Understanding Memory Lapses and Alzheimer’s
As awareness around brain health continues to grow, more people are becoming concerned about memory lapses and their potential link to Alzheimer’s disease. However, experts emphasize the importance of not jumping to conclusions or undergoing unnecessary tests too quickly. Not every instance of forgetfulness indicates a serious neurological condition, and excessive testing can lead to anxiety, misdiagnosis, and avoidable medical costs.
Dr. Asma Bibi, Consultant Hematopathologist, Consultant NCGM Chief of Laboratory, Chennai and Kerala, Neuberg Diagnostics Pvt Ltd, explained that different individuals have various reasons for experiencing memory problems. “An occasional forgetfulness, especially in a younger person, is usually related to lifestyle and psychological factors such as stress, burnout, sleep deprivation, anxiety, or nutrition. These factors can temporarily affect perception and attention, but they are generally not signs of neurodegenerative illness,” she said.
Not All Memory Issues Mean Alzheimer’s
Occasional forgetfulness is quite common, particularly among younger individuals. Factors such as stress, burnout, poor sleep, anxiety, and nutritional deficiencies can temporarily impact memory, focus, and attention. Examples include forgetting where you placed your keys, walking into a room and forgetting why, or missing minor details during busy or stressful days.
These issues are typically linked to lifestyle or psychological factors rather than neurodegenerative diseases. In such cases, experts advise against undergoing Alzheimer’s biomarker testing.
When Should You Consider Alzheimer’s Testing?
Testing becomes relevant only in specific clinical situations where symptoms suggest a deeper neurological issue. Doctors recommend evaluation if:
- You are above 65 years of age
- Memory problems are progressively worsening over time
- There is a strong family history of early-onset dementia
- Cognitive decline begins to interfere with daily life
In these cases, early diagnosis can help manage symptoms and slow disease progression. “In such cases, one has to go further in the investigation of the symptoms to learn the cause and change of symptoms,” said Dr. Asma.
How Does Alzheimer’s Testing Work?
Modern diagnostic methods focus on detecting abnormal levels of two key brain proteins – amyloid and tau. These proteins naturally occur in the brain, but when they accumulate abnormally, they are linked to Alzheimer’s.
A newer method, blood-based biomarker testing using chemiluminescence immunoassay (CLEIA), allows doctors to detect these changes through a simple blood sample. This technology helps identify early disease-related changes, differentiate Alzheimer’s from other types of dementia, and further guide neurological evaluation. However, according to Dr. Asma, these tests are not meant for routine screening or preventive use, especially in healthy individuals without symptoms.
“These tests should not be considered as preventive measures or tools for routine screening, especially for younger individuals. Their main benefit is targeted use, where clinical symptoms and risk factors indicate that further investigation is necessary,” she said.
Early Warning Signs of Alzheimer’s You Must Not Ignore
Recognizing the right symptoms is key. Some common warning signs of Alzheimer’s include:
- Repeatedly asking the same questions
- Difficulty remembering recent events but recalling older memories clearly
- Forgetting familiar names or faces
- Getting lost in familiar places
- Trouble completing everyday tasks
- Mood and behavioural changes such as irritability or depression
If these symptoms persist for over six months and begin affecting daily functioning, it’s important to consult a neurologist.
According to Dr. Asma, one of the biggest mistakes people make is testing too early or unnecessarily. According to experts, including leading neurologists, the timing of testing is just as important as the test itself. Unnecessary testing not only creates false alarms but also leads to overdiagnosis and causes emotional stress. On the other hand, timely testing in the right individuals can significantly improve disease management.
