Alzheimer's Self-Test: How to Check for Early Signs at Home

If you or a loved one is concerned about the possibility of Alzheimer's disease or dementia, there are several effective self-assessment techniques that can help identify early warning signs. These methods often involve simple cognitive evaluations, which can be carried out at home using standardized tools and questionnaires. While these tests are not a substitute for professional diagnosis, they can provide valuable insight into cognitive health.

1. Assessing Cognitive Function Through Basic Math

One of the most commonly used techniques involves testing basic arithmetic skills. A standard question used in clinical assessments is asking the individual to subtract 7 from 100, and then continue subtracting 7 from the result multiple times. This task assesses attention, calculation ability, and working memory. In the early stages of dementia, individuals may struggle with the sequence or take longer than usual to respond. Family members can assist by observing the speed and accuracy of the answers, which can help determine if there are any underlying cognitive impairments.

2. The Clock Drawing Test: A Simple Visual Evaluation

The clock drawing test is another widely recognized method used in dementia screening. The task involves asking the person to draw a clock showing a specific time—typically 11:10. This time is chosen because it requires understanding of both hour and minute hand placement. Individuals with normal cognitive function can usually complete the task without difficulty. However, those in the early stages of Alzheimer's may struggle with spatial awareness, planning, or execution, resulting in an inaccurate or incomplete drawing.

Why These Tests Matter

These assessments are valuable because they can detect subtle changes in memory, reasoning, and motor skills. They are often used in combination with other evaluation tools to form a more complete picture of cognitive health. If the results indicate potential issues, it's important to consult a healthcare professional for a more thorough assessment and possible diagnosis.

What to Do After Self-Testing

If you or a family member notices consistent difficulties during these tests, it's advisable to seek medical advice. Early detection of Alzheimer's can lead to better management of symptoms and access to treatments that may slow disease progression. Additionally, lifestyle changes such as mental exercises, a healthy diet, and regular physical activity can support brain health and potentially delay the onset of more severe symptoms.
