It felt as though my thoughts were buried beneath layers of clutter and debris.

One evening on a Friday, while my husband and I were deciding on a dinner spot, our exchange unfolded in a familiar yet frustrating pattern:

Me: Would you like to head to that particular eatery?

Him: Which one are you referring to?

Me: The name is escaping me right now. We've dined there previously. It's the spot with peanut shells scattered across the floor. It's located beside... you know the place. It's along that street where we used to bring the dog for veterinary check-ups. Does that ring a bell??

It was like specific details were trapped in a thick, murky sludge deep within my mind. Then, much later, perhaps hours afterward, the recollection would surface, and I'd exclaim to an empty space...

“Texas Roadhouse!”

Challenges with recalling proper names are common among middle-aged individuals and older adults.

That said, the issues I was encountering, which intensified during my late 40s and into my early 50s, seemed anything but ordinary.

Not just struggling to recall names of restaurants, acquaintances, books, films, or countless other items, my cognitive functions were faltering even during professional hours.

I'd position myself in front of the computer display, gaze at an open document, and try to compel my fingers to produce something meaningful. A pervasive haziness enveloped everything, reminiscent of those initial groggy moments upon waking when you've silenced the alarm but remain too drowsy for simple calculations.

I experienced brighter periods, typically in the mornings, squeezing as much writing as possible into the limited two or three hours of clear thinking I could muster.

Yet on my most challenging days, I woke enveloped in a persistent fog that refused to lift. Productivity at work became impossible. I lacked the mental capacity for reading or any substantial activities.

I turned to medical professionals for guidance.

Three different practitioners suggested antidepressants. I experimented with one, only to feel even more subdued. Another attempt followed, then a third at an elevated dosage. Regardless, I resembled a zombie in my responsiveness. A separate expert prescribed a sleep aid, which intensified the drugged sensation.

Thyroid function was examined—perfectly normal. No signs of anemia either. I sampled various supplements, mushroom-infused coffee, and nearly every product promising enhanced cognition through labels touting “think” or similar buzzwords.

After almost two years cycling through numerous specialists, I scheduled my annual gynecological examination. Casually mentioning vaginal dryness prompted a series of inquiries unrelated to that concern: How was my sleep quality? What about my emotional state? Energy levels? Any hot flashes? And brain fog?

“It's intriguing you bring up brain fog,” I replied in my characteristic foggy drawl. “I feel scarcely functional.”

By the appointment's conclusion, clarity emerged: depression had likely never been the issue.

The reality was menopause.

My gynecologist provided prescriptions for estradiol and progesterone upon my departure.

Almost immediately, it was like a light switched on in my mind.

Thinking became feasible once more. Typing flowed effortlessly. Conversations held my attention. Work extended beyond midday.

Moreover, for the first time in years, uninterrupted sleep stretched beyond a mere two hours.

Menopause does not qualify as a medical ailment.

It is not classified as a disease either.

Rather, akin to puberty, it represents a natural phase of life—a specific transitional period, to be exact.

Menopause is officially achieved after 12 continuous months without menstruation. From that point, you enter the postmenopausal stage.

As women near this transition, hormonal concentrations shift dramatically and decline, sparking a wide array of symptoms. Issues like weight gain and diminished libido often dominate discussions.

Nevertheless, approximately 40 percent of women during and post-menopause describe heightened irritability, emotional volatility, anxiety, exhaustion, and difficulties with focus, per insights from the American College of Obstetricians and Gynecologists.1 2 The accompanying graph illustrates this as one of the most susceptible periods for depression in women,3 especially those with prior history.

Prior to hormone therapy, uncontrollable tears would strike without provocation. At other times, everyday environmental stimuli overwhelmed me excessively.

Ordinary noises—such as vehicular hum or mall chatter—physically pained me. I became easily startled, short-tempered, and anxious over previously trivial matters, like traversing bridges or navigating construction zones.

The precise causes of these cognitive and emotional disturbances remain somewhat elusive.

Hormonal fluctuations undoubtedly contribute, alongside standard brain alterations associated with advancing age.

Compounding this, women in this life phase frequently juggle multiple demands that rapidly deplete mental resources, much like a voracious entity sapping vital essence.

In their 40s and 50s, many attain career pinnacles, with obligations spilling into home life and disrupting rest. They might manage moody adolescents, support elderly relatives, adapt to children leaving home, reassess partnerships, or grapple with financial shocks from tuition bills or medical invoices.

Yet, a less discussed catalyst for cognitive woes stems not from chronological aging or external pressures but directly from the iconic menopausal hallmark: hot flashes.

Understanding the mechanics of a hot flash

Daytime hot flashes and nocturnal night sweats are grouped as vasomotor symptoms. (Vasomotor pertains to blood vessel narrowing or widening, impacting aspects like blood pressure and perspiration.)

In a hot flash or night sweat episode, norepinephrine and cortisol surge. Vessels expand to dissipate heat. Blood pressure and pulse elevate.

Severity varies; skin may flush as heat radiates across face, neck, and torso.

Sweating, palpitations, anxiety, fatigue, or dizziness might ensue.4

The emergence of hot flashes near menopause lacks full explanation.

One prevailing hypothesis posits that declining estrogen disrupts the hypothalamus, the brain region governing thermoregulation. This internal gauge malfunctions, misinterpreting body temperature as excessively high or low erroneously.

Impacts of vasomotor symptoms on cerebral function

Historically, experts dismissed vasomotor symptoms as minor nuisances or social embarrassments.

(Truthfully, I shared that view. Across those futile consultations, hot flashes never crossed my mind to disclose.)

Emerging evidence, however, indicates hot flashes transcend discomfort or laundry hassles, potentially harming vascular and neural health adversely.5 Consequently, **more specialists now view vasomotor symptoms as legitimate treatable disorders.**6 7 8

Hot flashes linked to cerebral lesions

A study involving 226 women equipped them with hot flash monitors. They underwent MRI scans, maintained sleep logs, and wore devices tracking nocturnal arousals.9

Analyzing scans from those with highest hot flash frequency revealed numerous irregular patches termed whole-brain white matter hyperintensities.

Formerly deemed normal aging markers, these hyperintensities now signal heightened dementia risk (doubled) and stroke susceptibility (tripled).10

Connection through vascular changes

These hyperintensities may arise partly from alterations in cerebral blood supply vessels.

A longitudinal three-year analysis of 492 women confirmed **frequent hot flash sufferers exhibited vascular deteriorations, like impaired dilation for blood flow needs.**11

Further studies associate recurrent hot flashes with elevations in:

• Carotid artery wall thickening supplying brain, face, neck12
• Body fat accumulation
• Total and LDL cholesterol levels
• Insulin resistance13 14 15 16

Disrupted sleep as a mediator

Beyond direct vascular effects, hot flashes indirectly impair the brain via sleep fragmentation.17

Remarkably, numerous women remain unaware hot flashes interrupt slumber.

They might attribute awakenings to insomnia or apnea, as I did initially.

Night sweats need not involve profuse perspiration always.

By arousal from cortisol/norepinephrine spikes, the heat may have subsided, mimicking random wakings repeatedly.

Such disruptions hinder memory consolidation, toxin clearance, and retention of daily information like names and dates.

They compromise hippocampal connectivity vital for learning/memory.

Sleep deficits hyperactivate the amygdala for emotions, amplifying stress, anxiety, irritability, frustration, rage.18 19

These shifts manifest after mere days to a week of deprivation—consider chronic multi-year patterns.

Barriers to obtaining appropriate support

Depression diagnosis relies on the Patient Health Questionnaire (PHQ-9). Endorsing four of nine symptoms flags depression.

Yet four overlap with menopause-induced sleep loss:

• Diminished interest/pleasure in activities
• Difficulties initiating/maintaining sleep
• Fatigue/low energy
• Concentration struggles, e.g., reading/TV

Endorsing these could yield depression label despite root in post-47 sleep battles.

Insufficient specialized education

Surveys reveal **80 percent of residents feel marginally equipped for menopause discussions.**20 Even ob-gyn programs rarely include it.21

Thus, fatigue/focus complaints rarely prompt hot flash/sleep queries.

Even recognizing vasomotor roots, many clinicians avoid menopausal hormone therapy (MHT/HRT), deeming it unsafe/risky.

This reflects “defensive medicine,” per menopause expert Jerrold H. Weinberg, MD.

“Doctors instinctively prioritize litigation fears in recommendations,” notes Dr. Weinberg.

Actual evidence on hormone therapy safety

Concerns trace to dated studies tying specific hormones to minor breast cancer/stroke upticks.22

Contemporary data nuance this: risks hinge on age, dose, formulation, duration.23 24

**For those under 60 and within 10 postmenopausal years with severe symptoms, benefits eclipse risks.**25

Benefits include lowered Alzheimer’s/osteoporosis odds, affirming net positives for most, says Dr. Weinberg.

Antidepressants aid mood/sleep/hot flashes alternatively, with side effects, but appear less litigious.

Strategies for effective health advocacy

For endless menopause specialist searches (self/clients), heed Dr. Weinberg and Helen Kollias, PhD (physiology/molecular biology expert, Precision Nutrition/Girls Gone Strong advisor):

▶ Consult menopause-certified providers.

They highlight training in bios, e.g., menopause focus. Use Menopause Society directories for certified lists.

▶ Log symptoms meticulously.

Notes combat appointment fog/nerves; track efficacy for adjustments.

Monitor:

• Hot flash frequency
• Daily brain fog hours
• Fatigue/anxiety/rage incidences
• Nocturnal awakenings

▶ Provide precise details.

“Poor sleep” pales vs. “Past week: one 4-hour block; average 5 wakings/night; max stretch 3 hours.” Share smartwatch data.

▶ Discuss treatment trade-offs openly.

“Shared decision-making” fosters benefit/risk dialogues, curbing defensiveness, reducing complaints/suits.29 30

Sample queries:

• “Could MHT suit me? Let's evaluate candidacy.”
• “MHT's breast cancer link concerns me. Assess my risk via history/age/weight/lifestyle?”
• “Family osteoporosis/dementia history; MHT aids sleep/risks? Weigh options?”

Enhancing mental/emotional well-being in menopause: 9 practical approaches

Habits boosting mental/emotional health midlife mirror general wellness pillars across ages/lifestages.

No unique vasomotor diet exists beyond skipping caffeine/alcohol/spicy/hot items. (Soy like tofu aids less than hyped,30 yet nutritious.)

Approach #1: Prioritize core wellness foundations.

Midlife basics persist: nutrition/activity/stress/sleep/connections/purpose.

Amplified importance now. Reflect:

• Sufficient sleep/rest allocation?
• Regular movement?
• Diet emphasizing unprocessed colorful produce/healthy fats/lean proteins/fiber/legumes?
• Supportive human interactions buffering stress?
• Awe/joy/curiosity/peace/purpose infusions?

“No” answers? Probe barriers, eliminate, bolster support.

Approach #2: Trial creatine supplementation.

Beyond muscle/bone preservation amid age/hormones, creatine uplifts mood/brainpower, curbs fatigue, offsets sleep loss.32 33 5-7g daily monohydrate suffices.

Approach #3: Consistent light exposure routines.

Sunlight boosts alertness, synchronizes circadian rhythm for evening drowsiness/morning vigor. Morning/late afternoon optimal.

In 103-person study, AM sun correlated to superior sleep: faster onset, duration, fewer disruptions.34 Mood/concentration gains too.35

Approach #4: Moderate gym intensity.

Exhaustion plus prolonged/intense sessions exacerbate woes.

Midlife injury risk rises; recovery prolongs vs. youth.36 Overstacking yields aches/irritability/tension/fatigue.

Conversely, brief exertions like cold plunges invigorate daytime alertness.

Desk drowsing? Opt 5-10min outdoor walks/pushups/squats.

Pre-bed gentle yoga/stretching relaxes sans adrenaline surge.

Attune to bodily signals post-poor sleep.

Vigorous/PR pursuits viable, balanced with moderation/recovery scaled to status.

Swap intense run for zone 2; trim resistance sets/reps/volume.

Approach #5: Explore CBT-I for insomnia.

Evidence-based CBT-I builds sleep skills/reframes, e.g., fixed wake times irrespective of prior night.

Approach #6: Confront stress realistically.

Energy/desire wanes for past overloads. Audit time/bandwidth days-long; scrutinize.

Queries:

• Desired time/energy use?
• Schedule permits self-rest/recovery or others-dominated?
• Rest-prioritizing shifts?

Coaches: Employ Wheel of Stress for stressor pinpointing.

Interpersonal demands? Learn “no” boundaries.

Approach #7: Test cooling aids.

Cooler sleep setups cut sweats/improve rest: lower thermostat/fan/cooling pad.

Approach #8: Embrace breaks liberally.

Foggy suboptimal work anyway. Sanction 20min idles:

• Cold drink relaxation
• Pet cuddles
• Window gazing
• Outdoor bird-listening
• Friend calls

Quick reset: 5min body-mind scan.

Comfort pose (legs-up-wall/pillow-knees). Eyes shut, sense from head-to-toe. Observe neutrally. Note physical/emotional/thought states post-scan.

Approach #9: Adopt circulation-supportive nutrition.

Heart vessel protectors shield brain too. MIND/Mediterranean patterns lower Alzheimer’s/depression risks37 38—veggies/fruit/grains/olives/beans/fish/whole foods.

Nitrate sources (beets/leafy greens) dilate vessels, transiently boosting brain bloodflow/memory.39 40

Menopause's silver lining

Frustration mounts when capacities shrink.

I empathize deeply.

Yet this phase unveils opportunity: compelling priority realignment.

Prior to hormones, capabilities felt profoundly curtailed.
