Schizotypal Personality Disorder is a mental health condition affecting a person’s thinking, behavior, and emotions. People diagnosed with this disorder are often described as eccentric and struggle to build close relationships or fit into social groups. While only four percent of the global population is estimated to have schizotypal personality disorder, understanding its symptoms and treatments is important to help those who might be at risk. In our article, we take a closer look at the causes of schizotypal personality disorder and effective ways to manage it.
What Is Schizotypal Personality Disorder?
Schizotypal Personality Disorder (STPD) is a mental health disorder characterized by abnormal patterns of thinking, impaired behavior, and emotional instability. Individuals with this disorder often act oddly, struggle in social settings, and fail to cultivate close relationships.
This disorder is considered to be one of ten personality disorders a person may develop. It shares certain symptoms with schizophrenia—another mental health disorder from the same spectrum—however, STPD is a standalone diagnosis with unique traits and treatments.

Symptoms of Schizotypal Personality Disorder
Here is a list of schizotypal personality disorder symptoms you should look out for:
- Discomfort in Social Situations. A person with STPD may feel like they do not belong during social events, have trouble coming up with things to say when talking to other people, and decide to be on their own instead of spending time in the company of others.
- Lack of Close Relationships. While some people are capable of making acquaintances and friends, in many cases, STPD leads to social anxiety and isolation.
- Inappropriate Affect. Individuals with this disorder may struggle to react properly during a conversation—for instance, they may remain impassive when someone tells them a joke.
- Odd Behavior and Speech. If a person dresses eccentrically, has unusual mannerisms, and their speech lacks cohesion, this may be a sign of STPD.
- Ideas of Reference. People with this disorder may be falsely convinced the actions of others are somehow related to them. For example, they may believe a stranger on the street was talking about them when, in reality, this never happened.
- Unusual Beliefs. Sometimes, STPD is manifested in bizarre beliefs and thoughts that have no basis or proof. This may include superstitions and beliefs in telepathy or magic.
Causes of Schizotypal Personality Disorder
At the moment, there is no known cause of schizotypal personality disorder; nevertheless, mental health professionals have determined several risk factors associated with this diagnosis:
- Genetics. If a close relative of a person—for example, their parent or sibling—was diagnosed with STPD or schizophrenia, it increases their chances of having the same disorder.
- Brain Structure. Studies have shown the brains of people with STPD have structural peculiarities that differentiate them from healthy individuals. It is believed these abnormalities affect a person’s behavior and cognition.
- Prenatal Environment. There is a link between STPD and the health of the mother during pregnancy. If a woman suffered from an illness while being pregnant or consumed harmful substances during this time, it could have impacted the mental health of the unborn child.
- Negative Childhood Experiences. Often, mental health issues stem from childhood trauma. Physical, emotional, or sexual abuse, the death of a parent, or bullying may lead to STPD down the road.

Complications Associated With Schizotypal Personality Disorder
Failing to diagnose and treat schizotypal personality disorder may lead to various issues and negatively affect the life of the individual:
- Anxiety Disorders. It is possible that STPD will result in phobias and constant worry. For instance, a person may start feeling paranoid believing those around them want to harm them.
- Depression. When a person is incapable of building friendships and participating in social activities, they may end up feeling lonely and isolated, which will lead to major depression and even suicidal thoughts.
- Substance Abuse. Sometimes people cope with their mental health struggles by drinking alcohol and taking drugs. This harmful behavior may become an addiction and shorten the lifespan of the individual.
- Poor Social Skills. Odd behavior and speech patterns associated with STPD will make it difficult to fit in. A person may skip school and fail to hold a job if their eccentric manners are not addressed in therapy.
Diagnosis of Schizotypal Personality Disorder
If you suspect either you or someone you care about has STPD, reach out to a mental health professional. A therapist or psychiatrist will be able to determine whether a person has this disorder.
The healthcare provider will conduct a physical exam of the patient to learn about their medical history and find out whether their behavior may be explained by a physical illness or injury. There will be a series of lab tests to check, among other things, the hormone levels of the patient. Finally, the patient and the doctor will have a lengthy conversation to go over the symptoms and the lifestyle of the former to understand how STPD has affected their life.
How to Treat Schizotypal Personality Disorder
Fortunately, there are ways to treat schizotypal personality disorder and help a person manage their symptoms. Here are a few treatment options to consider:
- Medication. A psychiatrist may prescribe antipsychotic medication to their patient—these drugs will eliminate delusions and hallucinations and help the individual think more clearly.
- Therapy. There are several types of psychotherapy that can be beneficial for a person with STPD. Schedule an appointment with a licensed therapist and they will advise you on the best type of therapy for the patient—for example, cognitive-behavioral therapy will allow the person to understand
which thought patterns are harmful and gradually change their thinking. - Support From Loved Ones. Family and friends of the person diagnosed with STPD should be patient and understanding. Talk to the therapist of your loved one to learn how you can support them—sometimes, small accommodations
