Mechanism

Synthesis from 1 study

How it works

Too much thyroid hormone overworks brain areas that control mood, changing how brain signals are sent and received. Even after the thyroid is fixed, those brain changes don't reverse, so anxiety and depression stay.

Most probable mechanism

In Simple Terms

Too much thyroid hormone overstimulates brain regions that control mood and stress, changing how brain chemicals work and how nerve cells connect. Even after thyroid levels return to normal, these brain changes stay, so anxiety and depression continue.

Causal chain
1

Excess thyroid hormone increases neuronal excitability in the amygdala and prefrontal cortex by enhancing glutamatergic transmission and reducing GABAergic inhibition.

2

Chronic overstimulation alters synaptic plasticity and downregulates serotonin and norepinephrine receptor density in limbic circuits.

3

Neurochemical and structural adaptations in mood-regulating networks persist after normalization of circulating thyroid hormone levels.
