Although the term emotional lability suggests rapid changes between depression and elation, the mood swings in people with this condition actually fluctuate more frequently between anger and anxiety and between depression and anxiety.A cycle often begins in which people with BPD feel emotional pain, engage in impulsive behavior to relieve that pain, feel shame and guilt over their actions, feel emotional pain from the shame and guilt, and then experience stronger urges to engage in impulsive behavior to relieve the new pain.
Many people with BPD are able to work if they find appropriate jobs and their condition is not too severe.
People with BPD may be found to have a disability in the workplace, if the condition is severe enough that the behaviors of sabotaging relationships, engaging in risky behaviors, or intense anger prevent the person from functioning in their professional role.
These same researchers had earlier concluded in a previous study that 42 percent of variation in BPD features was attributable to genetic influences and 58 percent was attributable to environmental influences.
Genes under investigation as of 2012 include the 7-repeat polymorphism of the dopamine D4 receptor (DRD4) on chromosome 11, which has been linked to disorganized attachment, whilst the combined effect of the 7-repeat polymorphism and the 10/10 dopamine transporter (DAT) genotype has been linked to abnormalities in inhibitory control, both noted features of BPD.
They are often unsure about their long-term goals for relationships and jobs.
