Borderline personality disorder is exactly what it sounds like – a disorder where the patient is unable to choose his “own” personality and in doing so, exhibits the traits and characteristics of multiple people, at different times, and in very difficult and sometimes violent or hostile situations. Borderline personality disorder can be very dangerous as many individuals who suffer from a disorder like this have shown to be somewhat violent and unpredictable, though that is not true of all people who suffer from the disorder.
Borderline personality disorder affects men more than women, typically, but it can affect all people from all walks of life. Those suffering from borderline personality disorder typically have no knowledge or recollection of their actions, and thus typically are unable to cure themselves, requiring therapy, medication, care and oversight from medical professionals to keep their issues in check and at hand.
Psychological and medical professionals are divided as to what causes borderline personality disorder, though most factions argue it is either genetic factors, or environmental factors – or a combination of both of the above. Genetic factors are said to be at play in that people who are diagnosed with borderline personality disorder and the tendencies related in their own lives are more likely to have children which also experience and suffer with borderline personality disorder.
Additionally, the environment someone is raised in can play a large role in the formation of borderline personality disorder, too. People who grow up in stressful or violent situations appear more likely to suffer from borderline personality disorder, possibly as a way to cope with and mentally escape their stressful or violent life situations and relinquish control of their personal problems.
The symptoms of borderline personality disorder are varied and different in each case, but generally speaking, those who suffer from borderline personality disorder will obviously suffer through competing personalities. That is, at one time they will behave in a certain manner and with certain character traits, and then seemingly in the span of one second, can distinctly switch characteristics to effectively become another person.
Additional symptoms of borderline personality disorder include the appearance of paranoia and mistrust in the patient who suffers from the disorder, as well as a conspiratorial, and sometimes violent outlook on life and interaction with others. Those suffering from borderline personality disorder often behave erratically, sometimes with no memory or recognition of their erratic behavior afterwards.
