Sumario:The aim of the study was to compare the neurological soft signs (NSS) in schizophrenia patients with and without first rank symptoms (FRS), their first degree relatives (FDR), and normal controls. The study was conducted on 60 schizophrenia patients diagnosed according to ICD 10 DCR and categorized into groups with and without FRS using Schedules for Clinical Assessment in Neuropsychiatry, 30 FDRs of the study sample, and 30 normal controls matched for age, education, and handedness. All the subjects gave written informed consent. Scale for the Assessment of Positive Symptoms and Scale for the Assessment of Negative Symptoms were applied to have a comprehensive assessment of the symptoms. NSS were assessed using Extended Standard Neurological Assessment Instrument. The correlations between NSS and clinical symptoms were relatively modest but significant. There was a weak relation between NSS and positive symptom severity. The FDR of schizophrenia patients had significantly lower NSS scores than schizophrenia patients, but only FDR of schizophrenia patients without FRS had significantly higher scores than normal controls. Our results indicate that NSS are more prominent in schizophrenia patients with negative symptoms and support the theory of NSS being a trait marker of schizophrenia particularly in those without FRS.
