Psychogenic seizures: video telemetry observations in 27 patients.
Psychogenic seizures are unusual during the first decade of life. To compare the clinical features of psychogenic seizures in young children with those of teenagers, the long-term electroencephalographic and video monitoring studies of all patients younger than 18 years of age with recorded episodes diagnosed as psychogenic seizures were reviewed from a single hospital during the past 7 years. The 27 patients were divided into 2 age groups: group A, 6-9 years (n = 5), and group B, 10-17 years (n = 22). All patients had habitual episodes recorded during monitoring. Although the adolescents displayed clinical patterns similar to adult patients with psychogenic seizures, the children demonstrated a clinical pattern characterized mainly by prolonged staring and unresponsiveness. The most common behaviors in the adolescent group were tremor (45%), intermittent stiffening (41%), and out-of-phase movements of the extremities (36%). Fifteen percent of the patients had a history of seizures. This study suggests that young children with psychogenic seizures have clinical profiles different from that of teenagers.
