Epidemiological studies have displayed extremely varying NIP prevalence rates in schizophrenic patients, ranging from 5% to 90%.1,3 On the other hand,

studies in first-episode neuroleptic-naive patients have revealed that psychomotor disturbances are also present, at, the onset of illness, as well as in clinically unaffected relatives of schizophrenic patients.4 Psychomotor disturbances in unmedicated schizophrenics have been interpreted as manifestations of dysfunctional neural connections between subcortical and cortical areas, or of defective brain structures.5-7 Gupta et al made the point, Inhibitors,research,lifescience,medical that neurological abnormalities in schizophrenic patients may be present independently of side effects of medication, but that, antipsychotics do contribute to their prevalence.5 Motor disturbances and Inhibitors,research,lifescience,medical subjective well-being In schizophrenia, the subjective well-being of the patients may

not only be affected by the disabling symptoms of the disorder, but also by side effects of the antipsychotic treatment. Antipsychotic treatment has been associated with a variety of motor side effects, as well as affective, BI-D1870 clinical trial cognitive, and social impairments, which can reduce quality of life.8-12 Motor disturbances are associated with a substantial reduction in the patient’s quality of life and in compliance with the treatment. Van Puttcn Inhibitors,research,lifescience,medical found a significant, relationship of noncompliance with motor side effects, particularly with akathisia.13 In this context, we assessed the correlations of subjective well-being with objectively measured gait, parameters, expert-rated motor disturbances, and psychopathological status in conventionally treated, atypically treated, Inhibitors,research,lifescience,medical and drug-naïve patients.14 The main variables were the SWN (Subjective Well-being under Neuroleptic Treatment Scale) scores,15 the ESRS (Extrapyramidal Rating Scale) scores,16 and the PANSS (Positive and Negative Syndrome Scale) scores.17 The SWN is a 20-item self-rating

scale, consisting of five subscales: Inhibitors,research,lifescience,medical emotional regulation, self-control, mental functioning, social integration, and physical functioning. It does not require patients’ SPTLC1 distinction between pharmacogenic and morbogenic components. Spatial and temporal parameters of gait were measured by using an ultrasonic system for gait analysis. The study revealed three major results: first, in conventionally treated patients, the SWN total score significantly correlated with stride length (R 2=0.39;P<0.01), whereas in atypically treated and drug-naïve patients it significantly correlated with the PANSS score (atypically treated: R 2=0.25,P<0.05; drug-naïve: R 2=0,64, P<0.01), mainly due to the correlations with the “negative symptoms” and the “general psychopathology” subscores. Second, correlations with stride length were significant, not, only in the “physical functioning” subscore of the SWN, but also in all other subscores. And third, correlations of the SWN scores with ESRS scores were weak.
