Alzheimer’s Medications: Benefits Versus Risks

Memory loss impairmentThe search for Alzheimer’s medications and a cure is ongoing. How do families decide about the pros and cons of medications for memory loss?

Research (Ellis 2005) exists regarding the benefits of using a class of drugs called cholinesterase inhibitors in the treatment of Alzheimer’s disease and dementia. The American Geriatrics Society cautions against the use of these medications stating that periodic assessments of the benefits and adverse effects should be completed on a regular basis.

Evidence for long-term use is lacking. Cholinesterase inhibitors are not recommended for individuals in the advanced stages of Alzheimer’s disease.

Benefits of Medications to Treat Alzheimer’s Memory Loss

If you are an Alzheimer’s caregiver there are many questions to ask regarding medications:

  • How does one decide whether Alzheimer’s medications offer benefits if research is contradictory?
  • If Alzheimer’s truly is an irreversible condition, what benefit do the medications offer?
  • What are the risks of taking these medications for individuals diagnosed with mild to moderate degrees of memory loss?
  • Should families be more discerning before accepting recommendations to utilize these medications for loved ones diagnosed with Alzheimer’s disease?

The decision to use medications is a personal choice that should be based on family values, the health condition of the individual diagnosed, available finances, and the wishes of the care recipient — if sufficient cognition exists for this information to be expressed.

As with most medical diagnoses there exist an initial diagnosis, a long-term prognosis and plan, and the day-to-day plan and goal of treatment.  With a diagnosis of Alzheimer’s, short and long-term planning are critically important.

Alzheimer’s Medications

One of the initial decisions might be the treatment of the disease with prescription medicines. Common names of medications used to treat Alzheimer’s disease and dementia are Aricept (Donepezil), Memantine (Namenda), Razadyne (Galantamine), Exelon (Rivastigmine), and Aduhelm (Aducanumab) which was recently approved in 2021. 

Other medications to treat behaviors and anxiety associated with memory loss include Celexa (Citalopram), Quetiapine (Seroquel), Haloperidol (Haldol), Olanzapine (Zyprexa), Risperidone (Risperdal), Ziprasidone (Geodon), and others. 

Seeking education about Alzheimer’s medications and treatment options is essential to making the best care decisions for your situation.

The treatment goal of Alzheimer’s medications is maintaining current cognition; thus supporting the idea of preventing further decline or the rate of decline of further memory loss. The American Geriatrics Society states that if a benefit from these medications is not apparent within 12 weeks, the benefit is not likely to occur.

Additionally, evidence is lacking regarding any benefit of treatment for longer than one year. However, what I can say from my personal experience is that discontinuing one or more of these medications can result in significant mental and physical declines. 

There is also recent research that contradicts the path of the development of medications for memory loss. An article called Blots on a Field appeared in Science Magazine that contradicts theories for the prescription drug treatments of Alzheimer’s disease. 

Costs of Managing Alzheimer’s Disease

The costs, both financial and personal, of caring for a loved one with Alzheimer’s disease are high. Estimates by the National Institute on Aging report that the cost of Alzheimer’s disease to the U.S. economy is over $100 billion each year.

Knowing this, it is wise to delay the progression of the disease through the use of medication if this will increase costs to the healthcare system. Conversely, if one is able to delay the progression of the disease through the use of medication, might this delay increasing healthcare costs? 

There is no single, right answer to the question of using medications.

Healthy But Forgetful Versus Forgetful and Sick

Another consideration is the health status of the care recipient. If the individual has no or few other diagnoses than Alzheimer’s there may be benefits to using medications to promote a longer quality of life and the ability to maintain physical and daily activities as long as possible.

This allows families to recognize and enjoy the time remaining and to make the best of the situation before the disease progresses. On the other hand, if many chronic health conditions exist like heart disease, diabetes, COPD, depression, and quality of life is already poor, adding another medication to the mix may offer little long-term benefit.

If one chooses to utilize medications, it is important to monitor for side effects that include stomach disorders resulting in constipation, stomach upset and diarrhea, vomiting, and anorexia. Weight loss is a significant concern for individuals diagnosed with dementia and Alzheimer’s.

Often nutritional supplements like Ensure or Boost are used. In other circumstances, appetite-stimulating medications are prescribed, for example, megestrol or mirtazapine.

Does One Medicine Create the Need for Another?

One might then ask — where is the wisdom in prescribing a medication to treat memory loss that results in weight loss and the need for additional medications and supplements? Indeed, this is why many families choose not to use medications to treat memory loss as the side effects may cause more problems in comparison to the long-term benefits of using the medication.

Under the best circumstances when weight loss occurs, 1:1 attention during mealtimes offers the greatest benefit, even if individuals require hand feeding or handheld foods to make the activity of eating easier.

The choice to use medications should be discussed among family caregivers and the diagnosed individual. It is important to understand the benefits in light of other existing health conditions, the desire of the care recipient, family values, and finances available to pay for long-term care.

In a perfect world, discussing plans for care with the newly diagnosed individual can clear up many of these uncertain decisions for family members. While difficult, these conversations can make Alzheimer’s caregiving less controversial.
