BPD symptoms often decline with age, particularly after the late 30s and into the 40s, with many people experiencing significant improvement in emotional intensity, impulsivity, and self-harm, although core issues like identity and abandonment fears can persist, and effective treatment is key for positive long-term outcomes. While symptom severity lessens, it's a gradual process, and many adults achieve remission, especially with ongoing support.
People with Borderline Personality Disorder (BPD) "split" (use black-and-white thinking) as a defense mechanism to manage overwhelming, conflicting emotions, especially fear of abandonment, by seeing people or situations as entirely "good" or "bad" rather than integrating complex realities, providing temporary relief from intense anxiety and emotional pain. It's a way to simplify a confusing world and protect themselves from perceived threats, but it often leads to unstable relationships and self-image.
Why BPD Symptoms Peak in Early Adulthood. In the 20s, identity formation and independence conflict with emotional vulnerability. Research shows impulsivity and mood swings occur most frequently between the ages of 18-25.
Borderline personality disorder (BPD) is associated with suicidal behaviors and self-harm. Up to 10% of BPD patients will die by suicide.
If Borderline Personality Disorder (BPD) is left untreated, symptoms worsen, leading to severe emotional instability, chaotic relationships, chronic emptiness, and a significantly higher risk of self-harm and suicide, alongside developing co-occurring mental health issues like depression, anxiety, and substance abuse, severely impacting daily functioning and overall quality of life.
You might also experience BPD without having any history of traumatic or stressful life events. Or you might have had other types of difficult experiences. If you already experience some of these difficulties, then experiencing stress or trauma as an adult could make things worse.
To qualify for SSDI or SSI benefits based on BPD, an individual must meet the SSA's definition of disability, which requires: The inability to engage in substantial gainful activity (SGA) The inability to perform previous work or adjust to other work due to the medical condition.
Commonly-prescribed mood stabilizers and anticonvulsants for those with BPD include:
Regarding physical health comorbidity, there is evidence concluding that BPD increases the risk of cardiovascular disease and related risk factors (i.e., hypertension, obesity, and diabetes), arteriosclerosis, arthritis, and other chronic pain syndromes, as well as gastrointestinal, hepatic, and sexually transmitted ...
The "3 C's of BPD" typically refer to advice for loved ones of someone with Borderline Personality Disorder, reminding them: "I didn't cause it, I can't cure it, I can't control it," to help set boundaries and avoid taking on undue responsibility for the person's actions or illness. Another set of "C's" describes core BPD traits for individuals: Clinginess (fear of abandonment), Conflict (intense relationships/moods), and Confusion (unstable self-image).
Conclusions: Parental externalizing psychopathology and father's BPD traits contribute genetic risk for offspring BPD traits, but mothers' BPD traits and parents' poor parenting constitute environmental risks for the development of these offspring traits.
The first symptoms usually appear in childhood and adolescence, and the disorder is most pronounced in young adulthood between the ages of 20 and 30.
Don't…
Jobs that draw on empathy, communication, and understanding, traits often strengthened by lived experience with BPD, can also be deeply rewarding. Examples include: Teaching assistant or education support worker. Counsellor, peer support, or mental health worker.
Some couples stay together for years, while others find the relationship too volatile to sustain. The BPD relationship cycle is a recurring sequence of emotional highs and lows that can repeat many times unless both partners seek support.
Patients with BPD showed significantly reduced volumes of both brain structures (left hemisphere hippocampus reduced 15.7%, right hemisphere hippocampus reduced 15.8%, left hemisphere amygdala reduced 7.9% and right hemisphere amygdala reduced 7.5%).
Patients with borderline personality disorder (BPD) are at high risk for early death from suicide and other causes, according to a study published in the Journal of Clinical Psychiatry.
How can I help myself in the longer term?
BPD patients, especially those that do not recover, are at elevated risk of premature death, due to suicide or other causes [50], related to an unhealthy and sometimes reckless lifestyle [51].
A “Favorite Person” is someone with whom a person with BPD forms an intense emotional attachment. This relationship is often marked by a combination of deep admiration, dependence and fear of abandonment. The FP becomes a central figure in the individual's life, often absorbing much of their emotional energy and focus.
Objectively measured sleep continuity is also disturbed in BPD, with patients having longer sleep onset latency and wakefulness after sleep onset, more awakenings, shorter total sleep time, and lower sleep efficiency than healthy controls [15,28].
But there are lots of positive things you can do to support them:
National Disability Insurance Scheme
Some people with BPD may meet the criteria for the NDIS, in particular those who have co-existing mental and physical health diagnoses. It is possible for people to recover from BPD however, and to go onto the NDIS, it is required you have a permanent disability.
Fear of Abandonment & Being Alone
For many with BPD, the fear of abandonment represents one of the most challenging aspects of living alone. This core symptom can trigger intense emotional responses when physically separated from others for extended periods.
Some common types of delusions that may occur in individuals with BPD include: Persecutory delusions: Believing that one is being mistreated, harassed, or conspired against by others.
