Malignant Catatonia Triggered by Acute Psychological Traumatic Experience in a Patient With Schizophrenia: A Case Report
(2025) Ülkevan, Tuba; Altındağ, Hülya; Tapan, Suheda
Malignant catatonia is defined as catatonia accompanied by hyperthermia and/or autonomic instability. Catatonia can develop in association with psychiatric disorders such as schizophrenia, bipolar disorder, and major depressive disorder, as well as various medical and neurological conditions. However, our knowledge regarding the role of acute traumatic experiences in the development of catatonia remains limited. This case report discusses a presentation of malignant catatonia triggered by an acute psychological trauma in a patient with schizophrenia in remission. A 41-year-old male patient has been followed with a diagnosis of schizophrenia since 2003. Following an acute psychological traumatic event, the patient developed withdrawal, reduced speech, refusal to eat and drink, and generalized rigidity. Upon examination, the patient exhibited catatonic stupor, rigidity, mutism, negativism, and vital signs indicating hyperther - mia and hypertension. Based on these findings, a diagnosis of malignant catatonia was considered. The patient was administered electroconvulsive therapy. After eight sessions of electroconvulsive therapy, a significant improvement in the patient's clinical symptoms was observed. Traumatic experiences may contribute to the development of malignant catatonia through mechanisms such as acute threat perception, inflammatory responses, autonomic instability, and dysregulated dopaminergic signaling
The Role of Thought Suppression in Conversion Disorder in Relation To Depression, Symptom Interpretation and Sleep Hygiene: a Case-Control Study
(Univ Sao Paulo, inst Psiquiatria, 2020) Ozdemir, Pinar Guzel; Kirli, Umut; Isik, Mesut; Tapan, Suheda
Background: Thought suppression has been associated with a number of psychiatric disorders. However, the association with conversion disorder (CD) has not been investigated yet. Objective: To investigate the role of thought suppression in CD. Methods: Eighty consecutive outpatients with a diagnosis of CD and sixty age, sex and neighborhood-similar controls were evaluated using Beck Depression Inventory-I (BDI-I), White Bear Suppression Inventory (WBSI), Symptom Interpretation Questionnaire (SIQ) and Sleep Hygiene Index (SHI). Cases and controls were compared in regard to thought suppression scores considering their status of high depression scores via a logistic regression model. The reciprocal associations of thought suppression with other clinical dimensions in CD were assessed. Finally, structural equation modelling was applied to untangle the possible connections. Results: CD patients had significantly higher scores of thought suppression than the control group. However, the difference was below the significance level when CD patients without comorbid high depression scores were taken into account. Thought suppression was associated with the clinical severity of CD. According to the structural equation model, older age and somatic attributions to the common bodily sensations were the significant correlates of thought suppression among CD patients. Discussion: Thought suppression may be considered as a non-specific marker of clinical severity in CD.
Vitamin B12, Folate Levels and Somatoform Dissociation in Conversion Disorder
(Pakistan Medical Assoc, 2020) Ozdemir, Pinar Guzel; Gur, Tugba; Cokluk, Erdem; Isik, Mesut; Tapan, Suheda
Objective: To evaluate the association of folate and vitamin B12 levels in patients with conversion disorder, and to illuminate the aetiology of conversion disorder by examining depression and somatoform dissociation. Method: The case-control study was conducted from March 2014 to May 2015 at the Medical Centre of Yuzuncu Yil University, Van, Turkey, and comprised patients diagnosed with conversion disorder and healthy controls. Blood samples were taken from both groups for vitamin B12 and folate levels. Data was collected using the Beck Depression Inventory and Somatoform Dissociation Scale. Data was analysed using SPSS 18. Results: Of the 100 subjects, 55(55%) were cases with a mean age of 27.05 +/- 9.04 years and 45(45%) were controls with a mean age of 26.56 +/- 5.96 years. The mean level of B12 was 283.93 +/- 122.96 in cases and 324.62 +/- 128.82 in controls (p=0.05). The mean level of folic acid was 5.47 +/- 1.84 in cases and 6.07 +/- 2.26 in controls (p>0.05). Conclusions: Physicians need to be vigilant about vitamin B12 levels in patients with conversion symptoms.
