“…A cross-sectional study with a large sample size in the United States further observed that hearing loss may be associated with substance use-related disorders (especially alcohol and prescription opioid use) among subjects aged ≤ 49 years [9]. Our study provides complete information about the connection between illegal drug use and hearing loss, and the findings in this study are consistent with the consequences of using illegal drugs in prior case reports and small trials [19,20,[28][29][30]. For instance, a woman attended a clinic for a profound bilateral hearing loss after an intravenous injection of cocaine [19].…”

The use of illegal drugs may be a risk factor of hearing loss. However, very few studies with large sample size have investigated the relationship between illegal drug use and hearing loss. Therefore, to evaluate the association between illegal drug use and hearing loss, this cross-sectional population-based study collected data from the US National Health and Nutrition Examination Survey 2011. The study included 1772 participants aged 20 to 59 years who underwent the Drug Use Questionnaire and Audiometry Examination. Of the 1772 participants in this study, 865 were men (48.8%) and 497 were illegal drug users. The mean (SD) age of the patients was 40.0 (11.4) years. After considering age, sex, and comorbidities, the participants who used illegal drugs were found to have higher risks of high-frequency hearing loss (adjusted odds ratio (OR), 1.69; 95% confidence interval (CI), 1.35–2.10) and overall hearing loss (adjusted OR, 1.69; 95% CI, 1.36–2.12) as compared with the nonusers. In the second analysis, the participants who used ≥ 2 types of illegal drugs were associated with higher risks of high-frequency hearing loss (adjusted OR, 1.57; 95% CI, 1.06–2.32) and overall hearing loss (adjusted OR, 1.60; 95% CI, 1.08–2.37). In the third analysis, cocaine use was associated with increased risks of high-frequency hearing loss (adjusted OR, 1.34; 95% CI, 1.01–1.77) and overall hearing loss (adjusted OR, 1.38; 95% CI, 1.04–1.82). The adjusted OR for overall hearing loss in the methamphetamine users was 1.54 (95% CI, 1.05–2.27) as compared with that in the nonusers. This study shows that illegal drug users might have a higher risk of overall hearing loss than nonusers. In addition, the analysis results demonstrated that the more kinds of illegal drugs used, the higher the risk of hearing loss. Further experimental and longitudinal research studies are required to confirm the causal relationship between illegal drug use and hearing loss.

“…The criteria for identifying the integrity of the auditory pathway were the presence of waves I, III and V, and the analysis of latency and interpeak intervals with reproducibility of tracings, following the normal parameters proposed. 22 The minimum number of sweeps was 2,048, and the number of artifacts did not exceed 10% of this figure.…”

Introduction The auditory system consists of sensory structures and central connections. The evaluation of the auditory pathway at a central level can be performed through behavioral and electrophysiological tests, because they are complementary to each other and provide important information about comprehension. Objective To correlate the findings of speech brainstem-evoked response audiometry with the behavioral tests Random Gap Detection Test and Masking Level Difference in adults with hearing loss. Methods All patients were submitted to a basic audiological evaluation, to the aforementioned behavioral tests, and to an electrophysiological assessment, by means of click-evoked and speech-evoked brainstem response audiometry. Results There were no statistically significant values among the electrophysiological test and the behavioral tests. However, there was a significant correlation between the V and A waves, as well as the D and F waves, of the speech-evoked brainstem response audiometry peaks. Such correlations are positive, indicating that the increase of a variable implies an increase in another and vice versa. Conclusion It was possible to correlate the findings of the speech-evoked brainstem response audiometry with those of the behavioral tests Random Gap Detection and Masking Level Difference. However, there was no statistically significant correlation between them. This shows that the electrophysiological evaluation does not depend uniquely on the behavioral skills of temporal resolution and selective attention.

“…Weich et al suggested that with time there was an increase in absolute and interpeak wave latencies; however, the prolongation was not significant; which was consistent with our study. 16 They also concluded that hearing loss is related to drug abuse; however, duration of the drug does not significantly affect the hearing loss as shown by no significant difference in absolute and interpeak latencies. Garg et al found the statistical difference of absolute latencies of waves of brainstem auditory evoked potentials (I, II, III, IV, V) of the right ear between drug abusers and controls.…”

Background: Organophosphate (OP) poisoning is a common cause of significant mortality and morbidity all over the world. In Asia, OP poisoning is the most common form of fatal self harm. Previous studies have suggested hearing loss due to OP poisoning. The aim of the study was to study audiological assessment in the patients with OP poisoning.Methods: 26 patients (age <50 years) of OP poisoning over a period of one year were included in the study following ethical approval from Institute Ethics Committee. 25 healthy subjects served as control. Each subject was subjected to brainstem evoked response audiometry (BERA) examination. Results: 50% patients with OP poisoning were aged between 20-29 years. Male outnumbered females in the patients (M:F- 17:9) as well as controls (M:F- 17:8). Only absolute wave-v latency (ms) was statistically significantly prolonged in cases when compared with controls in both right (0.035) as well as left ears (0.048). We found no statistical significant difference in interpeak wave I-III, III-V, I-V latency of both ears in cases when compared with controls. On second assessment in the patients, we observed a statistical significant decrease in absolute wave III and V latency, and interpeak I-III interval in right ear when compared with wave latency at first assessment. In left ear on second assessment, a significant decrease in absolute wave I, III, and V latency was observed in the patients.Conclusions: OP compounds may affect entire neural auditory pathway. Further studies with a large sample size are required for the assessment.

Abstract: Marijuana and crack/cocaine may cause diffuse disorders in the brainstem and compromise the transmission of auditory stimuli regardless of how long these substances are used for.
