When someone’s memory begins to slip, or familiar tasks turn into unexpected challenges, the changes can ripple through the lives of an entire family. Alzheimer’s disease, a condition that millions face, brings with it a unique set of symptoms that can touch every aspect of daily life. 

If you’re supporting someone through this, it’s helpful to understand the “4 A’s” of Alzheimer’s symptoms, which include:

  • Amnesia
  • Aphasia
  • Apraxia
  • Agnosia

These symptoms reflect significant changes in memory, language, motor skills, and recognition. By understanding what your loved one may be experiencing, senior living communities can support them and help them thrive in body, mind, and spirit. 

What Is Alzheimer’s Disease?

Alzheimer’s disease is a progressive neurological condition that gradually causes the brain to shrink and lose critical connections. The significant changes in the brain lead to memory loss, difficulties with thinking capabilities, and challenges with behavioral regulation. 

It’s the most common cause of dementia. It affects not only the person experiencing these changes but also their family and support network.

Over time, Alzheimer’s can impact daily routines. Simple tasks like making breakfast, buttoning a sweater, or recognizing familiar faces may become challenging. Some may eventually need full-time care to support their safety and well-being.

Alzheimer’s progresses in stages, and we can look at those stages using the 4 A’s of Alzheimer’s symptoms.

Exploring the 4 A’s of Alzheimer’s Symptoms

The evolving symptoms and obstacles related to the progression of Alzheimer’s can be summarized using a framework known as the 4 A’s of Alzheimer’s, which are:  

  • Amnesia
  • Aphasia
  • Apraxia
  • Agnosia

It’s a straightforward framework that can help families and loved ones recognize issues and seek support when necessary.

Memory Shifts with Amnesia

Some forgetfulness as we age is normal. However, one of the earliest and most noticeable changes in Alzheimer’s is amnesia, which involves not just forgetfulness but significant memory loss. 

Someone may have trouble remembering recent conversations or appointments, later extending to older memories. Their memory loss may spark moments of confusion, like not recognizing familiar friends or forgetting cherished family events.

There are 2 facets of amnesia within Alzheimer’s:

  • Retrograde amnesia affects older memories from before the onset of Alzheimer’s
  • Anterograde amnesia makes it hard to form new memories

The good news is that there are ways to support someone experiencing amnesia:

  • Keep a consistent daily routine to create familiarity
  • Use visual aids, like labeled drawers or memory journals
  • Brightly colored or easily identifiable items can help minimize confusion

Memory-focused care programs can also foster a sense of independence while providing structured support.

Language Challenges with Aphasia

Aphasia is another hallmark of Alzheimer’s and affects the ability to express or understand language. Someone might struggle to find the right word, recall names, or form sentences. Over time, even understanding speech and written text can become difficult.

If you’re communicating with someone experiencing aphasia, try these approaches:

  • Speak slowly & use simple, clear language
  • Incorporate hand gestures or visual aids to illustrate your message
  • Allow extra time for responses & reactions

When words seem out of reach, focus on nonverbal communication. Smiles, touch, and positive body language can convey warmth and connection beyond words.

Motor Skill Difficulties with Apraxia

Apraxia targets motor skills, causing disjointed movements that interfere with everyday tasks. 

Even when your loved one has the desire or knowledge to perform an act, the connection between the idea and execution can vanish. Your loved one might struggle to tie shoelaces, stir a drink, or button a favorite sweater.

To provide support for someone with apraxia:

  • Break tasks into smaller, step-by-step instructions
  • Make activities more manageable with tools like slip-on shoes or adaptive utensils
  • Focus on creative, low-pressure activities to keep frustration at bay

Creating a patient, understanding environment can help preserve joy in familiar activities and maintain a comforting level of independence.

Recognition Issues with Agnosia

Agnosia is the failure to recognize information coming from your senses, such as touch, sight, taste, smell, and hearing, despite the senses functioning properly. 

Agnosia can create challenges with recognizing a loved one’s face, identifying a once-familiar object, or even navigating spaces they used to know.

To support someone with agnosia:

  • Use photo labels on household items to reinforce familiarity
  • Incorporate scents, textures, or event-specific triggers to evoke recognition
  • Provide verbal reassurances like, “This is your favorite mug,” to bridge the gap

Even when recognition fades, emotional connections endure. A favorite song, a familiar scent, or a gentle touch can still spark moments of comfort and grounding.

Supporting Your Loved One Through It All

Supporting someone through Alzheimer’s means adapting to profound changes while finding ways to preserve joy and connection. It’s important to remember that these symptoms don’t define your loved one. 

Beneath the challenges, their essence remains, and shared moments of love and care will shine through.
