Background:
Patients with functional movement disorders (FMDs) are commonly seen by neurologists and psychosomatic medicine psychiatrists. Research literature provides scant information about the subjective experiences of individuals with this often chronic problem.
Objective:
To enhance our understanding of psychologic aspects of FMDs by conducting qualitative interviews of research subjects.
Methods:
In total, 36 patients with FMDs were recruited from the Human Motor Control clinic at the National Institutes of Health. Each subject participated in a qualitative psychiatric interview and a structured diagnostic psychiatric interview.
Results:
Of our 36 subjects, 28 had current or lifetime psychiatric disorders in addition to conversion disorder and 22 had current disorders. Qualitative interviews provided rich information on patients' understanding of their illnesses and impaired cognitive processing of emotions.
Conclusion:
Our study supports the addition of open-ended qualitative interviews to delineate emotional dynamics and conceptual frameworks among such patients. Exploratory interviews generate enhanced understanding of such complex patients, above and beyond that gained by assessing DSM diagnostic comorbidities.
