What is the chemical imbalance that causes bipolar?

Bipolar disorder is widely believed to be the result of chemical imbalances in the brain. The chemicals responsible for controlling the brain's functions are called neurotransmitters, and include noradrenaline, serotonin and dopamine.

What is the main cause of bipolar disorder?

Genes. Bipolar disorder often runs in families, and research suggests that this is mostly explained by heredity—people with certain genes are more likely to develop bipolar disorder than others. Many genes are involved, and no one gene can cause the disorder. But genes are not the only factor.

What chemicals does bipolar effect?

The neurotransmitters that are implicated in bipolar illness include dopamine, norepinephrine, serotonin, GABA (gamma-aminobutyrate), glutamate, and acetylcholine.

Is Bipolar caused by hormone imbalance?

And female hormones and reproductive factors may influence the condition and its treatment. Research suggests that in women, hormones may play a role in the development and severity of bipolar disorder. One study suggests that late-onset bipolar disorder may be associated with menopause.

What happens in the brain with bipolar disorder?

Bipolar Disorder May Change Your Brain's Chemical Balance

Scientists believe the main neurotransmitters affected by bipolar disorder include: Noradrenaline or norepinephrine, which increases alertness, arousal, and speeds up your reaction time. The neurotransmitter also plays a role in your ability to concentrate.

Understanding Bipolar Disorder

What is the life expectancy of a person with bipolar disorder?

The authors found that the pooled life expectancy for patients with bipolar disorder, after removal of 1 outlier study, was 67.4 years (95% CI 65.2-69.7), with no evidence of publication bias. Life expectancy was significantly shorter in men (64.6) compared to women (70.5).

Does bipolar show up on brain scan?

New research revealed this month by the Westmead Institute for Medical Research shows that neurons located deep within the brain may offer a solution to the accurate diagnosis of bipolar disorder and depression.

Can low estrogen cause bipolar disorder?

Conclusion: These results indicate that estrogen fluctuations may be an important factor in the etiology of bipolar disorder and it is obvious that more research on this topic is needed to clarify the role of estrogen in women with bipolar disorder.

Can high testosterone cause bipolar?

Our findings are consistent with previous observations of the association between testosterone levels and parameters of mood and behavior. This study suggests that testosterone levels may be related to the course of bipolar disorder and suicidal behavior.

What are 5 signs of bipolar?

Is bipolar a dopamine disorder?

Abstract. Bipolar affective disorder is a common neuropsychiatric disorder. Although its neurobiological underpinnings are incompletely understood, the dopamine hypothesis has been a key theory of the pathophysiology of both manic and depressive phases of the illness for over four decades.

How do I know if I have a chemical imbalance?

The feeling of impending danger, distancing from others, and thoughts of hurting others or themselves are also common symptoms of chemical imbalances. Sometimes, people with chemical imbalances hear voices in their heads and are unable to carry out daily activities.

Does trauma cause bipolar disorder?

People who experience traumatic events are at higher risk for developing bipolar disorder. Childhood factors such as sexual or physical abuse, neglect, the death of a parent, or other traumatic events can increase the risk of bipolar disorder later in life.

Can too much dopamine cause mania?

Adrenaline is a close relative of dopamine. However, serious health problems can arise if too little or too much dopamine is being produced. If too few dopamine molecules are released, Parkinson's disease can develop, while an excess can lead to mania, hallucinations and schizophrenia.

How does serotonin affect bipolar disorder?

Dysfunction in serotonin neurotransmission is postulated to have a critical role in mood disorders. Serotonin transporters terminate serotonin's action by reuptake into neurons. In bipolar disorder, platelets have been shown to have lower serotonin reuptake.

Can childhood trauma cause bipolar?

Childhood traumatic events are risk factors for developing bipolar disorders, in addition to a more severe clinical presentation over time (primarily an earlier age at onset and an increased risk of suicide attempt and substance misuse).

Does testosterone help with bipolar disorder?

Psychiatric symptoms and disorders may be seen with the use of anabolic androgenic steroids in patient with bipolar mood disorder. Testosterone replacement therapy may cause poor adherence of bipolar mood disorder treatment and may trigger manic period.

Can testosterone make you manic?

Anabolic steroid hormones (like testosterone) can cause symptoms of mania, including agitation, irritability, suspiciousness, and even hallucinations.

Does menopause worsen bipolar?

Menopause has been shown to increase symptoms of bipolar disorder. Research suggests that women with bipolar disorder are more sensitive to hormonal shifts during menopause.

Does bipolar worsen with age?

Changes in the frequency and severity of episodes are among the most evident changes in bipolar disorder at an older age. Research suggests that older adults with bipolar disorder often experience: more frequent episodes. more depressive episodes and less time spent in manic or hypomanic states.

Can thyroid problems cause bipolar disorder?

Background. Both thyroid dysfunction and antithyroid antibodies have been widely reported to be associated with affective disorders. Cross-sectional [1, 2] or cohort studies [3, 4] have found that hypothyroidism increased risk of developing depression or bipolar disorder.

Are you born with bipolar?

Bipolar disorder is frequently inherited, with genetic factors accounting for approximately 80% of the cause of the condition. Bipolar disorder is the most likely psychiatric disorder to be passed down from family. If one parent has bipolar disorder, there's a 10% chance that their child will develop the illness.

Does bipolar damage the brain?

Brain Changes

Research shows bipolar disorder may damage the brain over time. Experts think it's because you slowly lose amino acids. They help build the proteins that make up the insulation around your neurons. Your frontal lobe also might not work as well.

Can you grow out of bipolar?

With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder. Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may outgrow the disorder by the time they reach 30.

How does dopamine affect bipolar disorder?

Puzzlingly, pharmacological evidence shows that both dopamine agonists and antidopaminergics can improve bipolar depressive symptoms and perhaps actions at other receptors may reconcile these findings.
