What the study found
The review finds that oculomotor measures, event-related potentials, and cognitive deficits are supported as established endophenotypes for schizophrenia. Evidence for social cognition markers is more mixed, with Theory of Mind and emotion processing showing promise, but social perception and attributional bias remaining inconsistent.
Why the authors say this matters
The authors conclude that integrating these markers is relevant for stratified psychiatry and treatment personalization. They also suggest that some endophenotypes may reflect shared neural vulnerabilities across the schizoaffective spectrum.
What the researchers tested
The researchers conducted a narrative mini-review of recent evidence. They examined neurophysiological, neuropsychological, and social-cognitive parameters as candidate endophenotypes for schizophrenia, with endophenotypes defined as intermediate links between the disorder's polygenic architecture and clinical features.
What worked and what didn't
The review says there is ample evidence for oculomotor measures, event-related potentials, and cognitive deficits as endophenotypes found consistently in affected individuals and first-degree relatives. In social cognition, results are more heterogeneous: Theory of Mind and emotion processing appear promising, while evidence for social perception and attributional bias is inconsistent.
What to keep in mind
This is a narrative mini-review, so its conclusions depend on the studies it summarizes. The abstract notes that social cognition components still require further validation, and it does not provide detailed limitations beyond that.
