Alzheimer's Disease

Alzheimer’s disease is a progressive brain disorder that affects memory, thinking, and behaviour. Over time, it can severely impact a person’s ability to perform daily tasks and, ultimately, lead to fatal complications. While Alzheimer’s is often associated with ageing, it is not a normal part of growing older. Understanding its risks, symptoms, and management can help patients and their families cope better with this challenging condition.

What is Alzheimer’s Disease?

Alzheimer’s is the most common form of dementia, a term used for memory loss and cognitive decline severe enough to interfere with daily life. The disease damages brain cells, leading to a gradual decline in memory, reasoning, and personality changes. As it progresses, it affects vital brain functions, making even basic tasks like eating or speaking difficult.

Symptoms of Alzheimer’s Disease

The symptoms of Alzheimer’s worsen over time. They can be categorised into early, middle, and late stages:

Early Stage (Mild Alzheimer’s)

  • Forgetfulness (misplacing items, forgetting names)
  • Difficulty planning or organising
  • Trouble finding the right words
  • Mild confusion in familiar places

Middle Stage (Moderate Alzheimer’s)

  • Increased memory loss (forgetting personal history)
  • Difficulty recognising family and friends
  • Mood swings, anxiety, or aggression
  • Trouble with basic tasks (dressing, bathing)

Late Stage (Severe Alzheimer’s)

  • Loss of ability to communicate
  • Inability to recognise loved ones
  • Difficulty swallowing and walking
  • Complete dependence on caregivers

Why is Alzheimer’s Fatal?

Alzheimer’s itself does not directly cause death, but the complications arising from severe brain damage can be life-threatening. In advanced stages, patients may experience:

  • Infections: Pneumonia due to difficulty swallowing
  • Malnutrition & dehydration: Forgetting to eat or drink
  • Injuries: Falls due to mobility issues
  • Organ failure: Due to prolonged immobility

These complications weaken the body, making patients vulnerable to fatal health crises.

What Causes Alzheimer’s?

While the exact cause is unknown, several factors contribute to its development:

  • Age: Most cases occur after 65.
  • Genetics: Family history increases risk.
  • Brain Changes: Plaques (protein buildup) and tangles damage brain cells.
  • Lifestyle Factors: Poor diet, lack of exercise, smoking, and uncontrolled diabetes may raise risk.

Can Alzheimer’s Be Prevented or Delayed?

There is no sure way to prevent Alzheimer’s, but healthy habits may help reduce risk or slow progression:

  • Stay Mentally Active: Reading, puzzles, learning new skills.
  • Exercise Regularly: Improves blood flow to the brain.
  • Eat a Brain-Healthy Diet: Mediterranean diets (rich in fish, nuts, vegetables).
  • Control Chronic Conditions: Manage diabetes, high blood pressure, and cholesterol.
  • Stay Socially Engaged: Reduces depression and cognitive decline.

How is Alzheimer’s Treated?

While there is no cure, treatments can help manage symptoms:

  • Medications: Help slow memory loss (e.g., Donepezil, Memantine).
  • Therapies: Cognitive exercises, speech therapy.
  • Supportive Care: Safe home environment, caregiver assistance.

Early diagnosis is crucial for better management. If you or a loved one experience memory problems, consult a doctor.

When to Seek Help?

If you notice persistent:

  • Memory lapses affecting daily life
  • Confusion with time or place
  • Mood or personality changes
  • Difficulty completing familiar tasks

It’s important to consult a neurologist for evaluation. Early intervention can improve quality of life. If you suspect Alzheimer’s symptoms in yourself or a loved one, Apollo 24|7 offers expert neurologists for diagnosis and care. Schedule a consultation or cognitive test today for timely support.

Conclusion

Alzheimer’s is a devastating disease, but understanding its progression and seeking early medical help can make a difference. With proper care, patients can maintain a better quality of life for longer. If you have concerns, don’t hesitate to reach out to a healthcare professional.
