Bipolar disorder is a mental health condition where a person experiences intense mood changes. These mood changes can vary from periods of high energy and excitement (mania) to episodes of deep sadness and hopelessness (depression).
Bipolar disorder can result in mood changes due to brain changes that affect how you regulate emotion. External stressors and life events can also trigger symptoms for some people.
Is there a connection between bipolar disorder and mood changes?
Mood changes and bipolar disorder are related to one another, as mood changes are a hallmark symptom of bipolar disorder. According to a 2022 study, changes in neurotransmitter levels and activity within the brain may be the reasons people with bipolar disorder experience mood changes. Neurotransmitters are chemical messengers that help brain cells communicate with each other.
The study suggested that people with bipolar disorder often have imbalances in neurotransmitters such as dopamine, serotonin, and norepinephrine, which help regulate mood, emotions, and thinking abilities.
During manic episodes, there is an excess of neurotransmitter activity, primarily involving dopamine. This increased dopamine can cause heightened energy, euphoria, and impulsivity. However, during depressive episodes, there may be reduced activity of these neurotransmitters, leading to feelings of sadness, hopelessness, and decreased motivation.
An older 2015 study also revealed structural and functional abnormalities in specific brain regions responsible for mood regulation in people with bipolar disorder. These abnormalities affect the circuits involved in emotional processing, leading to intense mood changes.
What do mood changes look like in bipolar disorder?
Mood changes refer to rapid and extreme shifts in emotional states. In bipolar disorder, mood changes can often be intense and involve distinct periods of mania and depressive episodes. They may last for days, weeks, or even months.
Manic episodes
During manic episodes, you may experience an extreme and persistent elevation in your mood. Although it may initially appear positive, mania can escalate rapidly and become harmful to your daily functioning.
Some common symptoms of manic episodes include:
- intense euphoria
- extreme irritability
- increased energy levels and decreased need for sleep
- impulsive behavior, such as excessive spending or engaging in harmful sexual behaviors
- racing thoughts and rapid speech
- having exaggerated beliefs about your abilities or feeling a sense of superiority (grandiose beliefs)
- difficulty concentrating and being easily distracted
However, mania can manifest differently in every person. Some people may show highly productive and goal-directed behavior, while others may experience extreme restlessness or agitation. In severe cases, mania can escalate to a state of psychosis, which involves hallucinations or delusions.
Depressive episodes
Depressive episodes in bipolar disorder involve profound sadness, hopelessness, and a loss of interest or pleasure in activities you previously enjoyed.
Depressive symptoms may include:
- persistent feelings of sadness, emptiness, or worthlessness
- fatigue or loss of energy, leading to decreased motivation
- increase or decrease in appetite or weight
- insomnia or excessive sleeping
- difficulty concentrating, making decisions, or having trouble with memory
- recurrent thoughts of death or suicide
Depressive episodes can be challenging and may significantly affect daily life, including work, relationships, and overall well-being.
However, not every person with bipolar disorder experiences the same symptoms, and the severity can also vary. Additionally, periods of stability can occur between episodes.

Treatment options for bipolar disorder
Treating bipolar disorder often involves a combination of medications and therapy. A healthcare professional can work with you to put together a treatment plan that is suitable for your needs.
Medications that are commonly prescribed for mood changes in bipolar disorder include:
Mood stabilizers
Healthcare professionals often prescribe mood stabilizers to manage and prevent mood changes. They help regulate neurotransmitter activity to stabilize mood.
Some commonly prescribed mood stabilizers include:
- lithium (Eskalith)
- valproic acid (Depakene)
- lamotrigine (Lamictal)
