Quetiapine responsive catatonia in an autistic patient with comorbid bipolar disorder and idiopathic basal ganglia calcification

Affected cortico-striatal-cerebellar network in schizophrenia with catatonia revealed by magnetic resonance imaging: indications for electroconvulsive therapy and repetitive transcranial magnetic stimulation

Catatonia is a psychomotor syndrome that can occur in a broad spectrum of brain disorders, including schizophrenia. Current findings suggest that the neurobiological process underlying catatonia symptoms in schizophrenia is poorly understood. However, emerging neuroimaging studies in catatonia patients have indicated that a disruption in anatomical connectivity of the cortico-striatal-cerebellar system is part of the neurobiology of catatonia, which could serve as a target of neurostimulation such as electroconvulsive therapy and repetitive transcranial magnetic stimulation.

Diagnostic overshadowing clouding the efficient recognition of pediatric catatonia: a case series

Catatonia is a neuropsychiatric condition that causes disruption of movement, emotion, and behaviors. Children and adults with underlying psychiatric conditions are particularly susceptible to developing catatonia, which may result in medical and psychiatric complications. Although catatonia research has been growing at a rapid rate in the last 20 years, it continues to be met with inefficiencies in its diagnosis and incertitude in its treatment. In the pediatric population, catatonia is plagued by diagnostic overshadowing, where the catatonia is erroneously attributed to existing pathologies that lead to a prolonged disease state. This paper describes three pediatric patients with catatonia that fell victim to diagnostic overshadowing. More rigorous training and education are imperative to improve the efficient recognition and treatment of children with catatonia.

Clinical features of bipolar disorder with idiopathic basal ganglia calcification: a review of case reports in the literature

Although idiopathic basal ganglia calcification (IBGC) is associated with various neuropsychiatric disturbances including several cases of bipolar disorder (BD), there has been no systematic review of clinical features of patients with BD and comorbid IBGC. We undertook a literature search to identify case reports of these patients. Most cases showed complex syndromes comprising not only mood disturbance but also cognitive disability and motor symptoms limited to depressive state and had favorable treatment response. These patients should have a careful and repeated psychiatric, neurological, and cognitive assessment to determine an optimal diagnostic and treatment approaches at each clinical stage.

Two Sides of the Same Coin: A Case Report of First-Episode Catatonic Syndrome in a High-Functioning Autism Patient

Background: Catatonic phenomena such as stupor, mutism, stereotypy, echolalia, echopraxia, affective flattening, psychomotor deficits, and social withdrawal are characteristic symptoms of both schizophrenia and autism spectrum disorders (ASD), suggesting overlapping pathophysiological similarities such as altered glutamatergic and dopaminergic synaptic transmission and common genetic mutations. In daily clinical practice, ASD can be masked by manifest catatonic or psychotic symptoms and represent a diagnostic challenge, especially in patients with unknown or empty medical history. Unclear diagnosis is one of the main factors for delayed treatment. However, we are still missing diagnostic recommendations when dealing with ASD patients suffering from catatonic syndrome. Case presentation: A 31-year-old male patient without history of psychiatric disease presented with a severe catatonic syndrome and was admitted to our closed psychiatric ward. After the treatment with high-dose lorazepam and intramuscular olanzapine, catatonic symptoms largely remitted, but autistic traits persisted. Following a detailed anamnesis and a thorough neuropsychological testing, we diagnosed the patient with high-functioning autism and catatonic schizophrenia. The patient was discharged in a remitted state with long-acting injectable olanzapine. Conclusion: This case represents an example of diagnostic and therapeutic challenges of catatonic schizophrenia in high-functioning autism due to clinical and neurobiological overlaps of these conditions. We discuss clinical features together with pathophysiological concepts of both conditions. Furthermore, we tackle social and legal hurdles in Germany that naturally arise in these patients. Finally, we present diagnostic "red flags" that can be used to rationally select and conduct current recommended diagnostic assessments if there is a suspicion of ASD in patients with catatonic syndrome in order to provide them with the most appropriate treatment.

The use of quetiapine in treatment of acute psychotic symptoms in an adolescent patient with primary brain calcification: a case report

BACKGROUND

Primary brain calcification (PBC), a neurodegenerative disorder with characteristic calcium deposits in the basal ganglia and other brain areas, typically presents with various neurological and psychiatric symptoms in the fourth or fifth decade of life or later. We present the case of a patient with psychiatric manifestations much earlier than usual, in the second decade of life.

CASE PRESENTATION

The case of an adolescent female with acute psychotic symptoms, emotional instability, disorganized and suicidal behavior, stereotypical movements, below average intelligence and a three-year history of headaches is reported. Among others, the presentation included tactile hallucinations with secondary hypochondriacal delusions, which are rarely described in this diagnosis. Massive calcinations in the area of the basal ganglia and thalamus were determined by computerized tomography. Other causes of brain calcification were excluded. No causative mutations were found in selected genes. All the symptoms apart from lower intellectual abilities improved with quetiapine and sertraline. The patient showed no side effects.

CONCLUSIONS

This case report highlights the successful use of quetiapine for symptomatic treatment of acute psychosis due to PBC in an adolescent without exacerbating extrapyramidal symptoms.

Catatonia in children and adolescents: New perspectives

INTRODUCTION

Catatonia is a rare and severe psychomotor condition in children and adolescents. In the current report, we aimed to review the recent literature.

METHOD

Using a PRISMA approach, we searched MEDLINE between 1982 and 2017 using the keywords 'CATATONIA' and 'CHILD' or 'ADOLESCENT'. In total, we reviewed 130 reports (controlled study, N=4; clinical chart, N=23; case report, N=54; and editorial/review, N=42).

RESULTS

Several aspects seem to be age specific: (1) although the clinical presentation resembles that in adults, some symptoms are important in children and adolescents (e.g., psychomotor regression). (2) Associated disorders are similar to that found in adults; however, schizophrenia is more frequently observed than mood disorder. Additionally, a history of neurodevelopmental disorders maybe encountered. (3) Morbidity and mortality are among the worst in child psychiatry. (4) Underlying organic conditions are highly prevalent (>20% of the cases), and their search is warranted because some diagnoses may result in specific treatments (e.g., immune-suppressor therapy for autoimmune conditions). (5) Symptomatic approaches - high dose of benzodiazepines and electroconvulsive therapy (ECT) - are as efficient in children or adolescents as they are in adults, but this finding needs to be acknowledged because a resistance against the use of ECT or high-dose medication exists among child psychiatrists.

DISCUSSION

Recent advances in child and adolescent catatonia research have offered major improvements in understanding catatonia and in new therapeutic opportunities. The syndrome is rare, but these advances need to be acknowledged in order to direct patients to centers that have developed a specific expertise.

Motor dysfunction as research domain across bipolar, obsessive-compulsive and neurodevelopmental disorders

Although genuine motor abnormalities (GMA) are frequently found in schizophrenia, they are also considered as an intrinsic feature of bipolar, obsessive-compulsive, and neurodevelopmental disorders with early onset such as autism, ADHD, and Tourette syndrome. Such transnosological observations strongly suggest a common neural pathophysiology. This systematic review highlights the evidence on GMA and their neuroanatomical substrates in bipolar, obsessive-compulsive, and neurodevelopmental disorders. The data lends support for a common pattern contributing to GMA expression in these diseases that seems to be related to cerebello-thalamo-cortical, fronto-parietal, and cortico-subcortical motor circuit dysfunction. The identified studies provide first evidence for a motor network dysfunction as a correlate of early neurodevelopmental deviance prior to clinical symptom expression. There are also first hints for a developmental risk factor model of these mental disorders. An in-depth analysis of motor networks and related patho-(physiological) mechanisms will not only help promoting Research Domain Criteria (RDoC) Motor System construct, but also facilitate the development of novel psychopharmacological models, as well as the identification of neurobiologically plausible target sites for non-invasive brain stimulation.

The Differential Diagnosis and Treatment of Catatonia in Children and Adolescents

LEARNING OBJECTIVES

After participating in this activity, learners should be better able to:• Assess the etiologies associated with catatonia in children and adolescents• Evaluate the differential diagnosis of pediatric catatonia• Interpret the literature regarding the treatment of children and adolescents with catatonia OBJECTIVE: Pediatric catatonia is associated with many medical and psychiatric conditions. Mortality is high, and proper treatment can be lifesaving. Catatonia is increasingly recognized in pediatric populations, in which about 20% of cases are related to underlying medical conditions. To minimize morbidity, clinicians must rule out underlying disorders while simultaneously managing symptoms and causes. In our review we discuss (1) recommendations to aid rapid decision making, both diagnostic and therapeutic, (2) emergent conditions and management, (3) disorders associated with pediatric catatonia, including developmental, acquired, idiopathic, and iatrogenic etiologies, (4) available treatments, and (5) medicolegal considerations.

METHODS

Initial PubMed search without date constraints using MeSH terms related to pediatric catatonia, with subsequent searches on pertinent subtopics using PubMed and Google Scholar.

RESULTS

Pediatric catatonia is a dangerous but treatable neuropsychiatric condition. Psychiatrists need to be aware of differential diagnoses and to be able determine appropriate treatment within a short time frame. With prompt diagnosis and treatment, outcomes can be optimized.

CONCLUSION

Pediatric catatonia is underdiagnosed and requires rapid evaluation and management.
