Bipolar Vs. Borderline Personality Disorder (BPD)


Often, people confuse between the two because of the similarities, but to differentiate, know that BPD is a personality disorder, while bipolar is a mood disorder. Previously, bipolar disorder was known as a manic-depressive disorder because of the extreme highs and lows of episodes of mania and depression, respectively. These episodes last for weeks and months at a stretch. Remember, getting an accurate diagnosis is important to finding the right treatment plan, as both have different treatment methods.


Classifying the mental health disorder correctly is essential for the proper treatment. There are different personality disorders, such as;

  1. Borderline personality disorder
  2. Antisocial personality disorder
  3. Histrionic personality disorder

People often think bipolar is a personality disorder when it is not. Bipolar is a mood disorder; let’s look into further details of bipolar disorder.

Is Bipolar a Personality Disorder?


No, bipolar condition affects the mood, energy levels, and ability to function of an individual. People with bipolar usually have sudden mood changes, which only a healthcare provider can diagnose. It is not classified as a personality disorder. It is an intense emotional phase that lasts a few days or weeks. In short, mood disorders can be further classified as;

1. Maniac disorder includes hypomanic episodes where an individual shows high energy levels and unpredictable behavior.

2. Depressive episodes/manic depression During this phase, the individual has low levels of energy and feels hopeless and down.

Seek immediate help or visit a healthcare professional if the mood disorder lasts a long time. Constant mood shifts or fluctuations hinder the ability of an individual to function correctly. People with bipolar disorder have difficulty in holding a job, remaining in school, and building relationships. However, help is available, and individuals with bipolar disorder can now lead an everyday fulfilling life.

Personality vs. Mood Disorders- Key Differences


As mentioned earlier. Bipolar disorder and borderline personality disorder are completely different. Let’s look at the key differences between the two.

1. Mood Disorders


Both personality and mood disorders are mental health conditions. Mood disorders are further divided into bipolar disorders and depressive disorders. Mood disorders are commonly known as affective disorders, as these health conditions seriously affect the emotional state of a person. An individual suffering from mood disorder has extreme highs and extreme lows. Bipolar affects the mood, ability to function, and overall energy levels.


Mood disorders are further classified into;

  • Bipolar I and II disorder
  • Cyclothymic disorder

The first two are types of bipolar disorder

  • Disruptive mood dysregulation disorder- DMDD
  • Major depressive disorder MDD
  • Premenstrual dysphoric disorder and
  • Persistent depressive disorder PDD

Mood disorders can be managed with medications along with online bipolar therapy. Usually, mood disorders are short-term. Rarely do they last for a long time.


Symptoms of Bipolar Disorder

  • Mood episodes that last a week or so
  • Mood swings
  • Restlessness
  • Racing mind
  • Impulsive behavior
  • Increase in activity and energy
  • Risky behavior 
  • And psychosis (during manic episodes)

Causes of Bipolar Disorder


1. Stress & Trauma- both are interconnected. Stress plays a massive role in developing bipolar disorder. 

2. Genetics- bipolar is genetically inherited and runs in the family. 

3. Brain Differences- Some studies show that an individual with bipolar disorder has a different structure of the brain. 

2. Personality Disorders


In contrast to mood disorders, personality disorders are longer lasting. People who have borderline personality disorder find it challenging to regulate their emotions, affecting their lives overall.


Personality disorder also affects the emotional state of our minds. It involves feelings, behaviors, and thoughts. These actions affect how the individual;

  • Think about themselves
  • Respond to situations
  • Control their behaviors and 
  • Relate to others.

An individual with BPD has the following patterns;

  • To begin with, a mental health care provider will ask a series of questions, including symptoms, duration, and seriousness of the episode.
  • Next, they will take the medical history of the family and check whether anyone has any other mental health issues.

1. Bipolar I diagnosis- the individual had one full-fledged episode of mania for almost a week and was hospitalized as a result
