Course of neurological soft signs in first-episode schizophrenia: Relationship with negative symptoms and cognitive performances
This prospective study examined the course of neurological soft signs (NSS) in patients with first-episode schizophrenia and its relationship with negative symptoms and cognitive functions. One hundred and forty-five patients with first-episode schizophrenia were recruited, 29 were classified as having prominent negative symptoms.

It is generally accepted that NSS are more prevalent in schizophrenia patients, including first -episode cases, than in healthy subjects.

متن کاملCerebellar substructures and neurological soft signs in first-episode schizophrenia.
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 ...
متن کاملNeurological soft signs and brain morphology in first-episode schizophrenia.
BACKGROUND Although minor motor and sensory deficits, or neurological soft signs (NSS), are a well-established finding in schizophrenia, the cerebral changes underlying these signs are only partly understood. We therefore investigated the cerebral correlates of NSS by using magnetic resonance imaging (MRI) in patients with schizophrenia and healthy controls. METHOD Forty-two patients, all rec...
