New Delhi, 21 September, 2025: Every year, World Alzheimer’s Day (September 21st) reminds us of the urgent need to understand dementia and support those affected by it. In 2025, the spotlight is on early detection, as experts stress that catching the warning signs of Alzheimer’s disease at an early stage can make a big difference in managing symptoms and planning care.
Neurologists across the globe emphasize that families—especially adult children caring for ageing parents—must stay alert to subtle behavioral and cognitive changes. Alzheimer’s does not appear suddenly; instead, it creeps in gradually. Recognizing the first symptoms can help secure timely diagnosis, start treatment earlier, and improve quality of life.
This article explores the 8 early warning signs of Alzheimer’s disease that neurologists recommend monitoring in ageing parents, along with steps families can take.
What Is Alzheimer’s Disease?
Alzheimer’s disease is a progressive neurological disorder and the most common cause of dementia. It leads to memory loss, difficulty in thinking, impaired judgment, and eventually, the loss of independence.
The disease occurs when abnormal proteins (amyloid and tau) build up in the brain, disrupting communication between neurons and causing them to die. Over time, this leads to shrinkage of brain tissue and worsening symptoms.
While age is the biggest risk factor, Alzheimer’s is not a normal part of ageing. Detecting early signs can help slow down progression through treatment and lifestyle interventions.
Why Early Detection Matters
Neurologists highlight several reasons why early recognition of Alzheimer’s is critical:
- Better symptom management through medications and therapies.
- Planning ahead for care, finances, and safety.
- Reduced caregiver stress when families understand the condition.
- Improved patient well-being by promoting brain health and lifestyle changes.
On World Alzheimer’s Day 2025, the message is clear: don’t ignore the early signs.
8 Early Warning Signs of Alzheimer’s to Watch For
1. Memory Loss That Disrupts Daily Life
It’s normal to forget names or misplace keys occasionally. But when your parent repeatedly forgets recently learned information, asks the same question multiple times, or relies heavily on notes and reminders, it could indicate Alzheimer’s-related memory decline.
2. Difficulty Planning or Solving Problems
Early Alzheimer’s can affect executive functions. If your parent struggles to follow a familiar recipe, pay bills, or manage finances despite handling them well in the past, this is a red flag.
3. Trouble Completing Familiar Tasks
Simple activities like driving to the grocery store, remembering how to use a phone, or performing routine household chores may suddenly become challenging. This indicates the disease is interfering with daily tasks.
4. Confusion About Time or Place
Alzheimer’s often causes disorientation. Parents may forget what day it is, lose track of seasons, or become confused about where they are—even in familiar places. In advanced cases, they may believe they are living in the past.
5. Problems With Words and Communication
Neurologists often point out language difficulties as an early symptom. People may pause mid-conversation, struggle to find the right word, or repeat themselves. Written communication may also become harder.
6. Misplacing Things and Losing the Ability to Retrace Steps
It’s common to misplace items occasionally. But if your parent frequently puts objects in unusual places (like storing keys in the fridge), accuses others of stealing, or cannot retrace their steps to find the item, it may be Alzheimer’s.
7. Withdrawal From Work or Social Activities
Social isolation is a warning sign. A once-active parent may avoid hobbies, social gatherings, or conversations because they feel confused or embarrassed about their difficulties. This withdrawal often worsens depression.
8. Changes in Mood, Personality, or Judgment
Alzheimer’s can cause dramatic personality changes. Patients may become anxious, suspicious, or easily upset. Poor judgment is also common—such as giving away money carelessly or neglecting personal hygiene.
Differentiating Alzheimer’s From Normal Ageing
Families often confuse normal ageing with Alzheimer’s. Here’s how to tell the difference:
- Normal Ageing: Occasionally forgetting names or appointments but remembering later.
- Alzheimer’s: Forgetting recent events completely and not recalling them even with cues.
- Normal Ageing: Sometimes having difficulty finding words.
- Alzheimer’s: Regularly struggling with conversations and losing the thread of discussion.
- Normal Ageing: Misplacing items occasionally.
- Alzheimer’s: Misplacing items frequently and being unable to retrace steps.
Recognizing these distinctions helps families avoid dismissing serious symptoms as “just old age.”
When to Seek Medical Help
If you notice two or more of the above warning signs in your parents, it’s important to consult a doctor. A neurologist may conduct:
- Cognitive tests for memory and problem-solving.
- Brain imaging (MRI, CT, or PET scans).
- Blood tests to rule out other causes like thyroid issues or vitamin deficiencies.
- Neurological examinations to assess brain function.
Early diagnosis doesn’t just confirm the condition—it also opens the door to treatments that may slow progression.
Supporting Ageing Parents With Early Alzheimer’s
Caring for a parent showing early Alzheimer’s signs can be overwhelming. Here are some strategies recommended by experts:
- Encourage medical evaluation for proper diagnosis.
- Create structured routines to reduce confusion.
- Promote brain health with physical activity, reading, and puzzles.
- Simplify the home environment with labels, reminders, and organization.
- Offer emotional reassurance instead of correcting mistakes harshly.
- Stay patient and empathetic, as frustration only increases distress.
- Connect with support groups for caregivers and families.
Preventive Lifestyle Measures
While there’s no guaranteed way to prevent Alzheimer’s, neurologists emphasize lifestyle habits that may reduce risk:
- Maintain a balanced diet (Mediterranean-style diet rich in vegetables, whole grains, nuts, and fish).
- Engage in regular exercise (walking, yoga, or aerobics).
- Stay socially connected to prevent isolation.
- Keep the brain active through learning, reading, and puzzles.
- Prioritize sleep and stress management.
- Control chronic health issues like diabetes and hypertension.
These steps may not stop Alzheimer’s, but they can protect overall brain health.
On World Alzheimer’s Day 2025, neurologists urge families to pay close attention to the 8 early warning signs of Alzheimer’s in ageing parents. Spotting these symptoms early is not only about diagnosis—it’s about giving loved ones the best possible care, dignity, and quality of life.
Alzheimer’s is not just memory loss—it is a progressive brain disease that reshapes lives. With awareness, compassion, and proactive support, families can better navigate the challenges ahead while honoring and caring for their loved ones.
