  Intermittent explosive disorder can begin in childhood after the age of 6 years or during the teenage years. It’s more common in younger adults than in older adults. The exact cause of the disorder is not known. It may be caused by the living environment and learned behaviors, genetics, or differences in the brain. […] Most people with this condition grew up in families where explosive behavior and verbal and physical abuse were common. Children who see or go through this type of violence at an early age are more likely to have these same traits as they grow up. […] Genetics may play a role. There could be a gene related to the tendency to react more easily to stress. This gene may be passed down from parents to children. […] There may be differences in the structure, function and chemistry of the brain in people with intermittent explosive disorder compared with that of the brains of people who do not have the disorder.

• #1 Intermittent Explosive Disorder: Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/17786-intermittent-explosive-disorder

  Intermittent explosive disorder (IED) is a mental health condition marked by frequent impulsive anger outbursts or aggression. The episodes are out of proportion to the situation that triggered them and cause significant distress. […] Researchers are still trying to discover the exact cause of intermittent explosive disorder, but they think genetic, biological and environmental factors contribute to its development: […] Genetic factors: IED more commonly runs in biological families. Studies suggest that 44% to 72% of the likelihood of developing impulsive aggressive behavior is genetic. […] Biological factors: Studies show that brain structure and function are altered in IED. For example, brain magnetic resonance imaging (MRI) studies suggest that it affects the amygdala, which is the part of your brain involved in emotional functioning. In addition, studies show that the level of serotonin (a neurotransmitter and hormone) is lower than normal in people with IED. […] Environmental factors: Experiencing verbal and physical abuse in childhood and/or witnessing abuse during childhood appears to play a role in the development of IED. Having experienced one or more traumatic events in childhood also seems to play a role.

• #1 Intermittent explosive disorder – Wikipedia

  https://en.wikipedia.org/wiki/Intermittent_explosive_disorder

  Impulsive behavior, and especially impulsive violence predisposition, have been correlated to a low brain serotonin turnover rate, indicated by a low concentration of 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid (CSF). […] A putative hereditary component to low CSF 5-HIAA and concordantly possibly to impulsive violence has been proposed. […] A suggested explanation for IED is a polymorphism of the gene for tryptophan hydroxylase, which produces a serotonin precursor; this genotype is found more commonly in individuals with impulsive behavior. […] IED may also be associated with damage or lesions in the prefrontal cortex, with damage to these areas, including the amygdala and hippocampus, increasing the incidences of impulsive and aggressive behavior and the inability to predict the outcomes of an individual’s own actions. […] EDS was associated with limbic system diseases, disorders of the temporal lobe, or abuse of alcohol or other psychoactive substances.

  There are similar data supporting an inverse relationship between aggression and oxytocin. […] However, with the exception of manipulating 5-HT as a strategy to reduce or increase impulsive aggression, few studies have been conducted to explore how manipulating non-5-HT systems reduces, or has no effect on, impulsive aggressive behavior in humans. […] Similarly, studies of individuals with intermittent explosive disorder note categorical differences in structural and functional imaging studies as would be expected from studies of aggression in general. […] Individuals with intermittent explosive disorder display a reduction in gray matter volume in fronto-limbic circuits, abnormalities in the shape of the amygdala and hippocampus, and reduced fractional anisotropy in the superior longitudinal fasciculus, all suggesting important structural deficits in critical emotion regulating areas of the brain.

  Despite the possibility of a smaller, less smooth amygdala, functional fMRI studies note hyperactivity of the amygdala to hostile social threat in intermittent explosive disorder compared with healthy controls, with either unchanged or reduced activation of prefrontal cortical regions. […] Finally, we have found important differences in fMRI responses to videos displaying socially ambiguous situations in which one individual experiences a potentially aggressive event. […] Additionally, there have been several biological processes that have been noted to exist in those with intermittent explosive disorder, including associations between circulating inflammatory cytokines and aggression in human studies. […] It has been reported that the circulating levels of inflammatory cytokines such as C-reactive protein, interleukin-6, and interleukin-1RAII protein are higher in those with intermittent explosive disorder compared with healthy and psychiatric controls.

• #1 Intermittent Explosive Disorder: Why IED Isn’t About Anger Issues

  https://psychcentral.com/disorders/intermittent-explosive-disorder-ied

  Intermittent explosive disorder may be caused by a combination of psychosocial stressors, genetics, and life experiences. […] Research shows that IED is linked to being exposed to multiple traumatic events, physical abuse in childhood, personality disorders, and post-traumatic stress disorder (PTSD). […] Trauma can lead to changes in the brain. […] Researchers have noted that PTSD can cause reductions in gray matter, specifically. […] So far, research suggests that those who live with IED have a lower volume of gray matter and increased activity in the amygdala than folks not living with IED. […] While researchers don’t yet know what causes this condition, it appears to be a combination of genetic and environmental factors, specifically related to trauma.

  The research into the relationship between early life experiences, family environment, and IED suggests that there is a significant link between adverse childhood events, such as trauma, abuse, and neglect, and the later development of IED. […] Socioeconomic status emerges as another critical risk factor for exposure to trauma, with lower socioeconomic backgrounds being more prone to traumatic events. […] A complex interplay exists between early life experiences, family environment, and the development of IED.

• #1 7 Signs Of Intermittent Explosive Disorder In Adults

  https://missionconnectionhealthcare.com/mental-health/anger-issues/intermittent-explosive-disorder/

  Causes of Intermittent Explosive Disorder in Adults […] It’s impossible to pinpoint the causes of intermittent explosive disorder in adults, as research only shows us a relationship between two factors, not if one caused the other. However, we can see from the research that certain factors influence IED in adults, either by increasing the risk or often occurring alongside. These include: […] Studies show that roughly 35% of people with IED also struggle with depression, and around 58% have a diagnosable anxiety disorder. While it’s not clear which came first, IED or another mental health condition, mental ill-health may put people at higher risk for developing IED. More research is needed for us to really understand this. […] Traumatic past events are closely associated with the onset of IED, suggesting that these experiences may trigger IED. Traumatic events that occurred in childhood, such as witnessing family violence or being physically abused, appear to have the strongest link with IED.

  Intermittent Explosive Disorder Causes and Risk Factors […] Experts dont yet know what causes IED. But a few things may increase your chances of having the disorder, such as: […] Your genes. IED tends to run in families, so you could have inherited a gene that makes you more likely to have the disorder. As much as 72% of IED diagnoses are tied to a family history. […] Your environment. If you grew up in a household where IED behaviors, such as violent outbursts and physical and verbal abuse, were common, you are more likely to behave in a similar way. Traumatic experiences in childhood also may increase your risk. […] Your brain. Your brain structure and chemistry, as well as how your brain functions, may be different than that of someone who does not have IED. Research shows that people with IED have lower levels of a neurotransmitter hormone called serotonin. […] Having another mental disorder also increases your risk of developing IED.

• #2 Intermittent Explosive Disorder | Psychology Today

  https://www.psychologytoday.com/us/conditions/intermittent-explosive-disorder

  Intermittent explosive disorder appears to emerge from a combination of biological and environmental factors. There may be a genetic component through which susceptibility to the disorder is passed from parents to children. There is also some evidence that the neurotransmitter serotonin may play a role in the development of IED. But many people with the disorder also grew up in families in which explosive behavior and verbal and physical abuse were common. Being exposed to such violence as a child, research finds, makes one more likely to develop the same traits as they mature; in other words, at least in part, the behavior may be learned. […] People with intermittent explosive disorder may have differences in brain structure and function that distinguish them from others. Some research suggests that IED is linked to disruptions in serotonin pathways in the brain; other studies have found that it is associated with lower white matter integrity and lower grey matter volume in the connections between the frontal lobe and other brain regions. This deficit may contribute to impaired social cognition and greater difficulty regulating emotions.

  Following from this, it is not surprising that intermittent explosive disorder runs in families of first-degree relatives with intermittent explosive disorder by about 3-fold. […] From a psychobiological standpoint, aggression, particularly impulsive aggression, is associated with a reduction in central 5-HT function that is also observable in more distal indices of 5-HT function. […] These findings are highly consistent with animal studies reporting inverse relationships between 5-HT and aggression first reported in the literature in the 1960s. […] Other neurochemical systems may also be relevant in human aggression. […] At this time, there are preliminary data supporting positive relationships between aggression and catecholamines: norepinephrine, dopamine, and other amines such as glutamate; as well as peptides like vasopressin, substance P, and neuropeptide Y; and circulating cytokines such as interleukin-6.

  Some studies suggest that abnormalities of the brain that are responsible for regulating behavioral arousal and inhibition could be the cause. […] Developmental problems or Neurological symptoms maybe a cause. There may be an imbalance of serotonin or testosterone levels. […] Impulsive aggression is thought to be mainly defensive in nature, driven by fear, anger and a cognitive distortion of environmental conditions, with extremely high autonomic arousal. […] Neurobiological studies of aggression suggest that numerous neurotransmitters are disrupted. A disruption in the serotonergic system, in particular, low cerebral spinal fluid levels of 5-hydroxyindoleacetic acid, a serotonin metabolite, have been found in IED individuals.

  Genetic predispositions influence traits associated with aggression and impulsivity, although no specific gene has been definitively linked to IED. […] Neurotransmitter imbalances, particularly involving serotonin, play a crucial role in IEDs. Abnormalities in brain areas responsible for impulse control and aggression regulation lead to the disorders characteristic impulsive behaviors. Individuals with IED have lower gray matter volume in critical frontolimbic regions, including the orbitofrontal cortex, ventral medial prefrontal cortex, anterior cingulate cortex, amygdala, insula, and uncus. […] Childhood experiences significantly impact the development of IEDs. Exposure to violence, abuse, or harsh punishments during formative years increases the risk of developing aggressive behaviors later in life. Children who witness or experience aggression learn to react similarly when faced with negative stimuli. […] IED is a complex disorder with various contributing factors. While genetics and brain chemistry play a role, environmental influences also impact the disorders development. Understanding these factors helps in the early detection and effective treatment of IEDs.

  Childhood Intermittent Explosive Disorder is a complex neurobiological condition that significantly impacts a child’s behavior and well-being. Understanding the underlying causes, including neurobiology, trauma, and using evidence-based holistic treatment approaches, are vital for helping children with IED lead healthier, more stable lives. […] One important factor in understanding IED is the role of trauma. Many children with IED may have experienced traumatic events, which can trigger or worsen aggressive outbursts. Trauma can interfere with a child’s ability to regulate emotions, increasing the likelihood of intense reactions to seemingly minor stressors. […] Research suggests that IED may have a genetic component, as children with a family history of mood disorders, such as bipolar disorder or substance abuse, are at higher risk. Additionally, neurological differences, such as abnormal brain activity or neurotransmitter imbalances, can contribute to impulsivity and emotional regulation difficulties.

The observed behaviors result in physical assaults towards others or animals, property destruction, or verbal aggression. The recurrent aggressive outbursts are manifested by the following: […] Many risk factors have been identified with the development of Intermittent Explosive Disorder, such as: being male, young, unemployed, single, having lower levels of education, and being victim of physical or sexual violence. Intermittent explosive disorder is associated with anxiety and bipolar disorders. Individuals with this disorder have higher risks of developing substance use disorders. […] Treatment typically involves cognitive behavioral therapy focusing on changing thoughts related to anger and aggression and developing relaxation and coping skills. Sometimes, depending on a person’s age and symptoms, medication may be helpful.

  Research has found that a combination of genetic, physical, and environmental factors can contribute to an eventual diagnosis of intermittent explosive disorder. […] Twin studies have shown a strong genetic component in the diagnosis of intermittent explosive disorder. […] Brain chemistry is believed to be strongly tied to the diagnosis of intermittent explosive disorder. […] Many believe that the environment in which a person is raised can contribute to the development of IED. Experiencing physical or emotional trauma early in life could render a person more susceptible to a subsequent diagnosis.

  Following from this, it is not surprising that intermittent explosive disorder runs in families of first-degree relatives with intermittent explosive disorder by about 3-fold. […] From a psychobiological standpoint, aggression, particularly impulsive aggression, is associated with a reduction in central 5-HT function that is also observable in more distal indices of 5-HT function. […] These findings are highly consistent with animal studies reporting inverse relationships between 5-HT and aggression first reported in the literature in the 1960s. […] Other neurochemical systems may also be relevant in human aggression. […] At this time, there are preliminary data supporting positive relationships between aggression and catecholamines: norepinephrine, dopamine, and other amines such as glutamate; as well as peptides like vasopressin, substance P, and neuropeptide Y; and circulating cytokines such as interleukin-6.

  Despite the possibility of a smaller, less smooth amygdala, functional fMRI studies note hyperactivity of the amygdala to hostile social threat in intermittent explosive disorder compared with healthy controls, with either unchanged or reduced activation of prefrontal cortical regions. […] Finally, we have found important differences in fMRI responses to videos displaying socially ambiguous situations in which one individual experiences a potentially aggressive event. […] Additionally, there have been several biological processes that have been noted to exist in those with intermittent explosive disorder, including associations between circulating inflammatory cytokines and aggression in human studies. […] It has been reported that the circulating levels of inflammatory cytokines such as C-reactive protein, interleukin-6, and interleukin-1RAII protein are higher in those with intermittent explosive disorder compared with healthy and psychiatric controls.

  Intermittent Explosive Disorder Causes and Risk Factors […] Experts dont yet know what causes IED. But a few things may increase your chances of having the disorder, such as: […] Your genes. IED tends to run in families, so you could have inherited a gene that makes you more likely to have the disorder. As much as 72% of IED diagnoses are tied to a family history. […] Your environment. If you grew up in a household where IED behaviors, such as violent outbursts and physical and verbal abuse, were common, you are more likely to behave in a similar way. Traumatic experiences in childhood also may increase your risk. […] Your brain. Your brain structure and chemistry, as well as how your brain functions, may be different than that of someone who does not have IED. Research shows that people with IED have lower levels of a neurotransmitter hormone called serotonin. […] Having another mental disorder also increases your risk of developing IED. For example, if you have: Attention deficit hyperactivity disorder (ADHD) […] Antisocial personality disorder […] Borderline personality disorder […] Depression […] Anxiety […] Substance abuse disorder.

  However, not everyone who experiences childhood trauma will develop IED, and not all individuals with IED have a history of childhood trauma. The relationship between childhood trauma and IED is complex, and—as mentioned—other risk factors, such as genetic predisposition, biological factors, and environmental influences, can also contribute to the development of the disorder.

  Intermittent explosive disorder is a condition marked by unwarranted and disproportionate episodes of rage. […] As with many mental health conditions, anger disorders like IED can have a variety of causes. Here are few of the most common examples: A genetic predisposition to developing IED, imbalances in brain chemistry, such as with serotonin levels that regulate emotion, past exposure to physical or emotional abuse, especially trauma during childhood. […] Intermittent explosive disorder is also linked to preexisting mental and behavioral health conditions. According to the National Institutes of Health (NIH), 82% of people with IED have a history of depression, anxiety or substance abuse.

  The exact etiology of impulsive aggression in the context of intermittent explosive disorder remains to be defined, but clearly is multidetermined in nature with contributions from genetics, neurochemistry, and cortico-limbic function. […] Aggression is under both genetic and environmental influence, with up to 50% of the variability in measures of aggression accounted for by genetic factors. […] Our own twin studies using aggression support this, showing genetic influence of the aggression increasing with the severity of the aggressive acts from 28% for verbal aggression to 45% for aggression against others. […] In addition, impulsivity is under similar genetic influence in these types of studies and the genetic correlation of impulsivity and aggression is correspondingly substantial, supporting the conceptualization of aggression as a form of dysregulation.

  Intermittent explosive disorder may have a genetic component, potentially passed down through generations. Individuals with a family history of impulse-control disorders may have a higher risk. […] Children raised in environments where verbal abuse, physical violence, or frequent angry outbursts are common have an increased likelihood of developing IED. […] Multiple adverse childhood events or traumatic situations can predispose an individual to IED, compounding genetic and environmental factors. […] Low levels of serotonin in the brain (often indicated by decreased 5-HIAA in the cerebrospinal fluid) may contribute to impulsive and aggressive behavior. […] Lesions or dysfunctions in the prefrontal cortex and amygdala, which are areas of the brain regulating impulses, decision-making, and emotional responses, can exacerbate aggressive outbursts. Impaired blood sugar control in these areas may also affect impulse regulation.
