Certain medications, especially when used long-term or in high doses, have been linked to cognitive decline and symptoms that mimic or accelerate dementia. Common culprits include anticholinergic drugs (often found in allergy, depression, and bladder medications), some sleep aids, and certain painkillers. These medications can interfere with brain chemicals essential for memory and thinking. If you or a loved one are experiencing sudden confusion, memory loss, or changes in thinking, it’s important to review all medications with a healthcare professional. Early awareness and action can make a significant difference.
