Profound cognitive deficits are a common feature of schizophrenia, and substantial
impairments are also seen in bipolar disorder (BD) and major depressive disorder,
albeit less frequently recognized. These impairments span the range of fluid intelligence
functions, with the most severe tending to be in processing speed, working and episodic
memory, and executive functioning, and can affect crystallized intelligence by reducing
educational attainment. Cognitive deficits are highly correlated with impairments
in the ability to perform everyday tasks, called functional capacity, affecting independence
in residence, social capability, and employment, and thus directly contribute to the
disability associated with these disorders.

- PreviewCognitive impairment is a key feature of psychiatric illness, making cognition an important tool for exploring of the genetics of illness risk. It remains unclear which measures should be prioritized in pleiotropy-guided research. Here, we generate profiles of genetic overlap between psychotic and affective disorders and cognitive measures in Caucasian and Hispanic groups.
