F62: Enduring personality changes, not attributable to brain damage and disease
F62.8: Other enduring personality changes
Enduring personality changes, as signified by the ICD-10 code F62.8, are shifts in an individual's established patterns of behavior, thinking, and feeling that persist over a long period of time. There can be various causes for these changes, but they often occur after significant life events or stressful periods. Personality changes can include alterations in mood such as increased anxiety or irritability, fluctuations in energy levels, or changes in social interactions ranging from withdrawal to excessive sociability. Some individuals may also exhibit altered perceptions or beliefs. It's also important to note that these changes are not a normal part of aging or a direct result of substance abuse or a medical condition. They are, however, significant enough to cause distress or impairment in social, occupational, or other important areas of functioning.
