RESUMEN
Objective:To explore the characteristics of cognitive function in patients with early onset and adult onset schizophrenia.Methods:In this cross-sectional study, 546 patients with schizophrenia who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-Ⅳ) were selected.Among them, 62 cases were defined as early onset schizophrenia (EOS, age of onset＜18 years) and 175 patients were defined as adult onset schizophrenia (AOS, age of onset≥25 years).Patients underwent clinical assessments with the Positive and Negative Symptom Scale (PANSS) and the Personal and Social Performance Scale (PSP), and comprehensive neuropsychological assessments.Results:The EOS patients got lower scores in motor function-PEGDOM T score [ (26±12) vs. (30±11), P＜0.01], working memory-average T score of PASAT and WMSSP[ (34±12) vs. (38±10), P＜0.05]and executive function (inhibition) -Stroop T score [ (35±12) vs. (39±10), P＜0.05]than AOS patients.No differences were fund in processing speed, verbal memory and learning, visual memory and learning (Ps＞0.05) between the two groups.Conclusion:It suggests that the EOS patients have worse motor function, working memory and inhibition.
RESUMEN
Objective:To compare the concordance between subjective experience and clinician-rated in different treatment phrase of elderly patients with depressive disorder,and to explore the relevant factors.Methods:Sixty-nine consecutive elderly patiems with depressive disorder diagnosed with International Classification of Diseases-10 criteria were included.The Visual Scale for Depression(VSD) were used to evaluate subjective experience of depression,while the Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),Minimum Mental State Examination (MMSE) were used by clinician to evaluate depression symptom,anxiety symptom and cognition at baseline,2-,4-and 52-week of the treatment respectively.Results:Compared with baseline,VSD scores were increased at 2 weeks and 4 weeks [(2.7 ± 1.6),(5.3 ± 2.0) vs.(7.0 ± 1.8),P ＜ 0.001],HAMD scores were decreased at 2 weeks and 4 weeks [(36 ± 11),(17 ±9) vs.(9 ±8),P ＜0.001],HAMA scores were decreased at 2 weeks and 4 weeks [(27 ± 10),(14 ±8) vs.(7 ±6),P ＜0.001].No significant differences were found between 4 weeks and 52 weeks.There was no correlation between VSD and HAMD scores at baseline and 2 weeks.There were significant correlations among scores of VSD and HAMD(r =-0.31,-0.74,Ps ＜ 0.05),HAMA (r =-0.36,-0.76,Ps ＜ 0.05) at 4 weeks and 52 weeks.Using logistic regression analysis,the concordance between VSD and HAMD related with the factors of HAMD,higher scores of anxiety/somatization factor were associated with lower concordance (OR =0.87),and higher scores of weight factor (OR =1.86),diurnal variation factor (OR =2.00),hopelessness factor (OR =1.13) were associated with higher concordance.Conclusion:Compared with acute depression phase,concordance between subjective experience and clinician-rated for depression may be higher at depression remission phase in elderly patients with depression,which suggests that characteristics of depression symptom may have a certain impact on the self-awareness for depression experience.
