Abstract
Background: Memory is one of the main functions that is impaired by neurological disorders. Noticing the susceptibility of memory to emotions, the effect of emotional states on memory in patients with alzheimer, brain tumor, and normal individuals was investigated in this study. Materials and Methods: Through Causal-Comparative study, 26 patients with alzheimer, 38 patients with brain tumor, and 30 normal individuals were selected and tested by a memory-related computerized task on explicit recall memory and implicit memory. Results: Patients with alzheimer showed a poor performance in memory tasks. They recognized more sad and threatening words in their explicit memory. Overall, patients with alzheimer and tumor in comparison with normal individuals indicated poorer explicit/implicit memory functions, respectively. Conclusion: Cognitive processes of patients with alzheimer are influenced when they encounter simple emotional stimulus.

Abstract
Background: The theory of mind acts as an umbrella which covers the perception of children of others’ mental conditions under its banner and paves the way for child’s social cognition. This study was designed to compare the effects of different variables such as intelligence quotient (IQ), sex, age, and mental maintenance on the theory of mind development levels in autistic and normal children. Materials and Methods: In this case-control study, 19 autistic and 19 normal children were selected based on the in-reach sampling procedure and were also matched by age. The participants completed Wechksler intelligence scale for children, Stimman theory of mind task, and mental maintenance task. Results: In comparison to normal children, autistic children showed a clear deficiency in their theory of mind development levels however, age did not have a significant effect in this regard. Conversely, IQ and sex had significant impacts on the development of theory of mind. In addition, mental maintenance, alone, had a significant effect on the theory of mind. Conclusion: Noticing the existence of some primary levels of theory of mind in autistic children, some aspects of theory of mind can be compensated for through the provision of basic instructions and guidelines for development of intellectual and cognitive abilities in early childhood and primary stages of diagnosis.

Abstract
Background: Cardiovascular diseases are directly influenced by some specific psychological behaviors accompanied by stress and anxiety that in the long run increase cardiovascular diseases risk and bring about some complications. This study was carried out to examine the effects of relaxation and distraction training on anxiety reduction in cardiac patients,.
Materials and Methods: In this experimental study, sixty 40-65 year old patients with cardiac diseases were selected by convenience random sampling procedure and were randomly assigned to different experimental groups: 15 patients received relaxation training, 15 patients received distraction training, 15 patients received both relaxation and distraction training, and 15 patients stayed in the waiting list group. All participants completed STAI-S and STAI-T before and after the training program. Data were analyzed by factorial analysis of variance with repeated measures.
Results: The results indicated that instruction of anxiety reduction techniques significantly decrease cardiac patients’ anxiety. There were no significant differences between the two genders. Also, there were no significant decreases between different educational levels and types of diagnosis in the anxiety reduction.
Conclusion: Noticing the decrease in anxiety due to relaxation and distraction in patients hospitalized with cardiac diseases, the use of these techniques in all stages of prevention and treatment of coronary heart diseases seems necessary.

Abstract
Abstract
Background: The activation of inflammatory cascades reactions has been consistently demonstrated in the pathophysiology of Alzheimer’s disease (AD). Among several neuroinflammatory mechanisms, the tumor necrosis factor (TNF) signaling system has a central role in this process. The abnormal production of inflammatory factors may accompany the progression from mild cognitive impairment (MCI) to dementia. We aimed to examine serum levels of soluble TNF receptor (sTNFR1) in patients with MCI and AD as compared to cognitively unimpaired elderly subjects. We further aimed to investigate whether abnormal levels of these cytokines predict the progression from MCI to AD upon follow up.
Materials and Methods: We utilized cross-sectional determination of serum levels of sTNFR1 (ELISA method) in a test group comprising 150 older adults (30 AD, 60 MCI, and 60 healthy controls), and longitudinal reassessment of clinical status after12 months.
Results: At baseline, there were statistically significant differences in serum sTNFR1 between patients with MCI and AD and controls (p< 0.05). Also, patients with MCI who had more disorder in diagnostic functions and progressed to AD after one year, had significantly higher serum sTNFR1 levels as opposed to patients who retained the diagnosis of MCI upon follow up (p=0.03).
Conclusion: The results showed that abnormal activation of TNF signaling system, represented by increased expression of sTNFR1, is associated with a higher risk of progression from MCI to AD.
