OBJECTIVE The use of endophenotypes, such as neurological soft signs (NSS), is advocated as one possible method to elucidate the heterogeneity of schizophrenia. Exploring the associations between NSS and specific illness symptoms has revealed some trends, although results have been conflicting. To date, such studies have been conducted largely on Caucasian populations and our pilot study repres...

The soft neurological signs (SNS) and minor physical anomalies (MPA) were studied in 107 adult schizophrenics. The sample consisted chronic (N=60) and acute (N=47) schizophrenic subtypes. The SNS were found more in chronic patients (p< .01). The most prevalent abnormalities in SNS were related to the sensory integration and motor co-ordination. The release reflexes were rare though they were en...

BACKGROUND Neurological soft signs (NSS) are hypothesized as candidate endophenotypes for schizophrenia, but their prevalence and relations with clinical and demographic data are unknown. The authors undertook a quantification (meta-analysis) of the published literature on NSS in patients with schizophrenia and healthy controls. A systematic search was conducted for published articles reporting...

OBJECTIVE Neurological soft signs are very common in children with the attention deficit hyperactivity disorder (ADHD), and the first line medication of this disorder is methylphenidate. The aim of the study was to assess the effect of methylphenidate on the neurological soft signs in children and adolescents suffering from ADHD depending on the dose of methylphenidate. METHODS Thirty five pa...

OBJECTIVE Neurological soft signs are frequently found in schizophrenia. They are indicators of both genetic liability and psychopathological symptoms. To further differentiate "trait" and "state" relations the authors compared the 1-year course of neurological soft signs in schizophrenia patients and comparison subjects. METHOD Thirty-nine patients with first-episode schizophrenia spectrum d...

OBJECTIVE The primary objective of this study was to examine neurological soft signs in patients with obsessive-compulsive disorder compared with patients with schizophrenia and a control group in the Indian setting. The secondary objective was to find any correlation between age at onset and neurological soft signs scores, as well as that between severity of obsessive-compulsive disorder sympt...

A prospective study was undertaken in fifty patients who were diagnosed to have major affective disorder, to assess the prevalence of neurological soft signs, their localization and their correlation with response to treatment. Neurological soft signs have been shown to be very common in major affective disorder. They were mainly localized in the temporal and parietal lobes. There was no differ...

BACKGROUND Soft neurological signs are minor, non localizing, objective abnormalities, thought to reflect damage in cortical and sub-cortical connections or connections within different cortical regions. Regional structural grey matter anomalies have already been observed and correlated with the presence of cognitive deficits and presence of soft neurological signs in schizophrenic patients. ...
