Some medications can temporarily impair memory, attention, or alertness. In certain circumstances, medication-related confusion can improve after a clinician adjusts treatment or addresses the underlying problem.
Research has also found associations between prolonged exposure to some medications, particularly those with strong anticholinergic effects, and a higher risk of dementia. Nevertheless, researchers have not established that these medicines directly cause dementia in every person who uses them.
Age, underlying illnesses, sleep problems, depression, and the conditions being treated can also influence memory and thinking.
Never stop a necessary medication because of a frightening headline. The safest approach is to review the potential benefits and risks with a qualified healthcare professional.
Warning Signs That Deserve Medical Attention
Contact a healthcare professional if you or a family member develops:
- Persistent or worsening memory problems.
- New confusion after starting a medication.
- Unusual daytime sleepiness.
- Repeated falls or loss of balance.
- Difficulty managing everyday activities.
- Noticeable changes in attention or behavior.
Sudden confusion is different from gradual forgetfulness. It can be caused by infections, medication effects, dehydration, or other urgent medical problems.
Seek urgent medical care if confusion develops suddenly, particularly when accompanied by fever, weakness, difficulty speaking, severe headache, or a change in consciousness.
Five Ways to Use Medication More Safely
1. Keep an updated medication list. Include prescription medicines, over-the-counter products, vitamins, and supplements.
2. Ask for regular medication reviews. This is especially important for older adults who take several medications.
3. Check for overlapping ingredients. Some cold, allergy, and nighttime products contain the same active ingredients or have similar sedating effects.
4. Report changes in memory or alertness. Record when symptoms began and whether they followed a new prescription or dose change.
5. Never change treatment on your own. Some medications require gradual dose reductions, and stopping certain drugs abruptly can be dangerous.
