For many individuals, substance abuse possesses characteristics of chronic disorders in that individuals experience repeated cycles of cessation and relapse; hence viewing drug dependence as a chronic, relapsing disorder is increasingly accepted. The development of a treatment for a chronic disorder requires consideration of the ordering of treatments, the timing of changes in treatment, and th...

The purpose of this prospective study was to investigate the effect of the patterning of workplace bullying and harassment over two time points (chronic, remission, onset, and never) on psychological and physical stress reactions. The subjects were 543 workers at welfare facilities for the elderly in Japan who completed a self-administered questionnaire at Time 1 (from August to September, 2009...

Background: Multiple sclerosis (MS) is a progressive chronic neurologic disorder which topically causes the destruction and inflammation of the myelin sheath in the brain and the spinal cord. It also affects the patient's emotions and can be treated using complementary medicine. Objectives: The present study was conducted to investigate the effectiveness of yoga therapy in reducing anxiety, st...

early life events influence life-long patterns of emotionality and stress responsiveness and alter the rate of brain and body aging.  much research attention has focused on the programming effects of the hypothalamus pituitary axis (hpa) in early life and on understanding hpa function in response to stressors in adulthood. in comparison, there has been relatively little research on adolescence,...

Endometriosis is a model of a benign gynecologic disease associated with two major symptoms: pain and infertility. When becomes chronic, severe psychological and neuroendocrine changes may occur. The high levels of perceived stress caused by symptoms cause a neuroendocrine disequilibrium thus contributing to the progression of the disease. Elevated stress levels alter hormonal secretions, mood ...

Oxidative stress has been implicated in the pathophysiology of multiple human diseases, in addition to the aging process. Although various stimuli exist, acute exercise is known to induce a transient increase in reactive oxygen and nitrogen species (RONS), evident by several reports of increased oxidative damage following acute bouts of aerobic and anaerobic exercise. Although the results are s...

it has been shown that stress and chronic pain could prevent the development of tolerance to morphine analgesia, which appears to be related to the activation of hypothalamus–pitutitary–adrenal (hpa) axis, activation of neuroendocrine systems and changes in neurochemical levels. moreover, the involvement of nitric oxide (no) in the development of tolerance to morphine analgesia has been implica...
