Description

One American researcher discovered that older adults (approximately 3000 older adults aged 57-85) with reduced smell (hyposmia) had more than 50% risk of acquiring dementia within five years, regardless of other risk factors. Those who had the worst smell loss (full anosmia) were the ones who would be most likely to acquire dementia within five years. Furthermore, the severity of dementia was linked to the degree of olfactory loss, which means minor smell loss correlates to moderate cognitive impairment compared and a massive smell loss associated with severe Alzheimer's. Have you ever smelled anything that took you right back to a memory? A smell can bring on a wide range of feelings and memories. For older adults, the loss of smell may significantly influence one's quality of life. In Alzheimer’s disease, smell is impacted and for both groups of people, loss of smell often results in a loss of appetite, poor nutrition, and subsequent weight loss. Understand how smell, memory and Alzheimer's disease are intertwined in another valuable of This Is Getting Old: Moving Towards an Age-Friendly World. Tune in to Episode 109: Smell, Memory, and Alzheimer's Disease, and walk-through ways to provide better care for older adults with Alzheimer's. <h1>Key points covered in this episode: </h1> <h2>✔️ How Does Smell Work?</h2> We have smell neurons or receptors in our noses that connect to a very short nerve (about two inches long) called the olfactory nerve. It runs along from the back of our nose to a structure called the amygdala. The amygdala triggers emotions and feelings and is the "emotional spark plug" of the brain. Sinc
