A case series T and brief literature review ⁎ Sucharita Ananda, Vimal Kumar Paliwala, , Laxmi S Singha, Ravi Uniyalb a Department of Neurology, SGPGIMS, Raebareli road, Lucknow, UP, India b Department of Neurology, King George Medical University, Lucknow, UP, India ARTICLE INFO ABSTRACT Keywords: Catatonia is a well-described clinical syndrome characterized by features that range from mutism, negativism Catatonia and stupor to agitation, mannerisms and stereotype. Causes of catatonia may range from organic brain disorders Extrapyramidal disorder to psychiatric conditions. Despite a characteristic syndrome, catatonia is grossly under diagnosed. The reason for Parkinsonism missed diagnosis of catatonia in neurology setting is not clear. Poor awareness is an unlikely cause because Major depression catatonia is taught among conditions with deregulated consciousness like vegetative state, locked-in state and Schizophrenia akinetic mutism. We determined the proportion of catatonia patients correctly identified by neurology residents in neurology emergency. We also looked at the alternate diagnosis they received to identify catatonia mimics. Twelve patients (age 22–55 years, 7 females) of catatonia were discharged from a single unit of neurology department from 2007 to 2017. In the emergency department, neurology residents diagnosed none of the pa- tients as catatonia. They offered diagnosis of extrapyramidal syndrome in 7, meningitis in 2, and conversion reaction, acute psychosis/encephalopathy and non-convulsive status epilepticus in one each. Their final diag- nosis at discharge was catatonia due to general medical condition in 6 (progressive supranuclear palsy in 2, post- status epilepticus, uremic encephalopathy, glioblastoma multiforme and tuberculous meningitis in one each), catatonia due to major depression in 4, schizophrenia and idiopathic catatonia in one each. Extrapyramidal syndrome appeared as common mimic of catatonia. The literature reviewed also revealed the majority of organic catatonia secondary to causes that are usually associated with extrapyramidal features. Therefore, we suggest that neurologists should consider catatonia in patients presenting with extrapyramidal syndromes. 1. Introduction not specified” [1,6]. The causes of catatonia are a myriad ranging from pure psychiatric illnesses to neurological diseases like encephalitis and Catatonia is a mysterious disorder that is characterized by at least neurodegenerative conditions.

Methods We collected the details of the catatonia patients that were dis- charged from a single unit of the department of Neurology from 2007 to 2017. The case files of the patients were evaluated for their presenting clinical features, examination findings, initial diagnosis made by the neurology residents, investigations, catatonia days, hospitalization days and the final diagnosis at the time of discharge. Based on the presenting clinical features, all patients were subjected to the DSM V criteria for catatonia. Patients fulfilling the DSM V criteria for diagnosis ofcata- tonia were included in the study. The patients were also subjected to the DSM IV criteria and Bush Francis Catatonia Rating Scale (BFCRS) [6,8,9]. Catatonia was classified as: Etiology Major depressive disorder recurrent Catatonia due to GMC Major depressive disorder recurrent Catatonia due to schizophrenia Catatonia due to GMC (PSP) Catatonia due to GMC (PSP) Major depressive disorder recurrent Catatonia related to GMC (bi-fronatalepilepsy, gliosis, SE) Catatonia due to GMC (Glioblastoma multiforme frontal lobe) Catatonia due to GMC (TBMparadoxical with reaction) tuberculoma? Major depressive disorder recurrent Operated case of Schwannoma Catatoniaotherwise not specified 1 Malignant catatonia - characterized by presence of hyperthermia, fever and features of neuroleptic malignant syndrome 2 Periodic type which can be either hyperkinetic or hypokinetic [10]. 3.

All twelve patients also fulfilled DSM IV criteria and BFCRS. Seven patients were females. Age of the patients ranged from 22 to 55 years. Duration of catatonic symptoms was less than 5 days in 4 patients and 5 to 15 days in 7 patients and 1 month in 1 patient. The clinical details of the patients are given in Table 1. The frequencies of different clinical features of catatonia inde- creasing order were waxy flexibility, mutism, negativism, catalepsy, stereotypies, agitation and echolalia. None of our patient had stupor, mannerisms, posturing, grimacing and echo-praxia. Initial diagnosis that was offered to patients after their first clinical examination in the emergency department was extrapyramidal syn- drome (seven patients). Two patients were diagnosed with meningitis, and one each was diagnosed as acute psychosis/encephalopathy, con- version reaction and non-convulsive status epilepticus. The neurology residents diagnosed none of the patient with catatonia or with any brain metastasis of tumor/Metastasis primary psychiatric condition.

There has been a tendency to consider catatonia as a psychiatric disease despite many case reports demonstrating a wide range of medical and neurological as well as psychiatric causes. We present our accumulated experience of the catatonic syndrome. Most cases (36%) were associated with affective illness but five cases (20%) had a defined organic disorder. A significant minority had no identifiable cause and there was only one case of schizophrenia. The idiopathic and affective groups had a high incidence of recurrent catatonic episodes and many had a family history of a similar problem. The prognosis was excellent, except for the few patients who presented with the acute and rapidly progressive form of the syndrome which led to acute renal failure. Karl Ludwig Kahlbaum first described catatonia Case reports during a lecture in Innsbruck in 1868 and published his work on the subject 6 years later in a small A total of 25 cases of catatonia have been seen by the Protected by copyright. monograph entitled "Die Katatonie oder das Department of Neurology at Middlesbrough General Hos- that catatonia is pital during the period 1972 to 1984.

  • Steroid-Responsive Encephalitis Lethargica Syndrome with Malignant Catatonia
    □ CASE REPORT □ Steroid-Responsive Encephalitis Lethargica Syndrome with Malignant Catatonia Yoichi Ono 1, Yasuhiro Manabe 1, Yoshiyuki Hamakawa 1, Nobuhiko Omori 1 and Koji Abe 2 Abstract We report a 47-year-old man who is considered to have sporadic encephalitis lethargica (EL). He presented with hyperpyrexia, lethargy, akinetic mutism, and posture of decorticate rigidity following coma and respira- tory failure. Intravenous methylprednisolone pulse therapy improved his condition rapidly and remarkably. Electroencephalography (EEG) showed severe diffuse slow waves of bilateral frontal dominancy, and paral- leled the clinical course. Our patient fulfilled the diagnostic criteria for malignant catatonia, so we diagnosed secondary malignant catatonia due to EL syndrome. The effect of corticosteroid treatment remains controver- sial in encephalitis; however, some EL syndrome patients exhibit an excellent response to corticosteroid treat- ment. Therefore, EL syndrome may be secondary to autoimmunity against deep grey matter. It is important to distinguish secondary catatonia due to general medical conditions from psychiatric catatonia and to choose a treatment suitable for the medical condition. Key words: encephalitis lethargica, catatonia, steroid therapy (DOI: 10.2169/internalmedicine.46.6179) Introduction Case Report Encephalitis lethargica (EL), named by von Economo, is A 47-year-old man, who had a past history of delusional severe encephalitis which appeared in epidemic form in disorder for about 2 years, developed a pyrexia, vomiting Europe and elsewhere towards the end of World War I and and diarrhea.

  • Cannabis-Induced Catatonia: a Case Series

Psychiatry, Griffin Memorial Hospital, Norman, USA 2. Psychiatry, Medical University of the Americas, Camps, KNA Corresponding author: Kaushal Shah, [email protected] Abstract Catatonia is a psychomotor condition characterized by physical presentations ranging from severe immobility to excessive psychomotor agitation with an array of accompanying emotional aspects. Though initially thought to be a subform of schizophrenia, it is now recognized to be associated with many different psychiatric, neurological, and medical diagnoses. The emergence of catatonia is becoming more prevalent with its changing pattern and extensive use of recreational and illegal drugs. With the legalization of marijuana, its use is on the rise leading to several mental health conditions, including catatonia. If left untreated, catatonia has a significant morbidity and mortality rate; hence, prompt evaluation and diagnosis are critical for the prevention of adverse events. Benzodiazepines (BZDs) and electroconvulsive therapy (ECT) have been found to be most effective and remained as the preferred treatment options. In this paper, we present the case of two patients who presented with catatonia after cannabis consumption and discuss their treatment course and management. Categories: Emergency Medicine, Neurology, Psychiatry Keywords: synthetic cannabis, k2, cannabis, catatonia, addiction, thc, schizophrenia, benzodiazepine, ect, psychiatry Introduction Catatonia is a common condition observed in acutely ill patients with mental health conditions. In the United States, approximately 90,000 people tend to suffer from catatonia each year, with a prevalence ranging between 7.6% to 38% [1].

Summary The locked-in syndrome (LIS) is a state of an upper motor neurone quadriplegia involving the cranial nerve pairs with usually a lateral gaze palsy, paralytic mutism, full consciousness and awareness by the patient of his environment. A his­ torical presentation of the LIS is given as well as a short description of the clinicoana­ tomic lesion causing LIS. The usual cause is vascular and corresponds to a pontine infarction due to an obstruction of the basilar artery but other lesions in the brain­ stem can also be the cause. Non-vascular aetiologies, especially traumatic, are reviewed. The use of electroencephalography (EEG), brain auditory evoked poten­ tials (BAEP) and somesthesic evoked potentials (SEP) are discussed as well as the use in the acute stage of computed tomography (CT), angiography, and magnetic resonance imagery (MR/). The last method may show well delineated ischaemic lesions some time after the event. The communication disability is probably the most difficult to overcome. Two cases of LIS are presented. Key words: Tetraplegia; Locked-in Syndrome; Pontine Infarction; Communica­ tion Disability. The locked-in syndrome (LIS), a term which has been finally adopted since the publication by Plum and Posner in 1966, was, in fact, described more than 100 years ago, by Alexandre Dumas (father) who depicted in 1846 quite accur­ ately in his novel'T he Count of Monte Cristo', Monsieur Noirtier as a'corpse with living eyes'.

Internal Medicine, American University of the Caribbean School of Medicine, Cupecoy, SXM 2. Internal Medicine, Ascension Providence Hospital, Southfield, USA 3. Neurology, Ascension Providence Hospital, Southfield, USA Corresponding author: Mario Dervishi, [email protected] Abstract Creutzfeldt-Jakob disease (CJD) is a rare, rapid and fatal human prion disease that causes neurodegeneration. Rapidly progressive dementia, quick involuntary muscle jerking and specific radiographic and laboratory findings are characteristic of the disease. CJD should not be ruled even if the clinical presentation is outside the common age range. Herein we present a case of an 80-year-old man with probable diagnosis of CJD. The absolute diagnosis of CJD can only be confirmed post-mortem with a brain biopsy. Categories: Internal Medicine, Neurology Keywords: creutzfeldt-jakob disease, prion diseases, neurodegenerative disorders Introduction Prion diseases are a cluster of neurodegenerative pathologies caused by misfolding of proteins called prion [1]. Creutzfeldt-Jakob disease (CJD) is the most common form and accounts for more than 90% of human prion diseases, although it is still rare with 350 cases per year reported in the United States [2]. This disease typically presents with rapid course of symptomatology and the unfortunate, inevitable fate is death. Amongst subtypes (sporadic, familial, iatrogenic and variant), sporadic CJD is the most common form seen in 85%-90% of cases. Disease most commonly affects people of ages 50-70 years, with both genders equally affected [3].

Bharadwaj in chronic psychosis: Department of Psychiatry, Jawaharlal Institute of Postgraduate Medical Education & is chronic catatonia under-recognised? Research, Puducherry, India A case series Introduction Catatonia is a complex syndrome of specific motor abnormalities associ- ated with various psychiatric disorders. Historically, more than 50 clinical signs have been described in catatonia, however, it is now confined to the 23 signs mentioned in the Bush-Francis Catatonia Rating Scale 1. In clinical practice we are apt to recognise catatonia in its stuporous form presenting in emergency with risks due to compromised food and water intake and immobility. Excited catatonia is often missed or diagnosed in hindsight when it presents with manic excitement 2. In this case series we want to highlight that the presence of a few catatonic signs may often be missed as has been pointed out earlier 3. This under-recognition may account for the discrepancy between findings in literature 4. In the Inter- national Pilot Study of Schizophrenia (IPSS) though catatonic signs were noted in 96 patients only a few among them were diagnosed as catatonic schizophrenia. Conversely, most of the 55 patients diagnosed as having catatonic schizophrenia did not have catatonic symptoms 5. In this case series, we would like to present three patients with persistent catatonic symptoms occurring during their psychotic illnesses. The cata- tonic signs were recognized on clinical evaluation. The signs specifically re- sponded to treatment with lorazepam and in two of the cases, drug default or attempts to taper the dose; led to resurgence of catatonic symptoms.

Objective: The aim of this study was to investigate frequency of symptoms of catatonia and the newly diagnosed subclinical inflammatory markers which are neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), monocyte/lymphocyte (MLR) ratios in catatonia patients due to mental disorders. Methods: Patients who were admitted to psychiatry clinic with the diagnosis of catatonia according to DSM 5 in the last two years and equal number of control group were included in this retrospective study. Univariate analysis of covariance controlled for possible confounders was used to compare NLR, PLR, MLR ratios between patients and the control group. Results: A total of 34 catatonia patients and 34 healthy controls were included in the study. Patients’ mean age was 30.88 + 13.4. NLR value was significantly higher in the patient group than control group. There was no significant difference between the patients and control group according to PLR, MLR values.Discussion: The presence of subclinical inflammation in catatonic syndrome due to mental disorders should be considered.
