Let’s define the difference between problems and disorders.
We all have problems: marital, financial, health, family, etc.
When you bring these problems with you into an injury, you complicate the course of recovery from the injury.
Concurrently, the injury complicates your ability to deal with these problems.
Some of us have disorders: bipolar disorder, addictive disorder, generalized anxiety disorder, etc.
These disorders do not naturally arise from an injury. Bipolar disorder is not caused by an injury any more than a personality disorder is caused by an injury. Many disorders arise from problems with brain chemistry. They have a biological basis.
Many people who, for example, have bipolar disorder do not know that their behavior is under the influence of an undiagnosed psychological disorder. This is why it is critically important to secure a complete history on a patient including health history of extended family, course of the patient’s developmental and educational background, and whether there have been periods of intense/unstable relationships.
If you mistakenly attribute and treat a longstanding, but previously undiagnosed, disorder as having arisen from injury, you will not be successful in treating the disorder or the injury.
