Brief Summary: Patients with schizophrenia have volume loss in gray matter This study is designed to evaluate whether their is microglia activation in schizophrenia using 11CR-PK11195 PET
Detailed Description: Schizophrenia is a complex and chronic disease that affects different aspects of cognition and behaviour including attention perception thought processes emotion and volition Schizophrenia is a brain disease particularly involving decrement in gray matter as has been supported by findings from many imaging studies The pathophysiology of these gray matter changes has not been clarified Microglia activation is the consequence of virtually all conditions associated with neuronal injury When activated following neuronal damage microglia show a marked increase in the expression of peripheral type benzodiazepine binding sites which are particularly abundant on cells of the mononuclear macrophage

R-PK11195 1-2-chlorophenyl-N-methyl-N-11-methylpropyl-3 isoquinolinecarboxamide is a highly selective ligand for the peripheral benzodiazepine binding site R-PK11195 labelled with the positron emitter carbon-11 can be used to monitor the peripheral type benzodiazepine receptors using Positron Emission Tomography PET At the Vrije Universiteit Medical Centre R-11CPK11195 is used for studying microglia activation in-vivo in patients with traumatic brain damage minimal cognitive impairment and Alzheimer disease

The objective of this study is to determine whether and to what extent microglia activation occurs in schizophrenia Ten patients with schizophrenia will be recruited and 10 controls matched for age and gender This is an open study The study consists of one PET scan which will be performed at the Clinical PET Centre of the Vrije Universiteit Medical Centre All subjects will also get a MRI scan which will be performed at the department of Radiology University Medical Centre Utrecht
