Key Takeaways
STPD is a mental health condition characterized by odd or unusual thoughts, perceptions, and behaviors. These symptoms can make it difficult for a person to form relationships and function effectively in daily life.
Some of the most common signs of STPD include significant discomfort in social settings, an eccentric or unusual appearance or behaviors, and a tendency to perceive special or hidden messages in everyday events. These can sometimes be mistaken for symptoms of other mental health conditions, which can complicate diagnosis.
While there’s no cure for STPD, its symptoms can be managed with the right support. This usually includes therapies like cognitive behavioral therapy (CBT) and medication.
Schizotypal personality disorder (STPD) is characterized by a pattern of unusual thoughts, behaviors, and appearance and difficulty forming and maintaining interpersonal relationships. While there’s limited data on the prevalence of STPD, some research shows that it may affect approximately 4% of people worldwide. STPD appears to disproportionately affect people experiencing housing instability.
Although STPD is a distinct diagnosis, mental health professionals consider it part of the broader schizophrenia spectrum. This is because STPD and schizophrenia share some similar features, including unusual beliefs and perceptual experiences. However, most people with STPD don’t go on to develop schizophrenia.
Signs and symptoms of STPD
To be diagnosed with STPD, a person must display chronic, intense discomfort in social situations and difficulty forming close relationships. They must also experience eccentric behavior or thinking.
Some of the most common signs of STPD include:
Having unusual or odd beliefs, fantasies, preoccupations, or behaviors (like believing they have special abilities or can communicate with supernatural entities)
Having unusual or odd appearance, speech, or mannerisms
Experiencing paranoia or suspiciousness (like thinking they’re being surveilled without evidence)
Living with co-occurring mental health conditions, like depression, anxiety, borderline personality disorder (BPD), or substance use disorder (SUD)
Having few friends or close relationships
Expressing feelings in inappropriate or constricted ways
Feeling extreme discomfort in social situations
Keep in mind that almost anyone can have these experiences. For example, you might like to dress in unique ways, have a narrow set of interests, or have trouble making friends. This doesn’t necessarily mean you have a mental health condition.
To be diagnosed with STPD, on top of the symptoms mentioned above, a person must experience at least five of the following symptoms by early adulthood:
Believing that everyday occurrences have special personal significance (sometimes referred to as having ideas of reference)
Thinking they have special abilities or magical powers
Reporting unusual and unfounded experiences (like hearing voices or unexplained sounds)
Speaking in strange, overly elaborate, or metaphorical language
Experiencing frequent suspiciousness or paranoia
Having few close friends or acquaintances outside of immediate family
Showing limited or unusual facial expressions
Experiencing significant social anxiety linked to paranoia rather (than self-judgment)
Having strange, eccentric, or odd appearance and/or behaviors
Can STPD symptoms overlap with other conditions?
Sometimes, STPD symptoms can overlap with symptoms of other mental health conditions. For example, schizophrenia, delusional disorder, and mood disorders with psychotic features can all involve hallucinations (seeing or hearing things that aren’t there) and delusions (believing things that are qualitatively false).
On the surface, these symptoms can look similar to the odd or eccentric beliefs that accompany STPD. However, there’s an important distinction between STPD and these conditions: People with STPD have ideas of reference. This means they interpret real events as having special meaning for them. However, they don’t typically experience delusions or hallucinations that aren’t based in reality.
In addition, STPD can be mistaken for autism spectrum disorder (ASD). This is because both conditions can create interpersonal difficulties, communication challenges, unusual behaviors, and problems with self-regulation. However, symptoms like magical thinking and ideas of reference are more common with STPD than with ASD.

What causes schizotypal personality disorder?
STPD is a complex condition that hasn’t been studied as frequently as other personality disorders. While the exact cause of STPD isn’t known, it likely has to do with a combination of the following:
Genetics: Having a first-degree relative with STPD or related conditions, like schizophrenia, may make you more likely to develop the condition.
Environment: Experiencing abuse, neglect, or other adverse childhood experiences may increase your risk of STPD.
Psychology: Your individual personality style and the way you respond to stress and manage relationships could contribute to the onset of STPD.
How severe is schizotypal personality disorder?
Left untreated, STPD can negatively affect many aspects of a person’s life, including education, employment, and relationships. Some people may have trouble finishing school, keeping a job, or building a strong support network without treatment and ongoing support. In rare cases, STPD can progress to schizophrenia or another psychotic disorder, although most people with STPD don’t develop these conditions.
Common misconceptions about STPD
There are several misconceptions about STPD, including the harmful stereotype that people with STPD are “dangerous.” In reality, most people with STPD aren’t violent. The condition mainly involves unusual thoughts, discomfort in social situations, and difficulty forming close relationships — not a desire to harm others.
This stereotype can make it harder for people with STPD to seek help, talk openly about their symptoms, or feel accepted in their communities. Understanding the condition more accurately can reduce stigma and encourage people to get the support they deserve.
What treatment options are there for STPD?
If you think you may have schizotypal personality disorder, a helpful next step is to seek an evaluation from a licensed mental health professional, like a psychologist or psychiatrist. They can assess your symptoms, rule out other conditions, and help you decide what type of support might be most useful. Your primary care provider can also offer referrals if you’re unsure where to start.
Most people with STPD need ongoing care to manage their mental health and overall well-being. This usually involves a combination of medication and therapy. While there are no medications approved to treat STPD specifically, there are medications that can increase mental stability or address symptoms of co-occurring conditions, like depression. It’s important to work with your provider to determine if medication is right for your unique needs.
Similarly, there aren’t any STPD-specific talk therapies. But research shows that approaches like cognitive behavioral therapy (CBT) can be helpful for people living with personality disorders. In the case of STPD, CBT can help people improve social skills and learn to form meaningful connections when delivered within the context of a safe and supportive therapeutic relationship.
Clinician's take
I encourage clients to shift from viewing their symptoms as something inherently wrong with them to understanding that these traits are part of a condition that can be managed with the right support and strategies.
