Older Adults with Bipolar Disorder (OABD) represent a heterogeneous group, including those with early and late onset of the disorder. Recent evidence shows both groups have distinct clinical, cognitive, and medical features, tied to different neurobiological profiles. This study explored the link between polygenic risk scores (PRS) for bipolar disorder (PRS-BD), schizophrenia (PRS-SCZ), and major depressive disorder (PRS-MDD) with age of onset in OABD.

Genes discovered by previous epigenetic studies of schizophrenia have focused solely on diagnostics or pathology, potentially leading to a disconnection between them. Using these molecules to identify the disease is considered insufficient. MicroRNAs (miRNAs) binding to messenger RNAs (mRNAs) can lead to mRNA degradation, while circular RNAs (circRNAs), by binding to miRNAs as sponge, can reduce the inhibitory effect of miRNAs on mRNAs.

As many as one third of the patients diagnosed with schizophrenia do not respond to first-line antipsychotic medication. This group may benefit from the atypical antipsychotic medication clozapine, but initiation of treatment is often delayed, which may worsen prognosis. Predicting which patients do not respond to traditional antipsychotic medication at the onset of symptoms would provide fast-tracked treatment for this group of patients.
