Solved Solutions.
Introduction to Mood Disorders - Answer Mood disorders are abnormalities in mood
occurring across a spectrum from depression to mania, affecting between 10-20% of the
population (Coleman et al., 2020). Mood disorders include depressive disorders and bipolar
disorders and may be comorbid with other physical and psychological conditions. Without
effective treatment, mood disorders may impact day-to-day living and the ability to relate to
others
Pathophysiology of Mood Disorders - Answer Mood disorders involve disturbances in mood
that occur across a spectrum from depression to mania. Mood disorders cause distressing
symptoms for clients, often impacting daily functioning and disrupting social relationships.
The exact pathophysiology of these disorders remains unclear but likely involves a combination
of genetic, chemical, and environmental factors. Neurotransmitters modulate communication
between neurons in the brain and influence various aspects of mood regulation. Imbalances or
dysregulation in neurotransmitter levels, such as serotonin, dopamine, and norepinephrine, are
commonly implicated in the development and manifestation of mood disorders. Decreased
levels of serotonin have been associated with symptoms of depression, while abnormalities in
dopamine and norepinephrine transmission are linked to mood disturbances characteristic of
conditions like bipolar disorder. Individuals with family members who have bipolar disorder are
also more likely to develop the condition. The interaction between genetic factors, chemicals,
and the environment may be contributory.
Pathophysiology of Bipolar Disorders - Answer Bipolar disorder is a mental illness that causes
extreme shifts in emotions, mood, and energy levels. Shifts in mood usually occur over several
days to weeks. Although bipolar disorder can be diagnosed at any age, it is most frequently
diagnosed in late adolescence or early 20s and is considered a lifelong condition.
The exact cause of bipolar disorder is unknown. Individuals with family members who have
bipolar disorder are more likely to develop the condition. The interaction between genetic
factors and the environment may be contributory. Brain imaging reveals white matter
hyperintensities, reduction in gray matter volume, increased ventricular size, and decreased
frontal cortical area volumes in some clients diagnosed with the disorder.
Bipolar I - Answer The diagnosis of bipolar I disorder requires at least one episode of mania
for at least one week (or any duration if hospitalization is required for symptoms). Hypomanic
episodes may also occur with bipolar I. Major depressive disorder (MDD) episodes are common
in bipolar I; however, they are not required criteria for diagnosis
Bipolar II - Answer Bipolar II disorder involves at least one major depressive episode and at
least one current or past hypomanic episode but no full mixed or manic episode (APA, 2022).
The key to diagnosis involves the length of time the symptoms persist. With hypomania,
, symptoms last for at least four days but fewer than seven and include the same symptoms as
mania without causing severe impairment or requiring hospitalization. Psychotic features are
not present with bipolar II disorder, although irritability and anger are common.
Depression - Answer Clients often present in the depressive state of the illness. Depressive
symptoms in bipolar disorder have a similar presentation to major depressive disorder (MDD).
Depression in bipolar disorder is characterized by a major depressive episode resulting in a
depressed mood or loss of interest or pleasure in life.
Mania - Answer Mania is characterized by an elevated, expansive, or irritable mood and may
be severe enough to cause significant impairment in social or occupational functioning, require
hospitalization to prevent harm to the client or others, or have symptoms that include psychotic
features (APA, 2022).
Hypomania - Answer Hypomania is a milder form of mania. To be diagnosed with
hypomania, the client must experience symptoms for at least four consecutive days, with
symptoms present most of the day and nearly every day. The client's energy level is higher than
normal but not as high as with mania. Hypomanic episodes can lead to challenges but do not
tend to lead to major issues with daily functioning. Hypomanic episodes do not involve
psychotic symptoms and are less likely to lead to hospital visits.
Mixed Episodes - Answer Mixed episodes in bipolar disorder involve the presence of
symptoms of depression and mania simultaneously.
DIG FAST - Answer - Distractibility: poorly focused, multitasking
- Insomnia: decreased need for sleeo
- Grandiosity: inflated self-esteem
- Flight of ideas: complaints of racing thoughts
- Activities: increased goal-directed activities
- Speech: pressured or more talkative
- Thoughtlessness: "risk-taking" behaviors (sexual, financial, travel, driving)
Mixed Episodes and Rapid Cycling - Answer - During mixed episodes, a client experiences
symptoms of depression and mania simultaneously, as seen in the image below.
- Rapid cycling describes an individual who has four or more episodes of depression and mania
within one year. Medications, such as valproic acid and lamotrigine, have been effective in
preventing rapid cycling associated with bipolar disorder.
Classic Euphoric Mania - Answer - Circumscribed episodes
- Low level of comorbidities
