Guide To The Major Types Of Personality Disorders
Obsessive-Compulsive Personality Disorder

Obsessive-compulsive personality disorder is one that involves an extreme need for neatness and order. Patients deal with extreme perfectionism. They will often feel an intense desire to impose their incredibly high standards on their surrounding environment. Patients often find it challenging to express how they feel and have trouble maintaining close relationships. They will often experience social isolation and anxiety that appears with depression.
These patients will typically feel angry, indignant, and righteous about their need for perfection. This is what differentiates obsessive-compulsive personality disorder from OCD, though patients will display OCD symptoms. Those with the personality disorder do not believe there is anything wrong with their behavior or thinking. In other words, they think they are right, and everyone else is wrong. The precise cause is not known. However, many believe genetics and childhood experiences are significant factors.

Schizoid Personality Disorder

Schizoid personality disorder is not a common condition. It involves patients avoiding social activities and exhibiting limited emotional expressions. Symptoms include a preference for being alone, not wanting close relationships, and appearing emotionally cold. The lack of displayed emotion often makes it seem as if patients do not care about others. Symptoms appear by early adulthood. However, they can appear in an individual's childhood as well. Patients can struggle at school and work, unless they work alone.
Research indicates that genetics and environmental factors are significant in the development of this condition. However, the cause itself is unclear. One risk factor, though, is an individual having a neglectful or cold parent during their childhood. Another risk factor is having a parent with this condition, schizophrenia, or schizotypal personality disorder.
