- Bipolar disorder: a highly recurrent psychiatric illness characterized by fluctuating periods of manic/hypomanic features (distractibility, impulsivity, increased activity, decreased sleep, talkativeness, grandiosity, flight of ideas) and depressive symptoms. Management includes mood stabilizers such as lithium, anticonvulsants, and antipsychotics. Loss of judgement and gambling are common features of a manic episode. Careful history taking must rule out bipolar disorder as underlying the gambling behavior.
- Nonpathologic gambling: when a patient does not meet the criteria for diagnosis or participates in professional or social gambling. This type of gambling typically has a reduced or acceptable amount of risk compared with that found in gambling disorder.
