<unk>  (SSA) is a tendency to perceive normal somatic and visceral sensations as being relatively intense, disturbing and noxious. It is a common feature of hypochondriasis and is commonly found with fibromyalgia, major depressive disorder, some anxiety disorders, Asperger syndrome, and alexithymia. One common clinical measure of SSA is the<unk>  Scale (SSAS). The term<unk>  of bodily sensations” was coined by Dr. Arthur J. Barsky in 1979 to explain why patients suffering from the same medical disease experienced symptoms differently. He described it as “a temporally stable, generalised feature” of hypochondriasis. In the 1980s, the term<unk> ” (SSA) was first used. It is unclear whether persons with SSA have a truly increased physiological sensitivity to bodily sensations. One study paradoxically found lower levels of SSA in hypochondriacs who reported being constantly aware of their own heartbeats. Tentative electroencephalography results tend to indicate SSA is more likely due to differences in long-latency cognitive processing, rather than objective physiological differences in sensitivity. It is not currently known whether SSA causes or is caused by any of these conditions, only that they are comorbid conditions. One small study found that, in patients with depression, SSA may be part of the depression (i.e., treating the depression reduced the SSA).
