Brain Training Prevents Mental Fragility And Falling

Some seniors can experience the mental difficulties of old age, like forgetfulness or poor attention span. Yet others somehow manage to remain mentally sharp, even well into their 80s. Some call these people “superagers”; those whose memory and attention is well above average for their age, on par with healthy, active 20 and 30-year-olds. 

Facilitating mental exercises allows for more fulfilling activities and life enrichment and can reduce falls and harmful situations, ultimately lowering rehospitalizations.

• As a person gets older, changes occur in all parts of the body, including the brain. Certain parts of the brain shrink (such as the prefrontal cortex and hippocampus); both areas are important to learning, memory, planning, and other complex mental activities. 
• In some people, structures called plaques and tangles develop outside of and inside nerve cells of the brain, which in large amounts, can result in dementia (such as Alzheimer’s disease). 
• Lastly, as people get older, research shows that they tend to avoid unpleasant situations, such as any discomfort or frustration associated with mental exertion. If people consistently sidestep the discomfort of mental effort, it can be detrimental to the brain. All brain tissue wastes away from disuse. If you don’t use it, you lose it.

Falls Among the Aging Are All Too Common

In both inpatient and long term care settings, falls happen at staggering rates:

• Studies have found that falls occur in hospitals at the rate of 3-5 per 1000 bed/days
• AHRQ estimates that 700,000 to 1 million hospital patients fall per year
• Up to half of the 1.6 million long term care residents experience a fall each year 

In a value-based care environment, avoiding falls can lead to higher quality outcomes and cost savings. But what causes them to occur at such significant levels?

Can Brain Activity Lead to Falling?

Aside from memory problems, changes in brain activity can influences one’s chances of falling: 

The ability to keep balance and avoid falling depends not only on leg strength, but also on complex and simple reaction times, known as ‘brain speed’. The faster one’s brain can move between events (identifying a loss of balance and executing a safe alternative to maintain balance), the better off people are in avoiding falls. In other words, when some people fall, their brains may not be keeping up with what is happening and unable to quickly recover from a loss of balance.

People whose brains work hard when trying to complete complex activities (such as walking and talking at the same time) may have a higher risk of falling than those individuals who do both tasks with ease. When elders perform any cognitively demanding task, their brains become more active to handle the challenge. Walking and talking at the same time requires greater attention. Thus, more brain effort is expended, which in some individuals can lead to falling. 

Alzheimer’s disease (AD) is a disease associated with a loss of memory and intellectual abilities. The risk of developing AD increases with advancing age and gradually gets worse over time. One of the most common safety problems in persons with AD is that of falling. It’s estimated that up to 60% of persons with AD experience one or more falls annually because of poor mobility, which includes the ability to walk safely and maintain good balance. Persons with AD tend to exhibit marked impairments with both. This places them at increased fall risk.  

• Just like physical exercise, mental exercise is good for for seniors. Mentally stimulating activities help preserve brain function. Keeping your mind engaged increases the brain’s vitality and helps build its reserves of brain cells and connections. 
  
• Promote stimulating activities that they enjoy; reading, writing, puzzles, crosswords, etc. Any mentally challenging activity will keep a mind sharp.
  
• Critical brain regions are stimulated by engaging in physical and mental tasks requiring effort. In other words, vigorous exercise and strenuous or challenging mental effort (such as swimming daily if possible or learning a foreign language or taking an online college course), helps keep the brain youthful and sharp.
