Eccentric personality disorder


Schizotypal personality disorder - Symptoms and causes

Overview

People with schizotypal personality disorder are often described as odd or eccentric and usually have few, if any, close relationships. They generally don't understand how relationships form or the impact of their behavior on others. They may also misinterpret others' motivations and behaviors and develop significant distrust of others.

These problems may lead to severe anxiety and a tendency to avoid social situations, as the person with schizotypal personality disorder tends to hold peculiar beliefs and may have difficulty with responding appropriately to social cues.

Schizotypal personality disorder typically is diagnosed in early adulthood and is likely to endure across the lifespan, though treatment, such as medications and therapy, can improve symptoms.

Symptoms

Schizotypal personality disorder typically includes five or more of these signs and symptoms:

  • Being a loner and lacking close friends outside of the immediate family
  • Flat emotions or limited or inappropriate emotional responses
  • Persistent and excessive social anxiety
  • Incorrect interpretation of events, such as a feeling that something that is actually harmless or inoffensive has a direct personal meaning
  • Peculiar, eccentric or unusual thinking, beliefs or mannerisms
  • Suspicious or paranoid thoughts and constant doubts about the loyalty of others
  • Belief in special powers, such as mental telepathy or superstitions
  • Unusual perceptions, such as sensing an absent person's presence or having illusions
  • Dressing in peculiar ways, such as appearing unkempt or wearing oddly matched clothes
  • Peculiar style of speech, such as vague or unusual patterns of speaking, or rambling oddly during conversations

Signs and symptoms of schizotypal personality disorder, such as increased interest in solitary activities or a high level of social anxiety, may be seen in the teen years. The child may be an underperformer in school or appear socially out of step with peers, which may result in teasing or bullying.

Schizotypal personality disorder vs. schizophrenia

Schizotypal personality disorder can easily be confused with schizophrenia, a severe mental illness in which people lose contact with reality (psychosis). While people with schizotypal personality disorder may experience brief psychotic episodes with delusions or hallucinations, the episodes are not as frequent, prolonged or intense as in schizophrenia.

Another key distinction is that people with schizotypal personality disorder usually can be made aware of the difference between their distorted ideas and reality. Those with schizophrenia generally can't be swayed away from their delusions.

Despite the differences, people with schizotypal personality disorder can benefit from treatments similar to those used for schizophrenia. Schizotypal personality disorder is sometimes considered to be on a spectrum with schizophrenia, with schizotypal personality disorder viewed as less severe.

When to see a doctor

People with schizotypal personality disorder are likely to seek help only at the urging of friends or family members. Or people with schizotypal personality disorder may seek help for another problem such as depression. If you suspect that a friend or family member may have the disorder, you might gently suggest that the person seek medical attention, starting with a primary care doctor or mental health professional.

If you need immediate help

If you're concerned that you might harm yourself or someone else, go to an emergency room or call 911 or your local emergency number immediately. Or call a suicide hotline number. In the U.S., call the National Suicide Prevention Lifeline at 1-800-273-TALK (1-800-273-8255) or use its webchat at suicidepreventionlifeline.org/chat.

Causes

Personality is the combination of thoughts, emotions and behaviors that makes you unique. It's the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, shaped through an interaction of inherited tendencies and environmental factors.

In normal development, children learn over time to appropriately interact with others, to interpret social cues, and to respond to social situations appropriately and with flexibility. What exactly goes wrong for a person with schizotypal personality disorder isn't known for certain, but it's likely that changes in the way the brain functions, genetics, environmental influences and learned behaviors may play a role.

Risk factors

Your risk of schizotypal personality disorder may be greater if you have a relative who has schizophrenia or another psychotic disorder.

Complications

People with schizotypal personality disorder are at an increased risk of:

  • Depression
  • Anxiety
  • Other personality disorders
  • Schizophrenia
  • Temporary psychotic episodes, usually in response to stress
  • Problems with alcohol or drugs
  • Suicide attempts
  • Work, school, relationship and social problems

Personality disorders - Symptoms and causes

Overview

A personality disorder is a type of mental disorder in which you have a rigid and unhealthy pattern of thinking, functioning and behaving. A person with a personality disorder has trouble perceiving and relating to situations and people. This causes significant problems and limitations in relationships, social activities, work and school.

In some cases, you may not realize that you have a personality disorder because your way of thinking and behaving seems natural to you. And you may blame others for the challenges you face.

Personality disorders usually begin in the teenage years or early adulthood. There are many types of personality disorders. Some types may become less obvious throughout middle age.

Causes

Personality is the combination of thoughts, emotions and behaviors that makes you unique. It's the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, shaped through an interaction of:

  • Your genes. Certain personality traits may be passed on to you by your parents through inherited genes. These traits are sometimes called your temperament.
  • Your environment. This involves the surroundings you grew up in, events that occurred, and relationships with family members and others.

Personality disorders are thought to be caused by a combination of these genetic and environmental influences. Your genes may make you vulnerable to developing a personality disorder, and a life situation may trigger the actual development.

Risk factors

Although the precise cause of personality disorders is not known, certain factors seem to increase the risk of developing or triggering personality disorders, including:

  • Family history of personality disorders or other mental illness
  • Abusive, unstable or chaotic family life during childhood
  • Being diagnosed with childhood conduct disorder
  • Variations in brain chemistry and structure

Complications

Personality disorders can significantly disrupt the lives of both the affected person and those who care about that person. Personality disorders may cause problems with relationships, work or school, and can lead to social isolation or alcohol or drug abuse.

What is eccentricity and when does it turn into a mental disorder

April 14 Likbez Health

Perhaps a disease is hidden behind the defiant behavior.

What is eccentricity

According to the "Big Dictionary of the Russian Language", eccentricity is a strange, defiantly unusual behavior. It can be expressed in deliberately bright clothes that do not correspond to the moment. Or in non-standard habits regarding communication with other people. For example, an eccentric person speaks too loudly or manneredly, does it in verse, openly classifies interlocutors according to the types invented by him (“You are a gentle cat, and he is a watchdog!”).

In the mass understanding, an eccentric person is an extraordinary, outstanding personality. It is no coincidence that such behavior is often associated with talented and even brilliant people. For example, there are legends about the eccentricity of Salvador Dali. Or Albert Einstein. Or, say, Winston Churchill.

In general, being eccentric, “not like everyone else”, is even fashionable. But there is a line beyond which bizarre behavior turns from a way of self-expression into an unhealthy phenomenon.

When eccentricity becomes a mental disorder

Eccentric personality disorder is included in the International Classification of Diseases (ICD-10). It's just that it's not described in enough detail.

However, there is a whole class of much more studied eccentric disorders - the so-called cluster A. It includes three types of disorders that are characterized by pronounced oddities in behavior:

  1. Paranoid.
  2. Schizoid.
  3. Schizotypal.

The first disease usually manifests anxiety, suspicion, vindictiveness, and the second - isolation, emotional coldness. Demonstrative bizarre behavior or appearance is unique to schizotypal disorder.

Experts from the American research organization Mayo Clinic list 10 signs of this disorder. To suspect a personality disorder, five of them are enough:

  1. Defiant behavior that goes beyond the usual limits.
  2. Unusual appearance. Clothing may be dirty, and its elements may fundamentally not be combined with each other.
  3. A peculiar manner of speaking, which is hard not to notice during a conversation. For example, the voice may be too high or the person may sing the words.
  4. Belief in personal supernatural powers. For example, the patient sincerely believes that he can read the thoughts of others. Or communicate with the spirits of the dead. Or predict the future based on the sound of the wind and the movement of the stars.
  5. Experienced unusual sensations. A person may report feeling the presence of someone who is actually very far away. Or supposedly physically feels the approach of danger.
  6. Inability to adequately assess what is happening. Even minor events can be given great importance.
  7. Suspicion, constant doubts about the good intentions of others.
  8. Excessive and persistent social anxiety. The patient does not accept assessments from other people, because he believes that they cannot understand him.
  9. Inability to establish a long and trusting relationship with anyone. Friends are usually only among the closest relatives.
  10. Inappropriate reactions, coldness in communication. A person may not express emotions at all or react to what is happening inadequately. For example, laugh when you usually cry.

What are the causes of eccentric personality disorder

Most often, the disorder appears during adolescence or early adulthood. Where it comes from, doctors do not know for sure. It is assumed that genetics, the individual characteristics of the brain, the environment, and habits learned in childhood play a role.

What to do if you suspect eccentric personality disorder

This mental disorder can be corrected with psychotherapy or medications such as antidepressants.

The difficulty lies in the fact that “eccentrics”, as a rule, do not consider their behavior to require correction and are often not ready to turn to a psychotherapist. In this case, relatives or caring acquaintances are especially important. Their task is still to convince to consult a specialist.

The easiest way looks like this. A person with eccentric personality disorder regularly experiences disappointment in people, bouts of anxiety and even depression. It is at such moments that it is worth taking him by the hand and leading him to talk to a psychotherapist. The specialist will be able to establish the disorder based on the conversation and the symptoms that will be described. And then he will recommend to the person options for therapy that will help improve the condition.

By the way, one of the elements of psychocorrection is family and friendly support. It is easier for a person with eccentric disorder to live when he feels that he is loved and appreciated, supported during failures and rejoice at successes.

Specific personality disorders

Personality disorders are personality traits. They do not fit into the concepts of "disease", "disease" - it is impossible to say exactly when it all started, it is impossible to single out clear periods of exacerbations and recovery.

Personality disorder is a "hard character". You can smooth out its manifestations with the help of individual psychotherapy.

Symptoms of personality and behavioral disorders begin to appear in childhood and adolescence and may persist throughout life. It is difficult for such people to contact with others, they often behave inappropriately or generally prefer loneliness. Treatment by a psychotherapist can significantly improve the condition of people with a personality disorder and their loved ones, teaches them to interact with the world around them while maintaining a sense of comfort.

In the International Classification of Diseases (ICD-10), mental and behavioral disorders correspond to class V (F), codes F60-69.

There are the following types of personality disorders:

  • paranoid;
  • schizoid;
  • dissocial;
  • emotionally unstable;
  • border
  • hysterical;
  • anancaste;
  • anxious (avoidant, evading);
  • dependent personality type disorder.

More rare variants of personality and behavior disorders are eccentric, disinhibited, infantile, passive-aggressive, narcissistic. Mixed forms are possible.

Identification of personality and behavior disorders in adulthood

Personality and behavioral disorders are not diseases, but they seriously complicate the life of a person and his loved ones. Such people seek help because of a sense of emptiness and a sense of inferiority in life.

Important

Inadequate human behavior can be a manifestation of serious mental illness - depression, some forms of neurosis, or even schizophrenia. Differential diagnosis is carried out by a psychotherapist.

A psychotherapist is engaged in the diagnosis and treatment of personality disorders. A personality disorder is diagnosed if the following criteria are met:

  • signs of the disorder appeared in childhood or adolescence and persist throughout life;
  • it is difficult to distinguish clear periods of recovery and exacerbation;
  • the disorder adversely affects several areas of life - difficulties in work, communication, personal life;
  • stubbornness, often selfishness, desire for pleasure, inability to empathize (sympathy for others), lack of flexibility in communication;
  • pronounced internal distress of the personality - a feeling of tension and discomfort.

The listed signs should not be symptoms of another mental illness or a consequence of head injuries, operations, tumor or infectious lesions of the brain. Only when other causes are ruled out can one speak of personality disorders.

Personality disorder treatment

A personality disorder causes serious difficulties in communication, it is difficult to establish social connections and work, a feeling of internal imbalance and emptiness is characteristic. A “severe character” that interferes with life is also a mental disorder. Personality, character is very difficult to change, because they are formed in early childhood. But an experienced psychotherapist can handle this.

The specialist does not set the task of changing the patient's personality and redrawing his character, making him "correct". During the course of individual psychotherapy, he, together with the patient, identifies the difficulties that a person has when interacting with the outside world and their causes.
