Current Alzheimer's medications can help for a time with memory symptoms and other cognitive changes. Two types of drugs are currently used to treat cognitive symptoms:
Cholinesterase inhibitors. These drugs work by boosting levels of a cell-to-cell communication chemical depleted in the brain by Alzheimer's disease. Most people can expect to keep their current symptoms at bay for a time.
Less than half of those taking these drugs can expect to have any improvement. Commonly prescribed cholinesterase inhibitors include donepezil (Aricept), galantamine (Razadyne) and rivastigmine (Exelon). The main side effects of these drugs include diarrhea, nausea and sleep disturbances.
- Memantine (Namenda). This drug works in another brain cell communication network and slows the progression of symptoms with moderate to severe Alzheimer's disease. It's sometimes used in combination with a cholinesterase inhibitor.
Creating a safe and supportive environment
Adapting the living situation to the needs of a person with Alzheimer's is an important part of any treatment plan. For someone with Alzheimer's, establishing and strengthening routine habits and minimizing memory-demanding tasks can make life much easier.
You can take these steps to support a person's sense of well-being and continued ability to function:
- Always keep keys, wallets, mobile phones and other valuables in the same place at home, so they don't become lost.
- See if your doctor can simplify your medication regimen to once-daily dosing, and arrange for your finances to be on automatic payment and automatic deposit.
- Develop the habit of carrying a mobile phone with location capability so that you can call in case you are lost or confused and people can track your location via the phone. Also, program important phone numbers into your phone, so you don't have to try to recall them.
- Make sure regular appointments are on the same day at the same time as much as possible.
- Use a calendar or white board in the home to track daily schedules. Build the habit of checking off completed items so that you can be sure they were completed.
- Remove excess furniture, clutter and throw rugs.
- Install sturdy handrails on stairways and in bathrooms.
- Ensure that shoes and slippers are comfortable and provide good traction.
- Reduce the number of mirrors. People with Alzheimer's may find images in mirrors confusing or frightening.
Regular exercise is an important part of everybody's wellness plan — and those with Alzheimer's are no exception. Activities such as a daily 30-minute walk can help improve mood and maintain the health of your joints, muscles and heart.
Exercise can also promote restful sleep and prevent constipation. Make sure that the person with Alzheimer's carries identification if she or he walks unaccompanied.
People with Alzheimer's who develop trouble walking may still be able to use a stationary bike or participate in chair exercises. You may be able to find exercise programs geared to older adults on TV or on DVDs.
People with Alzheimer's may forget to eat, lose interest in preparing meals or not eat a healthy combination of foods. They may also forget to drink enough, leading to dehydration and constipation.
- High-calorie, healthy shakes and smoothies. You can supplement milkshakes with protein powders (available at grocery stores, drugstores and discount retailers) or use your blender to make smoothies featuring your favorite ingredients.
- Water, juice and other healthy beverages. Try to ensure that a person with Alzheimer's drinks at least several full glasses of liquids every day. Avoid beverages with caffeine, which can increase restlessness, interfere with sleep and trigger frequent need to urinate.
Certain nutritional supplements are marketed as "medical foods" specifically to treat Alzheimer's disease. The Food and Drug Administration (FDA) does not approve products marketed as medical foods. Despite marketing claims, there's no definitive data showing that any of these supplements is beneficial or safe.
