TL;DR: A genome-wide association study of lithium response in 2,563 patients collected by 22 participating sites from the International Consortium on Lithium Genetics (ConLiGen); the largest attempted so far finds a single locus of four linked SNPs on chromosome 21 met genome- wide significance criteria for association with lithium response.

TL;DR: Evidence is provided for a negative association between high genetic loading for SCZ and poor response to lithium in patients with BPAD, suggesting the potential for translational research aimed at personalized prescribing of lithium.
Journal ArticleDOI
Longitudinal clinical course following pharmacological treatment of methamphetamine psychosis which persists after long-term abstinence.
TL;DR: The results suggest that both psychotic and affective symptoms are involved in therapeutic response and prognosis of METH psychosis, and three groups of patients showed apparent differences in prognoses during pharmacological treatment.
