In recent decades, a growing
number of structural neuroimaging studies
of grey matter (GM) in trigeminal neuralgia (TN) have reported inconsistent
alterations. We carried out
a systematic
review and meta-analysis to identify consistent and replicable GM
volume abnormalities in TN patients. Our findings provide a
thorough profile of GM volume alterations in TN patients and
constitute robust evidence that aberrant GM volumes in the brain regions
regulating and moderating sensory-motor and affective processing may play an
important role in the pathophysiology of TN.
