Understanding Dementia Progression, Hospice Eligibility, and the Importance of the FAST Score

Dementia: A Complex Journey

Dementia is a complex and debilitating condition characterized by cognitive decline, memory loss, and impaired daily functioning. As the disease progresses, patients often reach an advanced stage where their functional abilities decline significantly. The Functional Assessment Staging Tool (FAST) serves as a valuable instrument for assessing and staging the progression of dementia, particularly in its advanced stages. This blog post aims to delve into the FAST, elaborate on the score needed for hospice eligibility, describe common characteristics of end-stage dementia, and touch upon different types of dementia and highlight how the decline can vary among these types.

FAST Score: Tracking Dementia Progression

The Functional Assessment Staging Tool (FAST) is a widely recognized and validated instrument used to assess the functional abilities of individuals with dementia. It was developed by Barry Reisberg, MD, and his colleagues in the late 1980s to provide a structured framework for staging the progression of Alzheimer’s dementia based on functional impairment. The FAST consists of seven stages, each representing a distinct level of cognitive and functional decline.

Overview of the FAST Score stages and their corresponding descriptions in the progression of dementia.

Stage 1: No Cognitive Decline

• At this stage, there are no apparent cognitive or functional impairments.
• Individuals perform daily activities without difficulty and have a normal memory.
• There are no observable symptoms of dementia.

Stage 2: Very Mild Cognitive Decline

• Slight cognitive changes may be observed, but they are often attributed to normal aging.
• Forgetfulness regarding names, misplacing objects, or difficulty finding the right words may occur.
• ADLs remain unaffected, and individuals can still manage daily tasks independently.

Stage 3: Mild Cognitive Decline (Early Stage)

• Early signs of cognitive impairment become more noticeable.
• Memory lapses become more frequent and extend beyond normal aging.
• Challenges in work or social settings may arise due to memory issues.
• ADLs are generally preserved, but individuals might need assistance with complex tasks.

Stage 4: Moderate Cognitive Decline (Mid-Stage)

• Deficits in cognitive function become more apparent.
• Memory loss intensifies, and individuals struggle with remembering recent events or conversations.
• ADLs are significantly affected; assistance is required for tasks such as managing finances, cooking, and planning activities.
• Problem-solving abilities, attention span, and language skills decline.

Stage 5: Moderately Severe Cognitive Decline

• Individuals experience notable cognitive and functional deficits.
• Memory continues to deteriorate, and they may not remember personal details or addresses.
• Confusion about time and place is common.
• ADL dependency increases; individuals require help with dressing appropriately, bathing, and maintaining hygiene.

Stage 6: Severe Cognitive Decline

• Profound cognitive impairment is evident.
• Individuals struggle to recognize loved ones and may experience personality changes.
• Inability to recall recent events or personal history.
• ADLs become highly compromised; assistance is necessary for feeding, toileting, and other basic tasks.

Stage 7: Very Severe Cognitive Decline or End Stage Dementia with Subclassification A-F. 

• Total functional dependence; individuals are unable to perform any ADLs without assistance.
• Challenges with mobility, swallowing, and maintaining bodily functions arise.
• Subclassification A-F:
  • 7A: Speaks 5-6 words during the day
  • 7B: Speaks only 1 word clearly 
  • 7C: No longer can walk without assistance 
  • 7D: Can no longer sit up 
  • 7E: Can no longer smile
  • 7F: Can no longer hold their head up 

The FAST score assists healthcare professionals, caregivers, and families in assessing the level of cognitive and functional decline, enabling them to provide appropriate care and support tailored to each stage. By understanding the implications of each stage, individuals can ensure the best quality of life for those living with Alzheimer’s dementia while navigating the challenges that arise throughout its progression. It's important to note that while the FAST provides a structured framework for understanding Alzheimer’s dementia progression, the exact experience can vary among individuals. Additionally, the rate at which individuals progress through the stages may differ based on factors such as the type of dementia, overall health, and individual characteristics.

Hospice Eligibility and FAST Score

Hospice care is a specialized form of medical care aimed at providing comfort, support, and quality of life for individuals with life-limiting illnesses, including advanced dementia and neurocognitive disorders. Determining hospice eligibility involves a comprehensive assessment of the patient's medical condition, functional status, and prognosis. The Functional Assessment Staging Tool (FAST) score, along with Medicare's Local Coverage Determination (LCD) for dementia and neurocognitive disorders, plays a significant role in determining hospice eligibility for individuals with these conditions. Generally, a FAST score of 7A or higher is considered indicative of end-stage dementia, indicating that the individual's cognitive and functional impairments have reached a point where specialized end-of-life care is necessary.

Individuals with a FAST score of 7A or higher often require assistance with most, if not all, activities of daily living (ADLs). These activities may include eating, dressing, bathing, toileting, and mobility. Additionally, they may experience communication challenges, memory loss, and an overall decline in cognitive abilities. The FAST score helps healthcare professionals, caregivers, and families make informed decisions regarding the appropriate level of care, including hospice services, to ensure the individual's comfort and well-being.

Medicare, the federal health insurance program in the United States, covers hospice services for eligible beneficiaries. Medicare's Local Coverage Determination (LCD) provides guidelines for determining hospice eligibility based on the specific medical condition, prognosis, and functional status of the individual. For individuals with dementia and neurocognitive disorders, the LCD outlines the criteria that need to be met for hospice coverage.

The LCD typically includes criteria related to cognitive impairment, functional decline, and the overall trajectory of the disease. It may require documentation of a qualifying FAST score, indicating the individual's advanced stage of dementia. Additionally, the LCD may consider other factors such as recurrent infections, declining nutritional status, and overall decline in medical condition. Meeting these criteria ensures that individuals receive the appropriate level of care, focusing on comfort and symptom management.

Types of Dementia & Their Progression Patterns

Dementia is an umbrella term that encompasses several types of neurodegenerative disorders, each with its unique characteristics, underlying causes, and progression patterns. Understanding these different types of dementia is necessary for providing appropriate care and support to individuals affected by the condition. Let's delve into the various types of dementia and their distinct features:

1. Alzheimer's Disease:

• Characteristics: Alzheimer's disease is the most common type of dementia. It is characterized by the accumulation of abnormal protein aggregates, including beta-amyloid plaques and tau tangles, in the brain.
• Progression: Alzheimer's disease typically begins with subtle memory loss and difficulty in finding words. As it progresses, cognitive functions such as problem-solving, language, and reasoning are affected. Individuals may become disoriented, experience personality changes, and struggle with complex tasks. In the later stages, severe cognitive impairment and functional dependence emerge.

2. Vascular Dementia:

• Characteristics: Vascular dementia results from impaired blood flow to the brain due to conditions like strokes or small vessel disease. It can manifest suddenly or progressively.
• Progression: Vascular dementia often follows a stepwise or fluctuating progression pattern. Individuals may experience memory problems, executive function deficits, and difficulties with attention and concentration. The course of the disease depends on the location and extent of brain damage caused by vascular events.

3. Lewy Body Dementia (LBD):

• Characteristics: Lewy body dementia is characterized by the presence of abnormal protein deposits called Lewy bodies in the brain. It is closely related to Parkinson's disease and shares some symptoms.
• Progression: LBD exhibits fluctuating cognitive abilities, visual hallucinations, and motor symptoms such as tremors and stiffness. Individuals may experience changes in attention and alertness, leading to confusion and difficulty with memory recall. Sleep disturbances and visual hallucinations are common features.

4. Frontotemporal Dementia (FTD):

• Characteristics: FTD primarily affects the frontal and temporal lobes of the brain, leading to changes in behavior, personality, and language.
• Progression: FTD often presents with alterations in social behavior, emotional blunting, and disinhibition. Language difficulties, including speech production and comprehension, are common. Unlike Alzheimer's, memory is relatively preserved in the early stages. FTD has a more rapid progression compared to other forms of dementia.

5. Mixed Dementia:

• Characteristics: Mixed dementia refers to the coexistence of multiple types of dementia, typically Alzheimer's disease and vascular dementia.
• Progression: The progression of mixed dementia combines the features of the underlying types. Cognitive decline may be more pronounced, and symptoms can vary based on the proportion of each type present.

6. Other Rare Dementias:

• There are other less common types of dementia, such as Creutzfeldt-Jakob disease (CJD), Huntington's disease, and Wernicke-Korsakoff syndrome (often associated with chronic alcohol abuse). These types have specific underlying causes and distinct clinical presentations.

Each type of dementia presents its unique challenges and progression patterns. Understanding the differences is crucial for accurate diagnosis, effective management, and tailored care plans. Healthcare professionals, caregivers, and families must be knowledgeable about these variations to provide the best possible support and enhance the quality of life for individuals affected by dementia. Early diagnosis, appropriate interventions, and compassionate care play vital roles in improving the well-being of those living with dementia and their loved ones.

Hospice's Role in Dementia Care
