Key Takeaways
- ✓Head Protection as Priority One: Traumatic brain injury is a modifiable Alzheimer's risk factor, particularly for APOE4 carriers. Lugavere quit boxing after a single sparring session, redirecting to resistance training and walking. Contact sports that risk repeated head impact warrant serious reconsideration for anyone with a family history of dementia or known genetic risk factors for neurodegeneration.
- ✓Glymphatic Cleaning During Sleep: A recently published study confirmed a functioning glymphatic system in humans, where the brain flushes amyloid proteins into cerebrospinal fluid during sleep. This process accelerates at night but also benefits from exercise during the day. Targeting six to nine hours of consistent sleep, supported by magnesium and 3g of glycine, optimizes this clearance mechanism.
- ✓Anticholinergic Medications and Dementia Risk: First-generation antihistamines like diphenhydramine (Benadryl) and Unisom cross the blood-brain barrier and carry documented dementia risk with chronic use. Occasional use poses minimal concern, but daily use over years should be avoided. Newer-generation alternatives — Claritin, Zyrtec, Allegra — do not carry the same risk and are safer for regular allergy management.
- ✓B Vitamins for High Homocysteine: The VitaCOG trial found that a B-complex containing folate, B6, and B12 reduced brain atrophy by up to 50% in mild cognitive impairment patients with elevated homocysteine. The effect was strongest in those with adequate omega-3 status. Getting homocysteine tested and supplementing if levels exceed roughly 10 µmol/L represents a targeted, low-cost intervention.
- ✓Omega-3 DHA and Alzheimer's Risk Reduction: Adults in the highest quintile of red blood cell DHA levels show approximately 50% lower Alzheimer's disease risk in observational data. Roughly 80% of U.S. adults under-consume omega-3s. Targeting 1–2g combined EPA and DHA daily from IFO-certified, triglyceride-form fish oil addresses this gap, particularly for those eating fewer than two servings of fatty fish weekly.
What It Covers
Max Lugavere answers listener questions on brain health, covering his five non-negotiable dementia prevention habits, evidence-based supplements including omega-3s, creatine, and B vitamins, early cognitive decline warning signs, the safety of anticholinergic allergy medications, erythritol concerns, and how to evaluate protein powders for quality and leucine content.
Key Questions Answered
- •Head Protection as Priority One: Traumatic brain injury is a modifiable Alzheimer's risk factor, particularly for APOE4 carriers. Lugavere quit boxing after a single sparring session, redirecting to resistance training and walking. Contact sports that risk repeated head impact warrant serious reconsideration for anyone with a family history of dementia or known genetic risk factors for neurodegeneration.

Targeting 1–2g combined EPA and DHA daily from IFO-certified, triglyceride-form fish oil addresses this gap, particularly for those eating fewer than two servings of fatty fish weekly.
- •Cognitive Decline Warning Signs: Normal aging includes tip-of-the-tongue forgetfulness that resolves later. A meaningful red flag is when a spouse or close observer notices a change in memory or language ability — difficulty finishing sentences or word retrieval that differs from a person's baseline. Self-noticed changes also warrant neurologist evaluation. Forgetting where keys are is normal; forgetting what keys do is not.
Notable Moment
During a discussion on supporting a loved one with cognitive decline, Lugavere introduced the concept of therapeutic fibbing — the counterintuitive practice of not correcting a person with dementia. Attempting to redirect their thinking can function as a stressor, while compassionately going along with their reality reduces distress and reflects more effective caregiving.
