Personality Disorders - Types, Symptoms, Clusters, Nursing Care & Treatment

Personality shapes the way people think, feel, and behave in the world. It is influenced by genetics, environment, upbringing, and life experiences. However, when patterns of thought and behavior become rigid, unhealthy, and disruptive to relationships or daily functioning, they may be classified as personality disorders.

Personality disorders are long-term mental health conditions that affect how individuals perceive themselves and others. Unlike short-term stress responses, these disorders are enduring and usually start in adolescence or early adulthood. They can cause significant distress, impair social and occupational functioning, and increase vulnerability to other mental health issues such as depression, anxiety, and substance use.

In this article, we will explore:

• The three main clusters of personality disorders.
• The specific disorders within each cluster.
• Symptoms and behavioral patterns.
• Nursing care approaches for patients.
• Treatment options including medications and therapy.

Set limits and consistency: Prevent manipulation and maintain structure.

Promote client empowerment: Allow choices to enhance their sense of control.

Antidepressants – For depression, low mood, and anxiety.
