   Abstract 


Background: Patients present with “conversion disorder” as a response to any underlying stressful situation. It is clinically important to evaluate the presence, type, and temporal relation of the stressors, resulting in conversion. Further, knowing the sociodemographic and psychological profile of the conversion patient helps in better management. Aim: The aim of the study was to study the clinical presentations, sociodemographic characteristics, and underlying stressors associated with conversion disorder. Materials and Methods: Fifty patients admitted to the Department of Psychiatry, NRI Medical College and Hospital, Guntur, Andhra Pradesh, from January 2013 to December 2014, who fulfilled the inclusion criteria of the study were evaluated for sociodemographic characteristics, clinical presentations, and stressor on a semi-structured pro forma. Results: Majority of the patients with conversion symptoms were children and young adults (74.0%), females (62.0%), students (46.0%), married (54.0%), and those from nuclear families (78.0%) and rural background (62.0%). Socioeconomic status wise, majority (66.0%) of the patients belonged to middle class. Majority of the patients (92.0%) had a recognizable precipitating factor, of which family-related/marital (36.0%) and education/school-related (18.0%) problems accounted for the major types. Purely motor symptoms were the predominant presentation (84.0%) with unresponsiveness/syncopal attack and pseudo seizure being the commonest. Conclusion: Conversion disorders are commonly seen in females, children and young adults, students, and in those belonged to middle class in socioeconomic status and rural areas. They are mostly preceded by identifiable psychosocial stressors.

The term “conversion disorder” was coined by renowned psychologist Sigmund Freud, who hypothesized that the symptoms of conversion disorder reflect unconscious conflict.[1] The word conversion refers to the substitution of a somatic symptom for a repressed idea.[1],[2] Conversion disorder, renamed as functional neurological symptom disorder in Diagnostic and Statistical Manual of Mental Disorders (DSM)-V,[3] is defined as a deficit of sensory or motor function that cannot be explained by a medical condition and where psychological factors are judged to be associated with the deficit because symptoms are preceded by conflicts or other stressors.[4] It tends to start in early adulthood and generally follows a stress factor. In International Classification of Disease (ICD), 10th edition, conversion symptoms are classified as dissociative disorders (e.g., dissociative motor disorder), with similar diagnostic criteria.[5] Although conversion/dissociative disorders have been described in literature for long and being diagnosed for a goodtime, their etiology, pathogenesis, phenomenology, and management continue to evoke debate. The proper diagnosis of these patients has important implications for their clinical course.[6],[7]

Conversion disorder presents with loss of physical function with a wide range of signs and symptoms and findings on physical examination which are not consistent with any known neurological, anatomical, or physiological pathology.[8] Common examples of conversion symptoms include blindness, paralysis, dystonia, psychogenic nonepileptic seizures, anesthesia, swallowing difficulties, motor tics, difficulty walking, hallucinate ions, anesthesia, and dementia.[9] Despite lack of a definitive organic diagnosis, the patient's distress is quite real and the physical symptoms experienced by the patient can not be controlled at will.

Patients of conversion disorder spend nine times the cost for health care as people not having the disorder. It is also estimated that 82% of the adults with this disease stop working because of their symptoms.[10] The annual bill for conversion disorder in the United States is $20 billion, not counting absenteeism from work and disability payments due to the disease.[10] Despite its clinical importance, there has been only marginal progress in the understanding of conversion disorder relative to many other neurological and psychiatric disorders.[11]

The reported prevalence of conversion disorder varies widely depending on the population studied. Studies have estimated that 20%–25% of patients in a general hospital setting have individual symptoms of conversion, and 5% of patients in this setting meet the criteria for the full disorder.[12],[13] Further, medically unexplained neurological symptoms account for approximately 30% of the referred neurology outpatients.[14] In a study of 100 randomly selected patients from a psychiatry clinic, 24 were noted to have unexplained neurological symptoms.[14]

Among adults, women diagnosed with conversion disorder outnumber men by a 2:1–10:1 ratio; less educated people and those of lower socioeconomic status are more likely to develop conversion disorder; race by itself does not appear to be a factor.[10] There is a major difference between the populations of developing/underdeveloped countries compared to the developed countries; in developing countries, the prevalence of conversion disorder may run as high as 31%.[10]

Some Indian studies have focused on the clinical characteristics in conversion disorder.[15],[16] They have emphasized on the role of stressors in conversion disorder. In India, high occurrence of conversion disorder has been reported in young adults, from poor low income, joint families, and significantly higher in females.[17] Furthermore, higher prevalence of conversion disorder has been seen in illiterates, married housewives being the most common group.[18] However, less is known from the region of Southern India about the clinical presentations and sociodemographic variables in conversion disorder.

With this background, this study was planned and conducted with the aim to assess the various types of clinical presentations and the related sociodemographic variables in patients with conversion disorder in this part of Southern India.


   Materials and Methods Top


Study settings and design

A cross-sectional descriptive study of patients presenting with conversion symptoms was carried out from January 2013 to December 2014.

Patients attending the Department of Psychiatry of NRI Medical College and Hospital, Guntur, Andhra Pradesh (A.P) a tertiary care medical Institute in Southern India, with conversion/dissociative symptoms amounting to disorder were the study subjects. They were evaluated for possible precipitating factors, clinical features, sociodemographic profile using semi-structured pro forma.

Study tools

  • The ICD10 – Classification of mental and behavioral disorder: criteria for dissociative (conversion) disorder was used[4]
  • A semi-structured pro forma to record sociodemographic details which include age, sex, education, occupation, domicile, marital status, family type, and socioeconomic status; in addition to birth order, clinical presentations and possible precipitating factor for developing dissociative (conversion) disorder.


Inclusion criteria

Subjects of both sexes of age 6 years and above fulfilling the diagnostic criteria of dissociative (conversion) disorder according to ICD-10 and DSM-4 were included in the study.

Exclusion criteria

Subjects having known history of organic disorder including epilepsy and comorbid other psychiatric illness, for example, anxiety disorder and depressive disorder were excluded from the study.

Study procedure

All the study subjects were thoroughly evaluated based on history and mental status examination, and the diagnosis was confirmed by a senior psychiatrist.

Then, the written informed consent was taken from every patient before enrolling into the study. All the patients and their attendants were then evaluated to elicit necessary information required in our semi-structured pro forma.

Statistical analysis

Data were entered in excel spreadsheets. Categorical variables were presented as frequency and proportions, whereas continuous variables were presented as mean with standard deviations.

Ethical considerations

The study protocol was approved by the Institutional Ethics Committee of the institute. Written informed consent was taken from all the participants. In participants <18 years of age, consent was taken from parents or the primary caregiver and assent was taken from them.

The sociodemographic characteristics of the study subjects are summarized in [Table 1]. Majority of the subjects were female (62.0%), married (54.0%), and were in the age group of 18–30 years (38.0%), followed by 6–17 years of age group (36.0%). Half of the study subjects were students (46.0%), followed by housewives (44.0%). About half of the subjects were illiterates (44.0%) and another 32% were educated up to secondary level. Majority of the study participants had a rural background (62.0%) and belonged to a nuclear family (78.0%). Further, most of the study participants (66.0%) belonged to the middle class as per their socioeconomic status.

Purely motor symptoms were the most common type of clinical presentation (84.0%), followed by mixed ones (12.0%). Among the motor symptoms, syncopal attack/altered consciousness was the most common presentation (20.0%), followed by pseudoseizures (18.0%). Other motor symptoms included paresis (14.0%), hyperventilation (10.0%), aphonia/dysphonia (8.0%), abnormal gait/Astasia-Abasia (4.0%), and diplopia (4.0%). Only one patient (2.0%) presented with isolated sensory symptoms.

As many as 12.0% of the study subjects presented with “mixed symptoms,” which included Headache, burning sensation and weakness of the whole body [Table 2].

For evaluating whether the subjects had any obvious precipitating factor prior to onset of the disorder, they were divided into two groups: Children and young adults between age of 6 and 22 years and adults above the age of 22 years.

In the first group, out of the 23 subjects, majority (39.1%) of the subjects were found to have education/school-related problems, 17.4% had suffered parental separation/improper parenting, 17.4% were demanding children or were pampered in their childhood, 8.7% has faced change in living conditions (came to hostel) prior to onset, 8.7% reported to have peer group problems, and in 8.7%, no identifiable stressor could be found.

Similarly, in second group, majority (66.7%) had family-related/marital problems, 14.8% reported to have work-related stress, 7.4% reported having no children as stressor, and 3.7% reported being unmarried as stressor.


   Discussion Top


Conversion disorder can manifest at any age as seen in the study. In our study, age of the patients ranged from 6 to 54 years. The age criterion was used as conversion is rarely seen in below 5 years of age.[19] The most commonly affected group in our study were young adults (38.0%) between the age of 18–30 years, followed by children and adolescents (36.0%) in the age group of 6–17 years. This corresponds with the findings by Vyas and Bharadwaj,[17] Bagadia et al.,[20] Deka et al.,[21] and Subramanian et al.[22] in their studies on patients with conversion disorder. However, studies from outside India suggest a peak onset in the mid to late 30s.[23],[24],[25]

Occurrence of conversion disorder was found to be higher in females (62.0%) than in males (38.0%) in our study. Similar pattern was observed by Vyas and Bharadwaj,[17] Bagadia et al.,[20] Deka et al.[21] and Subramanian et al.[22] in line with our findings.

Majority of our study subjects were illiterate (44.0%). Among literate ones, most of them had completed only up to 10th standard or had <10 years of formal education (32.0%). Studies by Vyas and Bharadwaj,[17] Bagadia et al.,[20] Deka et al.[21] and Subramanian et al.[22] reported similar findings of majority of the patients being either illiterates or having received education up to primary or high school level.

In our study, the predominant population was of students (46.0%) and housewives (44.0%). Similar finding was reported by Deka et al.[21] and Reddy et al.[26] Similarly, most of our study subjects were married (54.0%). Study by Vyas and Bharadwaj[17] also reported similar findings. However, Studies by Deka et al.[21] and Reddy et al.[26] found unmarried ones to be the predominant group by in contrast to our findings.

Majority (62.0%) of our study subjects were from rural background. Bagadia et al.,[20] Deka et al.,[21] and Gupta et al.[27] also found subjects belonging to rural background as the predominant ones. However, Vyas and Bharadwaj[17] in their study found majority belonged to urban background. This may be due to different settings, in which these studies were conducted.

As high as 78.0% of the study subjects belonged from nuclear families, which could possibly be due to lifestyle pattern in rural areas too changing to a modernized one. Similar findings were reported by Deka et al.[21] and Gupta et al.[27] However, Vyas and Bharadwaj[17] found majority of their study subjects belonged to joint family.

In our study, majority (66.0%) of the study subjects belonged to middle class with respect to their socioeconomic status. In contrast, Deka et al.[21] found majority (75%) of their study subjects belonged to lower socialeconomic status which indicates toward changing epidemiology of conversion disorder with respective to socioeconomic status.

Purely motor symptoms were the most common presentation (84%), of which syncopal attack and pseudo seizures were the commonest. Deka et al.[21] and Gupta et al.[27] also found pseudoseizures as the most common presentations in their studies. However, study by Vyas and Bharadwaj[17] found pain (48.46%) as the most common presentation, whereas Roelofs et al.[28] found paresis/paralysis to be the most common.

Assessing the subjects for psychosocial stressors [Table 3] and [Table 4], it was observed that majority (94.0%) had an identifiable underlying psychosocial stressor preceding the onset of conversion. In study by Deka et al.[21] and Reddy et al.,[26] underlying stressor was found in all the patients (100%), whereas Subramanian et al.[22] in their study found that only 52.5% patients gave history of any obvious precipitating factor.

While education/school-related factors were the major stressors in children and young adults (39.1%), it was the family/marital disharmony-related factors (66.7%) in older adults, leading to conversion. Similar findings were reported by Deka et al.[21] and Reddy et al.,[26] while studies from the western countries report the common stressors to be sexual abuse, emotional, and physical abuse.[29],[30] Even though literature from the west emphasize more on the childhood sexual abuse as a precipitating factor for conversion, this has not been found in any of the Indian studies on conversion which is a matter of further investigation.

Limitations of the study

The sample size was small. Being a cross-sectional study, the pattern of symptomatology in subsequent recurrences could not be studied thereof.


   Conclusion Top


Conversion disorders are more common in children and young adults, students, and housewives, and in those living in a nuclear family, belonging to middle class of socioeconomic status and rural areas. Conversion is significantly more common in females than males (2.5:1). It mostly occurs in the background of increased stressful life events and in the presence of identifiable psychosocial stressors. An understanding of the precipitating psychosocial factors and stressors that overpower the patients' coping abilities have implications for treatment in conversion disorder and enable the clinicians to devise-specific strategies for early intervention and prevention. Further research is required to be conducted with bigger sample to validate and replicate our findings.
