20. Over-the-Counter Sleep and Cold Remedies
Many contain hidden antihistamines that can quietly impair memory, especially when used frequently.
Why Older Adults Are at Higher Risk
As we age, the brain becomes more sensitive to medications. Slower metabolism and reduced kidney or liver function mean drugs stay in the body longer, increasing cognitive side effects. Taking multiple medications at once (polypharmacy) further raises the risk.
What You Can Do
Never stop a medication abruptly without medical advice
Review your medication list regularly with a healthcare professional
Ask if lower doses or alternative drugs are available
Watch for signs like confusion, forgetfulness, or personality changes
