Abstract Background Borderline personality disorder (BPD) is a severe psychiatric with multiple psychopathological domains; so studying the correlation of clinical or behavioral data underlying structural and functional neurological findings in BPD focus interest recent years. The aim our study was to compare presence soft signs (NSS) patients borderline their normal controls, correlate severit...

Schizophrenia patients have higher scores on neurological soft-signs (NSS) and show greater deficits on a variety of neuropsychological tests than normal control subjects and mixed groups of psychiatric patients. Among chronic schizophrenia patients it is unclear which of these types of deficits most strongly differentiates patients who remain consistently symptomatic in spite of treatment with...

A subtle impairment of motor coordination and sensory integration functions is frequently found in schizophrenia. Clinically these deficits present as neurological soft signs (NSS). Because of its crucial role in motor function, control of muscle tone and equilibrium, the cerebellum is likely to be involved in the appearance of NSS. Magnetic resonance imaging (MRI) was performed in 30 patients ...

Among 16 chronic schizophrenic in-patients, all had at least one neurological soft sign (NSS), and 6 (40%) had definite neurodysfunction. NSS and TD scores were highly intercorrelated, and NSS were significantly correlated with neuroleptic drug exposure. NSS correlated positively with both positive and negative symptoms and cognitive impairment but not with cerebral ventricular size on CT. Pati...

A concept of an endophenotype, also termed as an internal endophenotype, is used in genetic studies on psychiatric disorders. Neurological soft signs are also considered candidates for endophenotypes of schizophrenia. Neurological soft signs are, objectively measured, non-localizing abnormalities, not related to impairment of a specific brain region, reflecting improper cortical-subcorical and ...
