These 5 manifestations of Sheldon Cooper’s OCD will be discussed in further detail below after taking a deeper look at the disorder of OCD and the character of Sheldon Cooper. 

What is OCD?

Obsessive-compulsive disorder (OCD) is characterised by a pattern of unwanted thoughts and anxieties (obsessions) that cause you to engage in repetitive actions (compulsions). Obsessions and compulsions create severe suffering and interfere with daily tasks.

You can try to ignore or stop your obsessions, but this will only make you feel worse. Finally, you feel compelled to engage in obsessive behaviours in order to relieve your tension. Despite attempts to ignore or eliminate troublesome thoughts or desires, they persist. This feeds into the OCD’s vicious circle of ritualistic activity.

OCD is frequently centred on specific themes, such as an excessive fear of being contaminated by germs. You can wash your hands till they’re painful and chapped to alleviate your contamination anxieties. If you have OCD, you may feel ashamed and embarrassed about it, but there is help available.

What are the symptoms of OCD?

Obsessions and compulsions are common in obsessive-compulsive disorder. However, just obsessive symptoms or simply compulsion symptoms are feasible. 

You may or may not recognise that your obsessions and compulsions are excessive or unjustified, yet they consume a significant amount of time and disrupt your daily routine, as well as your social, school, and professional functions.

Obsession symptoms.

Obsessions with OCD are intrusive, recurring, and unwelcome thoughts, impulses, or visions that create anguish or worry. You might try ignoring them or executing a compulsive activity or routine to get rid of them. Obsessions usually pop up when you’re attempting to think of or accomplish anything else.

Obsessions frequently have themes, such as –

  • Contamination or dirt phobia
  • Doubting oneself and finding it difficult to accept ambiguity
  • Needing things to be symmetrical and orderly
  • Thoughts of losing control and injuring yourself or others that are aggressive or horrifying
  • Unwanted ideas, such as violence, as well as sexual or religious topics

The following are some examples of obsessive indications and symptoms:

  • Fear of becoming infected by touching items that have been touched by others
  • Doubts regarding having locked the door or turned off the stove
  • When things aren’t in order or facing the right way, it causes a lot of tension.
  • Driving your automobile into a throng of people is an image that comes to mind.
  • Unpleasant sexual imagery Thoughts like yelling obscenities or acting improperly in public
  • Avoiding circumstances that may cause obsessions, such as shaking hands.

Compulsion symptoms.

Compulsions are recurrent activities that you feel compelled to do because you have OCD. These habitual activities or mental acts are intended to alleviate anxiety caused by your obsessions or to prevent anything awful from occurring. 

Compulsions, on the other hand, provide no pleasure and may only provide a momentary reprieve from tension. When you’re having obsessive thoughts, you might set up rules or routines to assist you to regulate your anxiety. These compulsions are extreme, and they’re often unrelated to the problem they’re supposed to solve.

Compulsions, like obsessions, usually have a theme, such as –

  • Cleaning and washing
  • Checking
  • Counting
  • Orderliness
  • Sticking to a rigorous schedule
  • Requiring assurance

The following are some examples of compulsive signs and symptoms –

  • Hand-washing until your skin is red and irritated
  • Checking doors to make sure they’re locked on a regular basis
  • Checking the stove to make sure it’s turned off on a regular basis
  • Counting in particular patterns is a fun way to pass the time.
  • Repeating a prayer, statement, or phrase silently
  • Organize your canned goods so that they all face the same direction.

OCD generally develops in adolescence or early adulthood, although it can sometimes begin in childhood. Symptoms normally appear gradually and progress in intensity over time. 

Obsessions and compulsions can change over time, as can the sorts of obsessions and compulsions you have. When you’re under a lot of stress, your symptoms usually get worse. 

OCD, which is commonly seen as a lifelong condition, can manifest itself in mild to moderate symptoms that can be so severe and time-consuming that it becomes incapacitating.

What are the causes of OCD?

The exact aetiology of obsessive-compulsive disorder is unknown. The following are some of the most popular theories –

  • Biology – Changes in your body’s natural chemistry or brain functioning might cause OCD.
  • Genetics – Although OCD may have a hereditary component, no particular genes have been discovered.
  • Learning – Obsessive phobias and obsessive habits can be learnt through observation of family members or through time.

What are the risk factors associated with OCD?

The following factors may raise your chances of acquiring or causing obsessive-compulsive disorder –

  • History of the family – Having OCD-affected parents or other family members increases your chances of having the illness.
  • Life experiences that are stressful – Your risk may arise if you’ve been through traumatic or stressful experiences. This reaction could, for whatever reason, set off OCD’s intrusive thoughts, rituals, and emotional distress.
  • Other types of mental illnesses – Other mental health conditions, such as anxiety disorders, depression, substance misuse, or tic disorders, may be linked to OCD.

What are the complications involved in OCD?

Obsessive-compulsive disorder can cause a variety of issues, including:

  • Excessive time spent on ritualistic activities
  • Contact dermatitis from regular hand washing is one example of a health problem.
  • Attending job, school, or social events with difficulty
  • Relationships that are in trouble
  • Overall, the quality of living is terrible.
  • Suicidal ideas and actions

Who is Sheldon Cooper?

Caltech theoretical physicist Dr. Sheldon Lee Cooper, B.Sc., M.Sc., M.A., Ph.D., Sc.D., is a B.Sc., M.Sc., M.A., Ph.D., Sc.D. He is the main protagonist of The Big Bang Theory and the titular protagonist of Young Sheldon, with his closest pal Leonard Hofstadter.

Sheldon, a native of East Texas, began education at the age of 11 and received his first Ph.D. at the age of 16. 

Sheldon participated in various projects as a child as a “wunderkind,” such as his idea to build a nuclear reactor to offer free power to his village – a scheme that was thwarted by government pen-pushers who claimed it was unlawful to keep yellowcake uranium in a garden shed.

He has no qualms about speaking Klingon, wearing old t-shirts with super-hero insignia, or reciting numerous historical and cultural tales, and he is proud of it (e.g., his account of the introduction of the fork into Thailand). Sheldon, while claiming to be the ultimate human specimen, is not without flaws. 

Sheldon is defined by strict adherence to routine and hygiene, an overly intellectual personality, a shaky understanding of irony, sarcasm, and humour, and a general lack of humility or empathy, the former of which is demonstrated by his willingness to express his admiration for his superior intellect to his peers.

His character’s major source of humour comes from these attributes, as well as his fondness for pranks. He is widely regarded as the show’s most recognisable character. 

Because of the influence of his buddy Penny and his wife Amy, Sheldon has acquired a more gregarious attitude, albeit some of it may not always show up.

What are these 5 signs that indicate that Sheldon Cooper has OCD?

“That’s my spot.”

Sheldon has his own dedicated position on the couch in Leonard and Sheldon’s apartment’s living room. This is a self-designated area, and anybody sitting there wreaks havoc with Sheldon’s mental health.

“Knock Knock Knock, Penny.” 

Sheldon has to knock three times on Penny’s door and say her name each time. This has to be done three times for Sheldon to feel satisfied. And if this practice were to be disrupted, Sheldon would be much more frustrated.

Food habits are set in stone.

Sheldon’s OCD causes him to be afraid of the unknown, which he combats by creating a routine for everything. His dinners are meticulously prepared for each day of the week, and even the tiniest hiccup in the routine may throw his life into turmoil. In addition, he only consumes hot chocolate during the months that begin with the letter R.


Sheldon is terrified of germs and needs to correct every incident when he drinks someone else’s water or uses someone else’s napkin out of fear for his life. This is also why he has a hard time visiting hospitals.

There is a need for closure.

Amy, Sheldon’s girlfriend, tries to heal his OCD by rewriting his brain’s neuronal make-up in one of the episodes. She does this by not allowing him to finish anything, such as rubbing off the last line of the national anthem right before the completion of a game of tic tac toe. As one might think, this irritates him to no end.

Sheldon’s behaviour has been researched by psychologists, and he has been diagnosed with Narcissistic personality disorder, Borderline personality disorder, and Paranoid personality disorder, in addition to OCD.
