What is the Common Factor in All Personality Disorders?

Your personality is a combination of your thoughts, behavior, and emotions. Each one of you has a different personality. Hence, your way of talking to people, reacting to situations, and thinking about certain things often differ from other people.

Some are shy. Some are very outspoken. Some prefer to be alone while others love to socialize. We have some preset notions for distinguishing between normal and not-so-normal personality traits.

A person who is kind, joyful, and communicates well is said to have a likable personality. On the other hand, a person who appears rude avoids interacting with people, and prefers to be alone is thought to have an unlikeable personality. This person might have a condition that makes him/her behave in a certain manner and prevents from having a normal healthy personality. Such a condition is called personality disorder.

Let’s shed some more light on the types of personality disorders and the common factors in all of them.

What are Personality Disorders?

Humans are vulnerable to multiple mental health problems, personality disorders are one of them.

A person with a personality disorder exhibits a pattern of behavior and thoughts different from what is considered normal. It is not only abnormal but also unhealthy, affecting a person’s well-being in multiple aspects like career, relationships, and social circle.

Causes of Personality Disorders

From genetics to environmental factors, multiple causes contribute to the development of personality disorders in individuals.

Here’s an evidence-backed walkthrough of each cause.

Childhood trauma

Children who have experienced traumatic incidents are more susceptible to personality disorders, finds a study. Instances of childhood abuse and witnessing domestic violence are linked with the development of schizotypal personality.

Verbal abuse

A study finds a correlation between enduring verbal abuse and suffering with personality disorders. According to this, children who were verbally abused had a 3 times greater likelihood of developing borderline, paranoid, or obsessive-compulsive personality disorder, in later stages of life.

Genetics

Recent studies have shown that genetic factors influence the development of personality disorders. If a person has parents or siblings with a history of personality disorders, there’s a 30% to 80% probability of the person inheriting the disorder. Exposure to abusive and stressful environments can further increase the risk.

Brain abnormalities

Neuroimaging studies have found marked changes in the brain of a person with schizotypal personality disorder. The major affected regions were the amygdala, prefrontal cortex, basal ganglia, thalamus, and corpus callosum. Lower metabolism and decreased activation in these parts of the brain are linked to borderline personality disorder, according to another research.

What is the Common Factor in All Personality Disorders?

Several studies attempted to find the answer to — what is the common factor in all personality disorders?

It turns out, there isn’t any single common factor encompassing all personality disorders.

Instead, the following 4 factors are found to be common in all types of personality disorders.

1.  Negative feelings overpower

People with personality disorders experience increased occurrence and intensity of negative emotions, finds a study after assessing behavior of 281 participants.

When you’re diagnosed with PD, It’s hard to get happiness and pleasure from most of the things you do. As a result, you become short-tempered, get triggered by trivial things, develop a sense of envy towards people, and, in some cases, build a negative image of yourself, too.

2.  Unstable emotions

You either feel no emotions or too many emotions at once. Your feelings keep swinging between the two extremes.

Either way, you seem to have no control over your emotions. This can even take you into a state of committing self-harming and violent activities, confirms a study.

3.  Choosing isolation over interaction

Being among people, especially for too long, makes you anxious. Hence, you prefer staying indoors, spending time alone, and making choices that limit interacting with people.

You also find it hard to relate to people or communicate clearly with them. This affects both your personal and professional relationships.

4.  Disconnect from reality

One of the common factors of suffering from personality disorder is being delusional. You see and hear things that aren’t real but appear realistic to you.

As per the 2015 research, 2 out of 3 people with BPD experience dissociative state symptoms. A state where you start having false perceptions of your reality. This happens for a certain period, after which you return to your true surroundings but are unable to remember whatever occurred during that period. These states keep occurring over and over again.

Conclusion

Personality disorders can be of various types. They are genetically driven, a result of a person’s early-life experiences, physiological changes, or combined consequences of all three. Often, these have adverse effects on an individual’s life, such as:

  • Poor relationships
  • Professional challenges
  • Self-destructing actions
  • Regular anxiety and stress
  • Inability to function optimally

The bright side is, with proper guidance and diagnosis, such effects can be averted and the situation can be improved.

Therefore, it’s important to observe relevant symptoms in your friends and family. The earlier you seek help, the better it is.
