ABSTRACT
Background and Objective: Anxiety disorder [AD] is one of the most common children disorders.In last two decades, several studies conducted to determine the mechanisms of child anxiety disorder specifically in base of neural mechanisms. However, studies about the electrophysiology of child anxiety disorder particularly in the quantitative electroencephalography [QEEG] are less than imaging studies. This study was performed to compare the quantitative EEG between children with anxiety disorder and normal subjects
Methods: This case- control study was done on 30 children with anxiety disorder and 30 normal healthy children with 6-7 years old. Electroencephalography was recorded for each subject. Power of 19 channel and 5 frequency bands delta, theta, alpha, beta and high beta [25-30 Hz] in the frontal, central and occipital area were recorded, respectively
Results: There was significant difference in delta absolute power in frontal lobe, theta and beta2 absolute power in central and high beta wave in occipital area between AD and normal children [P<0.05]. In other words, the delta absolute power in frontal lobe and theta and beta2 absolute power in central area of brain was less in AD children in compared to normals. Also, the high beta absolute power in occipital lobe was more in AD children in compared to normals
Conclusion: Recorded QEEG in relax time is a proper index of brain cortex metabolic activity. Therefore, low metabolic activity in particular parts of brain is determined by increasing slow waves power [delta and theta] or decreasing fast waves power [alpha and beta]
ABSTRACT
The present study investigated the effect of emotionally focused therapy [EFT] on factors contributing to emotional distress among infertile couples. In this semi-experimental study, the subjects consisted of 12 Iranian couples: six infertile men and six infertile women. They were assessed as depressed, anxious and stressful individuals using depression, anxiety and stress scale [DASS]. The subjects were randomly divided into control and experimental groups. The experimental group with six couples [i. e. three infertile men and three infertile women] received EFT, while the control group with similar number of couples [i. e. three infertile men and three infertile women] was deprived of the treatment. There were no significant differences between the two groups regarding job, educational level, income, age, marriage and infertility duration. The pre- and post-test comparisons of DASS subscales showed that level of depression, anxiety and stress among couples with EFT instruction was significantly less than those without such instructions [p<0.0001]. Emotionally focused therapy could reduce the rate of depression, anxiety and stress in infertile couples, regardless of the man or woman as the cause of infertility
