Causes

Personality is the combination of thoughts, emotions and behaviors that makes you unique. It's the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, shaped through an interaction of inherited tendencies and environmental factors.

In normal development, children learn over time to accurately interpret social cues and respond appropriately. What causes the development of schizoid personality disorder is unknown, although a combination of genetic and environmental factors, particularly in early childhood, may play a role in developing the disorder.
