Many viewers of Young Sheldon and The Big Bang Theory tend to assume that Sheldon Cooper has autism spectrum disorder (ASD) or obsessive-compulsive disorder (OCD). However, the creators and producers behind the shows have stated that Sheldon was not written as a character with any specific psychological or psychiatric disorder. They deliberately avoided assigning him a medical diagnosis and instead intended his behaviors to be understood simply as part of his distinctive personality.
As a subtle way of addressing the audience’s questions, often through scenes in which Sheldon’s behavior drives those around him to exasperation, whenever someone suggests that there may be something neurologically wrong with him, he always responds, “I’m not crazy. My mom had me tested.” Nevertheless, my love-hate relationship with the character makes it difficult for me to regard him as entirely ordinary. After all, few ordinary people possess such a striking combination of eccentricity, intellectual superiority, self-centeredness, disregard for others’ opinions, limited social skills, and extreme rigidity, while at times also displaying affection, emotional understanding, and an almost childlike quality that makes him remarkably difficult to dislike.
This is the reason this article was written. Drawing on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), published by the American Psychiatric Association (APA) in 2022, I will examine Sheldon from a psychological perspective and consider whether there is sufficient evidence to conclude with certainty that he has any particular mental disorder or psychiatric condition.

What I found most intriguing after completing this article was not the attempt to prove that Sheldon fits a particular diagnosis, but rather the realization that no diagnosis in the DSM-5-TR seems capable of fully capturing who he is as a character. The more I tried to assign him a specific diagnostic label, the more apparent it became that Sheldon consistently exceeds the boundaries of such classifications.
He embodies the familiar “eccentric genius” archetype often portrayed in popular culture, yet he is also presented as a remarkably ordinary human being: sincere and uncomplicated, with his own strengths, weaknesses, and personality traits that remain distinctly childlike.
