Oestrogen, progesterone, testosterone, thyroid hormones, and cortisol all directly modulate neurotransmitter systems — serotonin, GABA, dopamine, and noradrenaline. When these hormones decline or become imbalanced, mood disturbance often follows.
Perimenopausal depression is now recognised as a distinct clinical entity, with the perimenopausal transition representing a window of vulnerability for mood disorders. Oestrogen withdrawal reduces serotonin synthesis and receptor sensitivity. Progesterone decline removes GABA-ergic anxiolytic support. Low testosterone in both sexes is associated with depression and cognitive decline.
We work alongside your GP and mental health professionals to investigate the hormonal dimension of mood disturbance. Hormonal optimisation does not replace psychiatric care where needed, but it can be a powerful complement — and for some patients, the missing piece of the puzzle.
