Introduction
What was I going to blog on today? Oh Yeah. . . brain fog, memory loss & cognitive decline!
-Yes, that WAS intentional. As if you didn’t know 😉

We all want to actively GROW our brain power, not just preserve it. And this series of articles will address that as well as the unfortunate other side: brain fog, cognitive decline and memory loss that may be the first signs of developing dementia.
To ensure we’re using the same terminology: Dementia is a generalized term for loss of cognitive functions: thinking, remembering, and reasoning. Alzheimer’s disease is the most common, most well-known, and most feared type of dementia.
The brain shrinkage that precedes a dementia diagnosis can begin many years earlier. This is one reason why prevention and early diagnosis are key. We’ll discuss both.
While there’s no cure for dementia, numerous studies suggest that early intervention and lifestyle changes can significantly reduce the risk of developing cognitive decline. In this blog series, we’ll explore various strategies to maintain brain health, starting with an overview of prevention techniques.
Neuroplasticity
“Neuroplasticity” is the brain’s remarkable ability to reorganize itself by forming new neural connections throughout life. This adaptability is crucial for learning, memory, and recovery from brain injuries. Originally recognized in the adult brain in the 1960s, it wasn’t commonly understood by the general public until the 1990s.
As we age, promoting neuroplasticity becomes vital in preserving cognitive function and preventing mental decline.
Various studies highlight how activities that challenge the brain, like learning a new skill or engaging in complex tasks, can enhance neuroplasticity and cognitive resilience. These activities become more and more vital to our well-being as we age.
Brain-Derived Neurotrophic Factor (BDNF) and the Role of Exercise
Brain-Derived Neurotrophic Factor (BDNF) is a protein crucial for brain health. It supports the survival and growth of neurons and is essential for learning, memory, and cognitive resilience. High levels of BDNF are associated with improved cognitive function and protection against neurodegenerative diseases.
Exercise is one of the most effective ways to increase BDNF levels in the brain. Both aerobic exercises, like running or swimming, and resistance training can boost BDNF, supporting brain health and enhancing neuroplasticity. A meta-analysis published in Neuroscience documents numerous articles showing regular exercise led to significant increases in BDNF levels. The increase improves cognitive performance and protects against age-related decline.
Incorporating regular exercise into your routine is a powerful way to support overall brain health. The best evidence says we should all aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week. Add strength training exercises twice a week for the best results.
Good Nutrition
What we eat significantly impacts our brain health. A balanced diet rich in antioxidants, healthy fats, vitamins, and minerals provides the brain with the necessary resources to function optimally. Foods like leafy greens, berries, nuts, soy, and fatty fish support cognitive health.
Research published in Proceedings of the Nutrition Society emphasizes the link between nutrition and brain function, highlighting the importance of a diet that supports brain health throughout life.
Appropriate Amounts of Sleep
Sleep plays a critical role in memory consolidation and brain detoxification. During sleep, the brain processes information from the day and clears out harmful waste products. Lack of sleep can impair cognitive function and increase the risk of neurodegenerative diseases.
The Journal of Clinical Sleep Medicine outlines how sleep quality and duration are crucial for maintaining cognitive performance and preventing decline.
Brain Exercises
Just like our bodies, our brains need regular exercise to stay fit. Engaging in mentally stimulating activities, such as puzzles, reading, or learning a new language, can strengthen cognitive abilities and promote neuroplasticity.
Studies suggest that consistent brain exercises can enhance cognitive reserve and delay the onset of dementia-related symptoms.
Preventing cognitive decline and memory loss is a multifaceted approach that involves nurturing the brain through neuroplasticity, proper nutrition, adequate sleep, regular mental challenges, and physical exercise. By incorporating these habits into our daily lives, we can empower ourselves to maintain cognitive health and reduce the risk of dementia.
I’ll go deeper into each of these aspects and how they can affect your future in the upcoming series.
