We reviewed the medical records of children who were diagnosed in our clinic with PMDs since 1988 and identified 54 patients with PMDs, representing 3.1% of our pediatric movement disorder population and 5.7% of all PMD cases. The mean age at symptom onset was 14.2 years (±2.11, range 7.6,17.7). Similar to published data in adults, two-thirds of children exhibited multiple PMD phenotypes, the most common being tremor followed by dystonia and myoclonus. Most PMDs were abrupt in onset, paroxysmal and triggered by identifiable physical or psychological trauma. As in adults, childhood PMDs were more likely to affect females, but there was no female predominance in children less than 13 years old. Although prior studies suggest that medically unexplained symptoms beginning in childhood often follow a benign course, this cohort of children experienced marked disability and morbidity related to PMDs, including prolonged school absences and unnecessary surgical procedures in more than one-fifth of patients. © 2008 Movement Disorder Society [source] Psychogenic movement disorders in children: A report of 15 cases and a review of the literature,,MOVEMENT DISORDERS, Issue 13 2008Petra Schwingenschuh MD Abstract Data on psychogenic movement disorders (PMD) in children are scarce, with most existing literature relating to adults only. We report 15 cases with the aim of highlighting the clinical characteristics, risk factors, comorbidity, treatment, outcome, and prognosis of PMD in children. Only 13% of cases had onset before age 10, with the mean age at onset being 12.3 years. Females were predominantly affected (F:M = 4:1). The most common types of movement disorders seen were dystonia (47%), tremor (40%), and gait disorders (13%). Multiple hyperkinetic phenomenologies were observed in many cases. Abrupt onset and precipitation by minor injuries, and stressful life events were commonly reported. Clinical clues on examination suggesting a psychogenic origin were similar to those identified in adults. A distinct feature of PMD in children was the predominant involvement of the dominant limb. The underlying psychiatric diagnosis was conversion disorder in the majority of cases. Time from symptom onset until diagnosis of a PMD varied broadly (between 2 weeks and 5 years). Treatment with cognitive and behavioral therapy and rehabilitation by a multidisciplinary team led to improvement in most cases. However, treatment was much more effective in children with a short time from symptom onset to diagnosis and treatment. © 2008 Movement Disorder Society [source] Transcultural comparison of psychogenic movement disordersMOVEMENT DISORDERS, Issue 10 2005Esther Cubo MD Abstract Prompted by the lack of cross-cultural comparative data, and because a better understanding in the different clinical presentations of psychogenic movement disorders (PMDs) is relevant to neurological assessment and interventions, we compared the phenomenology, anatomical distribution, and functional impairment of PMDs in the United States and Spain. Consecutive patients diagnosed with PMD by a movement disorder specialist from one US site and from eight Spanish university centers were included in the study. The two groups were similar in their movement types, anatomical distribution, and functional impairment. PMDs were more prevalent in women than in men and were most common in upper and lower extremities. Gait and speech dysfunctions were distributed similarly in both countries. We found action tremor to be the most frequent PMD in both countries. © 2005 Movement Disorder Society [source] | ||||||||||
