“Narcissist” has become the word for every selfish ex, controlling boss and difficult parent. Sometimes it fits the behaviour. It rarely means a diagnosis. Here’s the difference, and why the behaviour matters more than the label.
“Narcissist” is everyday slang for someone self-centred. Narcissistic personality disorder (NPD) is a diagnosis: a long-standing pattern of grandiosity, need for admiration and lack of empathy across someone’s whole life. Careful estimates put it at 1 to 2 in 100 adults. Harmful behaviour counts either way.
What NPD actually is
NPD is a diagnosis in the American Psychiatric Association’s manual, DSM-5-TR. It describes a lasting pattern that starts by early adulthood, shows up across work, family and relationships, and includes at least five of these nine features:
- An inflated sense of their own importance and talents
- Fantasies of unlimited success, power, brilliance, beauty or ideal love
- Believing they’re special and should only mix with high-status people
- Needing excessive admiration
- A sense of entitlement
- Exploiting others to get what they want
- Lack of empathy
- Envy of others, or believing others envy them
- Arrogant, haughty behaviour
The pattern also has to cause real problems, and a qualified clinician has to rule out look-alikes, such as the grandiosity of a manic episode or the effects of drugs.
The World Health Organization’s classification, ICD-11, doesn’t have NPD at all. It has one diagnosis, personality disorder, rated mild, moderate or severe, with trait labels. Narcissistic features mostly fall under “dissociality”: self-centredness and lack of empathy.
Narcissism is a scale, not a type
Everyone sits somewhere on a scale of narcissism. When researchers tested NPD traits across five groups of people, the traits fitted a single scale better than a separate “narcissist” category.
Narcissism also has two faces:
- Grandiose: bold, charming, entitled, domineering.
- Vulnerable: just as self-centred, but anxious, touchy, easily shamed and withdrawn.
Many people show both. “Covert narcissist” is a popular name for the vulnerable side, but it isn’t a separate diagnosis, and experts advise against treating overt and covert as two types of person.
Narcissistic traits become a disorder when they’re rigid, show up everywhere and cause serious harm. In one study, NPD was linked more strongly with causing others pain than with the person’s own distress. On average, narcissism also softens with age.
How common NPD is
Careful estimates put NPD at about 1 to 2% of adults. You may see 6.2% quoted. That came from a US survey with loose scoring, and when researchers rescored the same data, counting only traits that caused distress or problems, it fell to about 1%.

More men are diagnosed, but the gap in everyday narcissism between men and women is small, and there’s no gap in the vulnerable kind.
So most people called narcissists online wouldn’t meet the criteria. In a 2026 study, about a quarter of participants held ideas of NPD so broad that they took in ordinary behaviour.
Why you can’t diagnose your ex, and don’t need to
A diagnosis needs an assessment of someone’s whole life. ICD-11 says behaviour seen only in particular relationships or situations isn’t enough to diagnose a personality disorder. Your partner, boss or parent may behave very differently elsewhere. The American Psychiatric Association tells its members not to diagnose public figures they haven’t examined, so an Instagram diagnosis deserves even more caution.
Labels can also backfire. Calling someone a narcissist can end a conversation about what actually happened, and clinical words used loosely can be used to dismiss or discredit people.
You don’t need the label. “He puts me down in front of people” or “She controls all the money” is clearer, and it’s what matters for your safety and your choices.
“Narcissistic abuse”: the label isn’t a diagnosis, the harm is real
“Narcissistic abuse” isn’t a diagnosis or a legal term. But the behaviours people mean by it are recognised forms of abuse:
- belittling you, or blaming you for the abuse
- isolating you from family and friends
- controlling money, or stopping you from working
- checking your phone, or telling you what to wear and who to see
- threats, and gaslighting: making you doubt your own memory or sanity
Psychological abuse by a partner is strongly linked with depression, anxiety and PTSD, whatever the abuser’s diagnosis. In Nigeria’s 2023–24 Demographic and Health Survey, about 1 in 5 women aged 15 to 49 who’d had a partner reported emotional violence from a husband or partner.
The law looks at behaviour, not diagnoses. The Violence Against Persons (Prohibition) Act 2015 makes emotional, verbal and psychological abuse an offence: a pattern of degrading or humiliating conduct, such as repeated insults, ridicule, repeated threats or obsessive possessiveness. The penalty is up to a year in prison, a fine of up to ₦200,000, or both. The federal Act applies only in the FCT, but almost every state has passed its own version; in May 2026, FIDA said Kano was the only state that hadn’t. Courts can also grant protection orders, and a counsellor or health worker can apply for one on your behalf with your written consent.
What to do about the behaviour
- Notice fear. If you’re afraid of someone, or changing what you do to avoid their reaction, take that seriously.
- Set clear limits and keep them.
- Keep records: dates, messages, photos, witnesses and any medical visits. They can support an application for a protection order.
- Get support. Talk to people you trust. For women experiencing partner violence, therapy probably reduces depression.
- Plan any exit with help. Leaving is often the right choice, but separating from a controlling partner is a known high-risk time, so make a plan with support first.
- Be wary of trendy tactics. “Grey rock” (becoming dull and unresponsive) has no research behind it. Cutting contact after a breakup may help some people recover, but it may be impossible with shared children, and with a controlling ex it needs a safety plan.
- With a boss, keep dated records, use HR or grievance channels, and get support outside work.

Can someone with NPD change?
Change is possible, usually slowly over years, and narcissism tends to soften with age. But no therapy is proven for NPD yet. The first randomised trial was published in 2026, and a group of international experts has questioned its methods.
People with narcissistic traits often come to therapy for depression, a crisis, or a partner’s ultimatum rather than for their personality. Empathy isn’t always missing: in experiments, people high in narcissism felt more empathy when asked to imagine another person’s view.
You can’t make someone change. You can decide what you’ll accept. And if you recognise yourself in this article, that’s worth taking to a therapist.
Getting help
You can find a therapist who works with personality disorders, or a relationship counsellor, by video, voice or chat. Read more about personality disorders, see our personality disorders page, or look up NPD in our glossary.
Frequently asked questions
What does NPD mean?
NPD stands for narcissistic personality disorder: a long-standing pattern of grandiosity, need for admiration and lack of empathy that causes real problems. Only a qualified clinician can diagnose it.
Is every selfish person a narcissist?
No. Everyone has some narcissistic traits. NPD is uncommon, about 1 to 2% of adults, and needs a pattern across the person’s whole life, not just one relationship.
What is a covert narcissist?
It’s a popular name for the vulnerable side of narcissism: self-centred, but anxious, touchy and easily shamed. It isn’t a separate diagnosis.
Can a bad relationship turn you into a narcissist?
No evidence says so. Personality disorders start by early adulthood. Abuse is more often linked with trauma, depression and anxiety, and a survivor’s anger or guardedness can be mistaken for narcissism.
Can a narcissist change?
Some people do, slowly, and narcissism tends to soften with age. No therapy is proven for NPD yet, and change depends on the person wanting it. You can still decide what behaviour you’ll accept.
