Differences between Bipolar II Disorder and Bipolar I Disorder per DSM 5-TR

Bipolar disorders are closely related in terms of symptom presentation and diagnostic criteria. However, there are notable symptomatic differences and specific diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5 TR) for bipolar I disorder and bipolar II disorder. For instance, the diagnostic criteria for bipolar II disorder as per the DSM-5 TR, an individual must have experienced at least one major depressive episode and one hypomanic episode in which the major depressive episode lasts at least two weeks while the hypomanic episodes are experienced for at least four consecutive days (American Psychiatric Association, 2021). On the other hand, bipolar I disorder is diagnosed based on the presence of at least one single manic episode without any symptoms of a major depressive episode. Regardless, major depressive disorder symptoms may be present in a patient with bipolar I disorder, but the episodes are not necessary for the diagnosis of the condition as it is with bipolar II disorder (American Psychiatric Association, 2021).

Besides the differences noted in the diagnostic criteria for bipolar I disorder and bipolar II disorder, there are some clearly outlined differences in both bipolar disorders as per the DSM-5 TR. Bipolar I disorder and bipolar II disorder differ majorly in the severity of the symptoms presented by a patient and how long the symptoms last. According to the DSM-5 TR, bipolar I disorder is characterized by severe symptoms such as full manic episodes lasting for over a week resulting in functional impairments and the need for hospitalization. On the other hand, bipolar II disorder is characterized by mild and shorter episodes and symptoms such as hypomanic episodes that may last up to four days (American Psychiatric Association, 2021).

Special Populations and Considerations for Bipolar II Disorder

The impact of bipolar II disorder as well as the severity of the symptoms varies across the population. This means that the strategies applied towards the management of bipolar II disorder will differ in children, adolescents, pregnancy/post-partum, older adults, and emergency care. This requires special considerations across these population groups. For children and adolescents, considerations need to focus on the diagnosis of the disorders as the symptoms tend to overlap with other related mental health issues in this population group. Children and adolescents have rapid mood changes and experience episodes of mixed feelings, majorly characterized by maniac and depressive symptoms (Abrams, 2020). The impact of bipolar II disorder in children and adolescents differs from other population groups as they are in their major developmental stages. The disorder can impact the physical and cognitive development of children and adolescents. Additionally, due to the lack of clinical trials on children, there is a need to consider the legality and ethics of available treatments as well as their effects on this population.

Pregnant and post-partum patients are considered special populations requiring special considerations for the management of bipolar II disorder. The condition in pregnant and postpartum patients is a challenge as the medications and psychotherapeutic approaches applied in managing the condition can significantly impact pregnancy and milk production. Considerations need to be made when dealing with pregnant and post-partum patients; the care approaches employed for bipolar II disorder need first to determine the potential risks associated with pharmacological and nonpharmacological approaches to care. There is also a need to consider the cultural views of mental illnesses during pregnancy and postpartum period.

Elderly patients are more affected by bipolar II disorder than other populations. Although the condition can develop during the early days, it becomes prominent later, especially during the patient’s 50s. Managing bipolar II disorder in older adults can be challenging due to the presence of other conflicting illnesses related to old age. Considerations when treating bipolar disorders in older patients need to consider the manifested symptoms in relation to age-related cognitive changes as well as the age-related changes in pharmacokinetics and pharmacodynamics of available modalities (Ljubic et al., 2021). Considerations also need to be made on the ability of elderly patients to access available care options as well as the ability of the patient to make sound care decisions.

Regardless of the population group, managing bipolar II disorder emergencies needs to consider several individual patient factors, such as the underlying factors of the condition, including age, health status, current medication regimen, and presenting symptoms. Despite the need for emergency care, the care providers need to consider the legality an
