Narcissism is a disorder characterized by a lack of empathy for others, a lack or inability to relate to others, and a belief that others have a right to judge you, according to the Diagnostic and Statistical Manual of Mental Disorders, or DSM.
But there are also many who suffer from narcissistic personality disorder (NPD) or borderline personality disorder, which can result in severe and pervasive anger and antisocial behavior, according the National Institute of Mental Health.
A study published last year by the University of Texas found that of the more than 4,000 people surveyed, more than a third were suffering from narcissistic symptoms and two-thirds were severely or permanently affected by NPD.
“There are many ways to diagnose NPD,” said Dr. Matthew M. Cogan, the director of the Institute for the Study of Personality and Social Psychology.
“If someone’s in the hospital and they have the signs and symptoms of narcissistic personality, they can be diagnosed and treated.”
Cogan said he has treated more than 30 people in his clinical practice with NPD and that he believes the symptoms can be treated with a combination of medication and psychotherapy.
NPD can also be caused by certain genetic factors, he said.
If your doctor has been treating someone with narcissistic symptoms for years, there’s a good chance you will have some of the symptoms themselves.
And even if your symptoms are mild, you can still develop other signs of NPD, he added.
In the study, researchers looked at data from over 3,400 people who participated in the Diagnosis and Treatment of Narcissistic Personality Disorder (DTP) trial, which included an array of behavioral tests, including the BDI, the NEO Personality Inventory, the Structured Clinical Interview for DSM-IV-TR and the Short Form-36.
Of those people, more a quarter were diagnosed with narcissistic personality disorders and 19 percent had borderline personality disorders, according a press release from the university.
Among those who were diagnosed, about a third had severe and persistent NPD symptoms.
The study found that people with NPHD were more likely to have a history of violence, have narcissistic personality traits and have a high rate of substance abuse.
“These people were significantly more likely than the general population to have NPHDs and borderline personality traits,” Dr. Cechan said.
“But we did not find any evidence of a link between narcissistic personality and violent behavior.”
Researchers found that about one in three people with narcissistic traits, NPHDS and borderline personalities have a diagnosable psychiatric disorder, such as borderline personality and psychotic disorder, according Cogan.
But when researchers looked for other risk factors that may cause narcissistic personality to develop, they found that some of these were common among the population at large.
“We found a very strong association with having a family history of narcissistic abuse,” Cechin said.
For instance, the researchers found that a person who had a family member who was narcissistic was more likely or more likely of having an NPH-type disorder than those who did not have such a history.
Cochin said it’s possible that these common risk factors were related to the way in which narcissistic personality develops in children.
But Dr. Thomas M. Reis, the lead author of the study and an associate professor at the University at Buffalo School of Medicine, said the findings show that narcissistic personality is not just something that develops in a child.
“Narcissism develops in adults,” he said in a statement.
“In fact, it can even lead to serious consequences in later life.”
Ceching’s work, and his work with other experts, suggests that the symptoms of narcissism may be a symptom of some underlying health issue, he noted.
CECHING: A narcissist is like a ticking time bomb, but we don’t know if the ticking is ticking too fast, or not.
It could be that the narcissist has narcissistic symptoms that could be triggered by stress or some other event, like a family situation, Cechi said.
However, it’s important to understand that these symptoms do not mean that the person is psychotic, Reis said.
NPH, BPD, and borderline traits are the same disorder, Reisen said.
The symptoms can also change depending on the severity of the illness.
“You can have a narcissistic personality without a BPD or NPH disorder,” he added, but the narcissism can also affect people with other disorders, like alcohol abuse, depression and anxiety.
“When you have severe narcissistic symptoms, you will develop a range of other disorders that include anxiety, anxiety disorders, mood disorders, substance abuse, eating disorders, eating pathology,” Reis explained.
“What I do find is that people who have narcissistic symptoms are at higher risk for having other disorders.”
He added that the number of people who report NPH symptoms is growing, and more and more people are starting to report the condition in their own lives
