Perimenopause is one of the most significant transitions a woman will go through during her life. It is often framed as a physical shift, with hot flushes, irregular periods, and disrupted sleep being classic signs. But, for many women, the mental health impact is far more disabling than night sweats or unpredictable periods. In many studies across different cultural groups, it is reported that during the perimenopause:
- the risk of new onset depression or relapse of depression increases substantially,
- suicide rates peak,
- those with severe mental illness such as schizophrenia, are at increased risk of relapse or treatment resistance, and
- PTSD symptoms may intensify compared to both pre- and post-menopausal periods.
Whilst there are now endless humorous Instagram reels about women having reduced tolerance for unsuspecting spouses during this life phase, the evidence points to something far more serious: perimenopause is a period of genuine vulnerability to significant mental health deterioration.
What makes this life phase so high risk for some women? During the perimenopause, which is the 4-10 years preceding the last menstrual period, hormone levels change. Broadly, testosterone declines steadily; progesterone declines but fluctuates until menopause is reached; and oestrogen levels fluctuate markedly before ultimately declining and stabilising after menopause. These hormones are not just reproductive, they are neuroactive.
The brain is highly sensitive to these hormonal shifts, and in turn, the hormones affect the neurotransmitter systems involved in mood regulation, cognition, and stress responsivity. As a result, women may experience changes in memory, emotional regulation, and resilience to stress. Importantly, these effects can emerge years before classic symptoms such as hot flushes, meaning women in their late 30s or early 40s may present primarily with psychological symptoms.
Depression in the perimenopause can manifest differently than at other life stages. Cognitive symptoms (e.g., brain fog and memory loss), plummeting self-esteem, and irritability and rage are more prominent. Paranoia (of the non-bizarre type) can also be part of perimenopausal depression, for example, thinking that she’s disliked by everyone in the workplace, or worrying that her spouse or children no longer love her.
It is not all women, of course, who will experience mental illness in the perimenopause. Women with a history of mental health difficulties, particularly those linked to hormonal sensitivity (such as severe premenstrual symptoms or postnatal depression), may be at increased risk of relapse. For others, the perimenopause may be the first time she experiences significant psychological distress or mental illness. Additional risk factors for perimenopausal depression include early menopause, neurodivergence, childhood trauma, and experiencing family violence.
Crucially, it is not only biological change that drives the experience of perimenopausal depression. The perimenopausal years often coincide with substantial psychosocial load: raising teenagers, empty nesting, or accepting (or rejoicing!) that the child bearing years are drawing to a close; caring for ageing parents who perhaps may have been the cause of the childhood trauma/neglect that led to her PTSD; and managing senior responsibilities at work. Sexual functioning can also be affected. Perimenopausal hormonal changes can result in a loss of libido, recurrent urinary tract infections and/or thrush, and vulva fissures (small splits in the folds of the skin of the vulva) that are so tender that wearing a pair of jeans is unbearable, let alone engaging in sexual activity.
The cumulative load of these changes in the perimenopausal woman’s whole being is enormous; no wonder it contributes in such a profound way to her mental health.
For women who are wondering whether they may be experiencing perimenopausal depression, completing a screening tool such as the Menopause Depression Scale (Meno-D) is an excellent starting place. Whilst the score itself is not a diagnosis, it gives language to what is happening and provides something concrete to take to her general practitioner.
Effective care requires a genuinely multidisciplinary approach: GPs, psychologists and medical specialists where required. Menopause hormone therapies (MHT) can be effective for mood and anxiety and can also help alleviate some of the contributing physical symptoms (e.g., hot flushes and genito-urinary symptoms). Antidepressants may be effective for some women, though the emotional blunting side effects can be problematic. Psychological support is vital; seeing a menopause-informed psychologist can assist with identity transitions, meaning-making, sleep and lifestyle interventions, and the processing of trauma that may have resurfaced.
Perimenopausal depression is common and can be debilitating, but it is also highly treatable with care is coordinated, nuanced, and addresses the whole woman.
