Caring For Someone With Alzheimer’s Disease

Caring for someone with Alzheimer’s disease can be a challenging task as the disease progresses and the person’s cognitive and functional abilities decline. Alzheimer’s disease is a progressive neurodegenerative disorder that affects the brain, leading to memory loss, cognitive impairment, and behavioral changes. In this article, we will discuss the case of a person with Alzheimer’s disease, its pathophysiology, signs, symptoms, investigations, treatments, and advice for caregivers.

Case: Mrs. Johnson is a 75-year-old woman who has been experiencing memory problems for the past year. She frequently forgets appointments, names, and conversations. Her family members have noticed that she repeats herself often and has trouble finding words. Recently, she has become increasingly confused and disoriented, forgetting where she is and how to get home from familiar places. Her family has also noticed that she has become more irritable and agitated than usual. Mrs. Johnson’s family is concerned that she may have Alzheimer’s disease.


Alzheimer’s disease is a progressive neurodegenerative disorder that affects the brain, leading to the loss of neurons and the accumulation of amyloid plaques and tau protein tangles. The exact cause of Alzheimer’s disease is not yet fully understood, but genetic and environmental factors are thought to play a role. The accumulation of amyloid plaques and tau protein tangles in the brain leads to inflammation, cell death, and brain shrinkage, leading to cognitive impairment and memory loss.

Signs and Symptoms:

The signs and symptoms of Alzheimer’s disease can vary from person to person, but some common signs and symptoms include:

  • Memory loss, particularly recent memories
  • Difficulty completing familiar tasks
  • Confusion and disorientation
  • Problems with language, such as finding words or following a conversation
  • Poor judgment and decision-making
  • Changes in mood or behavior, such as depression, anxiety, agitation, or aggression
  • Loss of interest in hobbies and activities
  • Difficulty with spatial awareness and navigating familiar environments


There is no specific test to diagnose Alzheimer’s disease, but doctors may perform several tests to rule out other conditions that may cause similar symptoms. These tests may include a physical exam, neurological exam, blood tests, imaging tests such as MRI or CT scan, and neuropsychological tests to evaluate cognitive function.


While there is no cure for Alzheimer’s disease, several treatments can help manage symptoms and slow down the progression of the disease. These treatments may include medications such as cholinesterase inhibitors and memantine, which can help improve cognitive function and delay the onset of more severe symptoms. Lifestyle modifications such as exercise, a healthy diet, and social engagement may also help improve symptoms and delay the progression of the disease.

Advice for caregivers:

Caring for someone with Alzheimer’s disease can be a challenging and emotionally demanding task. Here are some dos and don’ts for caregivers:


  • Be patient and understanding
  • Create a structured routine to help the person with Alzheimer’s disease feel more secure and reduce confusion
  • Ensure safety by removing any potential hazards in the home
  • Encourage the person to engage in social activities and hobbies
  • Seek support from family, friends, and support groups


  • Don’t argue or confront the person with Alzheimer’s disease
  • Don’t take it personally if the person becomes agitated or confused
  • Don’t try to force the person to remember or perform tasks they can no longer do
  • Don’t neglect your own self-care and mental health
