Schizotypal Personality Disorder: Symptoms, Causes, and Treatment

There are many misconceptions about STPD, including that people with the condition are delusional or antisocial, but the symptoms of this condition stem from the way someone with this condition perceives and processes the world.

Some experts believe STPD and schizophrenia are on the same spectrum, but STPD is viewed as less severe. These two conditions have some overlapping syptoms, but they are two separate conditions.

People with schizophrenia experience psychosis and struggle to manage and interpret reality. While people with STPD can have brief periods of psychosis where they experience hallucinations or delusions, they are not as intense, less frequent, and do not occur as often. People with STPD typically do not involve full-blown delusions or hallucinations. They can usually understand that their ideas differ from reality, but those with schizophrenia generally cannot be persuaded that their delusions are not real.

STPD may be caused by a combination of factors. Medical conditions that damage neurons, like head trauma, epilepsy, or multiple sclerosis, are often associated with personality disorders. It is also thought to have a genetic component as it is more common in people who have a family history of other personality disorders or schizophrenia.

Some research indicates that brain abnormalities and neurotransmitters like dopamine can also play a role, but more research is needed.

Symptoms of STPD can include the following:

• Appearing odd or eccentric
• Having magical thinking and odd beliefs
• Believing in special powers, like telepathy
• Being suspicious or paranoid
• Having an inappropriate or flat affect
• Lacking close friends and confidants
• Feeling discomfort in social settings
• Interpreting innocent, harmless events as personal and offensive
• Exhibiting odd manners of speaking

Only a qualified mental health professional can diagnose STPD, and it often includes interviews, questionnaires, and observational assessments. In the DSM-5, the diagnostic criteria for STPD has two main criteria.

Criterion A includes a requirement for moderate or greater impairment in personality functioning. To meet this criterion, someone must demonstrate challenges in two of the following areas:

• Identity: Distorted self-concept, confused boundaries between self and others, an emotional expression often not congruent with the context or internal experience
• Self-direction: Unrealistic or incoherent goals with no clear set of internal standards
• Empathy: Pronounced difficulty understanding the impact of one's behavior on others or frequent misinterpretations of the motivations and behavior of others
• Intimacy: Marked impairments in developing close relationships associated with mistrust and anxiety

Criterion B specifies pathological personality traits related to STPD; diagnosis requires four or more of the following:

• Cognitive and perceptual dysregulation: Having odd, unusual thought processes; using vague, metaphorical, circumstantial, or overelaborate speech; experiencing odd sensations in various senses
• Unusual beliefs and experiences: Having thoughts and views of reality that others view as bizarre or idiosyncratic; having unusual experiences of reality
• Eccentricity: Engaging in odd, unusual, or bizarre behavior or appearance; saying unusual or inappropriate things
• Restricted affectivity: Experiencing minimal reaction to emotional situations; having restrained emotional experiences and expressions; being cold or indifferent
• Withdrawal: Preferring to be alone, avoiding or not initiating social content, being reserved in social situations
• Suspiciousness: Expecting or being sensitive to signs of harm or ill-intent from others; doubting the loyalty of others; feeling persecuted

This condition is challenging to treat, and it is unlikely to improve on its own. There are several treatment options available for STPD.

Talk therapy, particularly cognitive-behavioral therapy (CBT), is commonly used to help people with STPD to help recognize and manage symptoms. However, this approach to treatment has not been well-studied. Therapy can also help people with this condition improve their relationships and navigate social situations.

There are no specific medications used to treat STPD, though antidepressants and antipsychotics can help manage specific symptoms, particularly paranoid ideation.

Learning coping strategies for living with STPD can raise self-confidence and promote better coping skills.

People with STPD may see improvement in their symptoms if they engage with family and friends in social situations, maintain a healthy routine, engage in self-care, and have a sense of accomplishment at work or school.

STPD can profoundly impact relationships, often creating barriers to connection and understanding. Individuals with STPD may find social interactions uncomfortable, not because they lack the ability to engage, but because they often feel out of place or disconnected.

Their eccentric behaviors and unconventional thought patterns can lead to misunderstandings or misjudgments from others, which only deepens their sense of isolation. Despite their anxiety in social settings, many people with STPD may still desire relationships and feel dissatisfaction with their social lives.

For loved ones, offering support with patience and fostering open, non-judgmental communication can make a significant difference in building trust and connection.

If you are experiencing symptoms of STPD or any other mental health condition that significantly affects your daily life or relationships or causes persistent distress, it can be beneficial to seek professional help. Consult with a mental health professional who has experience with personality disorders to ensure an accurate diagnosis and appropriate treatment.

People with STPD are at risk for a variety of other mental health conditions, including anxiety, depression, substance misuse, and self-harm, so it can be beneficial to begin treatment as soon as possible.

People with STPD are often misunderstood. To help reduce the stigma about this and both mental health conditions, it is vital for loved ones to offer support and empathy.

With appropriate treatment and support from friends, family, and qualified mental health professionals, people with this personality disorder can improve their social functioning and lead more fulfilling lives.
