Psychogenic movement disorders (PMD) are movement disorders that cannot be attributed to any known structural or neurochemical diseases, but represent the manifestation of an underlying psychiatric illness or malingering. Most cases of PMD fall in the psychiatric diagnostic category of conversion disorders of the motor subtype.
Features include very common findings: Movement abnormalities (abnormality of movement); and common findings: Difficulty walking (gait disturbance) and Abnormal speech pattern.
