Conversion disorder (CD), also called functional neurologic symptom disorder, is a psychiatric disorder with prominent motor Motor Neurons which send impulses peripherally to activate muscles or secretory cells. Nervous System: Histology or sensory Sensory Neurons which conduct nerve impulses to the central nervous system. Nervous System: Histology impairment which is not compatible with any known neurologic medical condition. The deficits are not consciously produced.

Conversion disorder presents with neurologic symptoms that are inconsistent with structural disease.
The following 2 tests may help differentiate conversion disorder from organic disease, if the respective neurological deficits are present.
|Symptom||Physical exam maneuver||Characteristic findings for conversion disorder|
|Tremor Tremor Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease. Intention or action tremor, a common manifestation of cerebellar diseases, is aggravated by movement. In contrast, resting tremor is maximal when there is no attempt at voluntary movement, and occurs as a relatively frequent manifestation of parkinson disease. Myotonic Dystrophies||Distraction||Tremor Tremor Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease.

|Impaired gait Gait Manner or style of walking. Neurological Examination||Chair test||Gait Gait Manner or style of walking. Neurological Examination is impaired but patient is able to rock chair back and forth while sitting down.|
|Anesthesia Anesthesia A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures. Anesthesiology: History and Basic Concepts||Dermatome Dermatome Spinal Disk Herniation testing||Testing of loss of sensation does not follow dermatome Dermatome Spinal Disk Herniation patterns.|
|Blindness Blindness The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of eye diseases; optic nerve diseases; optic chiasm diseases; or brain diseases affecting the visual pathways or occipital lobe. Retinopathy of Prematurity||Fingertip touching test||
|Deafness||Startle test||Patient becomes startled in response to unexpected noise.|
|Symptoms||Excessive worry||Exam findings|
|Somatic symptom disorder Somatic symptom disorder Somatic symptom disorder (SSD) is a condition characterized by the presence of 1 or more physical symptoms associated with excessive thoughts and feelings about symptom severity. Symptoms are usually not dangerous, but the patient devotes excessive time and energy to figuring out their underlying cause and how to treat them. Somatic Symptom Disorder||+||+||–|
