So if these illnesses are so much alike and DBT has been researched extensively and found to be helpful for the treatment of borderline personality disorder, it only makes sense that DBT will also be helpful in treating bipolar disorder. Even if the two illnesses are not one and the same, the many shared symptoms and the fact that there is a high rate of co-occurrence of the two disorders (meaning people diagnosed with one often also have the other) suggests that DBT is an effective treatment for bipolar.
Since its beginnings, DBT has also been successfully used to treat many other illnesses, such as other personality disorders, depression, substance abuse and dependence, eating disorders, and self-harming and suicidal behaviors. People with bipolar disorder can also face these problems, and DBT can help.
There has been only one published study on the use of DBT for bipolar disorder. The authors of the study reported that the results were positive, with the participants exhibiting significant improvement in suicidality, self-harming behavior, regulation of emotions, and symptoms of depression.
