Takotsubo cardiomyopathy (tcmp) is an acute, reversible disruption of the left ventricular systolic function. In many respects the clinical presentation closely resembles acute coronary syndromes (myocardial infarction). tcmp is a syndrome with a pathophysiology that is not fully understood and which seems to be closely associated with psychiatric disorders or psychological problems. We present a case in which a patient with several risk factors developed a tcmp and a depression with psychotic features, followed by catatonia...

Catatonia is under-diagnosed in psychiatric settings. No studies have explored the under-diagnosis of catatonia in general hospitals. The authors conducted a retrospective chart review using DSM-5 criteria to diagnose catatonia in medical inpatients between 2011 and 2013. Of 133 case subjects meeting DSM-5 criteria for catatonia retrospectively, 79 had never been diagnosed and 54 had a documented diagnosis. Multiple logistic regression revealed that psychiatry consultation significantly decreased the odds of under-diagnosis of catatonia, whereas presence of agitation, grimacing, or echolalia increased the likelihood of under-diagnosis...

Antibody-mediated encephalopathies associated with serum or cerebrospinal fluid antibodies directed against neuronal structures may present with a multitude of neuropsychiatric syndromes. Although some of the antibody-driven conditions are now well recognized in adults (eg, N-methyl-D-aspartate receptor antibody encephalitis), the spectrum of neuropsychiatric manifestations in the pediatric population is less clear. Psychosis, confusion, catatonia, and additional behavioral changes, along with seizures, encephalopathy, and movement disorders, may be initial manifestations or concurrent features in all age groups...

Apart from the term 'involuntary movements', the term 'movement disorders' encompasses not only classical hyperkinesias but also hypokinesias including catalepsy or apraxia. It enables us to understand abnormal movements by their phenomena instead of by their localization. To advance the grasping of movement disorders, we discuss the clinical and pathophysiological features of abnormal movements in catatonia/catalepsy, anti-NMDAR encephalitis, paroxysmal dyskinesias, stiff person/leg syndrome, corticobasal degeneration/syndrome, and hysteria...

PURPOSE OF REVIEW: Self-injurious behaviour (SIB) is a devastating condition frequently encountered in autism spectrum disorders (ASDs) that can lead to dangerous tissue injury and profound psychosocial difficulty. An increasing number of reports over the past decade have demonstrated the swift and well tolerated resolution of intractable SIB with electroconvulsive therapy (ECT) when psychopharmacological and behavioural interventions are ineffective. The current article provides a review of the salient literature, including the conceptualization of repetitive self-injury along the catatonia spectrum, and further clarifies the critical distinction between ECT and contingent electric shock...

The underlying cellular mechanisms of catatonia, an executive "psychomotor" syndrome that is observed across neuropsychiatric diseases, have remained obscure. In humans and mice, reduced expression of the structural myelin protein CNP is associated with catatonic signs in an age-dependent manner, pointing to the involvement of myelin-producing oligodendrocytes. Here, we showed that the underlying cause of catatonic signs is the low-grade inflammation of white matter tracts, which marks a final common pathway in Cnp-deficient and other mutant mice with minor myelin abnormalities...

White matter abnormalities are prevalent in neuropsychiatric disorders such as schizophrenia, but it is unclear whether these abnormalities represent a cause or consequence of these disorders. Reduced levels of the myelin protein 2'-3'-cyclic nucleotide 3'-phosphodiesterase (CNP) are associated with the schizophrenic symptom catatonia in both humans and mouse models. In this issue of the JCI, Janova et al. show that reduced CNP levels correlate with catatonia and white matter inflammation in human subjects...

BACKGROUND: Electroconvulsive therapy is indicated in cases of catatonic schizophrenia following a failure of the challenge test with lorazepam or Zolpidem®. Some patients need maintenance treatment with ECT. Repetitive Transcranial Magnetic Stimulation (rTMS) and anodal Transcranial direct-current stimulation (tDCS) might be effective against catatonia. OBJECTIVE: Consider an alternative to ECT for a refractory patient. REVIEW: Twenty-one articles were identified mainly based on case reports series were found using search on Medline, Google Scholar, PsychInfo, CAIRNS...

An 82-year-old man was admitted to the emergency department following bizarre behaviour. Police had noticed him driving erratically through his village. He did not stop when instructed, drove slowly home and appeared 'vacant' on questioning. While in hospital, he had approximately 15 episodes of catatonia, involving rigidity, negativism, mutism except echolalia and perseveration, automatic obedience and utilisation phenomena, lasting 2-20 min each. Between episodes, he was amnestic but otherwise well. Electroencephalography demonstrated bifrontal slowing with left-sided emphasis, and captured two focal onset partial seizures with the clinical correlate of the syndrome described above...

Although catatonia is a well-known psychiatric syndrome, there are many possible systemic and neurological etiologies. The aim of this case report was to present a case of a patient with cerebral venous sinus thrombosis and infarction in which catatonia was the clinical manifestation of a possible nonconvulsive status epilepticus. To our knowledge, only one such case has been reported in the literature, which had a simplified diagnostic investigation. It is important to correctly recognize the organic cause underlying catatonia in order to treat the patient as soon as possible thereby improving outcome...

Baclofen is a centrally acting gamma-aminobutyric acid receptor agonist with many therapeutic uses in neurology and psychiatry. An overdose of baclofen is known to cause serious side effects such as encephalopathy, seizures, respiratory depression, and delirium. Association of baclofen with psychosis has also been reported. In this case report, we are highlighting the manifestation of catatonic features in addition to psychosis following baclofen overdose.

Catatonia is an independent syndrome that co-occurs with several mental and medical conditions. We performed a systematic literature review in PubMed/Scopus until February 2017 and meta-analyzed studies reporting catatonia prevalence. Across 74 studies (cross-sectional = 32, longitudinal = 26, retrospective = 16) providing data collected from 1935 to 2017 across all continents, mean catatonia prevalence was 9.0% (k = 80, n = 110764; 95% CI = 6.9-11.7, I2 = 98%, publication bias P < .01), decreasing to 7...

Despite a growing body of evidence on motor dysfunction in schizophrenia spectrum disorders, the neuronal correlates of genuine motor abnormalities (GMA) are not fully elucidated at present. Moreover, the clinical relevance of a potential "motor intermediate phenotype" remains controversial. This systematic review aims at characterizing a "motor intermediate phenotype" in schizophrenia spectrum disorders. The second goal of this systematic review is to discuss GMA-associated brain alterations as potential biomarkers of psychosis risk syndrome and manifest motor symptoms against the background of current neuroimaging evidence...

Catatonia is a clinical syndrome characterized by symptoms such as immobility, mutism, stupor, stereotypy, echophenomena, catalepsy, automatic obedience, posturing, negativism, gegenhalten and ambitendency. This syndrome occurs mostly in mood disorder and schizophrenic patients, and is related to neuronal dysfunction involving the frontal lobe. Some cases of frontotemporal dementia (FTD) with catatonia have been reported, but these cases were not examined by autopsy. Here, we report on a FTD case which showed catatonia after the first episode of brief psychotic disorder...

Catatonia is a neuropsychiatric condition characterized by physical presentations ranging from profound immobility to excessive motor activity. Emotional aspects of catatonia vary clinically between psychomotor retardation and extreme excitability. In the past, catatonia was considered to be a variant of schizophrenia. However, the disorder actually occurs as a clinical expression of many different psychiatric, neurologic, or medical diagnoses. A prompt diagnostic evaluation should identify any underlying diseases with consideration of somatic pathologies, especially those affecting central nervous system function...

OBJECTIVE: Anti-N-methyl-D-aspartate receptor (NMDAR) antibody was thought to be the cause of anti-NMDAR encephalitis, with manifestations similar to catatonia and schizophrenia. Anti-NMDAR antibody in neuropsychiatric patients who had catatonia before were investigated in a follow-up evaluation. The intensity of antibody immunofluorescence was quantified and compared with healthy controls. METHOD: Nineteen patients (eight males and eleven females) agreed to be followed-up...

This is a case report of a man in his 60s who presented to an English hospital following a significant lithium overdose. He was monitored for 24 hours, and then renal replacement therapy was initiated after assessment by the renal team. As soon as the lithium level returned to normal therapeutic levels (from 4.7 mEq/L to 0.67 mEq/L), lithium was restarted by the medical team. At this point, the patient developed new slurred speech and later catatonia. In this case report, we discuss the factors that could determine which patients are at risk of neurotoxicity following lithium overdose and the appropriate decision regarding when and how to consider initiation of renal replacement therapy and restarting of lithium...
