Psychogenic disease
Classified as a "conversion disorder" by the DSM-IV, a psychogenic disease is a condition in which mental stressors cause physical symptoms matching other disorders. The manifestation of physical symptoms without biologically identifiable cause results from disruptions in normal brain function due to psychological stress. During a psychogenic episode, neuroimaging has shown that neural circuits affecting functions such as emotion, executive functioning, perception, movement, and volition are inhibited. These disruptions become strong enough to prevent the brain from voluntarily allowing certain actions (e.g. moving a limb). When the brain is unable to signal to the body to perform an action voluntarily, physical symptoms of a disorder arise.
The term psychogenic disease is often used similarly to
Diagnosis
With the advent of medical screening technologies such as electroencephalography (EEG) monitoring, psychogenic diseases are being diagnosed more frequently, as medical professionals have increasingly precise tools to evaluate patients.[2] When a patient does not display typical markers of a disorder that would normally show up from medical exams, physicians may diagnose a patient's symptoms as being psychogenic. Research into understanding psychogenic disorders has led to the development of electronic diagnostic tests for ruling out the usual biological markers of a disorder, as well as new clinical observation procedures. A test a physician may employ for identifying a psychogenic disorder would be to see if the symptom changes with suggestion, for example a patient may be told to use a tuning fork to aid symptoms in a movement disorder.[3]
Despite the understanding of psychogenic symptoms, it is not assumed that all medically unexplained illness must have a psychological cause. It remains possible that
