Men and women with early Alzheimer’s disease may learn new skills from mental training exercises, a new study reports. The benefits may help them to recall important information and better go about their daily tasks, improvements that may ease the burden somewhat for caregivers, at least in the short-term.
“By combining specific cognitive rehabilitation strategies, we can help people with Alzheimer’s disease remain engaged in daily activities,” says study author David A. Lowenstein, Ph.D., of the University of Miami School of Medicine in Florida. These improvements, he adds, may allow people with Alzheimer’s to retain a connection to their family and friends and the world as a whole for a longer period of time.”
The research, published in the July/August issue of the American Journal of Geriatric Psychiatry, involved 44 men and women suffering from early Alzheimer’s. All were taking drugs such as Aricept that may provide limited benefits for some early in the course of the disease.
Twenty-five of the study participants were given training, “cognitive rehabilitation,” consisting of two weekly 45-minute sessions for 12 weeks. During the training sessions, they were taught strategies for remembering names, such as connecting facial features with somebody’s name. A man named Sam who smiled a lot, for example, might be remembered as “smiling Sam.” They were also encouraged to keep memory journals where they could record such items as doctors’ appointments, the names and phone numbers of family members, and the time they took their medications, and to review their notebooks twice each day. Additional training taught ways to count change after making a purchase, how to use a calculator to balance a checkbook, and how to manipulate physical objects such as keys. Those with Alzheimer’s and their caregivers were encouraged to practice all these techniques at home.
The remaining study participants received “mental stimulation” exercises, such as crossword puzzles and word games to do at home. They also played computer games and simulations that encouraged them to respond to visual challenges and were encouraged to speak about subjects such as where they grew up.
On average, those who practiced the “cognitive rehabilitation” exercises showed a 170 percent improvement in their ability to recall names and faces compared with those who received the mental stimulation exercises. They also had a 71 percent improvement in their ability to provide proper change after a purchase. In addition, they responded better to their surroundings, were better oriented in terms of time and place, and could process information more rapidly. However, neither group showed any improvements in their ability to balance a checkbook or manipulate objects such as keys.
The findings dovetail on another recent study from the University of Washington in St. Louis that also suggested people with Alzheimer’s retain certain crucial memory functions. That report found that men and women suffering from early Alzheimer’s still had the ability to perform long-ingrained and deep-seated cognitive skills such as driving a car, speaking a language, or typing on a keyboard. [See the article, “Alzheimer’s May Preserve Certain Memory Skills.”]
“Taken together, these studies introduce the exciting notion that older people who are in the early stages of Alzheimer’s disease can be taught techniques to help stay engaged in everyday life,” says Neil Buckholtz, Ph.D., head of the Dementias of Aging Branch at the National Institute of Aging, the agency that sponsored the research. “These findings show it is possible to pinpoint what memory capabilities are preserved in early Alzheimer’s disease and suggest ways to target those memory functions and make the most of them.”
These results are promising and may offer improved strategies for caring for those with dementia. However, not all persons with Alzheimer’s, even those in the early stage of the disease, may be able to engage in a mental exercise routine. If you try such exercises and the person with Alzheimer’s does not respond favorably, you should continue to be encouraging and not make him or her feel as if they have failed. Regardless of the apparent response, the activity and human contact are often beneficial for the person with Alzheimer’s.
