In recent years, numerous studies have highlighted the overlap between autism spectrum disorder (ASD) and catatonia, both from a clinical and pathophysiological perspective. This study aimed to investigate the relationship between the autism spectrum (autistic traits and ASD signs, symptoms, and behavioral manifestation) and Catatonia Spectrum (CS).

A total sample of 376 subjects was distributed in four diagnostic groups. Subjects were assessed with the Structured Clinical Interview for DSM-5, Research Version, the Adult Autism Subthreshold Spectrum (AdAS Spectrum), and CS. In the statistical analyses, the total sample was also divided into three groups according to the degree of autism severity, based on the AdAS Spectrum total score.

A statistically significant positive correlation was found between AdAS Spectrum and CS total score within the total sample, the gender subgroups, and the diagnostic categories. The AdAS Spectrum domains found to be significantly and strongly correlated with the total CS score were hyper–hypo reactivity to sensory input, verbal communication, nonverbal communication, restricted interests and rumination, and inflexibility and adherence to routine. The three groups of different autistic severity were found to be distributed across all diagnostic groups and the CS score increased significantly from the group without autistic traits to the group with ASD.

Our study reports a strong correlation between autism spectrum and CS.

In accordance with the systematics of modern international clinical guidelines (DSM-V, ICD-11), catatonia is qualified as a transnosological formation, which boundaries expandes by including non-psychotic movement disorders (hysterical, affective, negative, etc.). This study presents the psychopathological systematics of movement disorders, based on a new dimensional model of catatonia.

60 patients with an established diagnosis of schizophrenia or SSD (F20, F21, F25.01, F25.11, F25.21, F25.22), catatonic disorders in the structure of which persist throughout the course of the disease or determine the clinical picture of phases.

Clinical, psychometric (BFCRS, SANS, SAPS, HADS), statistic.

Three catatonic syndromes (S.) have been identified. 1. S. of stereotypical catatonia - presented by the mechanism of affiliation with negative symptoms (R between BFCRS Total Score (TS) and Avolition-Apathy SANS – 0,875): tendency to stereotypical activity; general, increasing slowness (SANS avolition-apathy -2,9±0,5; BFCRS TS – 11,1±0,2). 2. S. of parakinetic catatonia - includes paroxysms formes by the mechanism of mental automatism (with the loss of motor acts voluntary effect ) (R BFCRS TS/Persecutory Delusions SAPS– 0,764): irregular polymorphic movement disorders of hyperkinetic and akinetic types, impulsive actions, akinesias (Persecutory Delusions - 2,3±0,4; BFCRS – 19,5±2,3). 3. Affective - catatonic S. - including both the lightest (at the level of recurrent depression) variants of affective-catatonic phases (R BFCRS TS/HADS – 0,732; BFCRS – 5,1±0,4; HADS -15,1±2,4), and more severe affective-catatonic states based on schizoaffective psychoses (R BFCRS TS/SAPS TS– 0,783; BFCRS – 15,3±2,1; SAPS – 3,1±0,2).

Catatonia is not a single dimension, represented by heterogeneous movement disorders, differing both in the mechanism of formation and in the psychopathological structure.

Catatonia is a state of apparent unresponsiveness to external stimuli in a person who is awake. More common in patients with unipolar major depression or bipolar disorder. Common signs: immobility, rigidity, mutism, posturing, excessive motor activity, stupor, negativism, staring, and echolalia. We will discuss a case of a 23 year old male with schizophrenia presented with catatonia and decompensation of his schizophrenia in the context of medication non-compliance. We will discuss findings from litrature pertaining to catatonia and treatment strategies.

- Case study

- Signs of catatonia: immobility, mutism, withdrawal and refusal to eat, staring, negativism, posturing, rigidity, waxy flexibility/catalepsy, stereotypy, echolalia, or echopraxia, verbigeration. - Diagnosis: Clinical, Lorazepam challenge. Bush-Francis Catatonia Rating Scale (BFCRS) - BFCR scale is used as the screening tool. If 2 of the 14 are positive, prompts further evaluation and completion of the remaining 9 items. - Differential Diagnosis include; Neuroleptic Malignant Syndrome, Serotoninergic Syndrome, Malignant Hyperthermia, Akinetic Mutism, Delirium, Parkinson’s disease. - Lorazepam can be scheduled at interval doses until the catatonia resolves. - ECT in combination with benzodiazepines is used to treat malignant catatonia. - Possible complications are Physical trauma, malignant catatonia (autonomic instability, life-threatening), dehydration, pneumonia, pressure ulcers due to immobility, muscle contractions, DVT, PE

Psychiatrists need to be diligent in evaluating patients with Catatonia for other comorbid psychiatric conditions, addressing these conditions and conducting a thorough assessment and prompt treatment.

Mutism is the inability or unwillingness to speak, resulting in an absence or marked paucity of verbal output. Mutism is a common manifestation of psychiatric, neurological, and drug-related illnesses. Psychiatric disorders associated with mutism include schizophrenia, affective disorders, conversion reactions, dissociative states, and dementias. Neurological disorders causing mutism affect the basal ganglia, frontal lobes, or the limbic system.

Outline the importance of setting a differential diagnosis of mutism in the Emergency Room.

Review of scientific literature based on a relevant clinical case.

Male, 58 years old. He has lived in a residence for 3 months due to voluntary refusal to ingest. Diagnosed with paranoid personality disorder. He is refered to the Emergency Service due to sudden mutism. During this day, he has been stable and suitable with a good functionality. For 3 hours he is mutist, oppositional attitude and stiff limbs, refusing to obey simple orders. Hyperalert and hyperproxia. Not staring. After ruling out organic pathology: normal blood tests, negative urine toxins and cranial CT without alterations, he was admitted to Psychiatry for observation and, finally, he was diagnosed with Psychotic Disorder NOS.

Mutism most often occurs in association with other disturbances in behavior, thought processes, affect, or level of consciousness. The most common disorder of behavior occurring with mutism is catatonia. The differential diagnosis of mutism is complex. In some cases the diagnosis will be clarified only by careful observation and after a neurological evaluation. Published studies show neurological disorders presenting with mutism can be misdiagnosed as psychiatric.

Catatonia is one of the most common severe motor syndromes, with an estimated prevalence among psychiatric inpatients of about 15 %. Benzodiazepines and electroconvulsive therapy (ECT) are the most widely studied treatment methods recommended as first-line therapy. We present the case of a 55-year-old female patient with paranoid schizophrenia and severe life-threatening catatonia who remitted under a short series of rTMS.

s. Introduction

The point of resting motor threshold (RMT) for the musculus rectus femoris was determined for the left hemisphere. A straight line 3 cm anterior and parasagittal from that point defined the SMA. A total of three sessions, each with 1000 pulses at intensity 66 % of the RMT, were performed within 24 and 120 hours apart. Stimulation protocol was set to 1Hz in the area of the left SMA with 25 series of 40 pulses, pulse width 25 ms, angle of attack 45°. Hardware: MagVenture, 8-coil “cool-B65 butterfly-shaped coil from Medtronic.

Within 24 hours after the first session, a marked improvement of catatonic symptoms like independent locomotion and verbal communication was recognized. One week after the whole rTMS treatment, a food intake without a gastric tube was possible.

The present case demonstrates that pronounced catatonia may be successfully treated with inhibitory rTMS. Our results underline the importance of non-invasive brain stimulation as a valuable addition to the existing treatment spectrum for catatonia. Future research is empowered to path the way for a significant expansion of treatment.

There are extremely few reported cases of OCD causing catatonia and some of those cases are possibly associated with the somewhat contentious diagnosis of Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus. As there is a symptom overlap between OCD and catatonia some cases of catatonia are possibly being missed, warranting discussion regarding differential diagnosis, symptomatology, and treatment of catatonia and OCD.

We describe a case of a 18-year-old patient who developed severe catatonia secondary to OCD, possibly related to PANDAS/PANS. We discuss the complex work-up, differential diagnosis, and treatment of this patient.

Discussion of a single case and a review of catatonia literature as it relates to OCD and autoimmune disorders.

Our patient was an 18-year-old Ukrainian male who presented with sub-acute onset of decreased movement, decreased oral intake, and inability to speak. He was diagnosed with catatonia of an unclear etiology and treated with high-dose lorazepam at an outside hospital then transferred to our care. Presenting symptoms were then clarified and found to be consistent with OCD, upon which OCD treatment was initiated. The patient’s sub-acute and severe onset of OCD raised the question of a PANDAS/PANS diagnosis, which was further investigated. Ultimately, his symptoms improved with ongoing lorazepam and he was transferred to another hospital for ECT treatment.

OCD has been observed to cause catatonia in extremely rare cases. Diagnosing catatonia associated with OCD is challenging and important as catatonia is associated with significant morbidity and mortality if left untreated. Our patient improved with concurrent treatment of catatonia and OCD.

Withdrawal symptoms are common upon discontinuation of many psychotropic drugs. Catatonia, a neuropsychiatric condition characterized by a number of motor, behavioral, emotional, and autonomic abnormalities, has been described as a withdrawal syndrome in a growing number of case reports, but it is not well recognized. Treatment of catatonia usually includes benzodiazepines and electroconvulsive therapy. Standard consensus states that the use of neuroleptics should be avoided, as they are thought to worsen catatonia.

With this case report, we attempt to contribute to the finding in literature that the withdrawal of clozapine may be associated with catatonia, and how reintroduction of clozapine could be indicated for its treatment.

A clinical case is presented of a 37-year-old female with a history of schizophrenia, presenting with altered mental status and new onset of catatonic signs and symptoms in the setting of a 7-day emetic syndrome. The possibility that vomiting prevented proper absorption of clozapine is postulated, causing the patient to present clinical features compatible with malignant catatonia.

The patient required treatment with benzodiazepines, electroconvulsive therapy and clozapine re-initiation, leading to improvement of catatonic symptoms within a few days.

This case serves as a reminder to consider alternative diagnostic hypotheses in cases of catatonic syndrome unresponsive to standard treatments. When the clinical suspicion of drug withdrawal is high, restarting the discontinued medication, even an antipsychotic agent, may be indicated.

Post-partum depression may occur in the first year after childbirth in approximately 25% of women, at times presenting with psychotic symptoms and catatonic states. Catatonia is a psychomotor syndrome that occurs in association with various neuropsychiatric disorders and can be described according to the characteristics of its manifestation in types such as retarded or agitated.

We report the case of a patient with postpartum depression and catatonic syndrome who, after a session of electroconvulsive therapy, was infected with Sars-COV-2, suspended treatment, and had her condition aggravated with distinct clinical manifestations.

Clinical case report and non-systematic review of articles consulted in the PubMed platform.

A 24-year-old patient develops depressive symptoms and obsessive behaviour 6 months after delivery and deteriorates with mutism, stupor and motor immobility. She was hospitalised and medicated with lorazepam, with no improvement. One session of electroconvulsive therapy was carried out with improvement of the symptoms. Due to an inpatient Covid-19 outbreak, in which the patient was infected, treatment was suspended. During isolation, deterioration of the patient’s condition was observed with psychomotor agitation, bizarre behaviour, and perseverative speech. The patient resumed treatment with ECT, with total remission of the catatonic syndrome and improvement of the affective symptoms.

Catatonic syndromes are relatively rare, but its association with post-partum depression is not so uncommon. The occurrence of different presentations of catatonia, although described as possible in the same episode in the literature, were not found in any clinical studies reviewed, which leads us to conclude that it is an uncommon situation.

COVID-19 infection may lead to encephalopathy and various neurotrophic effects which can result in neuropsychiatric complications. Here, an asymptomatic adolescent female developed acute onset catatonia and psychosis manifesting during the resolution of Covid-19 infection.

Discuss differential diagnosis, medical workup, and initial treatment optimization for acute stabilization.

This 15-year-old female with no previous psychiatric history nor prodromal symptomatology was hospitalized secondary to Covid -19. During the immediate three-month recovery phase following resolution of Covid-19, the patient exhibited gradually increasing anxiety, paranoia, delusions, disorganized behavior, and weight loss leading to re-hospitalization secondary to catatonia. Negative workup included rapid strep test, urinalysis, chest and abdominal x-ray, EEG, and brain MRI. Lumbar puncture revealed elevated WBC of 18 but was unremarkable for NDMA receptor antibodies, CSF HSV, and encephalitis panel. IV steroids, IVIG, and Anakinra were all given without benefit. Inadequate response to olanzapine, clonidine, and lorazepam led to an Index Series of bilateral electroconvulsive therapy (ECT).

The provisional diagnosis of psychotic disorder secondary to COVID-19 infection responded robustly regarding sleep, behavior, and affect by session #6, yet positive symptoms of psychosis persist. Ongoing ECT, psychopharmacology, and narrowing of the differential diagnosis continue.

As more COVID-19 cases evolve during the pandemic, potential post-infectious neuropsychiatric complications should be considered as potentially contributory and kept in a thoughtful differential diagnosis. Regardless of ultimate causation, the acute symptom profile responded robustly to an initial Index Series of ECT.

Many different causes of catatonia are well-documented in medicine. Modern understanding of catatonia has evolved in the last 100 years with the suggestion that there is a root cause in neuroinflammation. This is a case report of a young woman who presented to the emergency department with altered mental status, found to have catatonia responsive to lorazepam, with the underlying etiology being a diagnosis of multiple sclerosis.

A case-based approach is used to support the following learning objectives: - Review the diagnostic criteria for catatonia - Distinguish between simple and malignant catatonia - Review the Bush-Francis Scale - Review available treatment

Mother brings 24-year-old woman into the hospital for altered mental status and changes in behavior including staring spells, periods of withdrawal, refusal to eat, lack of purposeful movement, apraxia, and mutism that worsened 24 hours prior to presentation.

The patient was afebile with negative covid-19 test. Recent diagnosis of Bell’s palsy treated with antivirals and oral steroird, which terminated just prior to presentation. Additionally, patient had outpatient treatment for vertigo. Lumbar puncture was negative for an infectious process. MRI revealed multiple stable white matter lesions in the periventricular, pontine, and subcortical regions, some oriented perpendicular to the corpus callosum.

This case of a 24-year-old woman with catatonia brought an opportunity to retrospectively review a case in detail in order to feature learning objectives that review very important considerations in the evaluation, differential diagnosis, symptom tracking, and treatment of catatonia. The future of research in catatonia is bright and diverse.

Catatonia is a neuropsychiatric disorder characterized by motor, behavioral and autonomic changes. It is associated with several psychiatric disorders, including dementia. Catatonia is an underdiagnosed syndrome, so it is important to draw attention to it. Here, we review a case of a patient admitted to our psychiatric department with a clinical presentation compatible with catatonia. After proper treatment, further assessment revealed dementia.

This work aims to describe a case of catatonia in a patient with dementia.

Bibliographic research using Pubmed®. Clinical file consultation and patient interviews.

Catatonia is a disorder that was already been described as part of several types of dementia. We present a 69-year-old female patient, admitted to our psychiatric department with clinical presentation compatible with catatonia. To admission, she presented some typical complications resulting from long immobility such as pressure ulcers and nutritional deficiencies. During the hospitalization, she developed a urinary infection and there was the need to tube feeding. She was treated with benzodiazepines and improved. Further assessment revealed dementia.

Catatonia in dementia is not uncommon, although it is an underdiagnosed syndrome, and when treated early and properly it has a good prognosis.

Catatonia has been increasingly described in cases of COVID-19; we therefore aimed to investigate the evidence for catatonia in patients with COVID-19. We searched PubMed, EMBASE, PsycINFO, BIN and CINAHL databases for articles published in English, from the initial descriptions of the COVID-19 pandemic to January 2022.

A total 204 studies were identified, 27 (13%) of which met the inclusion criteria. The evidence available was based on case reports. The articles included in this review identified a total of 42 patients, ranging from the ages of 12 to ≥70 years, with confirmed or possible catatonia during or after a COVID-19 infection.

This review provides valuable information to clinicians in medical practice for treating patients with COVID-19, and a foundation for further research for this uncommon syndrome of COVID-19.
