background & aim: people with multiple sclerosis (ms) face numerous physical and psychological problems and use multiple strategies to manage these problems to reduce its impact on their own lives. the aim of this study is to explore the self-management strategies in people with ms . methods & materials: this study is a qualitative research with content analysis approach. data were collected th...

Multiple sclerosis (MS) is a chronic autoimmune disorder of central nervous system. This demyelinating disease affects more than 2.3 million people world wild. Most of patients are young adult. There are many possible triggering factors including infections, toxin, immunization, trauma, sunlight exposure and hormonal variable in pathogenesis of MS. One of the important trigger is stress. There ...

introduction: stress is defined as any environmental change that disturbs the maintenance of brain homeostasis. stress leads to production of pro-inflammatory cytokines that provoke neurodegenerative disorders. in the present study, we investigated the effects of dalteparin on hippocampal neuronal death induced by chronic stress in rats. methods: the study was carried out on 60 adult male wista...

results when the two ms groups were compared together, we found that cr was significantly increased (p value=0.008) and naa/cr was significantly decreased (p value=0.03) in non-enhancing lesions in ppms compared with rrms. there was no significant difference in naa, cho or naa/cho between the two ms subtypes. conclusion mrs is a potential way to differentiate ppms and rrms. objectives we compar...

Stress affects brain areas involved in learning and emotional responses, which may contribute in the development of cognitive deficits associated with major depression. These effects have been linked to glial cell activation, glutamate release and changes in neuronal plasticity and survival including atrophy of hippocampal apical dendrites, loss of synapses and neuronal death. Under neuro-infla...

BACKGROUND Little research has examined how chronic stress in different domains relates to allostatic load (AL). PURPOSE We examined the relationship between multiple chronic stressors with AL, and evaluated lifestyle factors as possible mediating factors. METHODS Three hundred one middle-aged Mexican-American women underwent a physical exam and completed measures of lifestyle factors and c...

INTRODUCTION Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tib...

It is suggested that acute stress shifts behavioral control from goal-directed, model-based toward habitual, model-free strategies. Recent findings indicate that interindividual differences in the cortisol stress response influence model-based decision-making. Although not yet investigated in humans, animal studies show that chronic stress also shifts decision-making toward more habitual behavi...
