Synthesis from 1 study

How it works

Too much thyroid hormone makes the brain's stress system too active and messes up the chemicals that keep mood stable. This causes people to feel more anxious, depressed, and overwhelmed by stress.

Most probable mechanism

In Simple Terms

Too much thyroid hormone overstimulates the brain's stress system and disrupts chemicals that control mood, leading to increased anxiety and depression.

Causal chain

Elevated circulating thyroid hormones increase central nervous system sensitivity to corticotropin-releasing hormone and adrenocorticotropic hormone

Indirect evidence only

which leads to

Excess thyroid hormone enhances norepinephrine release and reduces serotonin reuptake in limbic and cortical brain regions

Indirect evidence only

which leads to

Sustained noradrenergic overactivity and serotonergic imbalance amplify amygdala reactivity and impair prefrontal cortical regulation of emotional responses

Indirect evidence only

which leads to

Chronic activation of the hypothalamic-pituitary-adrenal axis and monoaminergic systems increases physiological and behavioral responses to environmental stressors

Similar Assertions

People with an overactive thyroid show higher rates of anxiety, depression, and stressful life events than people with normal thyroid function.

99%

People with an overactive thyroid have higher levels of anxiety and depression than people with normal thyroid function, even when accounting for how often they see a doctor.

93%

People with hyperthyroidism have higher levels of anxiety and depression than people with normal thyroid function or no thyroid condition.

91%

People diagnosed with hyperthyroidism report more stressful life events than people with normal thyroid function or no thyroid condition.

89%

In people with hyperthyroidism, anxiety and depression symptoms occur independently of thyroid hormone levels, suggesting other biological, immune, or social factors are involved.
