Alcohol can be an unspoken and underrecognized factor influencing some cases of autism spectrum disorder (ASD), particularly in special education contexts, but its role is complex and indirect rather than causal. Research indicates that individuals with ASD may have increased vulnerability to substance use disorders (SUD), including hazardous alcohol use, which can exacerbate symptoms and complicate clinical presentations[1].
Autism spectrum disorder is a neurodevelopmental condition characterized by difficulties in social communication, repetitive behaviors, and sensory processing abnormalities[5]. While alcohol itself is not a cause of autism, studies have shown that individuals with ASD may engage in substance use, including alcohol, as a coping mechanism for anxiety, sensory dysregulation, or social challenges. For example, a case report highlighted a patient with ASD who initially struggled with hazardous alcohol use, which was linked to sensory and anxiety-related features of autism. This patient’s alcohol use was followed by other substance use and eating disorders, illustrating how alcohol can be part of a complex clinical picture in ASD[1].
The relationship between alcohol and ASD is further complicated by the fact that autistic individuals often experience higher rates of anxiety and mood disorders, which can increase the risk of self-medication with substances like alcohol[3]. Anxiety is significantly more prevalent in autistic children compared to non-autistic peers, and this heightened anxiety may drive some to use alcohol to manage distress, despite potential negative consequences[3].
From a medical perspective, alcohol use in individuals with ASD can worsen cognitive and behavioral symptoms. Alcohol affects brain function by altering neurotransmitter systems and can impair executive functioning, which is already a challenge in ASD. Moreover, alcohol use disorder (AUD) can lead to physical health problems and exacerbate co-occurring mental health conditions common in autism, such as depression and anxiety[1][4].
It is important to distinguish between prenatal alcohol exposure and alcohol use by individuals with ASD. Prenatal alcohol exposure can cause fetal alcohol spectrum disorders (FASD), which share some behavioral features with ASD but are distinct conditions caused by alcohol’s teratogenic effects during pregnancy. This is a separate issue from alcohol use by autistic individuals themselves[1].
In summary, while alcohol is not a direct cause of autism, it can be an unspoken factor in the lives of some autistic individuals, particularly those in special education who may have additional vulnerabilities. Alcohol use may arise as a maladaptive coping strategy linked to sensory sensitivities, anxiety, or social difficulties inherent in ASD. Recognizing and addressing alcohol use in this population is critical for effective treatment and support.
