abstract = {Patients with autoimmune encephalitis - who often have
accompanying psychiatric symptoms - frequently have
electroencephalography (EEG) changes and normal conventional
magnetic resonance imaging (MRI) findings. The aim of this
paper was to analyze automated EEG and morphometric MRI
findings in psychiatric patients with suspected autoimmune
psychosis (AP) spectrum syndromes versus controls and the
correlation of MRI measures with EEG, cerebrospinal fluid
(CSF), and psychometric/neuropsychological findings.In
total, forty patients were included. Suspected AP spectrum
syndromes were defined broadly based on the autoimmune
psychiatric syndrome concept. All patients showed signs of
an autoimmune process. That is, upon further diagnostic
testing, they tested at least positive for
well-characterized neuronal antibodies, novel central
nervous system antibodies, or well-characterized systemic
antibodies with brain involvement. For EEG, thirty-seven
matched patient-control pairs, and for structural MRI,
thirty-five patients and matched controls, were available.
EEG analysis for intermittent rhythmic delta/theta activity
(IRDA/IRTA) was performed using independent component
analysis. MRI scans were analyzed using FreeSurfer (7.2) for
the subcortical measures and CAT12 for cortical thickness
and global volumes.Patients did not show significantly
increased IRDA/IRTA rates. Regarding brain volumes, there
was a significant decrease in grey matter volume/total
intracranial volume (TIV) (p=0.027) and a significant
increase in CSF/TIV (p=0.027), which remained significant
after correction for multiple comparisons. Further
differences with lower white matter volume/TIV, reduced
cortical thickness in the left parahippocampal and
transversotemporal gyri and an increase in the volume of the
left lateral ventricle of patients did not remain
significant after correcting for multiple testing. White
blood cell counts in the CSF of the whole patient group
correlated positively with increased hippocampal volumes.
Brain volumes did not correlate with psychometric scales,
but with several neuropsychological
scores.Autoantibody-associated suspected AP spectrum
syndromes seem to be associated with slight global grey
matter volume reductions and secondary increased CSF
volumes. Associations between hippocampal volume increases
and inflammatory CSF markers could, in contrast, reflect
edematous swelling within the limbic system. Further
multimodal imaging studies of more homogeneous AP groups
might be promising to detect morphometric correlates.},
