Diagnosing Borderline Personality Disorder: Signs, Symptoms, and Tests


The study of various complicated aspects of human behavior dates back to ancient times while the discovery of personality disorders is a very new phenomenon. The disorders characterized by persistent and dysfunctional behaviors that are disruptive throughout a person’s life usually go unnoticed. These are as defined by the DSM-5 where they refer to departures from social norms that deeply affect people’s inner experiences and behavioral tendencies.

It is important to note that among some of the prevalent personality disorders borderline personality disorder and antisocial personality disorders are highly prevalent making it difficult for one to acquire employment, maintain significant relationships, and enjoy normalcy in their lives. The NCS-R (National Comorbidity Study Replication) indicates that 9.1% of Americans of adult age suffer from at least one of these disorders.

Recent self-assessment tests have revealed the presence of such different levels of symptoms, as for example the relatively benign manifestations of narcissism, or severe and worrisome impairment in the capacity to empathize. BPD is one of the main reasons that patients are admitted in psychiatric hospitals and it often takes a significant part in a patient’s mental illness-related hospitalization yearly basis, usually accounting for about 15-25%.

Diagnosing Borderline Personality & Testing for Multiple Personalities:

BPD is considered to be a complicated condition with misconceptions in regard to its origin causing the way one thinks, feels, and acts. Marked impulsivity, as well as a pervasive disturbance in attachment, self-image, and mood manifesting as instability. People struggling with borderline personality disorder often suffer very serious psychological crises characterized by switches in moods of emptiness, rage, or fear. The emotional instability in women can cause a lot of problems with stable relations and self-sense. It is estimated that two-thirds of the patients diagnosed with BPD are women.

Now moving away from the complexity of BPD, let us focus on the different characteristics of an individual with borderline personality disorder. These are hallmark of this complex condition which must be understood for proper diagnosis and management. We shall examine the common signs and symptoms of this illness.

Signs and Symptoms of Borderline Personality Disorder:

If one is aware of the symptoms of BPD, early diagnosis is possible. Most times these signs and symptoms are ignored which brings greater trouble for the patient. Here are some common symptoms of BPD:

Mood Swings: People suffering from BPD usually have significant mood changes that can transition quickly to severe rage through deep depression into ecstasy. These mood changes are quite demanding and often distressing.

Risky Behaviors: People with BPD may undertake dangerous practices such as high-speed driving, alcoholism, or other drug use. This usually happens as a result of trying to relieve the emotional pain.

Unstable Self-Image: It is common for people suffering from BPD to experience problems concerning their ever-changing self-images, thus making it difficult to maintain a stable sense of self. These problems in turn manifest as identity crises and problems with relationships.

Self-Harm: BPD patients try to harm themselves generally by cutting or burning themselves as they utilize escape mechanisms. As coping mechanisms, they try to alleviate the suffering and also feel empowered.

Suicidal Thoughts: BPD patients frequently witness unsupportable studies of death, commit self-murder, and attempt to do so. It is worth noting that almost two-thirds of people with BPD have engaged in self-harming behavior (70% – 75%).

Diagnosing Borderline Personality Disorder:

If you think you or a loved one may have BPD, it can be very helpful to educate yourself about borderline personality disorder diagnosis. Being armed with this information can help you take the next step.

Diagnostic and Statistical Manual of Mental Disorders (DSM-5): Diagnostic criteria for BPD are available in the DSM-5. These criteria are what mental health professionals depend on for an examination of a patient’s symptoms, behavior, and history.

Clinical Interviews: During the diagnostic process, mental health professionals subject the person to a thorough interview. Through these interviews, extensive history is obtained while symptom screening for BPD is done.

Observations: Time of observation is a necessary step in diagnosis. Professionals are expected to watch out for their clients to ensure that they maintain the same symptoms throughout the period.

Questionnaires: Other mental health professionals might be using standard scales or questionnaires that evaluate particular signs of having a borderline personality disorder, like the Borderline Personality Questionnaire.

Tests for Multiple Personality Disorder:

Introduction: Multiple Personality Disorder and Dissociative Identity Disorder are among complex psychological conditions that involve the development and existence of multiple personalities in an individual. Each identity has its distinct set of traits (i.e., behavioral, memory, mannerism) that take over the person and cause significant disturbances in their everyday life and daily function. Hence, understanding the nuances involved in this case is crucial when it comes to making accurate diagnoses as well as incorporating appropriate treatments.

It is important to distinguish BPD from other disorders such as Dissociative Identity Disorder (DID) when making a diagnosis. A desirable testing tool for detecting DID is the Descriptive Event Schedule (DES). The administered test could enable people to get an understanding of the experience in order to direct the required care.

Dissociative Identity Disorder (DID):

Dissociative identity disorder refers to multiple personality disorder in which one suffers from split personalities or multiple states of mind at times. These separate individualities can possess their names, and mannerisms and could store some memories. They may arise out of nowhere and drive one’s behavior, causing amnesias & blackouts.

Dissociative Experiences Scale (DES):

The dissociative Experiences Scale is a popular self-report scale for the measurement of the occurrence and intensity of dissociative experiences in persons. It helps to assess the degree of depersonalization manifested as a disconnection to one’s thought processes, emotions, memory, and self-identity. Many times this scale has been used when evaluating different types of dissociative disorders, such as DID and others.

Understanding Borderline Personality Disorder in the Context of Mental Health:

Complex mental health problems include Borderline personality disorder (BPD).

According to research, this is a complex issue involving biological development along the genetic aspects and the environment at large. In addition, individuals with a background including traumas, neglect, or abuse in their pasts are prone to BPD.

The problem with diagnosing BPD is that it has a lot in common with other mental disorders thus making the diagnosis difficult. For example, some signs and symptoms of BPD may mirror those of bipolar disorder or major depression thus resulting in misdiagnosis or delayed diagnosis. This emphasizes the need for detailed assessment by mental health experts to correctly diagnose BPD and instigate treatment accordingly.

The Role of Psychotherapy and Medication in BPD Treatment:

DBT helps people with their emotions, ways of relating to others, and ability to deal with stress. Specific symptoms are likewise handled using cognitive behavior therapy in addition to promoting healthy behavior change.

Although medications are not a first-line intervention in BPD, they can be used to treat some symptoms like depression, anxiety, etc. Some of the medical options that could form part of a wide scheme of treatments include antidepressants, mood stabilizers, and antipsychotic drugs. Despite this, drugs should also be combined with psychotherapy and taken while under competent medical attention.
