Patients with NPD may also meet criteria for separate axis I diagnoses (eg, major depressive disorder, bipolar disorder, or a substance-related disorder). Alternatively, patients with only NPD may at times have symptoms that mimic those of axis I disorders, such as grandiosity that is mistaken for the mania or hypomania of bipolar disorder. [19]

It is therefore important to ascertain the exact nature and duration of the symptoms, keeping in mind that personality disorders are associated with long-standing, chronic patterns of behavior rather than isolated episodes of transient pathology.
