Personality affects how each of us thinks, feels, and relates to others. For some people, long-standing patterns of thinking and behaving become rigid and cause significant distress — for themselves and for the people close to them.
This article explains what personality disorders are, including borderline and narcissistic personality disorder, and how they are treated. For an overview of care, see the psychiatric services page.
What are personality disorders?
Personality disorders involve long-lasting, rigid patterns of thinking, functioning, and behaving. People with a personality disorder often struggle to relate to situations and people.
These patterns are not a choice or a simple matter of personality style. They are recognized mental health conditions that cause real distress and affect relationships, work, and daily life. They usually begin in adolescence or early adulthood and are experienced as deeply ingrained parts of how a person operates.
Borderline Personality Disorder (BPD)
Borderline Personality Disorder is characterized by:
- Intense emotional instability — strong emotions that shift rapidly and are hard to regulate
- Fear of abandonment — intense distress at the possibility of being left or rejected
- Impulsive behavior — actions taken in moments of strong emotion
BPD is often linked to early childhood trauma and to biological vulnerabilities in emotional regulation. It is important to note that people with BPD are not “manipulative” — they are experiencing real, intense distress and difficulty regulating it.
Narcissistic Personality Disorder (NPD)
Narcissistic Personality Disorder involves:
- A pattern of grandiosity — an exaggerated sense of self-importance
- A constant need for admiration
- Difficulty recognizing the needs and feelings of others
Importantly, these traits often mask deep-seated vulnerability and fragile self-esteem. Behind the outward confidence, a person with NPD may feel easily hurt or inadequate.
How do personality disorders affect daily life?
Because these patterns affect how a person relates to situations and people, they commonly affect relationships, work, and family life. There is often a cycle of conflict and distress — for the person, and for the people around them — that can feel exhausting and confusing for everyone involved.
When should someone seek professional help?
Seek help when patterns of emotion and behavior cause persistent distress, repeated difficulties in relationships, or problems with work or daily functioning — whether the concern is for yourself or for someone you care about. Because these patterns are long-standing, professional assessment helps bring clarity and a plan.
How are personality disorders diagnosed?
Diagnosis involves a careful, often repeated assessment of long-standing patterns of thinking, emotion, and behavior, and how they affect relationships and functioning. The psychiatrist will also look for other conditions, since anxiety, depression, and substance use commonly occur alongside personality difficulties. An honest, non-judgemental conversation is essential.
Treatment and management
These conditions require patience and enduring therapeutic relationships. Treatment focuses on:
- Specialized psychotherapies — such as Dialectical Behavior Therapy (DBT) for BPD — which are highly effective in teaching emotional regulation, distress tolerance, and healthy relationship skills
- Medications, where appropriate, to manage associated symptoms such as depression or impulsivity — always prescribed and monitored by a qualified psychiatrist
- Counseling and psychoeducation for the person and their family
The full range of care is described on the psychiatric services page.
Role of family and support
Families and partners often feel the strain of these conditions most directly. Support and psychoeducation help families understand the patterns as symptoms rather than personal attacks, set healthy boundaries, and encourage consistent treatment. This makes a meaningful difference over time.
Recovery and long-term management
Change is possible, but it is usually gradual. Building emotional regulation and relationship skills through consistent therapy, keeping follow-up appointments, and having supportive people who understand the condition all contribute to lasting improvement. With patience and the right support, people can develop healthier ways of relating to themselves and others.
If you are concerned about long-standing emotional or relationship patterns, an initial consultation is a confidential first step. See the contact page for how to reach the clinic.
