How Loneliness Increases The Risk Of Age-Related Memory Loss:

 Different research conducted found that different levels of loneliness were associated with cognitive decline and the risk of age-related memory loss.

How Loneliness Increases The Risk Of Age-Related Memory Loss:

It is well established that people of all ages will see some degree of memory or cognitive change as they age. This can be minor problems like occasionally forgetting people’s names or where one kept the car keys or major problems such as dementia.

 Although it is expected that old persons will experience a memory decline, it was found out that loneliness or social isolation enhances the likelihood of developing faster or more severe memory issues.

Loneliness and Memory: A Connection Found

Research work conducted to establish the link between different factors and Alzheimer's disease has revealed that loneliness causes memory loss or dementia in elderly people. In one of the large-scale studies conducted in 2020, the authors observed more than 2000 older individuals for a year, evaluating them for 12 years. 

In the study, they learned that people who often said they felt lonely got worse, in terms of their memory and thinking, compared to those who did not feel lonely. Extremely lonely people were 2. 36 times more likely to develop Alzheimer’s disease and had a 1. 64-fold faster cognitive decline rate. 

Similarly, other researchers have also drawn similar conclusions. A link between loneliness and lower episodic memory, working memory, and spatial memory has been determined among elderly subjects. 

According to one research, social isolation and loneliness were related to an increased deterioration in thinking abilities equivalent to that of two years of aging. MRI scans also reveal that loneliness also leads to faster degradation of the regions in the brain associated with memory, such as the hippocampus.

In this article, it will be highlighted how loneliness affects the brain.

It is now clearer to scientists why loneliness can be so toxic to the elderly and elderly-like people whose brains require a considerable amount of constant stimulation. Social isolation or loneliness is a stress that continuously stresses the body. This results in the arousal of the “fight or flight” response which triggers some inflammation and stress hormones such as cortisol.

Short-term stress is highly adaptive and allows individuals to meet specific goals; however, the long-term engagement of stress pathways gradually wears down the body and brain. The inflammation continues and causes harm to the brain cells and the neurons that are present in the brain. This makes the brain prone to developing plaque, poor blood circulation, and even the loss of size in the important regions responsible for memory.

Loneliness also results in reduced stimulation leading to demotivation, factors that are important in enhancing cognitive reserve. Through interaction as well as keeping the mind engaged in social activities, the brain is subjected to rigorous tasks, which are required to maintain the health of the brain. In the long run, this causes more and more deterioration of the brain's ability to hold and process information.  

Keeping Agitation Minimal To Guard Recall

Fortunately, loneliness is a modifiable condition, and there is always an opportunity to initiate social interventions. Most people experience some loss of memory as they age, however, there are several practical ways of preventing it and preserving a healthy brain and a strong body to the senior years.

Some of the ways old individuals can prevent loneliness include; enrolling in social groups or activities, having set visits with friends and families, pet adoption, volunteering, and ensuring social interaction is a routine. Therefore, keeping connections with friends, coworkers, and other loved ones counteracts inflammation while keeping our brains in a healthier state for as long as possible.

As people live longer, worrisome age-dependent diseases such as Alzheimer’s and other dementias become major concerns. Knowing about factors such as loneliness provides an avenue in which the elderly, families, and communities can intervene to prevent or at least reduce the likelihood of senior loved ones developing poor brain health. 

Allowing steps to be taken to improve social interaction might be the factor that significantly improves one’s ability to remember events, regain independence, and/or generally improve their quality of life.
