Saw this elsewhere & thought this abstract of importance to those of us who suffer from sensory overload. There is so little literature on this symptom & it is my worst problem. If interested, read to the last sentence. I hope this full article is posted to the library here. Psychosomatics 49:235-242, May 2008 Comorbid Somatic Symptoms and Functional Status in Patients With Fibromyalgia and Chronic Fatigue Syndrome: Sensory Amplification as a Common Mechanism Michael E. Geisser, Ph.D., Cathy Strader Donnell, Ph.D., Frank Petzke, M.D., Richard H. Gracely, Ph.D., Daniel J. Clauw, M.D., and David A. Williams, Ph.D. BACKGROUND: Somatic symptoms are common in conditions such as fibromyalgia (FM) and chronic fatigue syndrome (CFS). OBJECTIVE: Authors investigated a potential shared pathologic mechanism: a generalized perceptual abnormality where there is heightened responsiveness to varied sensory stimulation, including pain. METHOD: A composite measure of sensory sensitivity was created and compared with measures of somatic symptoms, comorbid psychological disturbances, and self-reported physical functioning in 38 patients with FM and/or CFS. RESULTS: Sensory amplification influenced physical functioning indirectly through pain intensity, and physical symptoms and fatigue also independently contributed to physical functioning. CONCLUSION: Sensory amplification may be an underlying pathophysiologic mechanism in these disorders that is relatively independent of depression and depressive symptoms.
