Childhood and parental characteristics of adults with DSM-5 intermittent explosive disorder compared with healthy and psychiatric controls.

ABSTRACT:

Background

Intermittent Explosive Disorder (IED) is a disorder primarily of aggression, defined by recurrent behavioral outbursts out of proportion to provocations or stressors. IED first appears in childhood and adolescence. This study examines the underlying childhood environment of those with IED, particularly familial and school-related factors.

Methods

Adult participants from a larger study completed diagnostic assessments and a battery of self-report measures. Group assignment was based on the assessment: 1) IED diagnosis; 2) non-IED psychiatric diagnosis; and 3) no significant psychiatric history. Groups were compared on factors of parental demographics, intrafamilial aggression, lifetime syndromal and personality diagnoses, neurodevelopmental and learning difficulties, childhood peer relationships, and juvenile legal issues.

Results

Significant patterns emerged specific to IED for not being raised by both parents, greater physical aggression to participant, and greater degree of fighting with peers by age ten.

Limitations

The retrospective, and cross-sectional, nature of the study, which prevent the making of causal inferences, and the basic nature of the questions asked of participants which limit a more nuanced interpretation of the data. A further limitation is bias associated with self-reported responses.

Conclusions

Results suggest the prevalence childhood adversaries may be linked with IED; the childhood environment of those with IED likely is substantially more tumultuous than individuals with or without other psychiatric disorders.

Project description:ImportanceIntermittent Explosive Disorder (IED) is an understudied psychiatric condition that presents with repeated episodes of impulsive aggression and poorly regulated emotional control, often resulting in interpersonal and societal consequences. Better understanding of comorbidities will allow for enhanced screening, diagnosis, and treatment of patients.ObjectiveTo investigate prevalence and associations of IED with psychiatric, neurological, and somatic disorders using real-world data.DesignMatched cohorts of patients with or without IED diagnosis were identified using data from the TriNetX Research Network (until January 31, 2024). Cox proportional hazard models were used to estimate and compare the probabilities of acquiring other diagnoses using patients' available medical records.SettingAnalysis of electronic medical records from two patient populations.Participants30,357 individuals with IED and equal number of demographically matched individuals without IED from the TriNetX Research.ExposureIED diagnosis identified through the associated ICD codes.Main outcomes and measuresThe main outcomes were ICD-10-CM diagnostic categories and root codes for disorders and health conditions in both cohorts. Main measures are total numbers and proportions of patients who had the diagnostic codes, as well as adjusted hazard ratios for IED diagnosis.ResultsAlthough only 0.03% of the total patient population had an IED diagnosis, we found extensive and widespread comorbidities with psychiatric, neurological and somatic conditions. A significant 95.7% of the individuals with IED had another psychiatric diagnosis. All psychiatric sub-categories and 95% of the psychiatric diagnoses were significantly associated with IED, with HRs ranging from 2 to 77. Among neurological conditions, neurodegenerative diseases and epilepsy had the highest HRs, followed by extrapyramidal and movement disorders, cerebral palsy and other paralytic syndromes, and sleep disorders. Notable associations with IED also includes conditions such as obesity, hyperlipidemia, hypertension, and GERD.Conclusion and relevanceOur findings illuminate the extensive comorbid relationships between IED and psychiatric, neurological, and somatic disorders. This underscores the necessity for an integrated diagnostic and treatment approach that addresses both the psychological and physical health aspects of IED. Additionally, our work highlights the need for more accurate and inclusive diagnosis of IED in patients with mental disorders.

Project description:ObjectivePosttraumatic stress disorder (PTSD) is associated with both aggressive and suicidal behavior. Recent research suggests that the diagnosis of intermittent explosive disorder (IED), an impulse-control disorder characterized by repeated impulsive aggressive behavior, may help to identify individuals at risk for attempting suicide. Given the relationship between anger and PTSD, there is likely to be an increased prevalence of IED among individuals with PTSD; however, little is known about the overlap in these two disorders, including how individuals with comorbid IED and PTSD may differ from those with either disorder alone. The purpose of this study is to examine the clinical correlates of comorbid IED and PTSD and the contribution of these two disorders (among others) to lifetime suicide attempt and characteristics of suicidal behavior.MethodIn a large sample of community research volunteers (N=1460), we compared individuals with PTSD, IED, and comorbid PTSD and IED on measures of current mood, trait aggression, and trait impulsivity. We also examined the contributions of PTSD, IED, and other syndromal and personality disorders to the prediction of lifetime aggression and lifetime suicide attempt, and their relationship to characteristics of suicide attempts, including level of intent, use of violent versus non-violent means, and the medical seriousness of the attempt.ResultsComorbid PTSD and IED was associated with significantly elevated levels of depression, anxiety, anger, aggression, and impulsivity, as well as with high rates of comorbidity with other psychiatric disorders. IED (β=.56, p<.001), but not PTSD, significantly and uniquely predicted lifetime aggressive behavior. Both IED and PTSD were associated with lifetime suicide attempt in multivariate analysis (ORs: 1.6 and 1.6, ps<.05). The results show that IED, when comorbid with PTSD, identifies a subgroup of individuals with particularly high levels of aggressive behavior and a high rate of suicide attempt (41.4% in this sample).ConclusionThese findings add support to the notion that the diagnosis of IED may aid in identifying individuals at risk for aggressive and suicidal behavior.
