Aggression and violence in patients with epilepsy

Ictal Coprolalia: Three Cases with Nondominat Frontal Lobe Involvement and Review of the Literature

Objective: Coprolalia is defined as the involuntary use of obscene, socially unacceptable, and derogatory words. Ictal coprolalia is a rare presentation of epilepsy. This study aimed to determine the localizing and lateralizing value and frequency of ictal coprolalia in epilepsy patients. Methods: Medical files, discharge summaries, and electroencephalography (EEG) reports of 2238 patients were reviewed retrospectively. We identified patients who suffered from ictal coprolalia. Electroencephalography reports, neuroimaging [brain magnetic resonance imaging (MRI), fluorodeoxyglucose positron emission tomography (FDG-PET), single-photon emission computerized tomography (SPECT)] records, F-18 FDG fused on MRI images, and ictal SPECT fused on MRI images were evaluated. Also, original and review articles were identified through a systematic search of Pubmed, Scopus, and Clarivate Analytics. Results: Ictal coprolalia was detected in 3 male (0.15%) patients. In all patients, ictal semiology was extratemporal-frontal type, and potential/proven epileptic focus was non-dominant hemisphere frontal lobe. Topectomy was done in one of the patients, including the suspected dysplastic area plus the area where the electroencephalographic ictal and interictal changes occur, on the left frontal lobe, and the patient had an Engel's classification class IIA. The data depending on the published cases showed that ictal coprolalia was dominant in the male gender and the responsible epileptic area tended to be located in the non-dominant hemisphere frontotemporal region. Conclusion: The rate of ictal coprolalia in the Turkish population is lower compared to other series. Our results are consistent with previous studies in which reported that male preponderance for ictal coprolalia and involvement of non-dominant frontal lobe.

Alcohol use, civilian interference, and other possible risk factors for death during restraint

Physical restraint is usually used when trying to control and terminate a violent episode. Many causes are possible behind aggressive, agitated, and violent behavior. Some of these are such factors that can either be detected in forensic autopsies or can be evident from the person's medical records. Various causes for deaths during physical restraint have been suggested. In this study, we wanted to review all incidents in which physical restraint was employed, ending in death of the restrained person, whether the restraint was applied by police officers, security guards, police custody personnel, health care personnel or ordinary civilians. The main aim was to see if this new kind of study design would increase our knowledge in circumstances and causes leading to death in restraint situations. Data was collected retrospectively from all forensic autopsies performed in the Southern Finland area during 2010-2015. We went through 21,036 forensic autopsy cases and found 12 cases (0.06 %) in which a physical restraint was employed before death. Police officers were involved in the physical restraint in 7/12 of the cases: in two of these cases, police alone; in three cases, police and guards; and in two cases, police and health care personnel. Civilians carried out the restraint in 5/12 cases. With civilians responsible for the restraint, the cause of death was more likely considered to be a result of the restraint itself than in cases where police and other authorities were responsible for the restraint. This could be because civilians aren't educated about safe restraint methods, and they might themselves be intoxicated. Alcohol was the most common psychoactive substance found in this study and could be a risk factor for not only aggressive behavior but also death, since alcohol use can provoke cardiac arrhythmias and even sudden death. Based on this study, and previously published studies, we see restraint deaths as a varying spectrum of deaths, in which the death is often possibly a result of many factors, including the effects of agitation and restraint, intoxication, and cardiac and other illnesses.

Mental health criminal defenses in persons with neuropsychiatric disorders

Persons with neuropsychiatric disorders present specific and unique challenges for forensic experts and defense attorneys in the criminal justice system. This article reviews two potential criminal defenses: legal insanity and the various legal standards or tests of criminal responsibility that are used in jurisdictions throughout the United States (i.e., the M'Naghten standard and the American Law Institute's Model Penal Code), and the partial legal defense of diminished capacity (lacking the mental state necessary to be found guilty of a specific intent crime). The process of evaluating criminal responsibility or diminished capacity is also presented with a specific emphasis on common issues that arise in evaluating defendants with Intellectual Developmental Disorder (Intellectual Disability), Parasomnias, Seizure Disorders, and Neurocognitive Disorders.

Forensic neuropsychiatric aspects of epilepsy

Epilepsy may be associated with automatisms that are classed as 'insane 'as they are deemed to have originated within the mind. 'Sane automatism' is said to occur from external factors, such as physical trauma, while 'insane automatism' is said to be innate to the individual experiencing them. To claim automatism within the context of a criminal matter requires a detailed evaluation of the behavior demonstrated and a questioning of the volitional and purposeful nature of this behavior. It is insufficient to rely upon past behavior in association with these seizures to justify the defense of automatism within a specific event. Epilepsy is often considered to be associated with an increase in violence. Proper epidemiological research, both in long-term, large population control studies and hospital-based studies, has suggested that epilepsy, per se, is not associated with an increase in violence when compared to the population at large and controlled for other familial and environmental factors.

Developmental Regression Followed by Epilepsy and Aggression: A New Syndrome in Autism Spectrum Disorder?

Autism spectrum disorder (ASD) with regression (ASD-R) involves the loss of previously attained developmental milestones, typically during the first or second year of life. As children age, it is not uncommon for them to develop comorbid conditions such as aggressive behaviors or epilepsy, which can inhibit habilitation in language and social function. In this paper, we hypothesize that aggressive behaviors and epilepsy more commonly develop in patients with ASD-R than in those without a history of regression (ASD-NR). We conducted a retrospective review of non-syndromic patients with ASD over 12 years of age and compared the rates of epilepsy and aggression between ASD-R and ASD-NR patients. Patients with ASD-R, as compared to ASD-NR patients, demonstrated non-significantly higher rates of epilepsy (51.8% vs. 38.1%, p = 0.1335) and aggressive behaviors (73.2% vs. 57.1%, p = 0.0673) when evaluated separately. The rates for combined epilepsy and aggression, however, were statistically significant when comparing ASD-R versus ASD patients (44.5% vs. 23.8%, p = 0.0163). These results suggest that epilepsy with aggression is more common in ASD-R as compared to ASD-NR patients. When considering the impact of epilepsy and aggression on quality of life, these co-morbidities effectively cause a second regression in patients who experienced an earlier regression as toddlers. A larger, prospective trial is recommended to confirm these associations and further define the timeline in which these characteristics develop from early childhood to adolescence.

Criminal Liability and Epilepsy: A Case Report of a Postictal Attempted Homicide from Tunisia

INTRODUCTION

Epileptic patients charged with a serious offense may be referred by courts for forensic psychiatric examination, which may pose a legal challenge. Therefore, a detailed examination is necessary to assist the courts in making the right decision.

METHOD

We present the case of a 30-year-old Tunisian male with temporal epilepsy who exhibited an inadequate response to the treatment. The patient attempted to kill his neighbor after a cluster of seizures, showing apparent post-ictal aggression. An anti-epileptic treatment was reintroduced a few days after the detention followed by forensic psychiatric examination three months afterwards.

RESULTS

On the forensic examination, the patient's thought process was clear with no evidence of a thought disorder or a psychosis. Both medical and psychiatric opinions stated that the attempted homicide was due to a post-ictal psychosis. The patient was transferred to a psychiatric facility for further management as he was found not guilty by reason of insanity.Conclusion:This case report illustrates the difficulties that experts may encounter in establishing criminal liability after an aggressive behavior associated with epilepsy. It highlights some shortcomings in theTunisian law that should be addressed to ensure the fairness of the legal process.

Epilepsy, violence, and crime. A historical analysis

In the 19th and early 20th century, epilepsy was one of the most investigated disorders in forensic psychiatry and psychology. The possible subsidiary symptoms of epilepsy (such as temporal confusion, alterations of consciousness, or increased aggression) played pivotal roles in early forensic and criminal psychological theories that aimed to underscore the problematic medical, social and legal status of epileptic criminals. These criminals were considered extremely violent and capable of committing sudden, brutal acts. Although the theory of "epileptic criminality" was refuted due to 20th-century developments in medicine, forensic psychiatry, and criminal psychology, some suppositions related to the concept of epileptic personality have lingered. This paper explores the lasting influence of the theory of epileptic personality by examining the evolution of the theories of epileptic criminality both in the international and the Hungarian context. Specifically, it calls attention to the twentieth-century revival of the theory of epileptic personality in the works of Leopold Szondi, István Benedek and Norman Geschwind. The paper shows that the issue of epileptic personality still lingers in neuropsychology. In doing so, biological reductionist trends in medical-psychological thinking are traced, and attention is drawn to questions that arise due to changing cultural and medical representations.

Criminal victimization of people with epilepsy: Sixteen criminal judgments in Japan between 1990 and 2019

Criminal behavior by people with epilepsy (PWE) has often been discussed. However, there are limited studies on criminal victimization of PWE-in particular, how such victimizations occur. We identified criminal cases involving victims with epilepsy using databases containing criminal judgments and found 16 such cases between 1990 and 2019. Seven were homicide cases, including four filicide cases. In the four filicide cases, all the perpetrators had the intention of homicide-suicide; all the victims had intellectual disabilities or cerebral palsy; two of these victims had acted violently toward the family; and two mothers who perpetrated the crime against the victims had depression. It seemed that the comorbidities and problem behaviors of the victims were more strongly related to serious crimes by family caregivers than the epilepsy itself. To prevent victimization caused by family caregivers, reducing their stress levels is important. Defendants sometimes argued against objective evidence of a crime, claiming that epileptic seizure of PWE caused or was related to the death of victims. Legal and medical professionals involved in determining the manner of death need careful evaluation when sudden deaths of PWE occur.

Emotion and mood disorders associated with epilepsy

Epilepsy is a disorder characterized by recurrent seizures. Epilepsy can alter mood and emotions. Treatments for epilepsy can also alter mood and emotions. This chapter reviews the emotional changes that can occur before, during, and after a seizure, such as fear and anger, the interictal mood disorders associated with epilepsy, such as depression and anxiety, as well as alterations of emotional processing including comprehending and expressing emotional prosody and faces. The possible treatments of these emotional and mood disorders are also reviewed.

Pharmacological Approaches to Managing Violence and Aggression in Prison Populations: Clinical and Ethical Issues

Violence and aggression are common problems encountered in prison, which frequently require clinical intervention. This increased prevalence is partially attributable to the high morbidity of psychiatric and personality disorders in prison inmates. As prisons are non-therapeutic environments, the provision of clinical care becomes more complex. This article examines the general principles of management of violence and aggression in prison settings, with a particular focus on the clinical and ethical considerations that guide pharmacological approaches. Use of psychotropic medication to address these problems is reserved for situations where there is (i) a diagnosable psychiatric disorder, or (ii) a significant risk of harm to an individual without urgent intervention. Initial focus should be on environmental and behavioural de-escalation strategies. Clear assessment for the presence of major mental illness is crucial, with appropriate pharmacological interventions being targeted and time-limited. Optimising management of any underlying psychiatric conditions is an important preventative measure. In the acute setting, rapid tranquilisation should be performed according to local guidelines with a focus on oral prior to parenteral administration. Clinicians must be mindful of capacity and consent issues amongst prisoners to protect patient rights and guide setting of care.

Self-injurious behavior in epilepsy

Self-injurious behavior (SIB) can be described as an act involving self-inflicted destruction of tissue, right away or over a period of time. Patients with epilepsy have to deal with an often chronic and unpredictable disorder leading to adversity in many psychosocial variables such as employment, stigma, and overall quality of life. The above factors contribute toward SIB in these patients. Behavioral problems occurring in people with epilepsy can range from aggressiveness, mood fluctuations to SIB. We report a 23-year-old male, married, educated up to 10^th standard, referred from neurology department for psychiatric evaluation. The patient had gone to neurologist with the chief complaints of generalized tonic-clonic convulsions and was hospitalized for breakthrough seizure. There was a history of indulging in episodes of self-SIB since the past 8 months. He responded satisfactorily to adjustment of antiepileptic medication along with fluoxetine and low-dose risperidone. Early identification of such behavior in epilepsy patients should be done so that a holistic management is undertaken leading to better functioning and improved quality of life.

Epileptic seizures and criminal acts: Is there a relationship?

BACKGROUND

The relation between epilepsy and criminal acts has been debated for over a century. The general perception persists that epileptic seizures can be associated with violent behavior. Some studies have provided evidence for such an association; however, it remains uncertain whether it really exists. This review critically evaluates the scientific literature on the possible relation between epileptic seizures and criminal acts.

METHODS

A PubMed search was undertaken using the search terms "epilepsy and crime", "epilepsy and automatism", "epilepsy and law", and "epilepsy and dyscontrol syndrome" with the aim of identifying studies examining the possible association between epileptic seizure and crime.

RESULTS

The combined keywords "epilepsy and crime" yielded 495 articles, the keywords "epilepsy and automatism" 402 results, the keywords "epilepsy and law" 969 articles, and the keywords "epilepsy and dyscontrol syndrome" resulted in 22 search results. After removing publications such as reviews and opinion pieces, we identified and analyzed a total of 24 research articles with relevant original data. These included single case reports. The reviewed literature suggests that there are very rare occasions when criminal acts are committed during the ictal or postictal period, mostly by patients with focal epilepsy.

CONCLUSION

The literature on the relation between epileptic seizures and criminal acts is not conclusive. Behavioral disturbances often seem more closely related to comorbidities of epilepsy than particular seizures characteristics. These comorbidities are often not well-described. There is an urgent need for more systematic and detailed data gathering and reporting, in order to allow a more detailed investigation of the relation between epileptic seizures and criminal acts.

Mechanisms Underlying Aggressive Behavior Induced by Antiepileptic Drugs: Focus on Topiramate, Levetiracetam, and Perampanel

Antiepileptic drugs (AEDs) are effective against seizures, but their use is often limited by adverse effects, among them psychiatric and behavioral ones including aggressive behavior (AB). Knowledge of the incidence, risk factors, and the underlying mechanisms of AB induced by AEDs may help to facilitate management and reduce the risk of such side effects. The exact incidence of AB as an adverse effect of AEDs is difficult to estimate, but frequencies up to 16% have been reported. Primarily, levetiracetam (LEV), perampanel (PER), and topiramate (TPM), which have diverse mechanisms of action, have been associated with AB. Currently, there is no evidence for a specific pharmacological mechanism solely explaining the increased incidence of AB with LEV, PER, and TPM. Serotonin (5-HT) and GABA, and particularly glutamate (via the AMPA receptor), seem to play key roles. Other mechanisms involve hormones, epigenetics, and “alternative psychosis” and related phenomena. Increased individual susceptibility due to an underlying neurological and/or a mental health disorder may further explain why people with epilepsy are at an increased risk of AB when using AEDs. Remarkably, AB may occur with a delay of weeks or months after start of treatment. Information to patients, relatives, and caregivers, as well as sufficient clinical follow-up, is crucial, and there is a need for further research to understand the complex relationship between AED mechanisms of action and the induction/worsening of AB.

'They accused me of strangling her': epilepsy and violence debate in Croatia at the end of the nineteenth and the beginning of the twentieth centuries

Nineteenth-century psychiatry shifted its focus to the brain as the seat of mental disorders. With a new understanding of mental disorders arose the need to consult forensic psychiatrists in cases of criminal acts committed by persons with mental illness. This article focuses on three murders committed by 'epileptics' at the end of the nineteenth and the beginning of the twentieth centuries in Croatia. An analysis of these cases will help to situate forensic psychiatry at the turn of the century within the Austro-Hungarian Empire, and reveal the authority that forensic experts wielded in the courts. We will argue that Cesare Lombroso's biological theory of crime, as well as the influence of eugenicists and pharmaceutical companies, shaped the long-standing relationship between epilepsy and violent behaviour.

Epilepsy, Antiepileptic Drugs, and Aggression: An Evidence-Based Review

Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

Treatment issues for children with epilepsy transitioning to adult care

This is the third of three papers that summarize the second symposium on Transition in Epilepsies held in Paris in June 2016. This paper focuses on treatment issues that arise during the course of childhood epilepsy and make the process of transition to adult care more complicated. Some AEDs used during childhood, such as stiripentol, vigabatrin, and cannabidiol, are unfamiliar to adult epilepsy specialists. In addition, new drugs are being developed for treatment of specific childhood onset epilepsy syndromes and have no indication yet for adults. The ketogenic diet may be effective during childhood but is difficult to continue in adult care. Regional adult epilepsy diet clinics could be helpful. Polytherapy is common for patients transitioning to adult care. Although these complex AED regimes are difficult, they are often possible to simplify. AEDs used in childhood may need to be reconsidered in adulthood. Rescue medications to stop prolonged seizures and clusters of seizures are in wide home use in children and can be continued in adulthood. Adherence/compliance is notoriously difficult for adolescents, but there are simple clinical approaches that should be helpful. Mental health issues including depression and anxiety are not always diagnosed and treated in children and young adults even though effective treatments are available. Attention deficit hyperactivity disorder and aggressive behavior disorders may interfere with transition and successful adulthood but these can be treated. For the majority, the adult social outcome of children with epilepsy is unsatisfactory with few proven interventions. The interface between pediatric and adult care for children with epilepsy is becoming increasingly complicated with a need for more comprehensive transition programs and adult epileptologists who are knowledgeable about special treatments that benefit this group of patients.

Impact of aggression, depression, and anxiety levels on quality of life in epilepsy patients

The aim of this study was to investigate the impact of aggression levels on the quality of life (QoL) of epilepsy patients. This study was conducted on 66 volunteer control subjects, who were matched by age and sex to the patient group, which consisted of 66 patients who applied to the Psychiatry and Neurology clinics for outpatient treatment, were aged between 18 years and 65 years, and were diagnosed with epilepsy. A sociodemographic and clinical data form designed by us was distributed among the study participants, along with Buss-Perry Aggression Scale, Beck Anxiety Scale, Beck Depression Scale, and the Quality of Life Scale Short Form (SF-36). Compared with the control group, the patient group displayed higher scores in all subgroups of Buss-Perry Aggression Scale subscales at a statistically significant level (P<0.05). As per the SF-36 questionnaire, physical functioning, physical role disability, general health perception, social functioning, mental health perception, and pain subscales were statistically lower in the patient group (P<0.05). Significant links between Beck Depression Scale and Beck Anxiety Scale levels, as well as some subscales of QoL and aggression levels, were also determined. In conclusion, epilepsy patients experienced impaired QoL compared with the healthy control group and their QoL was further impaired due to increased levels of anxiety, depression, and aggression.

Psychiatric presentation of childhood epilepsy: Case series and review

Childhood-onset epilepsy has a varied presentation and may have different etiological factors. A multiaxial diagnostic approach should be used before making treatment and management decisions for any individual patient. It is widely accepted that distinction among primary psychiatric disorders, epilepsy, and nonepileptic seizures is a challenge for physicians. This case series demonstrated the identification of three atypical presentations of seizures in children on the basis of detailed history taking and electroencephalogram findings, despite having normal findings in neurological examination and magnetic resonance imaging. We report three rare cases of atypical presentation in epilepsy in patients with symptoms of episodic hallucinations, rage attacks, and secondary enuresis. Clinically, the diagnosis of epilepsy can be strengthened by paying sufficient attention to detailed history and symptom spectrum of partial epilepsy.

A Threat to Autonomy? The Intrusion of Predictive Brain Implants

The world's first-in-human clinical trial using invasive intelligent brain devices—devices that predict specific neuronal events directly to the implanted person—has been completed with significant success. Predicting brain activity before specific outcomes occur brings a raft of unprecedented applications, especially when implants offer advice on how to respond to the neuronal events forecasted. Although these novel predictive and advisory implantable devices offer great potential to positively affect patients following surgery by enhancing quality of life (e.g., provide control over symptoms), substantial ethical concerns remain. The invasive nature of these novel devices is not unique; however, the inclusion of predictive and advisory functionalities within the implants, involving permanent monitoring of brain activity in real time, raises new ethical issues to explore, especially in relation to concerns for patient autonomy. What might be the effects of ongoing monitoring of predictive and advisory brain technologies on a patient's postoperative sense of autonomy? The role played by predictive and advisory implantable brain devices on patient's feelings of autonomy following surgery is completely unknown. The first section of this article addresses this shortcoming by reporting on a pilot study that we conducted with one of the patients implanted with one of these novel brain devices. The second section examines how overreliance on predictive and advisory brain technologies may threaten patients' autonomy. The third section looks into ethical problems concerning how devices delivering automated therapeutic responses might, hypothetically speaking, be used to monitor and control individual's autonomy through inhibition of undesirable behaviors.

Third International Congress on Epilepsy, Brain, and Mind: Part 2

Epilepsy is both a disease of the brain and the mind. Here, we present the second of two papers with extended summaries of selected presentations of the Third International Congress on Epilepsy, Brain and Mind (April 3-5, 2014; Brno, Czech Republic). Humanistic, biologic, and therapeutic aspects of epilepsy, particularly those related to the mind, were discussed. The extended summaries provide current overviews of epilepsy, cognitive impairment, and treatment, including brain functional connectivity and functional organization; juvenile myoclonic epilepsy; cognitive problems in newly diagnosed epilepsy; SUDEP including studies on prevention and involvement of the serotoninergic system; aggression and antiepileptic drugs; body, mind, and brain, including pain, orientation, the "self-location", Gourmand syndrome, and obesity; euphoria, obsessions, and compulsions; and circumstantiality and psychiatric comorbidities.

Ictal Forced Repetitive Swearing in Frontal Lobe Epilepsy: Case report and review of the literature

Introduction.Dominant presentation of ictal forced repetitive swearing has been rarely addressed and could be misdiagnosed.

Case report.We report a 45-year-old man with a long history of right frontal lobe epilepsy (FLE) who developed forced repetitive swearing during hypermotor seizures. His seizures were refractory to different antiepileptic drugs (AEDs). Scalp video-EEG telemetry suggested a right frontal epileptic focus. Magnetic resonance imaging (MRI) suggested focal cortical dysplasia (FCD) in the right mesial frontal lobe. Intracranial implantation with video-EEG recordings confirmed seizures originating from the MRI lesion. Patient underwent right frontal lobe resection followed by seizure freedom in the last five years on a single AED. Neuropathology confirmed FCD type IIB.

Discussion.The following aspects of the case are discussed: FLE and ictal vocalization, swearing, FLE and aggression. We emphasize the differences among ictal vocalisation, verbal automatism and ictal speech. We propose that ictal swearing might fit a verbal automatism definition.

Conclusion.Ictal forced repetitive swearing can be a manifestation of hypermotor seizures in FLE and should not be misdiagnosed.

Displaced aggression predicts switching deficits in people with temporal lobe epilepsy

This study examined the relationship between task-switching abilities and displaced aggression in people with temporal lobe epilepsy (PWE). Participants (35 PWE and 35 healthy controls) performed emotion and gender classification switching tasks. People with temporal lobe epilepsy showed larger switch costs than controls. This result reflected task-switching deficits in PWE. People with temporal lobe epilepsy reported higher anger rumination, revenge planning, and behavioral displaced aggression compared with controls. Displaced aggression was a significant predictor of the task switch costs. It is suggested that displaced aggression is a significant marker of task-switching deficits.

Self-harm in people with epilepsy: a retrospective cohort study

OBJECTIVES

Little is known about self-harm in people with epilepsy, despite suicide being recognized as a leading cause of mortality in this population. This study aimed to investigate the characteristics of self-harm in people with epilepsy, and associated demographic and psychosocial factors.

METHODS

Patients presenting to hospital following self-harm between 1994 and 2008 were identified from the Oxford Monitoring System for Self-Harm. Epilepsy diagnosis was confirmed through review of medical records. Demographic features, patient, and self-harm characteristics of 132 people with epilepsy and 9,778 self-harm patients without epilepsy were compared using a regression model, adjusting for age, sex, and repetition. Patients presenting between 1998 and 2008 were followed up for all-cause mortality to the end of 2011.

RESULTS

The rate of self-harm per individual with epilepsy was 2.04 (95% confidence interval [CI] 1.85-2.25) times that of the comparison group, and time between first and second self-harm events was shorter (hazard ratio 1.86; 1.46-2.38). People with epilepsy were significantly more likely to use antiepileptic medication in overdose, although overall methods of self-harm were similar in the two groups. No significant differences in suicide intent scores or the proportion of patients who died by suicide were found. Previous outpatient psychiatric treatment, longer duration of unemployment, experience of violence, and housing problems were associated with self-harm in people with epilepsy.

SIGNIFICANCE

People with epilepsy who self-harm do so more frequently than other self-harm patients. Clinicians should be aware of this and pay attention to contributory factors as these may enhance risk in this population.

Epilepsy and violence: case series concerning physical trauma in children of persons with epilepsy

Historically, epilepsy has been associated with violence, but more recent studies have emphasized genetic and psychosocial factors as more important. The case series presented here aim to highlight the difficult situation the affected children are in. We report on three cases when children have been traumatized and, in one case, even been killed by their parent who was diagnosed with epilepsy. In the first case, we describe a woman with juvenile myoclonic epilepsy who was sentenced to forensic psychiatry care for killing her child. She lived under difficult psychosocial circumstances and a suicide attempt contributed to what happened. The second case describes a man with post-traumatic seizures who was sentenced for child abuse. Ictal or postictal violence was considered in these two cases but a causal link between the violence and epilepsy has not been established. In the third case, we describe a woman with focal epilepsy and psychogenic non-epileptic seizures (PNESs). Her child was hurt and frightened in relation to violent seizures, which were regarded as PNESs. This case series demonstrates that children of parents with epilepsy can be in a vulnerable situation. No causality has been established between the seizures and these events, so consequently other factors such as psychosocial stress, low cognitive function, and a suicide attempt must also be considered as important. When a child is hurt by a parent with epilepsy the patient must be closely examined to determine the role of the seizures. Children can also be affected by PNESs. It is essential to notice especially those children of parents with epilepsy who live under difficult psychosocial circumstances and offer extra support when necessary.

Epilepsy-induced behavioral changes during the ictal phase

In epilepsy, experiential phenomena and behavioral manifestations may pose a number of problems in terms of differential diagnosis. From a clinical point of view, ictal psychiatric symptoms represent partial seizures, mainly partial ones. In the majority of cases, they are very brief (lasting from a few seconds to a few minutes), stereotyped, out of context, and frequently associated with subtle or overt automatisms and postictal confusion of variable duration. In some cases, such symptoms are followed by alteration of consciousness as the ictus evolves to a complex partial seizure or a generalized tonic-clonic seizure. This paper reviews clinically relevant behavioral patterns during seizures discussing clinical phenomenology and relevance in terms of lateralizing value.

Reversible antisocial behavior in ventromedial prefrontal lobe epilepsy

Frontal lobe dysfunction is known to be associated with impairment in social behavior. We investigated the link between severe pharmacoresistant frontal lobe epilepsy and antisocial trait. We studied four patients with pharmacoresistant epilepsy involving the prefrontal cortex, presenting abnormal interictal social behavior. Noninvasive investigations (video-EEG, PET, MRI) and intracerebral recording (stereoelectroencephalography (SEEG)) were performed as part of a presurgical assessment. Comprehensive psychiatric and cognitive evaluation was performed pre- and postoperatively for frontal lobe epilepsy, with at least 7years of follow-up. All patients shared a characteristic epilepsy pattern: (1) chronic severe prefrontal epilepsy with daily seizures and (2) an epileptogenic zone as defined by intracerebral recording involving the anterior cingulate cortex, ventromedial PFC, and the posterior part of the orbitofrontal cortex, with early propagation to contralateral prefrontal and ipsilateral medial temporal structures. All patients fulfilled the diagnostic criteria (DSM-IV) of antisocial personality disorder, which proved to be reversible following seizure control. Pharmacoresistant epilepsy involving a prefrontal network is associated with antisocial personality. We hypothesize that the occurrence of frequent seizures in this region over a prolonged period produces functional damage leading to impaired prefrontal control of social behavior. This functional damage is reversible since successful epilepsy surgery markedly improved antisocial behavior in these patients. The results are in line with previous reports of impairment of social and moral behavior following ventromedial frontal lobe injury.

Acute postictal confusion and violence: Two cases with unfortunate outcomes

Patients with temporal lobe epilepsy (TLE) often have a brief postictal state characterized by confusion and disorientation. Less common postictal behaviors include wandering and violence - both reactive and spontaneous. We describe two male patients with left TLE and unusual postictal states that led to unfortunate outcomes. The first patient's postictal state included an intense urge to peregrinate, as well as reactive violence. When a frightened houseguest prevented the patient from exiting his bedroom during a postictal state, the patient climbed out the window and fell to his death. The second patient's postictal state included menacing posturing, loud exclamation of guttural sounds or profanities, clapping or smacking his hands together, and punching nearby objects. During a postictal state at home, he grabbed a bat and destroyed furnishings. After he had two seizures at work followed by his typical postictal state, he was dismissed because of his perceived threat to coworkers.

Epilepsy and homicide

PURPOSE

We report the rare case of a patient with intractable epilepsy and escalating aggression, resulting in murder, who had complete resolution of her seizures and explosive behavior following a right temporal lobectomy.

PATIENTS AND METHODS

We searched the available literature from 1880 to 2013 for cases of epilepsy being used as a court defense for murder and collected information regarding the final sentencing outcomes. We selected 15 papers with a total of 50 homicides.

RESULTS

We describe the case of a 47-year-old woman with drug-resistant right temporal epilepsy who developed increasing emotional lability, outbursts of anger and escalating violent behavior culminating in a violent murder. The patient was imprisoned while awaiting trial. In the interim, she underwent a successful temporal lobectomy with full resolution of seizures, interictal rage and aggressive behaviors. After the surgery, her charges were downgraded and she was transferred to a psychiatric facility.

CONCLUSION

The aggressive behavior associated with epilepsy has been described in the literature for over a century. A link between epilepsy and aggression has been disproportionally emphasized. These patients share some common characteristics: they are usually young men with a long history of epilepsy and lower than average intelligence. The violent act is postictal, sudden-onset, more likely to occur after a cluster of seizures and is usually related with alcohol abuse.

Treatment with levetiracetam in a patient with pervasive developmental disorders, severe intellectual disability, self-injurious behavior, and seizures: a case report

Pervasive developmental disorder is characterized by various symptoms that often include self-injurious behavior (SIB). Episodes of SIB occur in the context of high emotional arousal, anger, or fear and may be related to epilepsy. We report the case of a 20-year-old man with pervasive developmental disorder presenting with SIB non-responsive to antipsychotic medication. Positron emission tomography showed a right temporoparietal hypometabolic focal lesion suggestive of an epileptic focus. Two weeks after initiation of levetiracetam (Keppra®), SIB disappeared, without recurrence 24 months later. Levetiracetam (Keppra®) may be beneficial for such patients.

Disrobing associated with epileptic seizures and forensic implications

Little is known about the clinical aspects and medico-legal consequences of disrobing in the context of epileptic seizures. Seizure-related disrobing may occur either as an ictal automatism or during the postictal period. Some patients may experience a seizure while already in the unclothed state, engage in ictal wandering, and thereby appear in public in the nude. Two cases involving disrobing associated with seizures captured via video-monitored electroencephalography are offered. An additional case reveals the legal consequences endured by one patient who experienced a nocturnal seizure and began wandering in an unclothed state. Collectively, these cases illustrate the medical reality of seizure-related disrobing and the related adverse effects on patients' quality of life. Disrobing associated with epileptic seizures carries the potential for serious legal consequences if not properly identified as an ictal phenomenon.

The Lombrosian prejudice in medicine. The case of epilepsy. Epileptic psychosis. Epilepsy and aggressiveness

In the nineteenth century, epilepsy became subject of experimental research. Lombroso established a relationship between epilepsy and criminality believing in the existence of epileptoid traits and atavism. He tried to demonstrate the common origin of epilepsy, criminality, and genius; factors deteriorating the CNS would act upon centers, which control behavior and ethics. This impairment would cause a lack of control on the lower nervous centers, reducing restraints of instincts and criminal behavior. He described developmental frontal cortex lesions in epileptic patients (today Taylor's dysplasia) and these observations supported the erroneous conviction of a relationship between criminality and epilepsy. Neurological, behavioral, and criminological sciences analyzed Lombroso's doctrine, whereas it was controversial that epileptic patients should be prone to violent actions and aggressive behavior. Today, there is an international panel of experts on epilepsy, which suggests five relevant criteria to determine if a crime committed with aggressiveness could result from epileptic seizures.

Characteristics of Epilepsy Patients who Committed Violent Crimes: Report from the National Forensic Hospital

Background and Purpose:

We investigated the clinical and criminal characteristics of patients with epilepsy who had committed violent crimes in order to understand the mechanism of violence and to prevent future criminal activity.

Methods:

We reviewed medical and legal reports of criminals with epilepsy who were incarcerated in the Korean National Forensic Hospital between October 2007 and September 2008.

Results:

Of 761 criminals admitted to the National Forensic Hospital, 17 patients (2.2%) were diagnosed with epilepsy. All of them had localization-related epilepsy, and no patient reported an overt seizure attack around the time of a crime. Psychosis was present in eight patients, and seven patients were in a drunken state at the time of the crimes. There was a positive correlation between the patients’ age at their first crime and their intelligence quotient score.

Conclusions:

These results suggest that most violent crimes take place during interictal periods, and diverse medical conditions, including inebriation, psychosis, and low intelligence, are associated with violent crimes among epileptic patients.

Violence and postictal psychosis: a comparison of postictal psychosis, interictal psychosis, and postictal confusion

The belief that epilepsy is linked with violent behavior acquired a highly stigmatizing value in the late 19th century on the basis of degenerative theory. This widespread medical view lost general acceptance among experts in the 1990s after several large-scale studies showed that aggressive phenomena can arise during epileptic seizures, but are extremely rare. The concept of postictal psychosis (PIP) shed a new light on this old dispute. With this concept, the significance of the chronological relationship between seizures and violent behaviors in patients with epilepsy is newly stressed, which made a simple "yes" or "no" answer to the question implausible. In this review, we discuss violent behaviors at five chronological points relative to seizures and demonstrate representative cases. As shown in our previous study, well-directed violent attacks occurred during 22.8% of the PIP episodes, 4.8% of the IIP episodes, and 0.7% of the postictal confusions. Compared with the other two situations, proneness to violence stood out in the PIP episodes. Suicidal attempts showed a similar trend. Purposeful, organized violence as a direct manifestation of seizures or ictal automatism is highly exceptional. Violent acts could occur in postictal confusion as an expression of unconscious, vigorous resistance against efforts of surrounding people to prevent the affected individual from roaming or fumbling about. In contrast, some PIP episodes can be highly alarming, especially if a violent act has been previously committed in preceding episodes. Violent acts by patients with epilepsy should be treated differently according to the various pathophysiological backgrounds from which the violence arises.

Treatment strategies in the postictal state

Postictal behaviors and symptoms often require special assessment and treatment. We review risk factors for postictal delirium and psychosis and management of agitated and confused behaviors in patients after seizures. Medical and emergency staff require careful training to manage behaviors associated with postictal delirium and psychosis in order to protect patients while their confusion resolves. Treatment of postictal states requires recognition of underlying neurological and systemic disorders associated with seizures and delirium such as metabolic disorders and nonconvulsive seizures. There is incomplete information about the causes and optimal treatments for seizure-related psychosis, however, postictal behaviors can usually be managed safely.

Neurocognitive and behavioral functioning in frontal lobe epilepsy: a review

Frontal lobe epilepsy (FLE) is a seizure disorder with a lower prevalence than temporal lobe epilepsy (TLE). Despite its consequences on cognitive and emotional well-being, the neuropsychology of FLE has not been well studied. By contrast, TLE has been studied meticulously, leading to a relevant understanding of memory and the functional characteristics of the temporal and limbic circuits. The neuropsychological studies on FLE report deficits in motor coordination and planning, reduced attention span, and difficulties in response inhibition in complex cognitive tasks. This review aims to illustrate the most relevant neurocognitive dimensions, psychiatric comorbidity, and postoperative neuropsychological outcome of FLE. Methodological suggestions for future research are also included by critically reviewing the existing literature.

Psychiatric outcome of surgery for temporal lobe epilepsy and presurgical considerations

In recent years, surgery has become a treatment option for some patients with intractable epilepsy, particularly those with temporal lobe epilepsy. Psychiatric disturbances may complicate the postsurgical outcome in some patients and de novo psychiatric symptoms have been reported. In many but not all epilepsy surgical centres, a psychiatric assessment is included as part of the presurgical evaluation of potential candidates for surgery. This review indicates that affective disorders, namely, depression and anxiety, and psychosis are the most frequently reported postsurgical psychiatric disturbances. Whilst there are no absolute psychiatric contraindications to surgery, certain pre-existing psychiatric conditions may need careful consideration as there may be a risk of postsurgical psychiatric complications. Routine pre- and postsurgical psychiatric evaluations in patients undergoing epilepsy surgery are recommended. Clinicians involved in the care of surgical candidates should be aware of the possible psychiatric complications following surgery and ensure that the psychiatric risks are discussed with the patient and family.

Subacute postictal aggression in patients with epilepsy

Three men with epilepsy (age range, 38-62) who exhibited brief episodes of violent behavior during the postictal period are described. Disease duration ranged from 27 to 44 years. Patients had both complex partial seizures and secondarily generalized tonic-clonic seizures, which were refractory to antiepileptic drugs. Postictal aggression occurred shortly after a seizure and lasted 5-30 minutes. The patients displayed physically and verbally aggressive behavior toward others, but regained consciousness promptly and showed regret afterward. Interictal EEGs revealed temporal spikes, SPECT showed hypoperfusion in the temporal and frontal areas in two patients, and neuropsychological examination revealed poor frontal lobe function in two patients. Characteristics of our cases are consistent with subacute postictal aggression (SPA) reported previously. Epilepsy of prolonged duration and brain dysfunction involving a broad area including the temporal and frontal lobes may be associated with the occurrence of subacute postictal aggression.
