BPD has affected the lives of millions but there are millions more who are undiagnosed because they don't understand what could be causing their symptoms. While the causes of Borderline Personality Disorder are not definitive, many mental health professionals believe there are triggers, predetermined reasons, and factors that can cause BPD:
Genetics. Many times a person who suffers from a mental illness has had someone in their family (mother, father, grandparent or sibling) who suffered or suffers from a mental illness. BPD is no exception. You can receive traits of a mental illness just like you can receive traits of cancer, sickle cell anemia, and other health related issues. If you know that your family has a history of mental illness, even moments of long-term sadness or irrational thinking, then there is a possibility that you or someone in your immediate family can suffer from a mental condition like BPD.
Environmental Factors. Yes, your environment can change your mental state. If you are the victim of violence, abuse, or substance abuse, then you may have a slightly higher chance of developing BPD. You can also develop BPD if you experienced an abrupt or sudden loss of a parent, loved one or caregiver. Therefore, watching and being actively involved in traumatic situations in your personal life can ultimately have a great impact on your mental well-being.
Brain Abnormalities. Your brain can have a condition where the proper amount of hormones is not released to and through the brain. Basically your brain is not receiving enough serotonins; therefore creating problems in regards to making rational decisions. The chances of experiencing BPD only increases if you experienced a tumor, brain trauma or even brain surgery.
Borderline personality disorder is NOT acting out. It is a severe mental illness which can lead to severe depression, substance abuse, anxiety, eating disorder, unplanned pregnancies, deviant sexual behavior and/or other detrimental behaviors. Your environment can impact your mental health, as well as having a family history of mental illness and there is a slight chance that a trauma to your brain can cause BPD. Either way it is important that if you are not feeling "normal" then you need to get help today!
