The claim “7 medications that cause severe dementia and profound brain damage” is misleading. Most medications do not cause dementia, and it is inaccurate to say that common medicines simply “damage the brain.” However, some medications can affect memory, thinking, alertness, or confusion, especially in older adults, people with kidney or liver problems, or those taking multiple medicines.
Medications that may be associated with confusion or cognitive side effects in some people include:
- Benzodiazepines
- Examples: medicines used for anxiety or insomnia such as diazepam, lorazepam, or alprazolam.
- Long-term use in older adults has been linked with increased risk of falls, confusion, and cognitive problems.
- Strong anticholinergic medications
- These block acetylcholine, a chemical involved in memory and learning.
- Examples include some older allergy medicines, bladder medicines, and certain antidepressants.
- Opioid pain medications
- Can cause drowsiness, slowed thinking, and confusion, particularly at higher doses or when combined with other sedating drugs.
- Some sleep medications
- Certain prescription sleep aids can cause next-day confusion, memory problems, or unusual behaviors in some people.
- Some antipsychotic medications
- May cause sedation and cognitive effects, especially in older adults. They are sometimes used carefully for specific conditions.
- Certain anti-seizure medications
- Some can cause dizziness, slowed thinking, or memory difficulties.
- Some medications with strong sedating effects
- Multiple medicines that cause sedation can add up and increase confusion risk.
Important points
- A medication causing temporary confusion or slowed thinking is not the same as causing permanent dementia.
- Many of these medicines are appropriate and necessary for certain conditions when prescribed and monitored.
- Do not stop any medication suddenly without talking to your healthcare provider.
If an older person develops new confusion, memory changes, or unusual behavior after starting a medication or changing a dose, it is worth discussing with a healthcare professional. Sometimes the cause is a medication side effect, an interaction, dehydration, infection, or another treatable issue.
