What is personality change due to another medical condition?
Personality change due to another medical condition is not really a form of mental disorder that is developed across the life span. Rather, it is an output or effect of another medical condition. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), (published by The American Psychiatric Association), a person with personality change due to another medical condition must have a persistent personality disturbance. Furthermore, there must be evidence that the change in personality is really the direct effect of another medical condition.
Therefore, a person can only be diagnosed with personality change due to another medical condition if the following criteria are satisfied:
- There must be a significant change in a personality pattern
- Evidence is sufficient that a change is the result of another medical condition
- The disturbance can not be linked to another personality disorders
- The disturbance does not occur during the delirium
- A person is impaired in many areas of his/her functioning
What are the common manifestations of this condition?
Symptoms of Personality Change Due to Another Medical Condition
People with this condition may experience or show the following characteristics:
- Difficulty in controlling impulsive behavior
- Unreasonably aggressive
There are many factors that could cause personality change due to another medical condition. It may include neurological and medical conditions such as head trauma, cerebrovascular disease, epilepsy, infection in the central nervous system, etc.
The DSM-5 states that a person’s clinical presentation may depend on the localization of the pathological process.
For example, injury to the frontal lobes may yield symptoms such as lack of judgment or foresight, facetiousness, disinhibition, and euphoria. Right hemisphere strokes have often been shown to evoke personality changes in association with unilateral spatial neglect, anosognosia (i.e., inability of the individual to recognize a bodily or functional deficit, such as the existence of hemiparesis), motor impersistence, and other neurological deficits.
