Bipolar disorder, formerly known as manic depression, is a mental health condition characterized by extreme shifts in mood and energy levels. People with bipolar disorder experience alternating episodes of mania (elevated moods and energy) and depression (low moods and energy). One of the more perplexing symptoms associated with bipolar disorder is hearing voices when no one is talking.
What are the key symptoms of bipolar disorder?
The main symptoms of bipolar disorder include:
- Manic episodes – characterized by elevated, expansive, or irritable moods; increased activity and energy; impulsiveness; racing thoughts; diminished need for sleep; grandiose sense of self; being more talkative than usual; and engaging in risky behaviors
- Hypomanic episodes – similar to manic episodes but less severe
- Depressive episodes – characterized by depressed mood; diminished interest in activities; changes in appetite and sleep; fatigue; feelings of worthlessness or guilt; difficulty concentrating; and suicidal ideation
- Mixed episodes – having both depressive and manic symptoms at the same time
In addition to these core mood symptoms, people with bipolar disorder may also experience psychotic symptoms like hallucinations or delusions during manic, hypomanic, or mixed episodes. Hearing voices or sounds that aren’t there is one example of an auditory hallucination that can occur.
Do all people with bipolar disorder hear voices?
No, not all people with bipolar disorder hear voices or experience auditory hallucinations. Here are some key points on this symptom:
- Studies estimate that about 50-70% of people with bipolar disorder experience psychotic symptoms like hallucinations at some point, often during manic or mixed episodes.
- However, the prevalence varies widely – some studies have found rates as low as 10% while others are as high as 90%.
- When psychotic symptoms do occur in bipolar disorder, auditory hallucinations like hearing voices are more common than visual hallucinations.
- People with bipolar I disorder (who have full manic episodes) are more likely to experience psychotic symptoms than people with bipolar II disorder (who have hypomania but not full mania).
- Not everyone hears voices – some may experience other types of hallucinations like seeing things that aren’t there.
- Psychotic symptoms tend to be temporary and occur around mood episodes, as opposed to being persistent.
So in summary – while many people with bipolar disorder do experience hearing voices at some point, not all of them do. The prevalence ranges widely based on the type of bipolar disorder and other factors.
What do the voices sound like?
The voices heard by people with bipolar disorder can vary in terms of:
- Loudness – some hear faint, whispering voices while others hear voices shouting loudly
- Clarity – voices may be clear anddistinct or muffled and indistinct
- Number of voices – some people hear a single voice, while others hear multiple voices talking at once
- Identity – voices may sound like the voice of someone familiar or be unrecognizable
- Content – voices may have conversations, comment on theperson’s behavior, give commands, or make threats
The specific qualities of the voices can help mental health professionals determine possible diagnoses and treatments.
What causes people with bipolar to hear voices?
There are several possible explanations for why some people with bipolar disorder hear voices:
- Hyperactivity in the brain – Manic episodes are characterized by high energy and racing thoughts, which correspond to more activity in brain regions like the subcortex. Hyperactivity in these areas may lead to overstimulation that the brain interprets as voices.
- Neurotransmitter imbalances – Changes in chemicals like dopamine and serotonin during mood episodes may affect parts of the brain involved in psychosis and perception.
- Sleep deprivation – Lack of sleep, common in mania, can trigger psychotic symptoms like hallucinations.
- Medication effects – Some bipolar disorder medications like antidepressants and stimulants can themselves provoke psychotic symptoms.
- Substance use – Drugs and alcohol, which are common during manic episodes, can induce psychosis.
- Genetics – There may be shared genetic risk factors for bipolar disorder and schizophrenia, the latter of which is characterized by psychosis.
- Brain changes – Structural and functional changes in certain brain regions could make people with bipolar disorder more vulnerable to hallucinations.
In many cases, there may be multiple contributing factors to psychotic symptoms in an individual rather than a single cause.
Are the voices real?
The auditory hallucinations experienced in bipolar disorder are generally not “real” in the sense that they do not represent actual external sounds or voices of people who are present.
However, the voices can feel extremely real to the person experiencing them. In some cases, people may be unable to distinguish the voices from actual sounds in their environment.
At the same time, these hallucinations are real psychiatric symptoms with complex biological and psychological underpinnings. Dismissing them as not real can invalidate the sufferer’s experience.
When do people with bipolar disorder hear voices?
Psychotic symptoms like hearing voices tend to occur during specific types of mood episodes in bipolar disorder:
- Manic episodes – Mania often triggers hallucinations and delusions.
- Mixed episodes – The combination of mania and depression can provoke psychosis.
- Severe depressive episodes – Major depression occasionally precipitates hallucinations.
- Hypomanic episodes – Hypomania may prompt mild psychotic symptoms in some cases.
People generally do not hear voices or experience other psychotic symptoms when their mood is stable, such as during euthymia. The hallucinations tend to be tied to mood disturbances.
Are voices dangerous?
Hearing voices can sometimes lead to dangerous behavior in people with bipolar disorder. Potential risks include:
- Following commands from threatening or derogatory voices, including harming oneself or others.
- Doing reckless things due to voices making grandiose promises or dare-like commands.
- Severely disrupting life activities due to acting out in response to voices.
- Misusing drugs, alcohol, or medications in an attempt to numb or quiet voices.
However, not all voice-hearing experiences are necessarily harmful – sometimes the voices are neutral or even benign. The risks depend on the nature of the voices and how the person responds to them.
How are voice hallucinations treated?
Treatment approaches for voice-hearing in bipolar disorder include:
- Mood-stabilizing medication – Drugs like lithium, anticonvulsants, and atypical antipsychotics can reduce psychotic symptoms by controlling manic/mixed episodes.
- Addressing sleep – Getting regular sleep can diminish hallucinations. Sleep medications may help.
- Psychotherapy – Cognitive behavioral therapy helps patients cope with disturbing voices and reduce associated distress.
- Coping strategies – Stress management, ignoring benign voices, social support, and distracting activities can help manage symptoms.
- Avoiding triggers – Preventing illicit drug use, sleep deprivation, and medication noncompliance can prevent psychosis.
The overall goal is stabilizing moods to minimize episodes of mania/hypomania where psychosis can occur. Supportive therapies and lifestyle changes also facilitate recovery.
What’s the outlook for voice-hearing with bipolar disorder?
The prognosis for hallucinations occurring in bipolar disorder is generally positive, especially with proper treatment. Key points about the outlook include:
- Most people experience an eventual resolution of psychotic symptoms when their mood episode ends.
- With medications and therapy, many find voices become less frequent, distressing, and intense over time.
- Learning coping strategies allows many people to manage voices and limit associated risks.
- Functioning can improve significantly after voices dissipate, though some minor issues may remain.
- Coexisting conditions like anxiety, PTSD, or alcohol misuse may worsen long-term prognosis.
- Adherence to a treatment plan is critical for sustained remission of symptoms.
While voice-hearing can be disruptive, scary, and difficult to treat, many people with bipolar disorder find it manageable, especially within the context of a comprehensive treatment plan.
Conclusion
In summary, psychotic symptoms like hearing voices are relatively common in people with bipolar disorder, reported in 50-70% of patients. However, not all people with bipolar disorder experience hallucinations. When present, the voices are usually tied to mood episodes such as mania and tend to improve as mood is stabilized with medication and therapy. While concerning, voice-hearing in mood disorders often responds well to treatment. With a combination of medications, lifestyle changes, and coping strategies, many people with bipolar disorder are able to manage intermittent hallucinations as part of their condition.
