10 Early Warning Signs of Alzheimer’s

It is a neurodegenerative disorder characterized by a loss of memory, thinking, and behavior-usually progressive in nature. Most diagnoses of Alzheimer’s disease benefit from early warning signs. This will aid in early planning for the future, consider treatment options, and provide the best quality of life for both the person with Alzheimer’s and his caregivers. The following ten early warning signs are research-based and founded on guidance provided by leading health organizations.

1. Memory Loss That Disrupts Daily Life
   One of the most common early signs of Alzheimer’s is memory loss, especially in newly learned information. It might manifest as repeatedly asking the same question, relying increasingly on memory aids such as notes and reminders, or calling on family members for more assistance with tasks for which one was self-sufficient. According to the Alzheimer’s Association, the memory loss in those suffering from Alzheimer’s is not comparable to the normal age-related changes. While it is normal to sometimes forget a name or an appointment, a person with Alzheimer’s is often unable to remember important information. (Alzheimer’s Association, 2023).
2. Difficulty with Planning or Problem Solving
   Some individuals with Alzheimer’s have brain executive functioning where it becomes hard to stick with a plan or deal with tasks that require structured effort and attention. For instance, paying bills, following a recipe, or keeping track of monthly expenses becomes challenging. Problem-solving has been documented to become diminished due to cognitive impairment in Alzheimer’s through changes occurring in the frontal lobes responsible for issues such as decision-making and logical thinking.
3. Difficulty in Performing Familiar Tasks
   As Alzheimer’s disease progresses, doing everyday activities such as cooking, telephoning, or using household electronics poses a challenge. Now the smallest daily tasks will pose problems for the patients in completion of these activities they could earlier do comfortably. According to a study in The Lancet Neurology, difficulty in performing everyday activities has been attributed to a loss of procedural memory and other cognitive skills necessary to execute sequential activities (Hodges & Patterson, 2007).
4. Disorientation to Time or Place
   People with Alzheimer’s may forget the date, the season of the year, or the time of day. They might feel confused about the location they are in or how they got there. They may feel disoriented in familiar places or remind themselves with notes to keep them oriented. Temporal disorientation can be very common because of changes in brain areas responsible for spatial and temporal awareness, such as the hippocampus, which often gets affected in Alzheimer’s disease.
5. Difficulty Understanding Visual Images and Spatial Relationships
   Alzheimer’s can cause degeneration in vision and spatial awareness, leading to inability to judge distance, distinction of colors, or interpretation of images in daily life, such as difficulties with driving, walking, or reading. Indeed, one study from Neurobiology of Aging had shown that in a group of Alzheimer’s patients, the visual cortex was also compromised, leading to defects in depth perception and contrast sensitivity (Kurylo et al., 1996).
6. Language, Speaking, or Writing Problems
   Language abilities of an individual can also be affected by Alzheimer’s; a person may quickly forget words or may find it challenging to find the right words while conversing. They stop during midspeech or cannot join a conversation. A person suffering with Alzheimer’s may use strange words to refer to ordinary things like Monday, family, friends, and groceries. According to research, areas of the brain that control the language, namely Broca’s area and Wernicke’s area, are damaged, thereby causing speech problems and difficulties in comprehension.
7. Misplacing Items-where and whereabouts-and Loss of Ability to Retrace Steps
   Everyone loses things from time to time, but people with Alzheimer’s tend to put things in strange places and then can’t find them. They may then accuse others of stealing their belongings, particularly as the memory loss becomes worse. Researchers have found that this often is due to a dysfunction in the hippocampus, which is responsible for the formulation and retrieval of new memories (Squire et al., 2004).
8. Less or No Judgment
   Individuals with Alzheimer’s disease show poor judgment or decision-making. For example, they may give away a very large sum of money with poor judgment about financial investments or become neglectful in personal hygiene. Poor judgment in Alzheimer’s disease may be the result of prefrontal cortex involvement, which is responsible for higher-order abilities related to decision-making and impulse control. Bishop et al. (2000) To date, early identification of poor judgment may be critical for preventing risky behavior and maintaining safety.
9. Withdrawal from Work or Social Activities
   As the disease of Alzheimer’s progresses, individuals may become indifferent to hobbies, social activities, or work. This could stem from feelings of embarrassment over problems with memory, inability to keep up, or perhaps simply lack of motivation to participate. Social withdrawal can accelerate cognitive decline; it has also been shown that isolation is linked with a faster rate of increase in Alzheimer’s symptoms. Continued engagement in social and mental activities might promote cognitive health.
10. Mood and Personality Changes
    Alzheimer’s can also lead to severe changes in mood and personality, possibly causing anxiety, confusion, depression, or irritability. Individuals can easily get upset, suspicious, or fearful. Such behavioral changes can be due to alterations in the limbic system of the brain, which governs emotion, and in the frontal lobes, which are associated with personality and behavior (Rosenberg et al., 2015).

Importance of Identification of Early Signs

These are the early warning signs for Alzheimer’s, which require medical guidance. It is not that one symptom alone gives the signal for Alzheimer’s, but if most of them do, then a doctor should be consulted. The benefit of early diagnosis is that it allows planning, and access to possible treatments that may delay the progress of symptoms and improve quality of life. For example, medications containing cholinesterase inhibitors like donepezil and NMDA antagonists such as memantine can help with early to middle-stage symptoms of the disease Alzheimer.

What to Do if You Notice These Signs

If you or someone you know is experiencing these signs, consider the following steps:

1. Consult a Healthcare Professional: A physician can help evaluate symptoms, perform cognitive tests, and rule out other conditions with similar signs.
2. Get a Brain Health Assessment: Various brain imaging techniques, like MRIs or PET scans, can detect brain changes related to Alzheimer’s and provide clarity on diagnosis.
3. Consider Support Groups and Resources: Many communities offer resources and support groups for people with Alzheimer’s and their families, providing a network of care and guidance.
4. Encourage Healthy Habits: Research shows that regular physical activity, social interaction, and a balanced diet rich in antioxidants may help delay cognitive decline (Scarmeas et al., 2006).
5. Educate Yourself and Others: Understanding Alzheimer’s helps in early recognition, better support for individuals affected, and advocacy for research and resources.

Current Research and Future Directions

Research into Alzheimer’s disease is ongoing, with new findings aiming to improve diagnosis and treatment options. Scientists are exploring biomarkers, such as tau and amyloid proteins, that could be detected in the blood or cerebrospinal fluid to diagnose Alzheimer’s before symptoms emerge (Bateman et al., 2012). Gene therapy, immunotherapy, and advancements in medications show potential in slowing disease progression. Early diagnosis combined with cutting-edge research could mean a brighter future for Alzheimer’s patients and their families.
