A study using transcranial magnetic stimulation to investigate motor mechanisms in psychomotor retardation in depression.
The pathophysiological basis of psychomotor retardation in depression is unclear. In this study, transcranial magnetic stimulation (TMS) was used to examine the functioning of the motor cortical system in 19 depressed patients and 10 healthy control subjects. Motor-evoked potentials were measured in the biceps brachii muscle during a series of tests with the muscle at rest and during voluntary ...
متن کاملNeurological Soft Signs in First -Episode Schizophrenia
Neurological soft signs (NSS) refer to subtle neurological abnormalities comprising deficits in sensory integration, motor coordination, or sequencing of complex motor acts. It is generally accepted that NSS are more prevalent in schizophrenia patients, including first -episode cases, than in healthy subjects. Moreover, NSS have been consistently demonstrated in neuroleptic naïve firstepisode p...
متن کاملPotential endophenotype for schizophrenia: neurological soft signs.
INTRODUCTION Neurological soft signs (NSS) are suggested as a candidate endophenotype for schizophrenia. This article aims to review relevant literature and discuss the role of NSS in understanding schizophrenia. METHODS This is an update on a review article published in 2003. Articles from 2003 onwards were specifically reviewed and discussed with relevance to the role of NSS as endophenotyp...
متن کاملTranscranial magnetic stimulation for schizophrenia.
This is the protocol for a review and there is no abstract. The objectives are as follows: To estimate the effects of TMS alone compared with sham TMS or with 'standard management' and any other comparison interventions in reducing psychotic symptoms associated with schizophrenia.
متن کاملTranscranial Magnetic Stimulation and Schizophrenia
Electrical current flowing through a coil induces a magnetic field. This is the basis for MRI, a technology that has been groundbreaking in furthering our understanding of the human brain with respect to structure and function. Correspondingly, changes in magnetic fields can also induce electrical currents. When applied in proximity to live brain tissue, alternating magnetic fields can induce e...
