A List of Common Dementia Medications

Dementia is a general term for the loss of memory caused by physical changes in the brain. Alzheimer’s is the most common type of dementia. Unfortunately, there are currently no medications that can reverse or halt disease progression for most of the dementias. There are five Alzheimer’s disease (AD) medications approved by the FDA that have been shown to provide some symptom relief. However, they can’t improve the underlying brain damage or even always clearly decrease the speed of cognitive decline.

The FDA has approved a group of medications for mild to moderate AD known collectively as cholinesterase inhibitors. These may delay or prevent Alzheimer’s symptoms from worsening, and they may help manage some of the behavioral symptoms that accompany a diagnosis of AD. These medications include donepezil (Aricept), galantamine (Razadyne), and rivastigmine (Exelon). The first cholinesterase inhibitor FDA approved for AD was known as tacrine (Cognex). It’s been removed from the market due to safety concerns. 

For moderate to severe AD, the FDA has approved and additional medication that is not a cholinesterase inhibitor.  This medication is known as memantine (Namenda). Its primary use is to potential delay the decline in cognitive and behavioral symptoms in people with moderate to severe AD. This permits certain patients to retain some routine functionality longer than they would have without the medication. Donepezil has also been approved for use in more advanced AD.

The effectiveness of these medications is highly variable. Whatever effectiveness they do have tends to diminish over time. According to the Alzheimer’s Association there is also research suggesting that some of the AD medications may provide some benefit for vascular dementias and Parkinson's dementia. While these medications are intended to stop the progression of Alzheimer’s disease, additional medications may be required to alleviate the many challenging symptoms. These include:

  • antidepressants
  • anti-anxiety medication
  • sleep aids
  • antipsychotics

Here are some of the commonly prescribed medications and their uses.
