Abstract excerpt

METHODS: Eighty-five patients with mixed FND symptoms and 76 healthy control (HC) individuals were genotyped for 10 single-nucleotide polymorphisms (SNPs) in seven genes associated with the brain's stress response system. For genetic variants that were found to be linked to FND, associations with structural brain alterations were investigated by using a region-of-interest approach in a subset of FND patients with...
