Alzheimer Disease

What is Alzheimer’s Disease?

Alzheimer’s disease is a progressive neurological disorder and the most common cause of dementia—a group of symptoms affecting memory, cognitive functions, and behavior. In Alzheimer’s, brain cells gradually die off, leading to continuous cognitive decline. As it progresses, the disease interferes significantly with daily activities and personal independence. According to the Alzheimer’s Association, Alzheimer’s accounts for 60-80% of dementia cases. Most diagnoses occur after age 65, but if symptoms develop earlier, it’s called “early-onset” Alzheimer’s.

There’s currently no cure for Alzheimer’s, but treatments can help manage symptoms and slow the disease’s progression.

Signs & Symptoms of Alzheimer’s Disease

While everyone may experience occasional forgetfulness, people with Alzheimer’s show a specific set of symptoms that worsen over time, such as:

  • Memory Loss: Forgetting recent events or appointments that disrupt daily life.
  • Difficulty with Familiar Tasks: Challenges in tasks like using a microwave or preparing meals.
  • Problem-Solving Issues: Difficulty with planning or working with numbers.
  • Language Problems: Trouble with speaking or writing clearly.
  • Disorientation: Confusion about time or place.
  • Decreased Judgment: Poor decision-making, particularly around money.
  • Hygiene Decline: Neglecting personal grooming.
  • Mood and Personality Changes: Increased anxiety, confusion, or aggression.
  • Social Withdrawal: Losing interest in social activities or interactions.

Symptoms worsen as the disease progresses, and in later stages, individuals often struggle with speech, movement, and responsiveness to their surroundings.

Causes of Alzheimer’s Disease

The exact cause of Alzheimer’s remains unclear, though some risk factors have been identified:

  • Age: Most cases occur in people over 65.
  • Family History: A close family member with Alzheimer’s increases your risk.
  • Genetics: Certain genes, including the APOE-e4 gene, are linked to Alzheimer’s.
  • Health and Lifestyle Factors: Depression, smoking, cardiovascular disease, and traumatic brain injuries may also increase the risk.

Treatment of Alzheimer’s Disease

While there’s no cure for Alzheimer’s, treatments aim to ease symptoms and improve quality of life for both patients and caregivers:

  1. Medication: Certain drugs can help manage symptoms related to memory loss, confusion, and mood.
  2. Supportive Care:
    • Daycare and Activity Programs: Provide structured activities and socialization.
    • Support Groups: Offer emotional support for patients and caregivers.
    • Behavioral Management: Identifying and managing triggers that lead to irritability, anxiety, or aggression can help. Changes in environment, such as having a consistent routine or limiting sudden changes, can improve comfort.
  3. Managing Emotional and Behavioral Symptoms:
    • Emotional changes like anxiety, depression, and sleep issues are common in Alzheimer’s and may be treated with therapy or medication.
    • Modifying the environment—such as reducing noise, using familiar caregivers, and keeping routines stable—can also help patients feel more comfortable and secure.

With supportive care, early intervention, and symptom management, patients and their caregivers can achieve a better quality of life, even as the disease progresses.
