What is Dementia? How Does Rehabilitation Therapy Help?

Getting older can be scary. We worry about weaker bones and osteoporosis. We worry about losing our balance and falling, which can lead to serious injury. And many of us worry about losing our memory. Older adults and their family members should know that there is a difference between becoming a little more forgetful (what some elders call their “senior moments”) and the early signs of dementia.

Dementia is more than being forgetful; it’s categorized by the loss of cognitive skills, or the way that a person can consider and make decisions. The National Institutes of Health explain that compared to mild forgetfulness, dementia impacts daily life, interferes with decision-making, and affects every-day tasks. Dementia can affect “memory, language skills, visual perception, and the ability to focus and pay attention.” It is caused by damage to brain cells; when the brain’s cells can’t communicate properly, the way we navigate the world around us is affected.

Dementia is not always permanent. It can be caused by excess fluid in the brain (normal pressure hydrocephalus), infections, head injuries and brain tumors, or reactions to alcohol or medication. If these conditions are treated, it is possible that the dementia will recede.

While irreversible dementia isn’t curable, the process can be slowed with both medications (prescribed by your doctor) and some types of rehabilitation therapy. Specially trained speech-language pathologists help patients with dementia and memory loss retain cognitive skills as long as possible. According to the American Speech-Language-Hearing Association, the professional organization of speech-language pathologists, SLPs focus on the “cognitive aspects of communication, including attention, memory, sequencing, problem solving, and executive functioning.”

Others on the rehabilitation team can also help people with dementia. Occupational therapists can help to set up safe environments without obstacles; if the person is still living at home in the early stages of dementia, an OT can do an assessment to reduce the risk of falling and remove the risk of dangerous items (like flammable liquids or the use of the stove). OTs and SLPs can create a home environment where reminders are posted about daily tasks, helping the patient to remain independent for as long as possible. And physical therapists can work with the person to keep him or her physically active for as long as possible, which can also contribute to slowing down memory loss, while reducing the chances of falling.
