Schizophrenia synaptic loss is left-biased, follows brain's molecular wiring, and starts in left frontal lobe
↗
PET imaging shows schizophrenia involves widespread synaptic loss that is left-biased, follows the brain's molecular and connectivity architecture, and may start in a left frontal lobe.
Schizophrenia gives researchers a concrete target for intervention, suggesting synaptic loss is not random but tied to the brain's chemistry and wiring. For engineers, it shows that PET-based synaptic density mapping can reveal disease patterns that differ from MRI volume changes, and that structural connectivity models can predict where pathology begins.

PET scans of 122 people, including 29 with schizophrenia, showed widespread synaptic loss in frontal, temporal, and memory/emotion regions.
Synaptic loss was considerably greater on the left side of the brain than the right.
Computer simulations using structural connections identified a left frontal lobe area as a likely starting point for the spread of synaptic loss.
