The goal of my study is to test the overarching hypothesis that art therapy is effective because it targets emotional dysregulation that often accompanies significant health stressors. By reducing the salience of illness-related stressors, art therapy may improve overall mood and recovery, particularly in patients with cancer. After consulting the primary literature and review papers to develop psychological and neural mechanisms at work in art therapy, I created a hypothetical experimental procedure to test these hypotheses to explain why art therapy is helpful to patients with chronic illness. Studies found that art therapy stimulates activity of multiple brain regions involved in memory retrieval and the arousal of emotions. I hypothesize that patients with chronic illness have a reduced capacity for emotion regulation, or difficulty recognizing, expressing or altering illness-related emotions (Gross & Barrett, 2011). Further I hypothesize that art therapy improves mood and therapeutic outcomes by acting on the emotion-processing regions of the limbic system, and thereby facilitating the healthy expression of emotion, emotional processing, and reappraisal. More mechanistically, I propose art therapy reduces the perception or salience of stressors by reducing amygdala activity leading to decreased activation of the hypothalamic-pituitary-adrenal (HPA) axis. The art therapy literature and my hypothesis about its mechanisms of action became the basis of my proposed study. To assess the effectiveness of art therapy in alleviating symptoms of chronic disease, I am specifically targeting patients with cancer who exhibit a lack of emotional regulation. Saliva is collected 3 times a week on the day of intervention: morning after waking, afternoon, and evening. Stress levels are tested using one-hour art therapy sessions over the course of 3 months. The Perceived Stress Scale (PSS) assesses an individual's perceived stress and feelings in past and present situations, for the control and intervention group. To measure improvement in overall mood, 10 one-hour art sessions are performed on patients over 10 weeks. A one-hour discussion analyzing the participants' artwork follows each art session. The Spielberger State-Trait Anxiety Inventory (STAI) assesses overall mood for the intervention and control groups. I created rationale and predictions based on the intended results of each experiment.

A Research Review of The Neurological Complications of Ankylosing Spondylitis

Description

Neurological manifestations may be more prominent and have a larger role in ankylosing spondylitis than previously thought. Ankylosing Spondylitis is a rheumatic disease primarily identified by its autoinflammatory characteristics and is highly associated with the HLA-B27 gene.

Neurological manifestations may be more prominent and have a larger role in ankylosing spondylitis than previously thought. Ankylosing Spondylitis is a rheumatic disease primarily identified by its autoinflammatory characteristics and is highly associated with the HLA-B27 gene. While it’s cause is not yet fully understood and it’s symptoms widely vary, neurological impairment is not uncommon. The neurological manifestations of Ankylosing Spondylitis include but are not limited to pain sensitization, altered brain phenotype, and disrupted cardiac conduction. Central and peripheral nervous system involvement may be more significant than previously thought and have the potential to cause demyelinating diseases, spinal cord, and nerve root injuries. Altered connectivity throughout various regions within the brain further exemplify the need for a better understanding of the disease and better treatment development. Higher instances of depression and dementia were also reported and coincide with not only a less active lifestyle, but altered brain activity. Studies on cardiac conduction and arrhythmias in AS patients revealed parasympathetic and sympathetic nervous system dysregulation. These studies have explored the possibility of new targets for treatment involving cardiac mechanisms. Treatments for diseases of a similar suspected pathology, new prospective targets for therapy, and a more thorough understanding of current treatments for the disease may be the key in providing more substantial relief. By further investigation in the role of the nervous system in Ankylosing Spondylitis, the disease may become more manageable for patients and greatly increase quality of life in the future.
