Key result
Substance use was associated with a 57.1% prevalence of electroencephalographic changes, most commonly of moderate severity, with amphetamine being the most frequently implicated substance.
Why the study?
Substance abuse is a major global public health concern, prompting this study to determine electroencephalographic changes and evaluate clinical characteristics in patients with substance-related disorders.

No
EEG changes are highly prevalent (57.1%) in patients with substance-related disorders, particularly associated with amphetamine use and duration of use.

Substance abuse may associate with EEG changes; this cross-sectional observation leaves open prospective validation before clinical use.
Background: Substance abuse is defined as the hazardous use of psychoactive substances such as alcohol and illegal narcotics. It is a significant global public health concern. Chronic relapsing diseases, defined by compulsive use of drugs despite negative health effects, were substantial contributors to the illness burden in the USA and all over the world. Objective: The objectives were as follows: (a) to determine the presence of electroencephalographic (EEG) changes and their types among patients with substance-related disorders and (b) to evaluate the sociodemographic and clinical characteristics of patients with substance-related disorder. Materials and Methods: It was a cross-sectional study conducted from September 1, 2021 to August 1, 2022. It was performed on 112 patients (104 males and 8 females) in the Neurophysiology Department of Al Imam Al Sadiq Teaching Hospital in Al-Hilla Governorate. The patients were diagnosed by psychiatrists, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. All patients were assessed by history, physical examination, and EEG test. Results: The study showed that the frequency of EEG changes was 57.1%, whereas those without any changes was 42.9%. Those with score 2 or moderate severity were 53.6%. Severe abnormalities were found in 3.5% of the patients. There was a significant association between the EEG change and the type of substance taken, with a P -value of 0.008. The study showed the association between the EEG change and duration of substance taken, with a P -value of 0.0001, which was significant. There was a significant association between the type of substance taken and age ( P = 0.002). The association between the type of substance taken and gender, residence, and occupation was non-significant. Conclusion: The study concluded that the EEG changes were of high prevalence in patients with substance-related disorder. The most common abnormality was score 2 (moderate severity). The most common substance with an abnormal EEG change was amphetamine.
