Photobiomodulation and the Menopausal Brain
Feeling forgetful or fuzzy-headed as menopause approaches? Many women notice “brain fog” during this time - struggling to remember names, recall appointments, or multitask. These changes, though common, are sometimes part of a medically recognized condition called mild cognitive impairment (MCI). But before you go off down the rabbit hole of Dr. Google - The good news is PBM is offering new hope for protecting and even enhancing memory and thinking at midlife (and beyond).
What Is Mild Cognitive Impairment (MCI)?
MCI represents a gray area between normal aging and dementia, with measurable changes in memory and executive function, but no major disruption to daily life. For women around menopause, hormonal changes, particularly estrogen drop - can make the brain more sensitive to these shifts. While MCI doesn’t mean dementia will definitely follow, it signals the need for careful attention to our brain health.
Laser Therapy: A Gentle New Option
A recent study tested transcranial photobiomodulation (tPBM)using gentle, near-infrared laser light on middle-aged adults living with MCI. Light at a wavelength of 810 nm and power density of 250 mW/cm² was shined on the forehead for 8 minutes per session, 3 times per week, for 4 weeks (12 sessions total). The treatment was painless, non-invasive, and drug-free - the kind of innovation many women want.
How Did Researchers Measure Success?
Improvements weren’t judged just by how participants felt. Rigorous testing covered:
· Visual working memory (how well participants could remember visual sequences)
· Auditory working memory (recalling numbers forwards and backwards)
· Executive function (skills like planning, organizing, and managing emotions)
· Self-reported sleep quality
Women (and men) who received the laser therapy scored meaningfully higher on memory and executive function tests after the treatment, though these gains faded after about a month, suggesting regular sessions may be needed. Interestingly there was no notable effect on sleep quality.
What You Can Do Now: Science-Backed Advice
While laser therapy for MCI is still in clinical trials, there are proven strategies that help protect women’s brain health during menopause and beyond:
1. Prioritize Sleep
· Aim for 7–8 hours of quality sleep; stick to a regular sleep schedule.
· Treat sleep problems (like insomnia or sleep apnea). Good sleep is vital for memory consolidation.
2. Stay Mentally Active
· Try puzzles, word games, learning new skills, and social connection.
3. Move Your Body
· Regular aerobic and strength exercise boosts blood flow and supports healthy brain cells.
4. Eat for Your Brain
· Diets rich in leafy greens, berries, fish, nuts, and olive oil are linked to lower dementia risk.
· Avoid sugar and processed foods.
5. Consider Evidence-Based Supplements (With Doctor Guidance)
· Omega-3 fatty acids (from fish oil), vitamin D, and B vitamins may support brain health - but results are mixed, and individual needs vary.
· Herbal products (ginkgo, turmeric, etc.) are popular, but should be used with caution; research is ongoing and some supplements interact with other medications.
6. Manage Stress and Hormonal Health
· Mindfulness, yoga, and other relaxation techniques support cognitive and emotional wellness.
· For some, hormone therapy may be appropriate, after weighing risks and benefits with a qualified healthcare provider.
7. See a Memory Specialist Early
· If memory changes are worrisome or affecting daily life, prompt evaluation helps clarify causes and opens up more options for support.
Menopausal brain fog and memory changes can be tough—but they’re not signs of weakness, nor are they inevitable. New therapies like tPBM offer gentle, non-invasive promise, while lifestyle strategies remain a powerful foundation for women’s brain health. By sleeping well, staying active, nourishing the body and mind, and keeping up with scientific breakthroughs, women can move through menopause with less stress.
