The modern concept of the diagnostic entity has emerged from influences starting from the late 19th century. The diagnostic term "borderline" came from English psychiatrist C.H Hughes in 1884, which wrote an article called "Borderland Psychiatrist Records" where he mentioned borderline for the very first time. Symptoms of BPD were not clustered by either neurosis or psychosis. Borderline Personality disorder is a psychological condition characterized by interpersonal dysfunctions, unstable relationships, emotional dysregulation, suicidal behavior, impulsive aggression, and rapid switched between idealizing and devaluing relationships. Severe psychiatric conditions are characterized by a pervasive pattern of marked impulsivity and instability in affects of oneself image and interpersonal relationships. .
Borderline Personality Disorder is formed from impoverished self-image, internal emptiness, stress related to dissociation, instability of goals and plans, hypersensitivity, negatively skewed perceptions, unstable or conflicting relationships. Sigmund Freud provided a description of symptoms for diagnosing BPD, which was referred to as a subgroup in hysteria. In 1938, American psychoanalyst Adolf Stren described most symptoms that lead to the modern diagnosis of BPD by using the expression "borderline group of neuroses". This term is important due to the tendency patients having shown "borderline" mental states of schizophrenia. Borderline was inconsistent colloquialism until 1967 when O.F Kernberg described Borderline Personality Organization as a level of psychological functioning. The organization featured primitive defenses, projective identification diffusion and difficultly in reality testing.
