Autistic and Catatonic Spectrum Symptoms in Patients with Borderline Personality Disorder.

The total CS score was significantly higher in the BPD and MDD groups than in the CTL group, while the majority of CS domain scores were significantly higher in the BPD group than in the MDD group, which scored significantly higher than the CTL group. The total AdAS Spectrum score and the AdAS Spectrum domain scores were significantly higher in the BPD group than in the MDD group, which in turn scored significantly higher than the CTL group. The CS domains "psychomotor activity" and "impulsivity", and AdAS Spectrum domains "verbal communication", "empathy", and "hyper-/hyporeactivity to sensory input" were associated with the risk of presenting a diagnosis of BPD.
