There is a fair amount of confusion among lay people about the difference between these two particular disorders in teenagers. In addition to having names that sound similar, they both involve a fair amount of emotional disregulation. However, they are quite different. Bipolar Disorder is a biological disorder comprised of periods of depression, mania, and normalcy. It requires medication to manage it over the course of one’s lifetime. Borderline Personality Disorder is a complex of traits or tendencies that are dysfunctional and problematic, creating difficulty in many areas life. While it may be helped by medication, medication is not required. Talk therapy, particularly DBT (Dialectical Behavioral Therapy) that focuses on learning a set of coping skills to assist with regulating mood and behavior, is the treatment of choice. In addition, teenagers with Borderline Personality traits or tendencies, tend to get somewhat better just with age and maturity, even without treatment. However with treatment, they can overcome the disorder. With both Bipolar Disorder and Borderline Personality Disorder, education about the disorder as well as how to manage it is extremely helpful.

One of the diagnostic criteria for Borderline Personality Disorder, and all of the personality disorders in fact, is that it cannot be diagnosed until it has exhibited itself for a number of years. For that reason, most clinicians wait until an adolescent is eighteen or older to make this diagnosis. However, if someone under eighteen has clearly exhibited the symptoms for a number of years prior to the age of eighteen, the diagnosis can be given.

Diagnosis for Bipolar Disorder is often difficult, because no one ever sees the entire disorder at any given time. Since it involves longer episodes of depression or mania and often periods of normalcy in between, a person with Bipolar Disorder is sometimes misdiagnosed with having a Major Depression instead. For that reason, it is important to get a thorough history of the teenager’s symptomology including any earlier periods of depression or mania. It is also important to look at family history since Bipolar Disorder has a genetic component to it. One reason it is important to have a more accurate understanding of whether a person is experiencing a Major Depressive Disorder or a Depressive Episode within a Bipolar Disorder, is the fact that an anti-depressant medication alone can trigger a manic episode in someone that has Bipolar Disorder. If someone has a history of Bipolar Disorder in their family and are experiencing a Major Depression, it would be important for them to have a mood stabilizer in addition to an anti-depressant medication to avoid the possibility of triggering a manic episode.

According to the DSM-IV TR (Diagnostic and Statistical Manual for Mental Disorders) the criteria for the depressive and manic episodes of Bipolar Disorder are:

Major Depressive Episode:

1) Depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad or empty) or observation made by others (e.g., appears tearful). Note: In child and adolescents, can be irritable mood.
2) Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated by either subjective account or observation made by others).
3) Significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day. Note: In children, consider failure to make expected weight gains.
4) Insomnia or hypersomnia nearly every day.
5) Psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down).
6) Fatigue or loss of energy nearly every day.
7) Feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick).
8) Diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others).
9) Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide.

Manic Episode:

A. A distinct period of abnormally and persistently elevated, expansive, or irritable
mood, lasting at least one week (or any duration if hospitalization is necessary).

B. During the period of mood disturbance, three (or more) of the following
symptoms have persisted (four if the mood is only irritable) and have been present
to a significant degree:

1) Inflated self-esteem or grandiosity
2) Decreased need for sleep (e.g., feels rested after only three hours of sleep).
3) More talkative than usual or pressure to keep talking.
4) Flight of ideas or subjective experience that thoughts are racing.
5) Distractibility (i.e., attention too easily drawn to unimportant or irrelevant external stimuli)
6) Increase in goal-directed activity (either socially, at work or school, or sexually) or psychomotor agitation.
7) Excessive involvement in pleasurable activities that have a high potential for painful consequences (e.g., engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments).

C. The symptoms do not meet criteria for a Mixed Episode.

D. The mood disturbance is sufficiently severe to cause marked impairment in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.

E. The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication or other treatment) or a general medical condition (e.g., hyperthyroidism).

Note: Manic-like episodes that are clearly caused by somatic antidepressant treatment(e.g., medication, electroconvulsive therapy, light therapy) should not count toward a diagnosis of Bipolar I Disorder.

According to the DSM-IV the criteria for Borderline Personality Traits are:
1) Frantic efforts to avoid real or imagined abandonment. Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5.
2) A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation.
3) Identity disturbance: markedly and persistently unstable self-image or sense of self.
4) Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating).
Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5.
5) Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.
6) Affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability or anxiety usually lasting a few hours and only rarely more than a few days).
7) Chronic feelings of emptiness.
8) Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights).
9) Transient, stress-related paranoid ideation or severe dissociative symptoms.
