The diagnosis of narcissistic personality disorder can only be made by mental health professionals. However, before taking that step, it is possible to recognize some warning signs that, as a guide, help to know if there is a probability that a person has developed this psychopathology.

Feelings Of Grandiosity
People with pathological narcissism have a tendency to greatly overestimate their objective abilities (for example, artistic abilities, mental agility, athletic abilities, etc.) and also believe that they deserve privileged treatment from others. It is as if they had inflated self-esteem, although, as we will see.

Self-Esteem Issues
Despite the grandiose characteristics typical of this personality disorder, very vulnerable self-esteem and high sensitivity to criticism are often hidden behind this façade of superiority, thus generating a dissonance that produces feelings of humiliation and can provoke angry or angry reactions.
Impulsivity
Individuals with narcissistic personality disorder expect everything to suit their immediate preferences and desires, and they feel great frustration if their environment does not provide them with what they think it should provide at all times. This dynamic based on self-centeredness makes it easier for them to get used to constantly giving in to their impulses, adopting a short-term view of their own well-being. Therefore, it is not surprising that among people with narcissistic personality disorder, there is a predisposition to drug use (which does not mean that all of them suffer from addictive disorders or take psychoactive substances regularly).
However, as we will see, the fact of developing this psychopathology does not imply that the ability to repress impulses is entirely annulled. In some cases, those who suffer from narcissistic personality disorder are capable of adopting an obsessive mentality with the avoidance of certain experiences if they perceive that they threaten their identity or desire “I”.
Tendency to take great care of the appearance
As narcissistic personality disorder has a lot to do with seeking admiration and approval from others, it is very common for these people to take extreme care of their image. In some cases, this makes them vulnerable to developing very serious illnesses; thus, it has been seen that among them, there is a higher percentage of individuals with anorexia nervosa.
Treatment for narcissistic personality disorder
Currently, there is no psychological treatment that can completely reverse any personality disorder, so psychotherapeutic support is applied with the aim of mitigating symptoms and offering the person and their environment the necessary tools to lead a life as comfortable as possible autonomous and happy as possible.
Yes, there are some management strategies and recommendations to treat each personality disorder in the clinical setting. Regarding narcissistic personality disorder, measures are taken such as not entering into a power struggle with the patient; Given the tendency to show fanciful thoughts, we will help them focus on more concrete and real issues, set realistic goals and work on possible cognitive distortions that may be present.
