Reduced left amygdala volume in patients with dissociative seizures (psychogenic nonepileptic seizures)

PurposeThis study specifically investigated differences of amygdalar and hippocampal volumes between patients with dissociative seizures (DS), mesial temporal lobe sclerosis (MTS), and normal controls (NC).MethodsBetween 2003 and 2018, 127 patients diagnosed with DS and 278 with MTS were recruited.
