Did you know that research has shown that loneliness plays a role in cognitive decline?

The CDC reported that “social isolation was associated with about a 50% increased risk of dementia.” There are several ways to slow cognitive decline that often comes with the natural aging process. One of the most effective ways to do so is by maintain a healthy social life. This can look different depending on your life and what works best for you.

While it is important to note that loneliness does not directly cause dementia, the effects of a solitary lifestyle can have a negative impact on your cognitive function. Actively socializing throughout your week is key to maintaining healthy brain function. Dementia is a complex condition characterized by a decline in cognitive function, memory loss, and impaired thinking abilities. It is primarily caused by neurodegenerative diseases such as Alzheimer’s disease, vascular dementia, or other underlying neurological conditions. Loneliness can potentially increase a person’s likelihood for cognitive decline in a few different ways.

Loneliness often leads to reduced cognitive stimulation and limited engagement in social activities. Lack of mental engagement and stimulation may contribute to a decline in cognitive abilities over time. Regular social interactions, on the other hand, provide cognitive stimulation and help maintain cognitive function. The feeling on long term loneliness may also have an impact on lifestyle choices that can indirectly impact dementia risk. For example, individuals experiencing loneliness may be more prone to unhealthy habits such as a sedentary lifestyle, poor diet, lack of exercise, and inadequate sleep—all of which have been associated with an increased risk of dementia. These lifestyle impacts can also influence a person’s cardiovascular health. Poor diet, lack of exercise, and sleep can cause hypertension, obesity, and other physical ailments that can negative affect the brain.

A few ways to maintain a healthy social life could include the following:

• Have regular video and phone calls with family and friends.
• Schedule time to eat meals with others either in your home or out at a restaurant.
• Play organized card games (Bridge, Canasta, Rummy) offered at local centers in your area.
• Take a walk with a friend or family member in your neighborhood.
• Join a local tennis or pickleball team.
• Join or create a book club.

It is worth noting that while loneliness may play an important role in a person’s increased chance for dementia, it is not the sole cause. Dementia and other neurological diseases are complex and multifactorial conditions that are influenced by various genetic, environmental, and lifestyle factors.
