Are Patients with Psychogenic Movement Disorders More Likely to be Healthcare Workers?

ABSTRACT: Background:Reported risk factors for the development of a psychogenic movement disorder (PMD) include young age, female gender, history of abuse, current or past psychiatric disorder, lower levels of education and socioeconomic status, and employment as a healthcare worker. Although employment in healthcare is included in several diagnostic criteria for PMD, as well as in many case series, this association has never been validated. Methods:Using the University of Maryland Movement Disorder Database (UMMDD), we identified PMD cases, as well as patients with isolated focal dystonia as controls. An experienced movement disorder specialist diagnosed all patients, and all cases met criteria for clinically established PMD. Demographic and occupational histories were obtained from medical records and were supplemented by telephone interviews. PMD cases and controls were compared using t tests/?2 tests. Results:Controls (n = 148) were older than PMD cases (n = 132), with an average age of 61.4 and 52.1 years, respectively (P < 0.001); there were no significant differences between groups with respect to gender, education level, and ethnicity. The proportion of healthcare workers was not significantly different between PMD cases and controls (25% of PMD cases vs. 20% of controls; P = 0.28). Conclusions:In contrast to traditional teaching, this investigation demonstrates that in our patient population, patients with a PMD were no more likely to be employed as healthcare workers than patients with isolated focal dystonia. This study calls into question the use of employment in healthcare as a reliable criterion to support the diagnosis of PMD.

Diagnostic agreement in patients with psychogenic movement disorders.

Project description:The reliability and applicability of published diagnostic criteria for psychogenic movement disorders (PMDs) have never been examined.Eight movement disorder and six general neurologists rated 14 patients diagnosed with PMD and 14 patients diagnosed with organic movement disorders. Raters provided a dichotomous judgment (i.e., psychogenic or organic) upon review of video-based movement phenomenology and a category of diagnostic certainty based on the Fahn-Williams and Shill-Gerber criteria after accessing standardized clinical information. We measured interobserver agreement on the diagnosis and clinical certainty judgment of PMD.In both groups of raters, agreements were "fair" on the video-based dichotomous judgment, but improved to "substantial" after access to standardized clinical information. "Slight" to "poor" agreement was reached for the "probable" and "possible" categories of diagnostic certainty corresponding to both diagnostic criteria.Diagnosis according to clinical available criteria for PMD yields poor diagnostic agreement.

Treatment of functional (psychogenic) movement disorders.

Project description:Functional (psychogenic) movement disorders are a common source of disability and distress. Despite this, little systematic evidence is available to guide treatment decisions. This situation is likely to have been influenced by the "no man's land" that such patients occupy between neurologists and psychiatrists, often with neither side feeling a clear responsibility or ability to direct management. The aim of this narrative review is to provide an overview of the current state of the evidence regarding management of functional movement disorders. This reveals that there is some evidence to support the use of specific forms of cognitive behavioral therapy and physiotherapy. Such treatments may be facilitated in selected patients with the use of antidepressant medication, and may be more effective for those with severe symptoms when given as part of inpatient multidisciplinary rehabilitation. Other treatments, for example hypnosis and transcranial magnetic stimulation, are of interest, but further evidence is required regarding mechanism of effect and long-term benefit. Though prognosis is poor in general, improvement in symptoms is possible in patients with functional movement disorders, and there is a clear challenge to clinicians and therapists involved in their care to conduct and advocate for high-quality clinical trials.

Psychogenic Movement Disorders: Gait Is a Give-Away!

Project description:The aim of this article is to point out that an incongruity of gait disorder (either in relation to the presenting movement disorder or incongruity with any type of organic gait disorder) is a useful clue in diagnosing psychogenic movement disorders. To illustrate this, we present a case series of patients with various types of psychogenic movement disorders (rest tremor, myoclonus, dystonia, and chorea). Incongruity of the walking pattern with the presenting movement disorder was a revealing diagnostic clue in all cases. "Incongruity" is currently a main plank in the diagnosis of psychogenic conditions. Our series emphasizes that incongruity of the gait pattern may be the most important sign in a patient where it is otherwise difficult to establish whether the movement disorder is congruous or incongruous with an organic disorder.

Psychogenic facial movement disorders: clinical features and associated conditions.

Project description:The facial phenotype of psychogenic movement disorders has not been fully characterized. Seven tertiary-referral movement disorders centers using a standardized data collection on a computerized database performed a retrospective chart review of psychogenic movement disorders involving the face. Patients with organic forms of facial dystonia or any medical or neurological disorder known to affect facial muscles were excluded. Sixty-one patients fulfilled the inclusion criteria for psychogenic facial movement disorders (91.8% females; age: 37.0 ± 11.3 years). Phasic or tonic muscular spasms resembling dystonia were documented in all patients most commonly involving the lips (60.7%), followed by eyelids (50.8%), perinasal region (16.4%), and forehead (9.8%). The most common pattern consisted of tonic, sustained, lateral, and/or downward protrusion of one side of the lower lip with ipsilateral jaw deviation (84.3%). Ipsi- or contralateral blepharospasm and excessive platysma contraction occurred in isolation or combined with fixed lip dystonia (60.7%). Spasms were reported as painful in 24.6% of cases. Symptom onset was abrupt in most cases (80.3%), with at least 1 precipitating psychological stress or trauma identified in 57.4%. Associated body regions involved included upper limbs (29.5%), neck (16.4%), lower limbs (16.4%), and trunk (4.9%). There were fluctuations in severity and spontaneous exacerbations and remissions (60%). Prevalent comorbidities included depression (38.0%) and tension headache (26.4%). Fixed jaw and/or lip deviation is a characteristic pattern of psychogenic facial movement disorders, occurring in isolation or in combination with other psychogenic movement disorders or other psychogenic features.

Psychogenic Movement Disorders in Adults and Children: A Clinical and Video Profile of 58 Indian Patients.

Project description:BackgroundPsychogenic movement disorders (PMDs) represent 2% to 20% of patients with movement disorders. There is a paucity of literature on PMD in children, with most existing literature relating to adults only.MethodsFor this detailed report of 58 patients (33 adults and 25 children) with PMD, history was assessed in the form of disease onset, duration, precipitating factors, diagnosis, and outcome. Movement phenotype was classified in terms of its appearance as tremor, dystonia, myoclonus, chorea, and others. Clinical evaluations were done to document variability, distractibility, and entrainment. Surface electromyography studies were obtained in patients with tremor.ResultsSeven adults and 7 children were classified with "documented" PMD, and 26 adults and 18 children were classified with "clinically established" PMD. Abrupt onset was common in adults (75.75%) and children (68%). The most common precipitating factors were family and social issues (42.42%) in adults and fear of examination (40%) and school-related issues (24%) in children. Tremor was the most common PMD in both adults and children. The second most common PMD was hemifacial spasm in adults.ConclusionThe majority of patients had abrupt onset of symptoms, and tremor was the most common form of movement disorder. The second most common PMDs were hemifacial spasm in adults and dystonia and gait abnormality in children. The most common precipitating factors in adults were related to family and social issues; whereas, in children, examination and school-related issues were most common. Complete improvement was seen in only 405 of patients.

Diagnostic performance of the "Huffing and Puffing" sign in psychogenic (functional) movement disorders.

Project description:ObjectiveTo determine the diagnostic value of effort-associated behaviors ("huffing and puffing" spectrum) in patients with psychogenic movement disorders.MethodsThree blinded clinicians rated presence, severity, and duration of effort-associated features during standing and walking tasks on edited videos of 131 patients with psychogenic gait disorders and 37 patients with organic gait disorders.ResultsHuffing, grunting, grimacing, and breath holding were the most common effort-associated behaviors in patients with psychogenic gait disorders, with a combined prevalence of 44% and disproportionate to the severity of gait impairment compared to organic gait disorders. The presence of "huffing and puffing"-type behaviors yielded a relatively low sensitivity but high specificity for the diagnosis of psychogenic movement disorders, increasing the odds of diagnosis 13-fold (95%, CI: 4.2-43.8) compared to organic gait disorders.ConclusionsDemonstration of effort-associated behaviors during standing and walking strongly supports the psychogenic nature of disorders when gait is involved.

Paroxysmal non-kinesigenic dyskinesia, post-streptococcal syndromes and psychogenic movement disorders: a diagnostic challenge.

Project description:We report a case of a 15-year-old boy presenting with sudden attacks of hyperkinetic movements of the limbs, trunk and neck. Clinical features were suggestive of paroxysmal non-kinesigenic dyskinesia, but the elevated antistreptolysin O antibody titre and history of recurrent upper airways infection led us to consider a post-streptococcal syndrome as a possible diagnosis. The patient started therapy with benzathine penicillin, sodium valproate and clonazepam without any significant improvement. A successive psychiatric assessment revealed the presence of a psychogenic movement disorder. Psychodynamic psychotherapy and individual counselling were started with progressive improvement of psychological symptoms and gradual resolution of hyperkinetic episodes, without any recurrence recorded during the follow-up (10 months).

Healthcare Workers Who Work With COVID-19 Patients Are More Physically Exhausted and Have More Sleep Problems.

Project description:In this survey study of 7,208 Dutch healthcare workers, we investigate whether healthcare workers dealing with COVID-19 patients experience lower general health, more physical and mental exhaustion and more sleep problems than other healthcare workers. Additionally, we study whether there are differences in well-being within the group of healthcare workers working with COVID-19 patients, based on personal and work characteristics. We find healthcare workers who are in direct contact with COVID-19 patients report more sleep problems and are more physically exhausted than those who are not in direct contact with COVID-19 patients. Mental exhaustion and general health do not significantly differ between healthcare workers who are in direct contact with COVID-19 patients and those who are not. Among healthcare workers in direct contact with COVID-19 patients, lower well-being on one or more indicators is reported by those who are female, living alone, without leadership role, or without sufficient protective equipment. Regarding age, physical exhaustion is more prevalent under healthcare workers older than 55 years, whereas mental exhaustion is more prevalent under healthcare workers younger than 36 years. These results stress the need of mental and physical support of healthcare workers during a pandemic, catered to the needs of healthcare workers themselves.

Historical and More Common Nongenetic Movement Disorders From Asia.

Project description:Nongenetic movement disorders are common throughout the world. The movement disorders encountered may vary depending on the prevalence of certain disorders across various geographical regions. In this paper, we review historical and more common nongenetic movement disorders in Asia. The underlying causes of these movement disorders are diverse and include, among others, nutritional deficiencies, toxic and metabolic causes, and cultural Latah syndrome, contributed by geographical, economic, and cultural differences across Asia. The industrial revolution in Japan and Korea has led to diseases related to environmental toxin poisoning, such as Minamata disease and β-fluoroethyl acetate-associated cerebellar degeneration, respectively, while religious dietary restriction in the Indian subcontinent has led to infantile tremor syndrome related to vitamin B12 deficiency. In this review, we identify the salient features and key contributing factors in the development of these disorders.

Personality traits in psychogenic nonepileptic seizures (PNES) and psychogenic movement disorder (PMD): Neuroticism and perfectionism.

Project description:ObjectivePsychogenic movement disorder (PMD) and psychogenic nonepileptic seizures (PNES) are two subtypes of conversion disorder (CD). In this case-control study, we asked whether these subtypes varied as a function of personality and history of childhood abuse.MethodsFifty-nine patients with PMD from the Human Motor Control Section Clinic at the National Institutes of Health, 43 patients with PNES from the Rhode Island Hospital Neuropsychiatry and Behavioral Neurology Division, and 26 healthy volunteers (HC) received a battery of neurological, psychiatric and psychological assessments, including the NEO Personality Inventory Revised (NEO PI-R), the Childhood Trauma Questionnaire (CTQ), and the Traumatic Life Events Questionnaire (TLEQ).ResultsOne-way ANOVA between the three groups indicated significant differences in overall domains of Neuroticism (p=0.001) and Conscientiousness (p=0.009): Patients with PNES reported significantly greater levels of Neuroticism (p=0.002) and lower levels of Conscientiousness (p=0.023) than patients with PMD. Levels of Neuroticism remained significantly higher in both PMD and PNES than HC following correction for multiple comparisons. Patients with PNES reported greater levels of depressive and anxiety symptoms, overall psychopathology, greater history of sexual abuse, greater levels of alexithymia, higher levels of dissociative symptoms, and an earlier age at which they experienced their most distressing traumatic event than patients with PMD.ConclusionsThese findings suggest that personality traits, type of abuse and age of onset of trauma varies as a function of CD subtype. Patients with PNES rated greater Neuroticism and lower Conscientiousness than patients with PMD. These differing psychological profiles may inform differing treatment approaches such as psychological therapies for PNES and physiotherapy (with/without psychotherapy) for PMD.
