Alzheimer’s Disease: Early Signs You Shouldn’t Ignore, Causes, and Treatments
Introduction: Why Awareness About Alzheimer’s Disease Matters
Alzheimer’s disease affects millions globally and is the most common form of dementia. Alzheimer’s disease is more than just memory loss—it’s a devastating, progressive brain disorder that slowly impairs thinking, behavior, and the ability to perform even the simplest tasks. The disease accounts for 60% to 80% of dementia cases, and its impact is felt not only by the patients but also by families and caregivers.
According to Alzheimer’s Association, as of 2024, more than 6.9 million Americans aged 65 and older are living with Alzheimer’s. The numbers are growing steadily, with projections estimating a rise to nearly 13 million by 2050 unless a breakthrough treatment is found.
Early detection is crucial. Spotting the early signs can delay symptom progression and improve quality of life. In this article, we will explore:
- The early warning signs of Alzheimer’s you should never ignore
- Scientific causes and risk factors of the disease
- Diagnostic tools available today
- Effective treatments and lifestyle interventions for better living

Early Signs of Alzheimer’s Disease You Shouldn’t Ignore
Recognizing early signs of Alzheimer’s can make a significant difference in disease management. Contrary to popular belief, Alzheimer’s symptoms are not just “senior moments,” they represent real cognitive changes that should be taken seriously. The following are early signs of Alzheimer’s:
1. Memory Loss That Disrupts Daily Life: Memory loss—especially of recent events—is often the first and most noticeable symptom. Patients may forget names, appointments, or conversations and may ask the same questions repeatedly.
Alzheimer’s Association explains that “Forgetting recently learned information is one of the most common early signs of Alzheimer’s disease.”
2. Challenges in Problem Solving or Planning: People may find it difficult to work with numbers, follow recipes, or manage bills. This goes beyond typical age-related changes and points to impaired executive function.
3. Difficulty Completing Familiar Tasks: Even routine activities—like driving to a known location or remembering the rules of a favorite card game—may become confusing.
4. Confusion with Time or Place: Patients may lose track of dates, seasons, and even where they are. Some individuals forget how they got to a certain location.
5. Trouble Understanding Visual Images and Spatial Relationships: Alzheimer’s can affect the visual system. This may result in difficulty reading, judging distance, or interpreting contrast and color—affecting activities like driving.
6. Problems with Words in Speaking or Writing: People may struggle to join or follow conversations, pause mid-sentence, or use incorrect words (e.g., calling a “watch” a “hand clock”).
7. Misplacing Things and Inability to Retrace Steps: Patients may place items in unusual spots (e.g., keys in the fridge) and are unable to retrace their steps. They may also accuse others of stealing.
8. Poor Judgment and Decision-Making: A decline in decision-making ability is common—such as giving away large sums of money or neglecting personal hygiene.
9. Withdrawal from Social or Work Activities: People may lose interest in hobbies, social engagements, or work activities due to confusion or embarrassment about their memory lapses.
10. Changes in Mood and Personality: Mood swings, depression, confusion, fearfulness, or increased anxiety—especially in unfamiliar settings—can be strong indicators.

What Causes Alzheimer’s Disease?
1. Amyloid Plaques and Tau Tangles
At the biological level, Alzheimer’s is associated with two main types of brain abnormalities:
- Beta-amyloid plaques: Sticky clumps of protein that accumulate outside neurons and interfere with communication.
- Tau tangles: Twisted fibers of another protein inside brain cells that block nutrient transport and lead to cell death.
According to Mayo Clinic, these structural changes damage the hippocampus, the part of the brain essential for memory formation.
2. Genetic Risk Factors
Certain genes significantly increase the risk of developing Alzheimer’s, especially the APOE ε4 gene, which is linked to late-onset Alzheimer’s. Rare mutations in other genes such as APP, PSEN1, and PSEN2 cause early-onset forms of the disease as reported by NIH – NIA.
3. Age and Family History
- The risk doubles every 5 years after age 65.
- Having a parent or sibling with Alzheimer’s increases risk by 2 to 3 times.
4. Lifestyle and Cardiovascular Health
What affects the heart can also affect the brain. The following factors can increase Alzheimer’s risk:
- High blood pressure
- High cholesterol
- Type 2 diabetes
- Obesity
- Smoking.
The National Institute on Aging notes that “there is growing evidence that people can reduce their risk of cognitive decline by making key lifestyle changes.”

Alzheimer’s Diagnosis – How Is Alzheimer’s Detected?
There is no single test for Alzheimer’s, doctors rely on a comprehensive clinical assessment which include the following:
1. Cognitive and Neuropsychological Tests
- MMSE (Mini-Mental State Exam)
- MoCA (Montreal Cognitive Assessment)
These help assess memory, problem-solving, language, and attention.
2. Brain Imaging
- MRI or CT scans are used to rule out tumors, strokes, or trauma.
- PET scans can detect beta-amyloid plaques.
3. Biomarker Tests
Recent advances include spinal fluid tests or blood tests that can detect early Alzheimer’s biomarkers like amyloid-beta and tau proteins as noted by NIH.
4. Genetic Testing
This test is recommended only for individuals with a strong family history or early-onset symptoms.

Alzheimer’s Disease Treatment Options
While there is no specific cure for Alzheimer’s Disease, there are FDA-approved treatments and non-drug therapies that help manage symptoms and improve quality of life.
1. Medications
Cholinesterase Inhibitors
These drugs help improve communication between nerve cells:
- Donepezil (Aricept)
- Rivastigmine (Exelon)
- Galantamine (Razadyne)
NMDA Receptor Antagonist
- Memantine (Namenda): Helps regulate glutamate, a brain chemical involved in learning and memory.
New FDA-Approved Drug: Leqembi (Lecanemab)
In July 2023, the FDA granted full approval to Leqembi, the first drug to slow the progression of Alzheimer’s in its early stages (FDA.gov).
2. Non-Pharmacological Therapies
- Cognitive stimulation and memory games
- Behavioral therapy for mood swings
- Music and art therapy
- Structured routines to reduce confusion
3. Lifestyle Modifications
Numerous studies suggest that healthy habits can slow cognitive decline. These habits include:
- Exercise regularly (at least 150 minutes/week)
- Follow the Mediterranean diet
- Stay mentally and socially active
- Manage chronic diseases like diabetes and hypertension
- Prioritize sleep (poor sleep increases amyloid buildup)
“Exercise appears to directly benefit brain cells by increasing blood and oxygen flow,” according to Alzheimer’s Association.
Caring for Someone with Alzheimer’s
Caregiving can be rewarding, but also emotionally and physically draining. Here are some tips for Alzheimer’s caregivers:
- Educate yourself about the disease and its stages
- Establish a daily routine
- Use visual cues and reminders
- Promote independence where possible
- Join support groups and use local resources
- Seek respite care when needed
Resources like the Alzheimer’s Association 24/7 Helpline (1-800-272-3900) offer valuable support to caregivers.

Conclusion: The Future of Alzheimer’s Care
Alzheimer’s disease remains one of the most challenging health conditions of our time. However, with early detection, scientific innovation, and lifestyle intervention, there is real hope.
Staying informed about early warning signs and understanding the disease process are key to taking proactive steps. Whether you’re concerned about your own memory or that of a loved one, don’t ignore the signs. Seek medical attention early—because the sooner Alzheimer’s is detected, the better the options for treatment and care.
