What is a common symptom of conversion disorder?

In conversion disorder, also known as functional neurological symptom disorder, individuals experience neurological symptoms that cannot be explained by medical or neurological conditions. Common symptoms include blindness, paralysis, abnormal gait, or other forms of motor or sensory dysfunction. These symptoms are real and can be quite debilitating, but they occur without any identifiable physical cause. The presence of such symptoms is central to conversion disorder, as they reflect a psychological conflict or stressor that manifests physically.

The other options reflect different psychological or physical issues. Insomnia is typically associated with anxiety, depression, or various medical conditions, rather than a conversion disorder. Social anxiety is characterized by a fear of social situations, leading to avoidance behaviors, while obsessive thoughts are indicative of obsessive-compulsive disorder or related anxiety disorders. Neither of these other symptoms aligns with the primary presentation of conversion disorder, which is characterized specifically by the impaired neurological function that manifests through physical symptoms like blindness or paralysis.
