The association between cytokines and psychomotor speed in a spectrum of psychotic disorders: A longitudinal study
Larsen, Jeanette Brun; Reitan, Solveig Merete Klæbo; Løberg, Else-Marie; Rettenbacher, Maria; Bruserud, Øystein; Larsen, Tor Ketil; Anda, Liss Gøril; Bartz-Johannessen, Christoffer; Johnsen, Erik; Kroken, Rune Andreas (Peer reviewed; Journal article, 2021)Background In schizophrenia, impaired psychomotor speed is a common symptom predicting worse functional outcome. Inflammation causes changes in white matter integrity, which may lead to reduced psychomotor speed. Therefore, ... -
