Drugs that may cause dementia in the elderly are mainly antipsychotic drugs such as risperidone and olanzapine; antiepileptic drugs such as sodium valproate and phenytoin sodium; and sedative and sleeping drugs such as alprazolam and diazepam. Theoretically all drugs that may impair brain function and affect blood supply to the brain may induce an increased risk of dementia in the elderly. Antipsychotics are the most common medications that may cause an increased risk of dementia in older adults, such as olanzapine, risperidone, and haloperidol. This is because this class of drugs, tends to treat anxiety, depression and schizophrenia by regulating the level of neurotransmitters in the brain. And when these neurotransmitter levels change, it can lead to dementia. Antiepileptic drugs also carry some risk of inducing dementia in older adults, such as sodium valproate, carbamazepine, and phenytoin sodium, to name a few. But epilepsy is much more damaging to brain function and also tends to increase the risk of dementia in older adults if medication is not taken to treat epilepsy. Medications with fewer side effects, such as levetiracetam and lamotrigine, can be used to treat epilepsy. Taking drugs such as alprazolam, diazepam, eszopiclene and other medications that sedate and calm the body, you may still wake up on the morning of the 2nd day feeling tired and dizzy, leading to a decline in cognitive function during the day and inefficiency in work and study. So there is a possibility that this type of medication may increase the risk of dementia in older adults. All medications need to be used under medical supervision.
