Affecting millions of people all over the world, dementia is the current seventh leading cause of death globally. The World Health Organization states that 57 million people had dementia in 2021, the most common form of it being Alzheimer which contributes to 60-70% of cases. One of the most devastating things about this disease is that there is no cure for it. Researchers have been studying the disease in various contexts, but there are still many aspects of this mental condition that we are not aware of. While there is no cure for the disease, getting treatment for dementia helps you minimize the symptoms and sustain your quality of life. The best way to deal with dementia is catching it early. That will allow healthcare professionals to give you the best possible treatment. Important Symptoms That Go Unnoticed When people think of dementia, memory problems are usually the first thing that comes to mind. However, there are many subtle signs of the disease that we might miss. A dementia diagnosis comes with the understanding that the disease can change a person’s entire being, the way they think, how they behave, even their core values that make up the person’s identity. Understanding and addressing these sensory issues earlier could make a huge difference. It could help healthcare providers offer the crucial emotional and social support that patients need during what can be a very confusing and upsetting time. Plus, recognizing changes in a person's senses can also help doctors determine a dementia diagnosis. These signs are unrelated to simple memory loss. How Dementia Changes How We See and Hear Dementia often affects how a person experiences the world, changing how they understand what they see and hear. The Alzheimer’s Society explains that this happens because dementia damages the brain, leading to things like seeing shadows as objects or mistaking family members. These changes can be very confusing and upsetting for the person and their loved ones, making supportive responses crucial to maintain their confidence. A sudden, quick change could be serious, so call a doctor right away. Difficulties with Hearing and Understanding Sounds, Especially in Noisy Places Losing hearing in middle age (40-65) can increase your risk of dementia, and sometimes, hearing problems are an early sign. According to the Alzheimer’s Society as we age, hearing often declines, making it harder to hear clearly, especially in busy places. There are two types: one where ears don't pick up sounds well, and another where the brain struggles to process sounds. Getting your hearing checked and using hearing aids can help reduce dementia risk and improve memory and thinking skills. Protecting your hearing early in life is also important. A Reduced Sense of Smell and Taste Our sense of smell, often underestimated, provides vital information and can be an early indicator of dementia. According to the University of Chicago, research shows a rapid decline in smell can predict changes in brain regions linked to Alzheimer's disease, even before memory problems appear. This discovery could lead to simple smell tests for earlier detection of cognitive decline. While more research is needed, this inexpensive tool offers hope for identifying those at higher risk sooner, potentially leading to better treatments. Problems with How We Feel Touch According to a 2023 study published in the eBioMedicine, while hearing and vision are often studied, research now shows that changes in our sense of touch can also be linked to cognitive decline. Studies have found that people with mild cognitive impairment often have reduced sensitivity to touch compared to others. This means they might not feel things as clearly. This connection between touch sensitivity and memory suggests that looking at all our senses, not just sight and hearing, is important for understanding how the brain changes as we age and its role in conditions like dementia.
