Prior head injury accounts for the heterogeneity of the alcohol-epilepsy relationship

Clinical characteristics of seizure recurrence and epilepsy development in patients with alcohol-related seizures

BACKGROUND

Alcohol withdrawal is widely recognized as a trigger for acute symptomatic seizures among individuals with chronic alcohol consumption. While most alcohol withdrawal seizures occur shortly after cessation, chronic alcohol consumption can be associated with the development of epilepsy, necessitating anti-epileptic drug (AED) therapy. This study aimed to investigate the clinical characteristics, seizure recurrence, and epilepsy development in patients with alcohol-related seizures and to identify prognostic factors for epilepsy.

METHODS

In a retrospective analysis at Ewha Womans University Mokdong Hospital, 206 patients with alcohol-related seizures were examined and 15 were excluded due to preexisting epilepsy. Demographic and clinical data, including alcohol withdrawal duration, seizure recurrence, types, and comorbidities, were investigated. Logistic regression models were used to analyze the risk factors for seizure recurrence and epilepsy development. The performance of the final models was evaluated based on the area under the receiver operating characteristic curve (AUC) and validated using calibration plots and leave-one-out cross-validation.

RESULTS

Of the 191 patients (146 males; mean age 48.3 ± 12.1 years) with alcohol-related seizures, 99 patients (51.8%) experienced seizure recurrence and 79 patients (41.4%) developed epilepsy. Factors associated with seizure recurrence included alcohol consumption levels, occurrence of focal impaired awareness seizure, anxiety, and headache. The number of recurrent seizures, semiology, status epilepticus, electroencephalogram findings, and brain imaging findings was associated with epilepsy development. The predictive models showed strong diagnostic performance, with AUCs of 0.833 for seizure recurrence and 0.939 for epilepsy development.

CONCLUSION

High alcohol consumption and specific clinical and diagnostic features are significant predictors of seizure recurrence and the development of epilepsy among patients with alcohol-related seizures. These findings underscore the importance of early identification and intervention to prevent seizure recurrence and the onset of epilepsy, emphasizing the importance of AED treatment in managing these conditions.

Recommendations for Prescribing Opioids for People With Traumatic Brain Injury

Our objective was to make recommendations intended to reduce the rate of opioid misuse and overdose for a particularly high-risk group of people with traumatic brain injury (TBI). A consensus process conducted with TBI researchers and expert practitioners developed practical recommendations to inform prescribing of opioids for people with TBI. After determining key general principles for prescribing opioids for people with TBI, 6 TBI-specific recommendations were developed, 1 for acute pain in the agitated patient with TBI, 3 recommendations to be considered before prescribing an opioid, and 2 for follow-up and use by mental health and substance use disorder providers. While there is much needed research to examine the relationship between opioid misuse and TBI, the present recommendations provide at least some clinical considerations that might serve to prevent further deaths among a high-risk group.

Alcohol Use after Combat-Acquired Traumatic Brain Injury: What We Know and Don't Know

Military personnel engage in unhealthy alcohol use at rates higher than their same age, civilian peers, resulting in negative consequences for the individual and jeopardized force readiness for the armed services. Among those returning from combat deployment, unhealthy drinking may be exacerbated by acute stress reactions and injury, including traumatic brain injury (TBI). Combat-acquired TBI is common among personnel in the current conflicts. Although research suggests that impairments due to TBI leads to an increased risk for unhealthy drinking and consequences among civilians, there has been little research to examine whether TBI influences drinking behaviors among military personnel. This article examines TBI and drinking in both civilian and military populations and discusses implications for clinical care and policy.

Impact of age on long-term recovery from traumatic brain injury

OBJECTIVE

To determine whether older persons are at increased risk for progressive functional decline after traumatic brain injury (TBI).

DESIGN

Longitudinal cohort study.

SETTING

Traumatic Brain Injury Model Systems (TBIMS) rehabilitation centers.

PARTICIPANTS

Subjects enrolled in the TBIMS national dataset.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Disability Rating Scale (DRS), FIM instrument cognitive items, and the Glasgow Outcome Scale-Extended.

RESULTS

Participants were separated into 3 age tertiles: youngest (16-26y), intermediate (27-39y), and oldest (> or =40y). DRS scores were comparable across age groups at admission to a rehabilitation center. The oldest group was slightly more disabled at discharge from rehabilitation despite having less severe acute injury severity than the younger groups. Although DRS scores for the 2 younger groups improved significantly from year 1 to year 5, the greatest magnitude of improvement in disability was seen among the youngest group. In addition, after dividing patients into groups according to whether their DRS scores improved (13%), declined (10%), or remained stable (77%) over time, the likelihood of decline was found to be greater for the 2 older groups than for the youngest group. A multiple regression model showed that age has a significant negative influence on DRS score 5 years post-TBI after accounting for the effects of covariates.

CONCLUSIONS

This study supported our primary hypothesis that older patients show greater decline over the first 5 years after TBI than younger patients. In addition, the greatest amount of improvement in disability was observed among the youngest group of survivors. These results suggest that TBI survivors, especially older patients, may be candidates for neuroprotective therapies after TBI.
