Recognizing the early signs of dementia is crucial as it allows families and healthcare professionals to take proactive steps that can delay severe symptoms and improve the overall quality of life for individuals affected.
According to the Alzheimer’s society in the UK, while there is no cure for dementia currently, identifying early signs and symptoms remains essential. With promising results from clinical trials, an early and accurate diagnosis will be key to identifying those eligible for disease-modifying treatments once available. It is also important to note that there are various ways to support individuals living with dementia effectively, even in the absence of drugs aimed at slowing down the progression of the disease.
The New York Times reports that there are five common symptoms experienced during the early stages of dementia that are often overlooked. Memory loss, particularly associated with Alzheimer’s disease, is a well-known symptom, but there are other critical indicators that are equally important for early diagnosis.
While some of these symptoms may be attributed to other causes initially, it is imperative not to ignore them. If these signs persist or if multiple symptoms are experienced simultaneously, seeking a professional health assessment is vital.
1. Changes in personality:
Research led by Angelina Sutin from Florida State University reveals that individuals with dementia may exhibit personality changes before cognitive decline becomes evident. Diminished extroversion, agreeableness, and conscientiousness are common, with these changes intensifying as the disease advances. These shifts can manifest in daily behaviors, such as social withdrawal or reduced social interactions, and are often easier to detect than memory loss.
2. Struggling with driving:
Difficulties while driving can be an early indication of cognitive decline, potentially appearing years before other symptoms, as per Ganesh Babulal, a neurology professor at Washington University in St. Louis. Given that driving involves multiple cognitive functions, any impairment can increase the risk of accidents. While age-related physical issues or medication side effects may contribute, it is crucial to remain vigilant about these changes.
3. Loss of smell:
A diminished sense of smell can be an initial sign of neurodegenerative conditions like Alzheimer’s disease, dementia with Lewy bodies, and Parkinson’s disease. The olfactory system, responsible for our sense of smell, can be compromised years before other symptoms emerge. Unlike hearing or vision loss, which are risk factors for dementia but not direct causes, a loss of smell is an early indicator of these diseases, each affecting smell in unique ways. This could be pivotal for early detection.
4. Sleep problems:
Difficulty sleeping well is another symptom to monitor. Sleep disturbances are common in older individuals, but significant changes like waking up at odd hours or struggling to stay awake during the day could signal dementia. Brain areas regulating sleep, such as the brainstem, are among the first affected in Alzheimer’s, leading to disruptions long before memory problems arise. In conditions like dementia with Lewy bodies and Parkinson’s, a REM sleep behavior disorder may develop, where individuals act out dreams due to brain cell damage controlling paralysis during this phase. These patterns might be early signs of neurodegenerative diseases.
5. Financial difficulties:
While financial troubles can have various causes, when coupled with cognitive or behavioral changes, they might indicate early-stage dementia. While financial issues do not directly cause the disease, sudden or unusual changes like forgetting to pay bills or making impulsive purchases could reflect disruptions in judgement and brain function. Frontotemporal dementia, in particular, can affect judgment early on. Managing finances engages multiple brain areas, making it one of the first domains where cognitive problems become noticeable.
