PSYCHOSOMATIC MEDICINE

1. Dr. YASER ALHUTHAIL Associate Professor & Consultant Consultation Liaison Psychiatry PSYCHOSOMATIC MEDICINE

2. Psychosomatic medicine is an area of scientific investigation concerned with therelationbetween psychological factors and physiological phenomena in general and disease pathogenesis in particular. Unity of mind and body Integrates mind and body into a psychobiological unit; as dynamic interacting systems. A holistic approach to medicine.

3. Implications: Unity of mind and body: Psychological factors must be taken into account when considering all disease states Emphasis on examining and treating the whole patient, not just his or her disease or disorder.

4. Biomedical Model: The application of biological science to maintain health and treating disease. Engel (1977) proposed a major change in our fundamental model of health care. The new model continues the emphasis on biological knowledge, but also encompasses the utilization of psychosocial knowledge. “Biopsychosocial Model”

5. Stress can be described as a circumstance that disturbs, or is likely to disturb, the normal physiological or psychological functioning of a person. The body reacts to stress in this sense defined as anything (real, symbolic, or imagined) that by threatens an individual's survival by putting into motion a set of responses that seeks to diminish the impact of the stressor and restore homeostasis. Stress Theory

6. A psychosomatic framework. Two major facets of stress response. “Fight or Flight” response is mediated by hypothalamus, the sympathetic nervous system, and the adrenal medulla. If chronic, this response can have serious health consequences. The hypothalamus, pituitary gland, the adrenal cortex mediate the second facet. THE STRESS MODEL

7. Stressors activate noradrenergic systems in the brain and cause release of catecholamines from the autonomic nervous system. Stressors also activate serotonergic systems in the brain, as evidenced by increased serotonin turnover. Stress also increases dopaminergicneurotransmission in mesoprefrontal pathways. Neurotransmitter Responses to Stress

8. CRF is secreted from the hypothalamus. CRF acts at the anterior pituitary to trigger release of ACTH. ACTH acts at the adrenal cortex to stimulate the synthesis and release of glucocorticoids. Promote energy use, increase cardiovascular activity, and inhibit functions such as growth, reproduction, and immunity. Endocrine Responses to Stress

9. Inhibitionof immune functioning by glucocorticoids. Stress can also cause immune activation through a variety of pathways including the release of humoral immune factors (cytokines) such as interleukin-1 (IL-1) and IL-6. These cytokines can themselves cause further release of CRF, which in theory serves to increase glucocorticoid effects and thereby self-limit the immune activation. Immune Response to Stress

10. High level of Cortisol results in suppression of immunity which can cause susceptibility to infections and possibly also in many types of cancer. Changes in the immune system in response to stress are now very well established.

11. Immune suppression in response to stress occurs even after removal of the adrenal gland !!. There appears to be an alternative path, other than through the adrenals, for the brain to influence the immune response. Psychoneuroimmunology

12. A. A general medical condition (coded on Axis III) is present. B. Psychological factors adversely affect the general medical condition in one of the following ways: (1) the factors have influenced the course of the general medical condition as shown by a close temporal association between the psychological factors and the development or exacerbation of, or delayed recovery from, the general medical condition. (2) the factors interfere with the treatment of the general medical condition. (3) the factors constitute additional health risks for the individual. (4) stress-related physiological responses precipitate or exacerbate symptoms of a general medical condition. DSM-IV Diagnostic Criteria for Psychological Factors Affecting Medical Condition

13. Mental disorder affecting medical condition (e.g., an Axis I disorder such as major depressive disorder delaying recovery from a myocardial infarction) Psychological symptoms affecting medical condition (e.g., anxiety exacerbating asthma) Personality traits or coping style affecting medical condition (e.g., pathological denial of the need for surgery in a patient with cancer, hostile, pressured behavior contributing to cardiovascular disease) Maladaptive health behaviors affecting medical condition (e.g., lack of exercise, overeating) Stress-related physiological response affecting general medical condition (e.g., stress-related exacerbations of ulcer, hypertension, arrhythmia, or tension headache) Other unspecified psychological factors affecting medical condition (e.g., interpersonal, cultural, or religious factors)

14. Three enduring clinical features: - Somatic complaints that suggest major medical problems. - Psychological factors and conflicts that seem important. - Symptoms or magnified health concerns that are NOT under the patient’s conscious control. Somatoform Disorders

15. Somatization disorder Conversion disorder Pain disorder Hypochondriasis Body Dysmorphic Disorder Somatoform Disorders

16. The essential feature of somatization disorder is recurrent, multiple somaticcomplaints requiring medical attention but not associatedwith any physical disorder. Somatization disorder is the expression of personal and social distress in bodily complaints . Multiple symptoms of multiple systems for several years Chronic relapsing condition with no known cure. SOMATIZATION DISORDER

17. A disturbance of body functioning (usually neurological) that does notconform to current concepts of the anatomy and physiology of the central or the peripheral nervous system. It typically occurs in a setting of stress and produces considerable dysfunction. Involuntary movements, tics, seizures, abnormal gait, paralysis, weaknessetc. Conversion Disorder

18. Preoccupation with the fear of developing a serious disease or the belief that one has a serious disease. The fear is based on the patient's interpretationof physical signs or sensations as evidence of disease even though the physician's physical examination does notsupport the diagnosis of any physical disorder. However, the belief does nothave the certainty of delusional intensity. HYPOCHONDRIASIS

19. Preoccupation with pain is consuming and to some extent disabling. That is, pain becomes the predominant focusof the clinical presentation and the pain itself causes clinically significant distress or impairment and the patient's life becomes organized around the pain. Psychological factors are judged to play a role in this disorder. PAIN DISORDER

20. Preoccupation with an imagined defect in appearance. If a slight physical anomaly is present, the person's concern is markedly excessive. The preoccupation causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. BODY DYSMORPHIC DISORDER

21. Caring rather than curing Management is more realistic than treatment Therapeutic relationship Nature of symptoms in psychosomatic context Rule out depression and anxiety disorders Avoid investigations without indications Pharmacotherapy Copingskills Lifestyle changes MANAGEMENT

22. The subspecialty of psychiatry that incorporates clinical service, teaching, and research at the borderland of psychiatry and medicine. Liaison refers to interactions with nonpsychiatrist physicians for teaching psychosocial aspects of medical care. Consultation Liaison Psychiatry

23. Liaison psychiatrist may participate in ward rounds and team meetingswhile addressing the behavioral issues. Educationof nonpsychiatric physicians and health professionals about medical and psychiatric issues related to a patient’s illness. Liaison services lead to heightened sensitivityby medical staff, which result in earlier detectionand more cost-effectivemanagement of patients with psychiatric problems.
