Symptoms and Causes of Personality Disorders
Discover the types, causes, and symptoms of personality disorder and where to seek treatment in this comprehensive article.
Personality is how people think, feel, and behave, distinguishing them from others. An individual's personality tends to remain consistent throughout time. Experiences, environment (e.g., surroundings, life events), and genetic qualities all have an impact on personality.
Personality disorders can greatly alter and change a person’s personality in ways that do not align with standard, recognizable behaviors.
What Is a Personality Disorder?
It is a style of thinking, feeling, and acting that deviates from cultural standards, causes discomfort, interferes with functioning, and persists over time. Personality disorders are classified into ten separate disorders and can be chronic if not treated. They can have an impact on at least two of these areas:
Multiple Personality Disorder
Now called dissociative identity disorder (DID), multiple personality disorder is characterized by having two or more distinct identities. Both personalities cannot control the mind and body at once. Each identity has its own history, characteristics, preferences, and dislikes. DID can cause hallucinations and memory gaps.
Dissociative disorders are rare, occurring in 1% to 5% of the population worldwide, and severe cases occurring in 1% to 1.5% of the population.1

There are ten types of personality disorders grouped into three categories, known as clusters, based on overall characteristics and symptoms. Many who suffer from one disorder also show symptoms of at least one other type. A condition does not have to display all of the mentioned signs and symptoms before determining a diagnosis.
Various types of personality disorders will be detailed below.

The causes and risk factors associated with personality disorders will be discussed further below.
Genetics
Research suggests that specific genes are responsible for personality disorders. Particularly, genes linked to aggression, anger, and fear are deemed to play a vital role in the development of these disorders.
Brain Function
Variations and differences in brain structure and chemistry have been identified as causes of personality disorder. They have been proven to affect personality and hormone imbalances.
Trauma
One study has found a significant connection between traumatic experiences and personality disorders. Researchers discovered that BPD was present in patients who reported the highest rate of trauma, especially childhood sexual abuse, the youngest age of traumatic exposure, and the highest rate of posttraumtic stress disorder (PTSD). In addition, more severe personality disorders were linked to higher rates of physical assault and multiple types of trauma.3
Abuse
Research suggests that abuse, specifically verbal abuse, experienced during childhood significantly impacts the chance of developing a personality disorder. One study found that children who were verbally abused are three times more likely to develop BPD, narcissistic personality disorder, obsessive-compulsive personality disorder, or paranoid personality disorder as adults.4
Environmental, Cultural, and Social Factors
Environmental, social, and cultural variables can affect the development of personality disorders.
Each personality disorder category has unique indicators and symptoms. Nonetheless, personality disorders generally involve the following:
Relationships
Because of their problematic beliefs, thought processes, and actions, people with personality disorders find it difficult to build deep and peaceful relationships with others. Emotional disconnect, lack of empathy or regard for others, and extreme demand for attention and care are all characteristics that impact their ability to form healthy relationships.
Identity
Individuals with personality disorders usually lack a clear image of themselves and struggle with their identity. They may commonly change or alter their personality or identity depending on the people around them or their environment. Their self-esteem levels are usually exaggerated, either high or low.
