Introduction to Mood Disorders
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 dayto-day living and the
ability to relate to others.
Depressive symptoms in mood disorders may include persistent feelings of
hopelessness and sadness or expressing self-negativity. Individuals with mood
disorders often experience persistent and intense fluctuations in mood, ranging
from extreme sadness or despair alternating with periods of elevated mood or
irritability. In bipolar disorder, individuals who experience episodes of mania or
hypomania may be characterized by elevated mood, increased energy, racing
thoughts, impulsivity, inflated self- esteem or grandiosity, decreased need for
sleep, excessive involvement in activities, and risky behaviors such as reckless
spending or substance abuse.
An isolated breach in decision-making (e.g., cooking supper) is not related to a mood
disorder.

Clients with unipolar disorder will likely experience high self-esteem during a
manic episode. The same symptoms characterize unipolar depression as major
depressive disorder (MDD).
Bipolar, not unipolar, depression is characterized by extreme agitation and
hallucinations.
Dopamine is synthesized from the amino acid tyrosine, and its synthesis plays a
role in neurotransmission. Alterations of dopamine on receptors can affect
mood, pleasure, and motivation.
Glutamate, not dopamine, affects sleep cycles.
Pathophysiology of Mood Disorders
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
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.
Types of Bipolar Disorders
Bipolar disorder encompasses a wide range of symptoms and is classified
according to the types of mood episodes exhibited.
Bipolar I and II are the most frequently diagnosed types of bipolar disorder:
• Bipolar I: 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 (American Psychiatric Association [APA], 2022).
