What Is the Interlocking Finger Test for Dementia?

As a caregiver, navigating the complexities of cognitive decline can be challenging. There’s a lot for any one person to know when providing valuable care for their loved one. One such useful piece of knowledge is understanding the tools and tests used to assess cognitive health.  

The Interlocking Finger Test is a method used for screening dementia in individuals with Parkinson’s disease. This test helps assess an individual’s motor coordination, comprehension, execution, and memory recall. 

What is Parkinson’s Dementia?

Dementia is not a single condition, but a general term used to describe a range of symptoms associated with cognitive decline.

Dementia is a progressive disorder, which means that symptoms worsen over time. The nature of the condition means that dementia can impact daily living, making it difficult for individuals to perform routine tasks, maintain relationships, and/or live safely and independently. 

Anyone can be at risk of developing dementia, but factors like age, family history, and genetics can increase an individual’s risk of developing the condition. 

Parkinson’s disease dementia is a type of dementia that may develop in individuals with Parkinson’s disease. This condition is primarily known for affecting movement. Parkinson’s dementia occurs when changes to the brain associated with Parkinson’s disease also affect cognitive functions, leading to problems with memory. 

Symptoms of Parkinson’s dementia typically appear after several years of living with Parkinson’s disease. Symptoms vary between individuals, but they may include: 

• Cognitive Impairments: This includes difficulty with planning, organizing, decision making, focus and concentration, and memory issues. 
• Visual Hallucinations or Paranoia: This includes seeing things that aren’t there.
• Decreased Fine Motor Skills: Symptoms associated with motor skills include muscle stiffness, body tremors, and slow movement. 

To understand the level of cognitive impairment, the associated symptoms, and how their symptoms may impact their living, Parkinson’s disease dementia is broken down into stages. This helps caregivers, family members, and healthcare staff provide the appropriate level of care for an individual experiencing dementia.  

The Interlocking Finger Test

The interlocking finger test (ILFT) is a simple, non-invasive screening tool used to assess an individual’s level of cognitive function. This screening test is one of the ways that dementia can be diagnosed in individuals with Parkinson’s disease. 

During the ILFT test, the professional conducting it will make a variety of simple hand gestures. The patient is then asked to imitate these gestures as accurately as possible. 

The ILFT primarily helps in evaluating the following cognitive abilities:

• Motor Coordination: Difficulty in interlocking fingers may indicate issues with motor coordination, which is often present in dementia.
• Comprehension and Execution: The ability to understand a set of instructions and then execute a task correctly reflects the individual’s cognitive processing speed and comprehension.
• Memory Recall: The test can also provide insight into the individual’s short-term memory and ability to follow simple commands.

The test itself is straightforward, though individuals in later stages of Parkinson’s dementia may find it to be challenging. This is because Parkinson’s dementia, which affects a person’s memory, coordination, and motor skills, their ability to interlock their fingers correctly becomes more difficult.

When to Consider Memory Care

Due to the progressive nature of cognitive decline, families and caregivers must recognize that there may come a time when their loved one is unable to live independently and safely.

Memory care is a specialized form of long-term care that is designed to meet the unique needs of individuals who are experiencing Alzheimer’s disease, Parkinson’s disease, dementia, and other cognitive impairments. 

These communities provide professional 24/7 care and support to residents in a safe environment. Their training allows them to provide the appropriate level of care for residents no matter their stage of cognitive decline. 

Some of the services and amenities provided in memory care communities include: 

• 24/7 Care and Support: Professional caregivers are available around the clock to assist residents with daily activities and medical needs such as medication management.
• Personalized Care Plans: At Peregrine Senior Living, we recognize that all residents are unique. This is why each resident receives an individualized care plan. 
• Therapeutic Activities and Social Connections: Engaging in activities like music therapy, art therapy, and memory games can help stimulate memory and cognitive function, and encourage social connections. 
• Safe Environment: Individuals experiencing cognitive decline are prone to wandering, falls, and injuries. Our community is designed with these health measures in mind, and provides both additional support and wide spaces in order to promote the well-being and safety of our residents. 

There is no definitive time when memory care should be considered. Every individual is different. The safety and well-being of your loved one is of the utmost importance. Memory care is encouraged when your loved one can no longer safely live independently.

Other considerations for memory care include: 

• Safety: Memory loss means that individuals may require assistance in taking medication and preparing meals. Some individuals are prone to wandering, falls, or even forgetting to turn off their home appliances, which can create a safety hazard.
• Specialized Care: Professional caregivers are trained to handle the unique challenges of dementia, providing better care than what might be feasible at home. Some individuals may require full-time assistance with daily living activities, which can be difficult for one caregiver to manage. Memory care includes a team of professionals who can help whenever they are needed.
• Caregiver Burnout: Caring for a loved one takes a community. It’s a lot of work for one person to take on. Caregiver burnout is a serious condition that can impact the level of care provided to a loved one. Professional care can offer support and reduce the chances of burnout.
