Schizoid personality disorder is a condition characterized by a lack of interest and ability to form relationships with others. People with this disorder often keep to themselves, have difficulty expressing emotions, and may not be interested in forming close friendships or romantic relationships. Schizoid personality disorder is less common than other personality disorders but more common than schizophrenia. The exact cause of the disorder is not known, but it may be influenced by a combination of genetics and environmental factors.


Common symptoms of schizoid personality disorder include a preference for being alone and doing activities alone, little desire for close relationships or sexual relationships, limited enjoyment in activities, difficulty expressing emotions, lack of interest in others, and a lack of drive to achieve goals. People with schizoid personality disorder may also appear odd or unusual to others. Symptoms often begin in young adulthood but may be noticed during childhood. These symptoms can impact various areas of life, such as school, work, and social situations.

Schizoid Personality Disorder and Schizophrenia

Schizoid personality disorder is different from schizotypal personality disorder and schizophrenia spectrum disorders, although they may share some similar symptoms, such as difficulty making social connections or showing a full range of emotions. Unlike schizophrenia, people with schizoid personality disorder are in touch with reality and do not typically experience paranoia, hold bizarre beliefs, or hallucinate. Their speech may lack liveliness, but it remains coherent and understandable.

When to See a Doctor

People with schizoid personality disorder often seek treatment for related problems, such as depression. If you or someone you know is experiencing symptoms common to schizoid personality disorder, it is essential to make an appointment with a doctor or mental health professional. Encourage your loved one gently to seek help, and offer to accompany them to the first appointment if needed.


The exact cause of schizoid personality disorder is not known, but it is believed to result from a combination of genetic and environmental factors. Personality forms during childhood and is shaped by a mix of genetics and surroundings.

Risk Factors

Factors that increase the risk of schizoid personality disorder include having a parent or relative with a similar disorder or schizophrenia and having a parent who was emotionally neglectful or cold.


People with schizoid personality disorder are at higher risk of developing other personality disorders, major depression, anxiety disorders, schizotypal personality disorder, or schizophrenia.

Diagnosis of schizoid personality disorder involves ruling out other medical health problems through a physical exam. Your primary care doctor may then refer you to a mental health professional for further evaluation. The mental health professional will talk to you about your symptoms and medical history to determine if you have schizoid personality disorder.


If you have schizoid personality disorder, you may be hesitant to seek treatment due to your inclination to be alone and not interact with others, including healthcare professionals. However, working with a skilled mental health professional can greatly improve your quality of life. Treatment options for schizoid personality disorder include:

  • Talk therapy: Forms of cognitive behavioral therapy can help you change beliefs and behaviors that affect your relationships. A therapist will provide support and help you work towards your identified goals.
  • Group therapy: Participating in a group setting can help you learn and practice new social skills with others who are also working on improving their social interactions.
  • Medicines: Although there is no specific drug to treat schizoid personality disorder, certain medications may be prescribed to address issues like anxiety or depression.

With proper treatment and the guidance of a skilled therapist, significant progress can be made, and your quality of life can improve.

Preparing for Your Appointment

To prepare for your appointment, make a list of your symptoms, personal information, medical history, and all medications you take. Additionally, prepare questions to ask your doctor or mental health professional during the appointment. Taking a family member or friend along can be helpful, as they may provide additional information about your behavior.

Questions to Ask Your Doctor

Some basic questions to ask your doctor or mental health professional include:

  • What is likely causing my symptoms or condition?
  • What are other possible causes?
  • Is my condition likely short term or long term?
  • What treatments are most likely to help me?
  • If you suggest medicine, what are the possible side effects?
  • How much can I expect my symptoms to improve with treatment?
  • I have other health conditions. How can I best manage them together?

Feel free to ask any other questions you may have during the appointment.

What to Expect from Your Doctor

During your appointment, your doctor or mental health professional is likely to ask you several questions to understand your condition better. Be prepared to answer questions about your symptoms, social interactions, hobbies, thoughts, and family history of mental health conditions.
