Catatonia is a well-known neuropsychiatric clinical condition. The most common cause of catatonia is psychiatric illnesses like schizophrenia and depression. The important clinical features of catatonia are ambitendency, automatic obedience, catalepsy, echolalia, echopraxia, rigidity, posturing, etc., Several organic causes are also responsible for catatonic symptoms, which we don't keep in our mind in our day-to-day practice. Here, we described case series of catatonia that are related to organic etiological factor.

| Introduction|| |
The concept of catatonia was first described by Kahlbaum (1874). Catatonia is a well-known neuropsychiatric syndrome, and it's important clinical features are mutism, stupor, refusal to eat or drink, posturing and excitement or hypokinesia. However, it has been suggested that catatonia is underrecognized and underdiagnosed. Nowadays, the introduction of antipsychotics has reduced significantly the incidence of catatonia but it is still not uncommon. The exact cause of catatonia has not been detected till now, but some hypotheses have been offered. A "topdown modulation" of basal ganglia due to deficiency of cortical gamma amino butyric acid, the primary inhibitory neurotransmitter of the brain, may explain the motor symptoms of catatonia. Catatonia is also caused by a sudden and massive blockade of dopamine. In chronic catatonia with prominent speech abnormalities, positron emission tomography has identified abnormalities in metabolism bilaterally in the thalamus and frontal lobes. Identification of the underlying organic causes, if any, should be a priority in the management of catatonia. Prompt treatment in the early phases of catatonia is crucial to obtain a lasting abatement of symptoms. We present four cases to highlight the organic causation of catatonia and the importance of early recognition of such cases.
| Case Reports|| |
N.S, a 40-year-old housewife, admitted in Institute of Postgraduate Education and Research (IPGME and R) Hospital, Kolkata with complaints of weakness and lethargy followed by gradual withdrawal from household activities for last 8 months. Eventually, she became mute and showed some kind of unusual posturing. Physical examination was grossly normal except pallor. Mental state examination revealed some catatonic features including of waxy flexibility, mutism, posturing and rigidity. Blood examination showed hemoglobin 9 g/dl with significant raised mean corpuscular volume (MCV). Other laboratory investigations including thyroid function tests, liver function tests, serum electrolytes, renal function tests, C-reactive protein and cranial computed tomography (CT) were normal. She was not responded at all with adequate important treatment varieties such as a course of antipsychotic like risperidone, intramuscular lorazepam injection, modified electroconvulsive therapy, and psychotherapy. As her blood parameter was very much suggestive of folate and Vitamin B12 deficiency, we started hydroxycobalamine 1 mg intramuscular injection on every alternate day and tablet folic acid orally 5 mg daily. After continuous 2 weeks of treatment with this regime, she showed marked improvement in all aspects of catatonia. Her hemoglobin level was measured subsequently, and it was 12.5 mg/dl with normal MCV.
A.S, a 68-year-old Hindu married depressive male was on treatment with 40 mg fluoxetine daily. After 2 weeks of treatment, he developed some catatonic features such as stupor, rigidity, cataplexy, and posturing. He was not febrile at all. His serum sodium level was 112 meq/L, and potassium level was 4.1 meq/L. Other important investigations such as liver function tests, serum creatinine level, complete blood count, chest X-ray, and thyroid function tests were within normal range. Fluoxetine was suspected as the offending agent to cause hyponatremia. Therefore, it was discontinued, and the patient was on supplementary sodium therapy. Miraculous improvement of catatonic symptoms was noted after correction of hyponatremia. Subsequently, the patient was discharged with tablet mirtazapine as an antidepressive agent.
An 18-year-old school girl, T.D, admitted in IPGME and R, Hospital due to sudden onset mutism, posturing and negativism. She had a history of fever for 5 days and then she rapidly developed all these catatonic features. She also had an episode of seizure on the day of admission to the psychiatry unit. She was febrile, but the rest of the physical examination was normal except for catatonic symptoms. Electroencephalography showed slow waves and CT of the brain was normal. Cerebrospinal fluid analysis for polymerase chain reaction was confirmed a positive infection with herpes simplex virus type 1. She was on intravenous infusion of acyclovir 10 mg/kg body weight in every 8 h interval for 10 days and oral antiepileptic medication (sodium valproate). Gradually, she made a slow but complete recovery.
A 15-year-old girl, S.S, attended IPGME and R outpatient department with behavioral changes. She was smiling to self and had been withdrawn from social activities over the previous 3 months. She also exhibited posturing and catalepsy. Her physical examination was normal except for a facial butterfly rash and catatonic features. She was treated with risperidone at the district hospital with poor response. Investigations revealed a high erythrocyte sedimentation rate of 120 mm/1st hour. Anti-Smith and anti-double-stranded DNA antibodies were positive. Hence oral prednisolone was started. Her catatonic symptoms resolved after adding prednisolone to the treatment regime.
| Discussion|| |
Several medical, neurological and metabolic disorders are associated with or etiologically related to the clinical syndrome of catatonia.,, Pernicious anemia is associated with psychiatric conditions such as mood disorder, psychosis and dementia and catatonia., Vitamin B12 deficiency as a causative factor of catatonic symptoms has also been established. Our first case supports the view that there is an association between catatonia and Vitamin B12/folic acid deficiency.
Metabolic abnormalities such as hyponatremia may cause catatonia also. Our second patient's catatonic symptoms are likely to have been due to hyponatremia. The importance of performing serum electrolytes in such patients is highlighted here.
Viral encephalitis and meningitis are not uncommon conditions in our country, India. The presentation may vary from mild symptoms such as headaches to severe presentation such as delirium and seizures. Our third patient developed catatonic symptoms due to viral encephalitis and catatonic symptoms resolved following anti-viral treatment. This case illustrates the importance of considering the possibility of central nervous system infections in the assessment of catatonia.
Patients with systemic lupus erythematosus (SLE) may commonly present with psychiatric and neurological symptoms. Although rarely seen, patients with SLE presenting with catatonia. Our fourth patient presented with catatonic symptoms following SLE and the catatonic symptoms improved with steroids. This case again illustrates the importance of excluding autoimmune disorders such as SLE and the need to perform relevant investigations in the assessment of catatonia, particularly in young female patients.
| Conclusions|| |
Although many catatonic presentations are due to psychiatric conditions, it is mandatory to look for organic causes, as early detection and treatment of them will certainly improve the prognosis.
