A multicentre study on grey matter morphometric biomarkers for classifying early schizophrenia and parkinson's disease psychosis

Knolle, Franziska; Arumugham, Shyam S.; Barker, Roger A.; Chee, Michael W. L.; Justicia Díaz, Azucena; Kamble, Nitish; Lee, Jimmy; Liu, Siwei; Lenka, Abhishek; Lewis, Simon J. G.; Murray, Graham K.; Pal, Pramod Kumar; Saini, Jitender; Szeto, Jennifer; Yadav, Ravi; Zhou, Juan H.; Koch, Kathrin (Nature Research, 2023)

Psychotic symptoms occur in a majority of schizophrenia patients and in ~50% of all Parkinson's disease (PD) patients. Altered grey matter (GM) structure within several brain areas and networks may contribute to their ...
Altered subcortical emotional salience processing differentiates parkinson's patients with and without psychotic symptoms

Knolle, Franziska; Garofalo, S.; Viviani, R.; Justicia Díaz, Azucena; Ermakova, Anna O.; Blank, H.; Williams, G.B.; Arrondo, G.; Ramachandra, P.; Tudor-Sfetea, C.; Tudor-Sfetea, C.; Bunzeck, Nico; Düzel, Emrah; Robbins, T.W.; Barker, R.A.; Murray, Graham K. (Elsevier, 2020)

Objective: Current research does not provide a clear explanation for why some patients with Parkinson's Disease (PD) develop psychotic symptoms. The 'aberrant salience hypothesis' of psychosis has been influential and ...
Brain responses to different types of salience in antipsychotic naïve first episode psychosis: An fMRI study

Knolle, Franziska; Ermakova, Anna O.; Justicia Díaz, Azucena; Fletcher, Paul C.; Bunzeck, Nico; Düzel, Emrah; Murray, Graham K. (Nature Research, 2018)

Abnormal salience processing has been suggested to contribute to the formation of positive psychotic symptoms in schizophrenia and related conditions. Previous research utilising reward learning or anticipation paradigms ...
Default Mode Network Aberrant Connectivity Associated with Neurological Soft Signs in Schizophrenia Patients and Unaffected Relatives

Galindo Guarín, Liliana; Berge Baquero, Daniel; Murray, Graham K.; Mané Santacana, Anna; Bulbena Vilarrasa, Antonio; Pérez Solá, Victor; Vilarroya, Óscar (Frontiers, 2018)

Brain connectivity and neurological soft signs (NSS) are reportedly abnormal in schizophrenia and unaffected relatives, suggesting they might be useful neurobiological markers of the illness. NSS are discrete sensorimotor ...
