In young adults aged 18 to 35, what is the most common cause of seizures?

In young adults aged 18 to 35, trauma is the most common cause of seizures. This demographic is more likely to engage in high-risk activities and behaviors, which can lead to head injuries from incidents such as motor vehicle accidents, falls, or physical altercations. Traumatic brain injury can result in post-traumatic seizures, either immediately after the injury or as a delayed response, making it a prevalent cause of seizures in this age group.

While alcohol withdrawal, brain tumors, and infections can certainly lead to seizures, they are less common in this specific age range compared to trauma. Alcohol withdrawal seizures typically occur in individuals with a history of chronic alcohol use, while brain tumors and infections may have more varied presentations depending on the individual and the circumstances, and they are not as frequently encountered as traumatic causes in this population.
