Adolescent catatonia successfully treated with Lorazepam and aripiprazole

Zolpidem in treatment resistant adolescent catatonia: a case series

Catatonia is a well-established psycho-motor disorder occurring in the background of various psychiatric and medical disorders. Catatonia is commonly associated with psychiatric disorders, especially affective disorders followed by schizophrenia. However, almost 20% occur in the background of different medical and neurological disorders which need to be properly examined and investigated. Catatonia is a serious medical and psychiatric emergency condition; most probably caused by alteration in GABAergic circuits and basal ganglia. If untreated, catatonia can cause life threatening complications like dyselectrolemia, respiratory aspiration, venous thromboembolism, acute renal failure and cardiac arrest because of poor oral intake, immobility and muscular rigidity. The risk of mortality or serious life threatening events further increases in cases of children and adolescents. In children and adolescents, thus, it becomes even more important to diagnose catatonia early and start appropriate treatment. Lorazepam is considered to be the first line treatment and is safe both in adults and children. But evidence is scarce for treatment of lorazepam-resistant adolescent Catatonia. In this report we discuss two adolescent patients diagnosed with catatonia with no medical or neurological disorders in the background. Neither of the patients responded to lorazepam alone or even after augmentation with second generation antipsychotic (olanzapine). Zolpidem, like lorazepam, has a positive allosteric effect on GABA A Receptors (GABAAR) and has been used in some cases successfully to treat resistant catatonia. Here we used zolpidem 30 mg/day in divided doses with marked improvement in few days in all the symptoms. Both cases were discharged on zolpidem extended release (ER) three times a day and maintained well through the next two follow ups in over a two month period. Zolpidem can be a good alternative for children and adolescents in resistant cases.

Switching to aripiprazole for the treatment of residual mutism resulted in distinct clinical courses in two catatonic schizophrenia cases

OBJECTIVES

The efficacy of a partial agonist for the dopamine D₂ receptor, aripiprazole, for catatonia in schizophrenia has been reported.

METHODS

We report distinct clinical courses in challenging aripiprazole to treat residual mutism after severe catatonic symptoms improved.

RESULTS

In the first case, mutism was successfully treated when the patient was switched from olanzapine to aripiprazole. In contract, switching to aripiprazole from risperidone aggravated auditory hallucinations in the second case.

CONCLUSIONS

We will discuss the benefits and risks of using aripiprazole for the treatment of catatonic schizophrenia and the possibility of dopamine supersensitivity psychosis.
