In somatoform disorders the individual complains of bodily symptoms that suggest a physical defect or dysfunction sometimes rather dramatic in nature but for which no physiological basis can be found. In dissociative disorders, the individual experiences disruptions of consciousness, memory, and identity. Somatoform disorders: soma means, body. in somatoform disorders, psychological problems take a physical form. The physical symptoms have no known physiological explanation and are not under voluntary control. They are thought to be liked to psychological factors, presumably anxiety, and are assumed to be psychologically caused: this category has been controversial ever since the release of dsm-iv. Indeed, a group of prominent researchers presented the radical argument that somatoform disorders should be removed from the pending dsm-5. The terminology is often unacceptable to patients. The distinction between disease-based symptoms versus those that are psychogenic may be more apparent than real.
