6. Opioid Pain Medications
Opioids are used to manage certain types of moderate to severe pain. Examples include morphine, oxycodone, and hydrocodone.
These medications can cause drowsiness and impair attention. In some people, particularly older adults or those who are acutely ill, they may also contribute to confusion or delirium.
The risks can increase when opioids are combined with alcohol, benzodiazepines, or other sedating substances.
It is important to distinguish these short-term cognitive effects from dementia. Opioid-related confusion does not automatically mean that permanent brain damage has occurred.
What to do: Take opioids only as prescribed, avoid unapproved combinations with sedating substances, and report new confusion to a healthcare professional. Severe sleepiness or slow, difficult breathing may indicate an overdose and requires emergency assistance.
7. Certain Antipsychotic Medications
Antipsychotic medications are prescribed for specific psychiatric conditions and, in selected circumstances, severe behavioral symptoms associated with dementia.
Examples include risperidone, olanzapine, and quetiapine.
Depending on the medication and dose, side effects may include sleepiness, dizziness, movement problems, and changes in alertness. These effects can be particularly important in older adults.
For people with dementia, antipsychotic medications carry additional risks, including an increased risk of stroke and death in certain circumstances. They should be used cautiously and only when the potential benefits justify the risks.
What to do: Discuss new or worsening confusion, excessive sedation, or movement changes with the prescribing clinician. These medicines should not be stopped or adjusted without medical guidance.
8. Certain Muscle Relaxants
Muscle relaxants are used for some painful muscle spasms and related conditions. Examples include cyclobenzaprine and carisoprodol.
Some medicines in this category can cause:
- Drowsiness.
- Dizziness.
- Slower reaction times.
- Confusion, particularly in susceptible older adults.
The risk may be greater when these medications are combined with opioids, sleep medicines, or other substances that depress the central nervous system.
These effects are not proof that a person is developing dementia. However, persistent cognitive symptoms deserve medical evaluation.
What to do: Ask your healthcare professional whether the medicine is still needed and whether other treatment options may be appropriate. Avoid driving if you feel drowsy or impaired.
Does Taking These Medications Mean You Will Develop Dementia?
No. This is an important distinction.
