Brain scans show us that hearing loss may contribute to a faster rate of atrophy in the brain,” Lin says. “Hearing loss also contributes to social isolation. You may not want to be with people as much, and when you are you may not engage in conversation as much. These factors may contribute to dementia.

Loud noise is one of the most common causes of hearing loss. Noise from lawn mowers, snow blowers, or loud music can damage the inner ear and result in permanent hearing loss. Loud noise also contributes to tinnitus.

Studies suggest that older people with hearing loss are more likely to develop Alzheimer's disease and dementia, and hearing loss can be associated with a faster rate of cognitive decline*.

Dementia prevention, intervention, and care: 2024 report of the Lancet standing Commission

High LDL cholesterol is a significant modifiable risk factor not only for cardiovascular disease but also for dementia, as highlighted in the 2024 update by the Lancet Commission. While statins are commonly prescribed to manage cholesterol levels, they are not the only option. There are various lifestyle changes that can also help in lowering LDL cholesterol. Watch the video below where I explain how you can take control of your cholesterol through diet, exercise, and other holistic approaches, empowering you to make informed choices about your health and cognitive well-being. This addition connects the management of cholesterol with the broader implications for brain health, referencing the Lancet Commission's findings to emphasize the importance of addressing this risk factor. Contact me to discuss this risk for dementia and the other 13 modifiable risks factors for dementia.

Ultra-processed foods (UPFs) are associated with an increased risk of cognitive decline due to several factors: High Levels of Additives and Preservatives: UPFs contain artificial additives, preservatives, flavorings, and emulsifiers that can lead to inflammation and oxidative stress in the brain, which are linked to cognitive decline and dementia. High Sugar and Fat Content: These foods are often rich in unhealthy fats and sugars, leading to insulin resistance and obesity, both of which are risk factors for cognitive impairment. Chronic high blood sugar, in particular, can contribute to the development of neurodegenerative conditions like Alzheimer's disease. Low Nutrient Density: UPFs are typically low in essential nutrients, such as vitamins, minerals, and antioxidants that support brain health. A lack of these nutrients can impair cognitive function and accelerate brain aging. Impact on Gut Health: UPFs can negatively affect the gut microbiome, leading to gut inflammation and a leaky gut, which may impact brain health. The gut-brain axis is an important communication pathway, and disruptions can influence cognitive function. Increased Inflammation: The high levels of refined carbohydrates, unhealthy fats, and artificial ingredients in UPFs promote systemic inflammation, a key contributor to cognitive decline and dementia. Displacement of Healthy Foods: A diet high in UPFs often means a reduced intake of whole, nutrient-dense foods like fruits, vegetables, nuts, seeds, and whole grains that are protective against cognitive decline. Reducing UPFs and opting for a diet rich in whole foods can help protect brain health and reduce the risk of cognitive decline. Contact me for some ideas and ways to reduce "addiction" to UPFs.
