Dementia impacts millions of older adults in the United States, and its prevalence is expected to rise as the population continues to age. Understanding one’s risk and taking preventive steps is essential for seniors aiming to safeguard their cognitive health. Here, we explore eight diagnostic tests that, when combined, can help identify dementia.

According to the National Institutes of Health (NIH), over six million Americans currently live with dementia, a progressive and debilitating condition responsible for more than 100,000 deaths annually. With the aging population on the rise, the NIH predicts that dementia cases will double by 2060.

Seniors are strongly encouraged to assess their lifetime dementia risk to better focus on prevention strategies. The highest risk is observed in individuals aged 85 and older, with approximately 20% affected. Among seniors aged 55 and older, the risk is 42%, while those aged 75 face a slightly lower but still significant risk of 4%. By understanding these probabilities, older adults can take proactive measures to protect their cognitive well-being.

What Are Risk Factors for Developing Dementia?

Age is among the biggest risk factors for developing dementia. This is because the condition takes years to develop. The gradual damage to the brain occurs over many years, leading to dementia symptoms. Therefore, the longer a person lives, the longer dementia has time to develop.

Familial genes (those passed down from a parent) are also likely to cause dementia. These genes are a cause of 1 in 3 cases of frontotemporal dementia, a common type of dementia. Risk genes, like apolipoprotein, increase a person’s risk of Alzheimer’s disease—but they don’t always cause it.

Chronic health conditions may contribute to a senior’s risk of developing dementia. Diabetes, vision loss, hearing loss, and head injuries affect brain health. High blood pressure, high cholesterol, and depression should also be managed to mitigate damage to the brain.

Lifestyle choices are known to impact brain health. Dementia is more likely in seniors who fail to engage in healthy behaviors. Smoking, drinking excessively, and a lack of physical activity are linked with an increased risk of developing dementia. Social isolation, too, contributes to the risk.

What Tests Help Diagnose Dementia?

Older adults who are aware of their high-risk factors for dementia should be tested for the condition. However, it’s important to note that no single test diagnoses dementia. Multiple tests are needed for a healthcare provider to notice patterns in the loss of skills and functions.

1. Mini Mental State Examination

Consisting of a brief, structured test of cognitive functions, the Mini Mental State Examination (MMSE) is a common way to assess cognitive function. However, the test comes with limitations, such as being unable to differentiate between dementia and failing to capture the early stages of dementia.

2. Montreal Cognitive Assessment

Additional tests are needed, such as the Montreal Cognitive Assessment (MoCA). This test is helpful for assessing individuals showing mild signs of cognitive decline or early Alzheimer’s disease. As a more sensitive test, the MoCA detects mild cognitive impairment better than the MMSE.

3. Addenbrook’s Cognitive Examination

The Addenbrook’s Cognitive Examination (ACE) is a thorough assessment that helps differentiate between different types of dementia. Being a comprehensive exam, it provides an overall picture of an older adult’s cognitive health by evaluating memory, attention, language, and visuospatial abilities.

4. Functional Assessment Staging Test

Seniors who are diagnosed with Alzheimer’s disease may take the Functional Assessment Staging Test (FAST) to help medical providers and caregivers plan for future care. The test involves assessing the elderly person’s ability to perform daily activities rather than measuring cognitive health.

5. Clock Drawing Test

This simple test requires the senior to draw a clock with numbers and hands directed at a specific time, such as 10 minutes after 12 o’clock. A normal result shows the numbers and hands correctly. Potential cognitive impairment may be diagnosed when the numbers are placed incorrectly.

6. Brain Scans

Positron Emission Tomography (PET) scans show patterns of brain activity and are helpful in the diagnosis of dementia. As a medical imaging technique, it provides a 3D image of organs, like the brain. The presence of a buildup of tau protein, a hallmark of Alzheimer’s disease, is revealed.

7. Global Deterioration Scale

Testing memory, language, and the ability to perform daily tasks, the Global Deterioration Scale (GDS) helps healthcare professionals understand the progression of dementia to guide future care. The scale divides dementia into seven stages, each of which represents different levels of cognitive decline.

8. Neuropsychological Tests

Neuropsychological testing is useful for confirming or ruling out dementia, especially when other medical conditions are suspected. The test differentiates between different types of dementia and is used to monitor the progression of dementia and guide the course of treatment.

Diagnosing dementia requires a combination of cognitive assessments, a medical history, as well as physical and mental status exams. It’s also helpful to observe any changes to the senior’s thinking and day-to-day functioning. When dementia is suspected, a visit to a healthcare provider can help.

Dementia Care from Assisting Hands

The professional caregivers at Assisting Hands Home Care offer reliable transportation and can accompany seniors to doctor appointments for neurological evaluations. If a dementia diagnosis is made, we provide compassionate dementia care services in the comfort of the senior’s home.

Care responsibilities include preparing healthy meals and serving beverages throughout the day to keep seniors hydrated. We respectfully assist with hygiene tasks, such as bathing, toileting, grooming, and dressing. Light housekeeping is performed to ensure a clean and comfortable living space.

Dementia care involves mental stimulation, which caregivers provide by playing games, initiating conversations, and taking care recipients on outings. Our experienced dementia caregivers help reduce agitation with distraction techniques, prevent wandering, and continually monitor the elderly individual to promote safety and ensure their care needs are met.

If your aging loved one is diagnosed with dementia after testing, it’s crucial to begin planning for the future.
