10 Types of Personality Disorders and Their Symptoms

We’ve all heard about personality disorders, but what do they actually mean and how many different types are there?

What is a personality disorder?

We all have our own unique way of thinking, feeling, behaving, and reacting. This all goes into making up our personality. A personality disorder is an ailment that affects these very things that make us into the people that we are.

Personality disorders, therefore, affect our way of thinking, feeling, behaving, and reacting. They can cause problems with day-to-day life and have long-term effects.

They affect our relationships with significant others such as family and friends, and we might find it difficult to maintain employment.

The symptoms of personality disorders

It is generally accepted that you could be diagnosed with a personality disorder if you display all three of the following:

1. Your feelings, thoughts, and behaviours cause you or others significant problems in daily life.
2. Your feelings, thoughts, and behaviours cause significant problems across different aspects of your life.
3. These problems have continued for a long time.

There are ten different types of personality disorders which can be grouped into three broad clusters – A, B, or C:

Cluster A

Anyone displaying a Cluster A personality disorder would be suspicious about others and show odd and eccentric behaviour bordering on paranoia.

Cluster B
