F60-F69: Disorders of adult personality and behaviour

F62: Enduring personality changes, not attributable to brain damage and disease

Enduring personality changes refer to a group of conditions where a person's patterns of perceiving, relating to, and thinking about the environment and oneself change over the long term, not as a result of brain damage or disease. These changes are typically caused by highly stressful or traumatic experiences, including cases of prolonged exposure to life-threatening events or extreme violence. As a result, the person starts displaying personality traits that differ considerably from their previous character. Common symptoms may include alterations in belief systems, changes in emotional responses, and experiencing difficulty forming close relationships. It's important to note that these changes persist over a prolonged period and may lead to significant distress or impairment in social and occupational functions.
