A study of 733 women in their 80s found that significant changes in sleep patterns, including excessive napping, may serve as early indicators of dementia, highlighting the importance of monitoring sleep habits for early detection.
A British doctor has highlighted difficulty swallowing as a potential early indicator of dementia, citing a 2008 study and explaining that it can result from damage to brain regions controlling the swallowing reflex. This symptom, known as dysphagia, can lead to muscle weakness, coordination problems, and reduced throat sensation in those with dementia, causing weight loss, dehydration, and malnutrition. With Alzheimer's disease being a primary cause of dementia, the warning signs of dysphagia should not be ignored, as they can lead to serious health risks.
