| Summary: | <div id="ojsAbstract"><p><strong>Background:</strong> The pathophysiology of psychogenic movement disorders, including psychogenic tremor (PT), is only emerging.</p> <p><strong>Case Report:</strong> This is a single case report of a patient who met diagnostic criteria for PT. He underwent positron emission tomography (PET) of brain with 18F-deoxyglucose at resting state. His PET study showed symmetrically increased 18F-deoxyglucose uptake in both posterior medial parietal lobes. There was no corresponding abnormality on structural imaging.</p> <p><strong>Discussion:</strong> Hypermetabolism of the medial aspects of posterior parietal lobes bilaterally may reflect abnormal activity of sensory integration that is important in the pathogenesis of PT. This further supports the idea that non-organic movement disorders may be associated with detectable functional brain abnormalities.</p></div> |
