetic susceptibility

It is demonstrated that the relationship between alcohol use and psychiatric disorders is driven by a complex, shared genetic architecture rather than environmental complications alone and underscores the value of multi-ancestry and cross-disorder genetic studies in SUD.

Molecular Underpinnings of Retinal Traits 1 Shared with Major Psychiatric Disorders

Recent large-scale studies have enabled new knowledge about genetic underpinnings of morphological and electrophysiological alterations of the retina. Variation in retinal traits, often of neurodevelopmental origin, have been linked to major psychiatric disorders (MPDs). Here, we investigate the genetic overlap between...
