Schizotypal Personality Disorder Symptoms


Schizotypal Personality Disorder (SPD) is a psychological disorder characterized by odd beliefs and behaviors, along with a lack of social skills and close relationships. SPD is classified as a cluster A personality disorder in the DSM-5. The exact causes of SPD are yet to be understood, but both genetic and environmental factors are believed to play a role.

In this article, we will describe the various symptoms and signs of SPD, along with the diagnosis, treatment, and potential recovery.

Symptoms and Signs of Schizotypal Personality Disorder

Individuals with SPD often display bizarre beliefs and behaviors, leading to a noticeable difference from the rest of society. The symptoms of SPD typically emerge in early adulthood, and include the following:

1. Eccentric Beliefs and Behaviors

People with SPD may hold unusual beliefs, such as believing in paranormal activity, or that they have unusual mental abilities. Their perceptions may be unusual, and they may think that they can read other people’s thoughts or that they are being controlled from afar.

2. Odd Speech Patterns

People with SPD may have peculiarities in their speech patterns, including using made-up words, cryptic language, and odd syntactic structures.

3. Difficulty in Maintaining Social Relationships

People with SPD may have trouble forming and maintaining close relationships with others. They may appear to prefer to be alone or may actively avoid social interaction.

4. Paranoia and Suspiciousness

People with SPD may have a marked tendency to be distrustful of others, leading them to avoid social situations and conversations.

5. Anxiety and Depression

People with SPD may experience anxiety and depression, leading them to feel uncomfortable in social situations and to have difficulty engaging with others.

6. Unusual Behaviours

People with SPD may engage in strange behaviors, such as wearing unusual clothes, misusing personal hygiene products, and exhibiting inappropriate emotional responses.

Diagnosis of Schizotypal Personality Disorder

SPD symptoms can be fairly subjective, and diagnosis often relies on the individual’s willingness to participate in screening and assessment. Diagnosis of SPD is made through a combination of psychological assessments, interviews with a mental health professional, doctors or ministers, and self-reporting of symptoms by the individual. A physical examination of the individual may also be done to rule out any physical causes for their symptoms.

Treatment of Schizotypal Personality Disorder

SPD is a difficult disorder to treat because it often requires long-term psychotherapy, with a focus on changing the way the individual views and interacts with the world. The following are the most common treatments used for SPD:

1. Cognitive Behavioral Therapy (CBT)

CBT is a type of therapy that focuses on changing negative patterns of thoughts and behaviors. The therapist may work with the individual to challenge their distorted beliefs and to develop new coping skills.

2. Supportive Therapy

Supportive therapy aims to provide emotional support and to develop trust with the individual. Through this therapy, individuals can discuss their feelings without fear of judgment.

3. Medication

Medications can be used to treat some of the symptoms of SPD, such as depression and anxiety. Antipsychotic drugs may also be used to treat delusional thinking and other psychotic symptoms.

Recovery and Prognosis of Schizotypal Personality Disorder

The outlook for individuals with SPD is relatively positive if they are engaged with a qualified therapist and are willing to participate in treatment. However, the disorder often requires long-term treatment, and recovery can take time. Research suggests that people with SPD who have undergone psychotherapy may experience some relief from symptoms over time, though research is limited.


Schizotypal Personality Disorder is a complex disorder that can be diagnosed through psychological assessments, interviews with mental health professionals, and self-reporting of symptoms by the individual. The disorder can be challenging to treat because it requires long-term psychotherapy, with a focus on changing the individual’s perceptions of themselves and the world around them. With the proper treatment, people with SPD can improve their quality of life and enjoy meaningful relationships with others.
