Key Wellness & Self-Care / Productivity Strategies (Medication-Related)

  • Do a proactive “medication review”

    • Sit down with a doctor or pharmacist and review every prescription, OTC medication, and supplement.
    • Add up your total anticholinergic burden (use available scoring tools).
    • Only reduce or stop meds under medical supervision—don’t quit abruptly.

  • Use label-reading & habit awareness to prevent “silent” cognitive decline

    • Read labels for items marked PM/nighttime/allergy relief—these are commonly anticholinergic.
    • Don’t assume OTC = safe for memory.

  • Ask targeted questions at appointments

    • If you’re on a medication associated with cognitive decline, ask:
      • Why it was started
      • Whether it’s truly necessary or just used for convenience
      • Whether there’s a safer alternative
      • Whether you can use the lowest effective dose for the shortest duration

  • Taper carefully when discontinuing sedatives

    • If using benzodiazepines, don’t stop suddenly—work with your doctor to taper over weeks/months due to risk of rebound (anxiety/insomnia) and agitation.

  • Prefer cognitive-friendlier alternatives when possible

    • Swap potentially risky options with alternatives that avoid the same brain chemistry pathways (especially acetylcholine blockade).

Medication Categories Most Tied to Rapid Memory Loss (Top 9)

9. Diphenhydramine (Benadryl) — anticholinergic OTC sleep/allergy drug

  • Wellness strategy: check OTC “sleep/PM/allergy” labels; consider alternatives like loratadine (Claritin) if appropriate.

8. Proton pump inhibitors (PPIs) — e.g., omeprazole (Prilosec), esomeprazole (Nexium)

  • Wellness strategy: if taken daily long-term, discuss with a doctor about:
    • Tapering to H2 blockers (e.g., famotidine/Pepcid)
    • Using the lowest dose for the shortest time
    • Possible symptom supports like deglycyrrhizinated licorice (claimed to be lower cognitive impact)

7. Oxybutynin (Ditropan) — anticholinergic bladder drug

  • Wellness strategy: if you notice memory slipping, bring it up; consider mirabegron (Myrbetriq) as an alternative pathway that doesn’t block acetylcholine.

6. Statins — e.g., simvastatin (Zocor), atorvastatin (Lipitor)

  • Wellness strategy: if cognitive “fog” appears after years on statins, discuss:
    • Dose reduction or a switch (the video suggests pravastatin or rosuvastatin as less brain-penetrating)

5. Benzodiazepines — e.g., lorazepam (Ativan), diazepam (Valium), alprazolam (Xanax)

  • Wellness strategy:
    • Don’t stop abruptly if used more than a few weeks
    • Request a gradual taper plan
    • Ask about alternatives such as buspirone or insomnia/anxiety talk therapies

4. Amitriptyline (Elavil) — anticholinergic used for pain/sleep/migraines

  • Wellness strategy: discuss alternatives depending on the indication:
    • Nerve pain: duloxetine or gabapentin
    • Sleep: melatonin or very low-dose doxepin
    • Mood disorders: SSRIs like sertraline or escitalopram

3. Paroxetine (Paxil) — SSRI with strong anticholinergic activity

  • Wellness strategy: in older adults, consider switching away if possible (video suggests sertraline or escitalopram), and consider support like B vitamins (B12/B6) as relevant.

2. Antipsychotic medications — e.g., quetiapine (Seroquel), risperidone (Risperdal), olanzapine (Zyprexa)

  • Wellness strategy:
    • Ask why it was started and whether it’s necessary vs. caregiver convenience
    • Push for non-drug strategies (routines, reduce overstimulation, address pain, sleep/environment management)
    • If used, request lowest effective dose and shortest duration

1. Anticholinergic polypharmacy — combined anticholinergic burden across multiple meds

Core message: Many “small” effects add up when multiple anticholinergic drugs are stacked.

  • Wellness strategy: use a formal medication review and reduce/replace the burden under supervision.
