   Abstract 

Despite the availability of electroconvulsive therapy (ECT) and being one of the safest modalities of treatment, the use of ECT is still underused in patients with mental retardation with catatonia. However, the available limited literature suggests that ECT can be used safely with proper monitoring and assessment, especially in those presenting with catatonia in mental retardation. We treated a 17-year-old boy who presented to us with catatonia with mental retardation with a course of 12 ECT, with which the catatonia resolved completely. Review of the literature suggests that the occurrence of catatonia is rare in mental retardation. However, ECT can be used in a rare case with precautions.

   Introduction Top


The incidence and prevalence of primary psychiatric illness in children and adolescents with mental retardation are much higher than the general population.[1],[2] Use of electroconvulsive therapy (ECT) is very limited in patients with mental retardation, however it has been used very effectively in the general population.[3],[4],[5],[6],[7] Since last one decade, the trends favor the ECT’s efficacy, but still, this method is rarely used.[4],[8] However, studies have also failed to show the clear evidence of brain insult following treatment with ECT.[3] There are few case reports or case series that report of mental retardation associated with catatonia without any association with mood or schizophrenia disorder.[8],[9],[10],[11] The limited data suggests that catatonia with mental retardation may respond to benzodiazepines and or ECT.[12]

However, limited literature is available on the use of ECT in adolescents with mental retardation with catatonia. Here in this case report, we present a case report of a patient of mental retardation with catatonia without any affective or psychotic illness, and we also review the literature in the use of ECT in an adolescent with mental retardation.


   Case Report Top


A 17-year-old boy presented with an insidious onset of illness since birth. The patient was born at 9 months by emergency cesarean section in view of meconium-stained liquor and fetal distress. He cried after 5–10min at birth after tactile stimulation. His birth weight was 3kg; after 24h of birth, he had recurrent episodes of seizures. The provisional diagnosis was kept as hypoxic ischemic injury. He was on antiepileptic drugs with good compliance. He had a significant developmental delay in all domains according to his appropriate age. At the age of 2 years, he again started having episodes of seizures and was managed accordingly by a pediatric neurologist. The developmental milestone delay continued as such. The frequency of seizures decreased significantly but would occur after every 6–8 months with good compliance. The last episode of seizure occurred at the age of 11 years. At the age of 11 years, he started to go to a special school for mentally retarded children. He had significant improvement in his behavior such as helping his mother with household chores, interacting with other children, playing games, counting the things, and emotional reactivity to external stimuli. This pattern continued till the age of 14 years. At the age of 14½ years, antiepileptic drugs were stopped gradually over a period of 2–3 months and maintained well for the next 2 years. Reportedly, he was scolded by a school teacher for not following their commands. Following which, he stopped going to school, would appear fearful, and would keep on saying “I will not go to school.” If a family member asked about the school, he would become aggressive, say teachers are bad, and will harm him. After 4–5 days of the same, he became mute, staring at one place with a fixed gaze, and not responding to external stimuli. He would walk very slowly, would urinate in clothes, and would keep on sitting in spoilt clothes for hours together. Other than these symptoms, drooling of saliva, negativism, ambitendency, and posturing were also present. Injection lorazepam test dose carried out with 2mg had significant improvement. He was started on tablet lorazepam 6mg/day. Initially he showed response but later he did not show any response. In view of the same, he was admitted to the inpatient unit of the psychiatry ward of the hospital. On mental status examination, the patient was found to have staring, negativism, automatic obedience, posturing, rigidity, ambitendency, mutism, negativism, staring, and drooling of saliva. His Bush–Francis Catatonia Rating Scale (BFCRS) score was 26. On investigation, hemogram, liver function test, renal function test, serum electrolyte levels, thyroid function test, ultrasound abdomen, X-ray chest (posterior-anterior view), and electrocardiogram did not reveal any abnormality. Magnetic resonance imaging of brain was suggestive of a reduction in the volume of the white matter with periventricular leucomalacia due to an old hypoxic insult. From clinical history and mental status examination, a diagnosis of mild mental retardation with catatonia was kept (epilepsy in the past). The dose of lorazepam was increased to 7mg thrice in a day. After giving a dose, he had significant improvement; BFCRS score came down from 26 to 6. Tablet olanzapine (5mg) was also started considering the fearfulness and odd behavior as psychotic symptoms, which occurred before the appearance of catatonic symptoms. The effect would last only for a few hours. He continued on tablet lorazepam 24mg/day in divided dose but did not show much improvement. It should also be noted that, despite this high lorazepam dose, he never became sedated or had any symptoms of respiratory suppression. Following this, he was considered for ECT.

His parents were educated about the ECT procedure and the indications for the same in the patient. A written informed consent was obtained from his father as he was his guardian. An attempt was also made to take the patient’s assent before initiating ECTs, but that could not be carried out considering his condition. He was then started on bilateral modified ECT.

As his clinical condition improved, his assent was sought for subsequent ECTs. During this period, the patient did not have any subjective complaints or objective signs of memory impairment or post-ECT delirium or other complications. By his 12th ECT, his BFCRS score came down from 26 to 1, and following this, two more ECTs were given. After attainment of a plateau of clinical response, ECTs were stopped. On mental status examination, he had no active psychopathology at the end of the course of ECT. He was discharged after 1 week of observation. He was continued on tablet olanzapine 15mg/day after discharge. At home, he again started going to school, with adequate function as noted before the occurrence of the illness.


   Discussion Top


Despite the increased prevalence of mental illness in patients with mental retardation, the use of ECT is approximately three times less in patients with mental retardation.[1],[2],[3],[4] Since the last few decades, increasingly consistent trends support the efficacy of ECT in the patient with mental retardation dual diagnosis.[4],[7] The reason of underuse can be many, such as difficulty in obtaining informed consent, legal aspects, lack of empirical data, and organic brain damage, and moreover, the international guidelines have not made any recommendation for ECT in mental retardation.[7],[12],[6]

There are approximately 100 published cases in the literature, which were managed with the use of ECT in mental retardation. Most of them are either case series or case reports.[4],[13] No systematic review, case-controlled, or randomized controlled studies are available.[14],[15]

The result of this case report showed that ECT can be used effectively in a patient with intellectual disability with catatonia. There is a need to reform the guideline for the use of ECT in mental retardation. The clinicians should take the initiative to carry out more research such as a randomized controlled trial and follow-up studies. In view of the same, rather than banning the use of ECT in adolescents, it would be better to leave the decision to use and not to use ECT in adolescents in the hands of the clinicians.
