Many women are surprised to learn that anxiety and mood changes can be early signs of perimenopause.
Fluctuating estrogen levels can influence neurotransmitters in the brain that regulate mood, including serotonin and dopamine. As a result, some women may experience:
• new or worsening anxiety
• irritability or mood swings
• increased stress sensitivity
• nighttime anxiety or sleep disruption
These symptoms may occur even before classic menopause symptoms such as hot flashes appear.
