Touch-screen automatisms in the digital age.

OBJECTIVE: To describe a novel set of gestural automatisms related to the use of digital screens on smartphones and tablets in patients with epilepsy. METHODS: Representative patients were selected from among those admitted to the Epilepsy Monitoring Unit at the Toronto Western Hospital between April 2016 and January 2020, and included if they exhibited automatisms clearly related to or mimicking digital device use. RESULTS: In total 5 patients were included, 4 female. All had temporal lobe epilepsy: 2 had left mesial temporal sclerosis and 3 had normal imaging. Nearly equal numbers of seizures began with right (5/9) and left (4/9) temporal onsets, with most automatisms occurring after seizure propagation to bilateral temporal involvement (6/9). Left-handed automatisms were most common (8/9). The majority of the automatisms (7/9) were perseverative on device usage prior to the seizure. CONCLUSION: Gestural automatisms appear related to the contemporary lived experience, culture, and habitual behaviour of patients with epilepsy. In the modern era, the use of smartphones and tablets are both common and habitual for many, and this case series shows that touch-screen automatisms may be added to the semiological panoply of temporal lobe seizures.

Ictal religious speech in non-dominant temporal lobe epilepsy: three cases.

Ictal religious speech and gestures, rare ictal semiological findings, sign the epileptic focus at the non-dominant temporal lobe in the literature. Therefore, we aim to present non-dominant temporal lobe semiological findings, including ictal praying and religious gestures in three cases.

An International Comparison and Review of Self-Induced Intoxication Causing Automatism.

The topic of self-induced intoxication causing automatism is a complex legal question that straddles the border of psychiatry, the law, and social policy. It has been argued that women and children are predominantly positioned as victims of sexual and domestic violence, in which substances often play a part. This consideration sensitizes society to any legal measures that may potentially excuse, mitigate, or absolve perpetrators. The legal systems in Canada, the United States, and the United Kingdom have dealt with these situations as best as they can, sometimes inconsistently and sometimes coming into conflict with the public discourse and subsequent legislation. This article presents a comparison of case law and legislation among these three countries. We review the concept of automatism and self-induced intoxication leading to automatism, and we show how the courts have dealt with this subject.

Trastorno de la marcha del nivel superior como forma de presentación de una parálisis supranuclear progresiva: descripción de un vídeo caso / Higher-level gait disorder as a presenting manifestation of progressive supranuclear palsy: a video case report

Introducción: El trastorno de la marcha frontal/apraxia de la marcha es un déficit motor del nivel superior con diversas causas, caracterizado por dificultades en el inicio de la marcha (congelación). Nuestro objetivo es presentar una paciente con un trastorno de la marcha del nivel superior con episodios de caídas como manifestaciones iniciales de una parálisis supranuclear progresiva (PSP). Sus datos se obtuvieron de los registros médicos del Servicio de Medicina General del Burdwan Medical College & Hospital (Burdwan, Bengala Occidental, India). Caso clínico: Mujer de 58 años sana que consultó por un trastorno de la marcha con caídas. La exploración neurológica mostró una apariencia facial característica (mirada fija, ojos muy abiertos, ceño fruncido y expresión fija hemifacial inferior), e hipocinesia-rigidez simétrica de predominio axial (postura retrocólica del tronco y el cuello). La exploración de la marcha reveló un trastorno de la marcha del nivel superior, caracterizado por una significativa vacilación inicial, que precisaba ayuda de objetos/personas cercanos. Al iniciar la marcha, los pasos mejoraban relativamente, pero reaparecía una deambulación inefectiva al girar. Presentaba zancadas cortas, congelación, base amplia de sustentación, desequilibrio, movimiento lento de las piernas, arrastre de los pies, y pérdida de la cadencia normal del tronco y las extremidades. Los reflejos posturales estaban alterados. La resonancia magnética cerebral desveló atrofia mesencefálica, dilatación de acueducto de Silvio y III ventrículo, atrofia frontal bilateral y el signo típico del colibrí. Finalmente, la paciente fue diagnosticada de una PSP probable. Conclusiones: Varias etiologías, incluida la PSP, deben considerarse, en el contexto clínico apropiado, si la exploración de la deambulación demuestra un trastorno de la marcha del nivel superior.(AU)

Introduction: In the evaluation of drug-resistant epilepsy, a detailed analysis of the semiology is essential to establish a diagnostic hypothesis of the location of the epileptogenic zone. Cross-sign (CS) is a very infrequent complex manual automatism described for the first time in 2008 and rarely reported in the literature. Case report: We present two cases from our series of patients monitored by video-EEG, one of whom also studied with deep electrodes, in which we describe the location of the discharge while performing the CS. A bibliographic review is also carried out to try to establish a localizing and/or lateralizing value of this sign. Conclusion: The sign of the cross is a rare ictal automatism that occurs in patients with temporal lobe epilepsy. The hand used to make the sign of the cross is the dominant one, regardless of the origin of the crises.(AU)

La señal de la cruz: un automatismo muy poco frecuente en la epilepsia del lóbulo temporal. Descripción de dos casos / The sign of the cross: a very rare automatism in temporal lobe epilepsy. Two case reports

Introducción: En la evaluación de la epilepsia farmacorresistente, el análisis detallado de la semiología es fundamental para establecer una hipótesis diagnóstica de la localización de la zona epileptógena. La señal de la cruz es un automatismo manual complejo muy infrecuente descrito por primera vez en 2008 y poco referido en la bibliografía. Caso clínico: Presentamos dos casos con presencia de la señal de la cruz de nuestra serie de pacientes monitorizados mediante videoelectroencefalograma, uno de ellos estudiado también con electrodos profundos, en los que describimos la localización de la descarga en el momento de realizar la señal de la cruz. Se realiza también una revisión bibliográfica para intentar establecer un valor localizador y/o lateralizador de este signo.(AU)

[Bimodal model of delusional psychoses (on the problem of the correlation of paranoid dimensions in the psychopathological space of schizophrenia)]. / Bimodal'naya model' bredovykh psikhozov (k probleme sootnosheniya paranoidnykh dimensii v psikhopatologicheskom prostranstve shizofrenii).

OBJECTIVE: To establish clinico-pathogenetic ratios of delusional psychoses constituting the psychopathological space of paranoid schizophrenia and to determine clinical and pathogenetic validity of concepts of a single delusional psychosis (a model of chronic delusion with a staged course) and two endogenous delusional psychoses. MATERIAL AND METHODS: A sample consisted of 56 patients (19 women, 37 men; the average age 39.7±9.3 years; average duration of the disease 10.6±9.1 years) with a diagnosis of paranoid schizophrenia, continuous type of course (F20.00), developed at the age above 18 years. At the time of examination, the condition of the patients was determined by persistent delusional or hallucinatory delusional disorders. Clinical, pathopsychological, psychometric (SANS, SAPS, PANSS), immunological and statistical methods were used. RESULTS: The study substantiates a bimodal model of a single delusional psychosis with a polar arrangement of interpretive delusions and delusions of influence based on the phenomena of mental automatism, both in terms of the vector of development (toward the poles of negative/positive disorders) and in terms of the rate of progression. Psychopathological manifestations of interpretive delusions correlate with the slow evolving development of psychosis, the dimensional structure of the paranoid is limited to the limits of the delusional register; functional activity is represented by affiliation to negative changes, integration with personality anomalies ends with the transformation of positive disorders into pathocharacterological ones, corresponding to the post-processual development of the personality. Manifestation of delusional impact (syndrome of mental automatism) is manifested by the complication and maximum expansion of the spectrum of positive disorders; the dimensional structure is represented by a wide range of psychopathological disorders and is formed with the participation of processes of mental dissociation, reaching the level of delusional depersonalization; functional activity is high, which creates conditions for the formation of a «new¼ subpsychotic structure, a «psychotic character¼, which is an attenuated duplicate of delusional psychosis. In both groups of patients, a significant increase in the activity of inflammatory markers of leukocyte elastase (249.2 ((231.1-270.0); 272.2 (236.0-292.6) nmol/min∙ml) and alpha - 1 proteinase inhibitor (48.8 (46.0-55.0); 50.4 (42.1-54.8) IU/ml) was shown compared with controls (205.0 (199.8-217.3) nmol/min∙mL and 33.0 (31.0-36.0) IU/mL, p<0.01, respectively). In the group of patients with delusions of influence, an increased level of antibodies to S-100B was also observed (0.88 (0.67-1.0) opt.density units) compared with the control values (0.7 (0.65-0.77) opt.density units, p<0.05). CONCLUSION: The concept of the model is supported by the results of the immunological study, according to which interpretive delusions and delusion based on the mental automatism, indicates the different level of immunity tension, and a qualitative changes in immune reactivity (also due to different genetic burden).

Development of an Automatic Pill Image Data Generation System.

OBJECTIVES: Since the easiest way to identify pills and obtain information about them is to distinguish them visually, many studies on image processing technology exist. However, no automatic system for generating pill image data has yet been developed. Therefore, we propose a system for automatically generating image data by taking pictures of pills from various angles. This system is referred to as the pill filming system in this paper. METHODS: We designed the pill filming system to have three components: structure, controller, and a graphical user interface (GUI). This system was manufactured with black polylactic acid using a 3D printer for lightweight and easy manufacturing. The mainboard controls data storage, and the entire process is managed through the GUI. After one reciprocating movement of the seesaw, the web camera at the top shoots the target pill on the stage. This image is then saved in a specific directory on the mainboard. RESULTS: The pill filming system completes its workflow after generating 300 pill images. The total time to collect data per pill takes 21 minutes and 25 seconds. The generated image size is 1280 × 960 pixels, the horizontal and vertical resolutions are both 96 DPI (dot per inch), and the file extension is .jpg. CONCLUSIONS: This paper proposes a system that can automatically generate pill image data from various angles. The pill observation data from various angles include many cases. In addition, the data collected in the same controlled environment have a uniform background, making it easy to process the images. Large quantities of high-quality data from the pill filming system can contribute to various studies using pill images.

Can we tackle climate change by behavioral hacking of the dopaminergic system?

Climate change is an undeniable fact that will certainly affect millions of people in the following decades. Despite this danger threatening our economies, wellbeing and our lives in general, there is a lack of immediate response at both the institutional and individual level. How can it be that the human brain cannot interpret this threat and act against it to avoid the immense negative consequences that may ensue? Here we argue that this paradox could be explained by the fact that some key brain mechanisms are potentially poorly tuned to take action against a threat that would take full effect only in the long-term. We present neuro-behavioral evidence in favor of this proposal and discuss the role of the dopaminergic (DA) system in learning accurate prediction of the value of an outcome, and its consequences regarding the climate issue. We discuss how this system discounts the value of delayed outcomes and, consequently, does not favor action against the climate crisis. Finally, according to this framework, we suggest that this view may be reconsidered and, on the contrary, that the DA reinforcement learning system could be a powerful ally if adapted to short-term incentives which promote climate-friendly behaviors. Additionally, the DA system interacts with multiple brain systems, in particular those related to higher cognitive functions, which can adjust its functions depending on psychological, social, or other complex contextual information. Thus, we propose several generic action plans that could help to hack these neuro-behavioral processes to promote climate-friendly actions.

Seizures, Postictal States and Criminal Responsibility.

This column provides an overview of how courts have taken into account seizures and postictal states in terms of assigning criminal responsibility. In England, New Zealand and Australia, courts have generally treated evidence of epileptic seizures and postictal states as raising the defence of mental impairment which often results in indefinite detention. In comparison, there is a series of Canadian cases that have resulted in acquittals after evidence of seizures has been accepted as negating voluntariness or the fault element of the offence. It appears that policy issues have been influential in the Canadian cases, particularly a reluctance to equate epilepsy with "mental disorder".

The Ontario Court of Appeal Takes a New Look at Automatism in R v. Sullivan.

Automatism has long been a significant topic of discussion between forensic psychiatry and the courts. In a recent case, the Ontario Court of Appeal addressed this concept in the setting of a Canadian law, s. 33.1 of the Criminal Code, that limits the defense of self-induced intoxication for any offense involving violence. The court found that s. 33.1 violated the presumption of innocence and the principles of fundamental justice and could not be saved by the Canadian Charter of Rights and Freedoms, as it was not demonstrably justifiable in a free and democratic society. Therefore, the court declared s. 33.1 to be of no force and effect. In this article, we describe the legal history of automatism in Canadian courts and the reasoning behind this important decision. Finally, we discuss some implications for forensic practice.

Metabolic phenotyping of hand automatisms in mesial temporal lobe epilepsy.

PURPOSE: Hand automatisms (HA) are common clinical manifestations in mesial temporal lobe epilepsy. However, the location of the symptomatogenic zone (EZ) in HA as well as the networks involved, are still unclear. To have a better understanding of HA underlying mechanisms, we analyzed images from interictal [18F] fluorodeoxyglucose-positron emission tomography (FDG-PET) in patients with mesial temporal lobe epilepsy (mTLE). METHODS: We retrospectively recruited 79 mTLE patients and 18 healthy people that substituted the control group for the analysis. All patients underwent anterior temporal lobectomy and were seizure-free. Based on the semiology of the HA occurrence, the patients were divided into three subgroups: patients with unilateral HA (Uni-HA), with bilateral HA (Bil-HA) and without HA (None-HA). We performed the intergroup comparison analysis of the interictal FDG-PET images and compared the functional connectivity within metabolic communities. RESULTS: Our analysis showed that the metabolic patterns varied among the different groups. The Uni-HA subgroup had significant differences in the extratemporal lobe brain areas, mostly in the ipsilateral supplementary motor area (SMA) and middle cingulate cortex (MCC) when compared to the healthy control group. The Bil-HA subgroup demonstrated that the bilateral SMA and MCC areas were differentially affected, whereas in the None-HA subgroup the differences were evident in limited brain areas. The metabolic network involving HA showed a constrained network embedding the SMA and MCC brain regions. Furthermore, the increased metabolic synchronization between SMA and MCC was significantly correlated with HA. CONCLUSION: The metabolic pattern of HA was most conspicuous in SMA and MCC brain regions. Increased metabolic synchronization within SMA and MCC was considered as the major EZ of HA.

The higher the score, the better the clinical outcome: retrospective evaluation of automatic embryo grading as a support tool for embryo selection in IVF laboratories.

STUDY QUESTION: Is the automatic embryo grading function of specific time-lapse systems clinically useful as a decision support tool for IVF laboratories? SUMMARY ANSWER: Blastocyst grading according to the automatic scoring system is directly associated with the likelihood of implantation and live birth, at least in treatments without preimplantation genetic testing for aneuploidy (PGT-A). WHAT IS KNOWN ALREADY: Several embryo selection algorithms have been described since the introduction of time-lapse technology in IVF laboratories, but no one algorithm has yet been sufficiently consolidated for universal use. Multicentric models based on automated grading systems offer promise for standardization of embryo selection. STUDY DESIGN, SIZE, DURATION: A retrospective cohort study was performed including 1678 patients who underwent IVF treatments between 2018 and 2020 and whose embryos (n = 12 468) were cultured in time-lapse systems. PARTICIPANTS/MATERIALS, SETTING, METHODS: After obtaining the required parameters (division time to 2, 3, 4 and 5 cells; time of blastocyst formation; inner cell mass quality; and trophectoderm quality), the automatic embryo score was calculated using the software included in the appropriate workstation. First, embryo score was compared with conventional morphological quality and the subsequent clinical outcomes of 1952 single blastocyst transfers. Second, we quantified the contribution of the automatic embryo score and conventional morphological grade to implantation and live birth outcome with multivariate logistic regression analysis in different patient populations. MAIN RESULTS AND THE ROLE OF CHANCE: A higher embryo score was associated with a better clinical outcome of IVF treatment. The mean of the automatic embryo score varied significantly (P < 0.001) among embryos with different morphological categories, between euploid and aneuploid embryos, between embryos resulting in positive versus negative pregnancy, between implanted and non-implanted embryos, and between embryos resulting in positive and negative live birth. Embryo score was related to the odds of implantation and live birth in the oocyte donation program (odds ratio (OR)=1.29; 95% CI [1.19-1.39]; P < 0.001 for implantation and OR = 1.26; 95% CI [1.16-1.36]; P < 0.001 for live birth) and in conventional treatments with autologous oocytes (OR = 1.38; 95% CI [1.24-1.54]; P < 0.001 for implantation and OR = 1.47; 95% CI [1.30-1.65]; P < 0.001 for live birth). There was no significant association of embryo score with implantation or live birth in treatments involving PGT-A. LIMITATIONS, REASONS FOR CAUTION: This study is limited by its retrospective nature. Further prospective randomized trials are required to confirm the clinical impact of these findings. The single-center design should be taken into account when considering the universal application of the model. WIDER IMPLICATIONS OF THE FINDINGS: Evidence of the clinical efficiency of automated embryo scoring for ranking embryos with different morphological grade and potential in order to achieve higher implantation and live birth rates may make it a decision support tool for embryologists when selecting blastocysts for embryo transfer.

Oral and manual automatisms elicited by electrical stimulation of the pars opercularis cortex in a patient with frontal lobe epilepsy.

Oral automatism (OA) and manual automatism (MA) are common signs during initiation of temporal seizures. However, the precise symptomatogenic zones for OA and MA remains largely unclear. In this study, we presented a case of intractable frontal lobe epilepsy (FLE) in which the patient received intracranial EEG monitoring with subdural electrodes. During electrical stimulation of a grid contact located over the right pars opercularis cortex, OA and contralateral MA were observed unexpectedly without afterdischarges (ADs) or with brief ADs detected in the adjacent contacts. This case suggested that the pars opercularis cortex might play an important role in generating OA. In addition, our data implied that the symptomatogenic zone for MA might locate contralaterally to symptomatic hand.

Temporal lobe epilepsy: A never-ending story.

INTRODUCTION: Semiology and anatomo-electroclinical correlations remain invaluable for maintaining the level of excellence in temporal lobe epilepsy (TLE) surgery, in parallel to the constantly evolving technical progress. The aim of this study was to address semiological frequent and not so frequent signs, rarities and red flags in a long follow-up surgical series of patients suffering from TLE. METHODS: Patients operated within the boundaries of the TL at our center, with presurgical video-EEG recorded seizures and seizure free after a postoperative follow-up of at least 24 months were included. Ictal semiology was systematically described and new red flags were explored by comparing with a second group of patients with the same inclusion criteria but whose outcome had been unfavorable (Engel II-IV). RESULTS: Sixty-two patients were included, 46 seizure free and 16 with outcome Engel II-IV. Most seizure-free patients had a classical semiological presentation including aura (69.6%, abdominal the most frequent), followed by loss of responsiveness (90.2%) oral automatisms (90.7%), ipsilateral gestural automatisms (53.5%), contralateral upper limb dystonia (37.5%) or immobility (39.1%), and early ipsilateral non-versive head orientation (33.3%). More infrequent presentations were also present in the group of seizure-free patients: ictal language disturbance (13%), maintenance of responsiveness during seizures (9.8%), and contralateral rhythmic non manipulative automatism (6.9%). The presence of an isolated viscerosensory and/or psychic aura was significantly more frequent in the seizure-free group (p = 0.017), as well as oroalimentary automatisms (p = 0.005). Two signs were only present in the group with outcome Engel II-IV, constituting possible red flags (0.06 < p < 0.07): inferior limbs stepping-like automatisms and postictal dysarthria. CONCLUSION: An adequate clinical exam during seizures and a careful analysis of video recordings allow to recognize infrequent but well-characterized ictal signs that are part of the range of semiology in TLE, together with the most frequent and classical ictal presentations. Special attention to the localization hypothesis must be paid in the absence of oroalimentary automatisms or when the signs classified as possible red flags emerge.

Neuropsychological spectrum in early PD: Insights from controlled and automatic behavioural regulation.

Initial changes in Parkinson's disease (PD) are marked by loss of automatic movements and decline of some cognitive functions. Yet, the exact profile and extent of cognitive impairments in early stages of PD as well as their mechanisms related to automatic motor dysfunction remain unclear. Our objective was to examine the neuropsychological changes in early PD and their association to automatic and controlled modes of behavioural control. Significant relationships between early PD and cognitive dysfunction in set-shifting, abstraction ability/concept formation, processing speed, visuospatial/constructional abilities and verbal-visual memory was found. We also noted that tests with a strong effortful and controlled component were similarly affected as automatic tests by early PD, particularly those testing verbal memory, processing speed and visuospatial/constructional functions. Our findings indicate that initial stages of PD sets constraints over most of the cognitive domains normally assessed and are not easily explained in terms of either automatic or controlled mechanisms, as both appear similarly altered in early PD.

The Strategy of Evaluation Automatism for Disability Assessment: A Pragmatic Choice to Simplify the Decision-making Process in the Italian Welfare System.

The first instance assessment of all disability sectors in Italy takes place in most parts of the country in two stages. The first step is the applicant's examination and judgment performed by the Local Health Authority (ASL). The second phase is the verification of the National Social Security Institute (INPS) on the ASL report, which ends with its confirmation or suspension and repetition. Disability examination strategies can fluctuate between the evaluation automatism and the personalised approach. Evaluation automatism implies a necessary and shared prediction of the judgment due to a specific diagnosis. The personalised approach favours a rigorously individualised, unrepeatable assessment, specifically adapted to the case examined. In both perspectives, the criteria for defining disability belong to a medical model that measures the disease-related impairment. The degree of sharing of judgments between ASL and INPS can often imply and express the contribution of the evaluation automatism to the procedure.

Case Report: Not All Neurological Symptoms Respond Well to Penicillin in Patients With Neurosyphilis.

Patients with neurosyphilis present with a wide range of neurological symptoms, the response of which to penicillin is not well known. In this paper, we analyzed the clinical video-electroencephalogram (EEG) features of neurosyphilis in a 54-year-old man who exhibited with rhythmic orofacial involuntary movements, Argyll Robertson pupil, frequent paroxysmal oral-automatism seizures, periodic lateralized discharges (PLEDs) with triphasic waves, behavioral changes, and memory decline. After treatment with penicillin, PLED and seizures disappeared and behavioral changes and memory decline were significantly improved, but rhythmic orofacial involuntary movements and Argyll Robertson pupil persisted, which indicates an irreversible characteristic of late stage neurosyphilis syndromes.
