Antidementia Drugs May Delay or Prevent Nursing Home Placement: Study

Researchers note that remaining self-sufficient enough to stay in a community setting can lead to better health outcomes and less financial burden on families.

A new review of multiple studies indicates that anti-dementia drugs may delay symptom progression, allowing some older patients to live independently longer before requiring nursing home care.

The findings were published in the journal European Geriatric Medicine on January 13, examining several types of anti-dementia drugs that may help reduce Alzheimer’s symptoms, a leading cause of long-term care placement among older adults.

Anti-dementia drugs include cholinesterase inhibitors (CEIs), like Aricept, Exelon and Razadyne, NMDA receptor antagonists like Namenda, or combinations of both.

Cholinesterase inhibitors work by slowing the breakdown of acetylcholine, a chemical in the brain that plays an important role in memory and learning. By preserving higher levels of this neurotransmitter, the drugs help support communication between brain cells.

NMDA receptor antagonists act on a different brain pathway by limiting excessive activity of glutamate, a chemical that can disrupt normal brain signaling when present at high levels. This helps stabilize communication between nerve cells.

Although these medications have been shown to improve memory, thinking and overall cognitive function in some patients, they have also been associated with side effects such as nausea, diarrhea, insomnia and dizziness.

For the study, researchers from Thailand conducted a review of 12 prior studies that included nearly 1,400 patients. Led by Dr. Pitchayut Rattanatanyapat, the team analyzed the use of anti-dementia drugs among individuals with Alzheimer’s disease and mixed dementia.

According to the data, anti-dementia drugs managed to delay nursing home admissions among study participants, with a 57% reduction in Alzheimer’s disease nursing home admissions and a 16% reduction in nursing home placement for those given the same medications who suffered mixed-type dementia symptoms.

Rattanatanyapat noted that all anti-dementia drugs were found to help delay admission to a nursing home for individuals with Alzheimer’s disease. None stood out as being better at doing so than any other, with data indicating they all worked similarly to reduce that risk.

Researchers speculate that the treatments may help delay nursing home placement because they offer early intervention, reducing the severity of symptoms and keeping patients in community-based settings longer.

The team noted that delaying nursing home admission can help reduce financial burdens on the healthcare system and families, as well as improving patient care early on. However, they also called for more studies to determine if there is a true link between anti-dementia drugs and delayed admission to nursing homes, as well as understanding that mechanism better.

Health experts warn that as the worldwide population continues to age, there could be an increase in Alzheimer’s and dementia diagnoses, which already affect millions of people globally.
