How Sensory Stimulation Can Help Alzheimer’s

Originally used as a therapy in Europe, sensory stimulation has gained prominence in the United States as a treatment for Alzheimer’s disease.How Sensory Stimulation Can Help Alzheimer's

Using everyday objects, therapists can trigger emotions and memories in seniors who have lost their ability to connect with the world around them.

Sensory Stimulation Therapy

Sensory stimulation uses everyday objects to arouse one or more of the five senses (hearing, sight, smell, taste and touch), with the goal of evoking positive feelings.

Used in Europe since the 1960s, this therapy was originally designed to help people with learning disabilities. It was a way for them to explore a safe, stimulating environment that provided age-appropriate and enjoyable activity.

Since then, the therapy has become widely used to treat other conditions, including:

  • Alzheimer’s
  • Autism
  • Brain injuries
  • Chronic pain
  • Other forms of dementia

Ways Sensory Stimulation Can Affect Alzheimer’s

As Alzheimer’s progresses, a senior’s ability to communicate and perform everyday activities declines. Giving these seniors means to express themselves, when they can no longer do so with words, can help them feel safe and relax. This can improve their:

  1. Mood
  2. Self-esteem
  3. Well-being

Additionally, by drawing attention to a particular item, sensory stimulation encourages memories and responses from seniors suffering from Alzheimer’s:

For instance, art or photos can trigger emotions and memories for seniors who no longer speak. A senior who has not expressed a word in months might suddenly smile or want to pick up a pencil and draw. That art form eventually can become a means for the senior to communicate, either through personal works of art or simply by sharing the experience.

Ways Sensory Stimulation Engages Seniors

Everyday Sensory Cues

The Canadian Association of Occupational Therapists (CAOT) explains that sensory stimulation works best when it uses familiar objects and focuses on one sense at a time. Good sensory cues include:

  • Familiar foods and clothing
  • Natural materials, such as flowers
  • Sensory-rich materials, such as wood grains and grooming tools

In practice, the item is introduced to the person with Alzheimer’s, and the therapist provides reassuring nonverbal and verbal cues to stimulate a response.

The CAOT gives an example of the smell of toast in the morning. A therapist presents the toast, removing all other stimuli, asks questions related to the toast and might even help the senior bring the toast to his or her mouth.

Sensory Stimulation Activities

Activities involved in sensory stimulation are often linked to interests the person had prior to dementia, and can help build a connection to everyday life. According to the Alzheimer’s Association, sensory stimulation activities might include:

  • Bringing in objects the senior does not normally have around, such as sand, seashells or other items
  • Giving a hand massage
  • Taking a short walk
  • Talking and reading aloud to the senior
  • Providing a change of scenery by taking the senior outdoors

Depending on how the senior reacts, the therapist might alter the activity or switch to a different sense to find the stimuli that is going to inspire a response.

Sensory stimulation is intended to bring enjoyment to seniors with the disease, reduce their anxiety and depression, and increase their social interaction.

Though activities are aimed at seniors, they are still shared with a caregiver, loved one or therapist. Those shared experiences and memories can help bring seniors back to a time that they remember fondly, which can help them feel meaningful again.

    Sensory stimulation actually occurs anytime sense organ is activated. Sound activates the hearing sense. Light activates the sense of sight. Molecules in the air can stimulate smell. And
    sensory stimulation doesn’t always evoke positive feelings. Sensory input, especially at high intensity can cause psychological and even physical pain.

    You must have meant to say that “sensory stimulation therapy uses everyday objects… with the goal of evoking positive feelings.” Simple sensory stimulation is neutral and potentially evokes as many negative as positive feelings.

    Then you go and mix up the benefits of sensory stimulation therapy
    with other forms of alternative therapy, like art therapy and reminiscence therapy.

    Great article … Appealing to the senses when someone has dementia has been a winner every time in my career. I work with folks in a Rec Therapy environment and provide a sensory activity everyday. It allows them to respond with individuality. They have made comments at several instances that the sensory activity gave them a thought process that reminded them of a memory from years ago. Some have even commented that it allowed them to “feel” again. Glad that this is going more main stream… I expect to see success.

    Recently promoted from CNA to Activities Assistant I have engaged daily with Sensory Stimulation as a regular scheduled activity for my community in Memory Support.
    I have seen the benefits and the difference in the entire community throughout each day. My residents who once sat alone waiting for the next meal time and nap are instead socially interacting dancing and singing. And mealtime arrives to fast.
    We do a range of sensory activities one example and a unforgettable experience of complete wonder joy and reminiscing was are bubble fun in the sun.
    We went outside to our covered patio that overlooks a beautiful scenery of green trimmed grass bushes and flowers rabbits in the quart yard and birds singing. We set up 2 bubble machines ( in toy section at Walmart) and as they began to blow out hundreds of cotton candy smelling bubbles that glowed rainbow colors from the sun and flew way up above the building every resident present was in a magic world of fond childhood memories and smiles bloomed on every face. Some residents reached out to catch them others with amazement looked and laughed as a few kissed their nose . And amazing moment indeed triggering sensory stimulation of smell sight touch and beautiful memories
