ABSTRACT
To explore the characteristics of exploratory eye movement (EEM) and hypothalamic-pituitary-adrenal axis (HPA) in elderly patients with acute bipolar and unipolar depression. Methods Thirty-eight elderly patients with bipolar depression (bipolar group) and thirty-nine patients with unipolar depression (unipolar group) were enrolled. The 24-item Hamilton depression rating scale (HAMD-24) was used to evaluate depressive symptoms. The levels of peripheral serum adrenocorticotropic hormone (ACTH) and cortisol (COR) were detected. EEM was recorded to obtain the number of eye fixation (NEF), responsive search score (RSS) and discriminant analysis (D). Results Compared with the unipolar group, the bipolar group had earlier onset, longer duration, and more admissions (P＜0.05). In comparison with the bipolar group, the unipolar group had higher levels of ACTH and COR (P＜0.05), and higher abnormal proportion of COR and ACTH levels. D-values were higher and RSS-values were lower in unipolar group than in bipolar group. There were no significant differences in NEF and HAMD total scores and its subfactors between the two groups (P＞0.05). Correlation analysis showed that the D value of unipolar group was positively correlated with COR level (r=0.482, P=0.002) but not with other indexes (P＞0.05). There were no significant correlations between EEM parameters and serum levels of HPA hormones in bipolar group (P＞0.05). Conclusion There are different clinical features, EEM indicators, the serum levels of ACTH and COR between acute unipolar and bipolar depression, which suggests the heterogeneity between the two diseases.
ABSTRACT
Objective:To investigate the eye movement anormalities of Obsessive-Compulsive Disorder (OCD) and their possible clinical significances. Methods: Exploratory eye movement in 57 patients with OCD according to DSM-IV criteria (27 medicated, 30 un-medicated) and 50 normal controls matched with sex, age and education were examined respectively. Results: Compared with normal controls, patients with OCD demonstrated low scores in most of the indices of exploratory eye movement. The rates of positive discrimiant score in OCD and normal controls were 37%(21/57) and 8% (4/50), respectively (X2 = 12.27, P
ABSTRACT
Objective To observe the cognitive fuction difference between post-stroke depression(PSD) and non-post-stroke depression(NPSD) patients.To evaluate the clinical value of exploratory eye movement(EEM) and event-related potentials(ERP) on PSD.Methods EEM and ERP test were used for 50 PSD,50 NPSD patients and 48 normal controls.The results were compared.Results The abnormal rate of EEM and ERP test in PSD group were 96%(48/50) and 92%(46/50)respectively,and the abnormal rate of EEM and ERP test in NPSD group were 86%(43/50)and 82%(41/50)respectively.The number of eye fixation(NEF)and the responsive search score(RSS)of PSD and NPSD group were significant lower and the scores of discriminant(D) were significant higher than those in the normal control group(all P
