How does perimenopause impact anxiety levels?

Impact of Perimenopause on Anxiety

Perimenopause significantly increases the risk of anxiety disorders, with women experiencing low anxiety at premenopause being 1.56-1.61 times more likely to develop high anxiety during early or late perimenopause or postmenopause, independent of other risk factors. 1

Physiological Mechanisms

• Hormonal fluctuations during perimenopause affect neurotransmitter systems involved in mood regulation:
  • Estrogen decline impacts serotonin, norepinephrine, and dopamine levels
  • Fluctuating hormone levels affect the hypothalamic-pituitary-adrenal axis, influencing stress response
  • These neurobiological changes can trigger or exacerbate anxiety symptoms

Epidemiology and Prevalence

• Recent global data shows increasing burden of anxiety disorders during perimenopause:
  • Global age-standardized disability-adjusted life year rate increased from 625.51 to 677.15 between 1990-2021 2
  • Projections suggest a 40.67% increase by 2035 compared to 2021 levels 2
  • Prevalence of anxiety in perimenopausal women is approximately 12.62% 3

Risk Factors for Perimenopausal Anxiety

• Pre-existing factors:

  • History of anxiety or depression
  • Family history of mood disorders
  • Trait anxiety and neuroticism
  • Adverse childhood experiences 4

• Concurrent factors:

  • Vasomotor symptoms (hot flashes, night sweats)
  • Sleep disturbances
  • Stressful life events
  • Chronic stress 4
  • Disharmonious family relationships 3
  • Irregular menstruation 3

Protective Factors

• Social support systems
• Resilience characteristics
• Higher income and better medical insurance 4, 3

Clinical Presentation

• Anxiety symptoms may manifest as:

  • Excessive worry
  • Irritability
  • Sleep disturbances
  • Difficulty concentrating
  • Physical symptoms (palpitations, shortness of breath)
  • Panic attacks

• Important distinction: Women with high anxiety at premenopause tend to maintain high anxiety throughout the menopausal transition, while women with low baseline anxiety are more vulnerable to developing new anxiety during perimenopause 1

Management Approaches

Non-Hormonal Approaches (First-Line)

• Psychological interventions:

  • Cognitive behavioral therapy
  • Mindfulness meditation
  • Hypnosis 5

• Pharmacological options:

  • SSRIs/SNRIs (venlafaxine, paroxetine, desvenlafaxine)
  • Gabapentin
  • Clonidine 5

Hormonal Therapy Considerations

• For women with moderate-severe anxiety symptoms not responding to non-hormonal approaches:

  • Transdermal estradiol is preferred over oral formulations (better safety profile) 5
  • If patient has intact uterus, progesterone is essential (micronized progesterone 200mg daily recommended) 5
  • No progestogen needed in post-hysterectomy patients 5

• Contraindications for HRT include:

  • History of hormone-related cancers
  • Active liver disease
  • History of abnormal vaginal bleeding
  • Previous venous thromboembolism or stroke
  • Coronary heart disease 5, 6

Monitoring and Follow-up

• Initial evaluation at 3 months after starting therapy
• Annual follow-up thereafter
• Assessment should include:
  • Symptom control
  • Blood pressure
  • Weight
  • Bleeding patterns 5

Important Clinical Considerations

• The relationship between perimenopausal syndrome and mood disorders (including anxiety) is strong and positive 3
• For mild depressive symptoms, estrogen alone may improve mood, but moderate to severe depression requires antidepressant therapy 7
• Women should be informed that anxiety symptoms often decrease at the end of menopause 7
• Regular weight-bearing exercise, maintaining healthy weight, smoking cessation, and lifestyle interventions are recommended as complementary measures 5

By understanding the complex interplay between hormonal changes and anxiety during perimenopause, clinicians can better identify at-risk women and implement appropriate interventions to improve quality of life during this transitional period.
