Medications
Another common cause of dementia that can be easily avoided is over-medication. Many prescription drugs, as well as excessive use of over-the-counter drugs, may cause patients to be in a state of imitation of dementia. Among the culprits are anticholinergic medications that are antihistamines like Bendadryl or some sleep aids like Unisom.
It can also be attributed to antidepressants. Note that lack of quality sleep can also lead to the risk of dementia. When you depend on OTC drugs for sleep, you can add even more insult. Focus on hygiene and quality sleep, and you will lower the risk of dementia as well as other body conditions.
