Abstract

As the estimated 5.4 million people in the U.S. with Alzheimer’s disease or a related dementia (ADRD) approach a predicted 16 million by 2050, careful diagnosis, treatments, and family care management become more critical than ever. While health providers educate patients and family caregivers about diagnosis and treatments for progressive dementia, important strategies that address the family’supcoming lifestyle changes in their lifestyle,job or home routines, driving safety, financial and legal matters, and linkage to important community and internet resources may not be covered. Not only are health and behavior changes of progressive dementia important to know for long-term care planning and management, but also understanding how different types of dementia impact different abilities over time is critical for timing and prioritizing steps for care planning and management over the long term.The varied decline and challenges of different progressive dementias mandates a strong role for the health provider and health team to guide the family over the long–term of clinical care. This article overviews briefly major categories of dementia (Mild Cognitive Impairment, Alzheimer’s disease, vascular dementia, frontotemporal dementias, and Parkinson disease with dementia as well as parkinsonisms such as Lewy body dementia, progressive supranuclear palsy,and corticobasal degeneration) and provides a tool, a Checklist on Family Matters,for the clinician to offer the patient and family caregiver(s) to plan for the long–term care management.

Introduction

The estimated 5.4 million people in the U.S. with Alzheimer’s disease or a related dementia (ADRD) receive more than 17.5 billion hours of care from about 15.4 million unpaid family and significant others; the unpaid care represents $216 billion [1]. By 2050 the numbers of people with ADRD are expected to reach 16 million; the current estimated $203 billion costs of direct care are predicted to reach $1.2 trillionin 2050 [1]. These anticipated increases of a dementia–tsunami amplify the silver–tsunami [2] threatening the U.S. socio–economic–healthcare infrastructure.

As used here,progressive dementia is the ongoing decline of a person’s memory and other mental abilities to the point of interfering with interactions and accomplishing daily tasks on the job or at home.Progressive dementiais most often diagnosed as Alzheimer’s disease(AD) thoughthere are more than 100 different progressive dementias including vascular dementias, frontotemporal dementias, and Parkinson disease with dementia as well as parkinsonisms(such asLewy body dementia, progressive supranuclear palsy,and corticobasal degeneration).

The Problem

Early medical evaluation, diagnosis, intervention, treatments, guiding families about planning ahead for long–term care managementare critical to reverse, stop, slow down, or manage treatable or progressive dementias [3]. After the comprehensive medical evaluation when the patient and family⁄significant other(s) learn of the clinical diagnosis of ADRD, they often feel overwhelmed, not only by the diagnosis, but also by their simultaneous anticipation of the impending encumbrances of futuredecline. Foreseeingthelongterm challenges of the disease, the familymay experience a familytsunami feeling at a complete loss about the next steps to take, especially for less commonly known progressive dementias, such as Lewy body dementia, frontotemporal dementias, or a parkinsonism. While physicians may recommend treatments, they typically do not cover important strategies to address upcoming related lifestyle changes in job or household routines, driving safety, or financial and legal matters.Often the patient or family is aware of changes from Alzheimer’s disease, but naive about the possible health and behavior changes of other progressive dementias or how to prepare for future changes in their lives. The health provider should educate the patient, when appropriate, and the family caregiver(s) about how the specific diagnosed dementia will impact different abilitiesand offer challenges over time, important to the family’s timing and prioritizing steps for long–term care planning and adaptations.

Addressing lifestyle issues early after the diagnosis allows the family time to:learn about long–term care planning and strategies, communication with members of the extended family,anticipating stress–reactions fromfuture lifestyle adjustments, and developing back–up plans to minimize the fallout from unexpected health or family crises.In families where the person with the diagnosisis the matriarch or patriarch carryingmost of the responsibility for the family finances, legal matters, running a family–owned business, or making household decisions, the other family members may be unaware of the numerous tasks whichshould be graduallytransferred to others. It may take time to identify which family members can help, are available, have goodcommunication and care skills, and which ones may not be as available, skilled, overwhelmed with health or personal problems, not reliable, or not trustworthy.

The health team (physician, nurse, social worker, therapists, etc.) should provide education about the diagnosed dementia,recommended medical treatments and care plan, and local as well as e–resources. The varied decline in different progressive dementias, [4] however, mandatesexpertise from the health providers. The following information briefly describes a clinical template for education and guidance for some different types of dementia: Mild Cognitive Impairment (which may not decline further to become a progressive dementia), Alzheimer’s disease, vascular dementia, frontotemporaldementias, and Parkinson disease with dementia as well as parkinsonisms (that is, Lewy body dementia, progressive supranuclear palsy,and corticobasal degeneration). An outline,Checklist on Family Matters, (see Figure 1.) keys on points for the health team to overview as they guide the patient and family caregiver (or significant other) to plan ahead.

Clinical Template: After the Diagnosis

Education, Treatment, Prioritizing, and Planning Ahead First, Education

A health care professional with special training and experience in progressive dementia should take time to explain the diagnosis resulting from the comprehensive medical evaluationand include three points:

In addition to answering questions from the patient and family, a health expertor health team should provide handouts, educational references, internet links, and referrals to local community resources that provide information, services, and support.

Second, medical treatment and healthy lifestyle recommendations

While the physician–patient–family caregiver discussion should cover the many treatments such as cholinergics, serotinergics, and neuroprotective medicines to improve or slow decline of memory and other cognitive functions, it is important to treat and stabilize existing chronic health conditions such as hormone imbalance or cardiovascular problems, and stop anticholinergics such as antihistamines. The health team should encourage the patient and family to pursue a lifestyle thatbenefits brain health such as:

Third, Prioritizing

The health team should encourage the patient and family⁄ significant other caregivers to think about priorities, values and interests. The patient should prioritize a Wish List and form plans to pursue wishesto: travel, visit family, join a new club, take a class, learn a new skill or refresh an old one, hold a reunion, etc. Independentor interdependent functioning to fulfill the Wishes List depend upon the patient’s level of health, cognitive and physical functioning, and resources. The person with greater cognitive declinewill be wise topartner with one or more loved onesor a trustworthy person to pursue the items on the Wish List.

Fourth, Planning Ahead (see Figure 1.CHECKLIST ON FAMILY MATTERS)

Soon after a diagnosis of a progressive dementia, because financial, legal, and other family matters may require detailed discussions and decisions, the health team should share a guide such as the Checklist on Family Matters to allow enough time for the patient and familyto deliberate and take action steps.The patient should identify preferences for diet, daily routine, and activitiesfor current as well asfuture reference when abilities change, i.e., when personal assistance is needed in–home orat a community facility and later end–of–life care. These preferences should be discussed, written down, and shared with the health provider and, as appropriate, trusted loved ones.

The points on the Checklist on Family Matters may take a few weeks or months to consider. After pondering on the points of the Checklist on Family Matters, convening a family meeting to review the points may clarify to relatives how to become involved with caregiving over time, such as helping with home repairs, cleaning tasks, hands–on care, and volunteering for back–up plans, such as for an unexpected family illness, caregiver hospitalization, or harshweatheremergencies.

Guidance for different dementias

The following sections on Mild Cognitive Impairment, Alzheimer’s Disease, Vascular Dementia, Frontotemporal Lobar Degeneration, andParkinson Disease with Dementia as well as Parkinsonisms (i.e., Lewy Body Dementia, Progressive Supranuclear Palsy,and Corticobasal Degeneration)suggest differentapproaches to guide the care planning steps.

When the Diagnosis is Mild Cognitive Impairment

Mild Cognitive Impairment(MCI)refers to a mild decline in one or two cognitive functions such as short–term memory, recall of words, or other thinking function such as planning and decisionmaking. However, the decline typically does not interfere in the ability to manage daily routines, job or household responsibilities, relationships, or driving skills, and thus, is considered to not bedementia. MCI function may stay at the same level over time, buteach year 10–15% of people with MCI who are 65 or older convert to early Alzheimer’s disease or a related dementia [10–11].

Most people with a diagnosis of MCI are self–sufficient and likely will benefit from:

To assist with leadership responsibilities, such as on the job, in a community group, or with the extended family, the person with MCI should appoint, identify, or elect a partner to train in the role of CoChair, assistant CEO, or future family matriarch⁄patriarchin order to share responsibilities with that “mentee” or for succession trainingas the next leader.

hed

Dementia of the Alzheimer’s Type (AD) refers to the person who has a decline in two or more cognitive functions such as short–term memory, recall of words, keeping up with bills or appointments, and problems making decisions [12,13]. The decline interferes in the person’s ability to manage relationships and daily routine tasks on the job or at home. Typically, the first decline occurs in short–term memory (forgetting appointments, details of an event, or location of items such as keys, eyeglasses, shoes, etc.). The second area of decline is usually in the recall of names or other specific words. The third area of decline may involve visuospatial skills (getting lost while driving), and⁄or apraxia (becoming more clumsy with learned hand skillssuch as when repairing or using appliances). Typically in early AD, mobility, such as gait and using stairs, is fine until much later in the course of decline.

The progressive decline of AD may be characterized as three stages: 1) the Forgetful Stage, 2) the Confusion Stage, and 3) the Severe Stage.As people with a diagnosis of AD progress from early stages to the severe stage of decline, they slowly shift from being self–sufficientto dependent. Meanwhile the health provider’s management of care adapts to the ever–increasing need for respite and stress reduction of the family caregiver.

While most people with a diagnosis of Early AD or the Forgetful Stage of ADcan function independently, the clinician should encourage the patient to bring at least one other trustworthy person (with normal memory and cognition) to the medical evaluation to offer a different perspective to supplement the patient’s self–report of functioning and to receive the care plan updates. The patient andcaregiver should benefit from:

When the DiagnosisisVascular Dementia (or Cardiovascular Dementia)

Cardiovascular dementia is considered the second most commonly occurring dementia in the U.S. (Lewy body dementia, which some researchers consider to be the second most common progressive dementia, is discussed later in the section on parkinsonisms.) In early decline the health provider, patient, and family caregiver should optimize and stabilize cardiac or blood circulation conditions, such as hypertension, high LDL or triglycerides, arteriosclerosis, atherosclerosis, diabetes, or strokes [14].

When the Diagnosis isFrontotemporal Dementia [15–17]

Frontotemporal Dementia, also calledFrontotemporal Lobar Degeneration (FTD)involves slow decline in the frontal and⁄or temporal lobes appearingin people 40 – 60 years of age. There may be limited insight about personal and cognitive changes, increased or decreased sleep.The three categories of FTD are:1) BehavioralChanges, 2) Language Changes, and 3) Movement Changes.

Early Behavioral Changes may involve: unsocial behavior such as rude or embarrassing remarks, inappropriate conduct such as anger outbursts in public; lack of emotional expression such as a neutral response that seems uncaring to someone else’s grief or pain;a problem with boundaries or limits such as hugging strangers,overeating, or insatiable cravings for sweets; or difficulty with choices.

Early LanguageChanges(including speech, comprehension, writing, or reading) may involvepaucity of speech (nonfluency) or being unable to: recall words, use correct words, understand speech or written words, read, or correctly pronounce words.

Early Movement Changes may involve being unable to move ones limbs correctly to walk, move facial muscles fully to express feelings, or do skilled movements such as use a key, phone, or zipper.

When the Diagnosis is Parkinson disease with Dementia or a Parkinsonism such as Lewy Body Dementia, ProgressiveSupranuclear Palsy, or Corticobasal Ganglionic Degeneration

Parkinson Disease with Dementia: Primarily a movement disorder, Parkinson disease features any combination of slowed movement and thinking,balance and gait difficulties, cogwheel rigidity (in muscles), resting tremor, tiny handwriting, decreased facial expression (masked facies), and depression; dopaminergic medicines provide significant benefit as do antidepressants, where indicated. Up to 80% of people with Parkinson disease will develop memory and cognitive disorders and they benefit from cholinergic medications [4].

Parkinsonisms: Many people with movement difficulties which resemble Parkinson disease have a parkinsonism, often called a “cousin of Parkinson disease”. These atypical disorders,for reasons not clearly understood, may benefit somewhat or not at all from dopaminergic medicines.In the following brief discussions of three parkinsonisms,Lewy Body Dementia, Progressive Supranuclear Palsy, and Corticobasal Ganglionic Degeneration, the discussion of Lewy Body Dementia is lengthier because it is considered the 2nd or 3rd most commonly occurring [4].

When the Diagnosisis Lewy Body Dementia [4,18,19] : Recent scientists have insisted that Lewy body dementia(LBD) is the second most commonly occurring slowly progressive dementia. The onset of LBD symptoms occurs in people in their 40s or 50s. Typically, the early symptoms of LBD include visual hallucinations, movement problems, periods of on–off physical or thinking functions, and sleep problems, explained further below:

Early symptoms:

  1. Visual hallucinations (less often auditory hallucinations).
  2. Movement difficulties such as stiffness, slowness,or clumsiness when moving such as when walking; difficultysitting in or rising from a chair, problems with balance; sometimes better movement and sometimes worse (or freezing up of) movement;lack of facial expression(masked facies).
  3. On–off mental function.
  4. REM–sleep (Rapid Eye Movement) disorder which may include kicking, arm swinging, and yellingas if acting out a dream. The patient may beunaware of the activity, often reported by the sleep–partner.

Later symptoms:

  1. Personality changes, i.e., social withdrawal, more irritable, more outgoingor withdrawn, or socially inappropriate
  2. Less interested in leisure activities
  3. Unwilling to do routine tasks
  4. Unwilling to do routine tasks
  5. Frequent stumbling or falling
  6. Much symptoms:

    1. Decline in short–term memory, word recall, and other cognitive functions
    2. More irritable, restless, and⁄orwithdrawn
    3. Frequent falls
    4. When the Diagnosis is Progressive Supranuclear Palsy (PSP) [4,18,20,21]

      An atypical progressive dementia, the parkinsonism, Progressive Supranuclear Palsy (PSP) usually appears in people above 50 years of age. [21] PSP prevalence has been estimated as 1 to 6 or more per 100,000 people [18,21]. The early key features of PSP are balance problems, gait difficulties, midline rigidity, and “doll’s eyes” (vertical palsy – difficulty with upgaze) [20,21]. Much later there is decline in memory, language, and other cognition [20,21].

      When the Diagnosis is Corticobasal Ganglionic Degeneration (CBG): [22]. Also an atypical progressive dementia, the parkinsonism, Corticobasal Ganglionic Degeneration (CBG)occurs in4 to 7 or more people per 100,000 [4,23]. The key feature of CBG is the asymmetry of movement difficulties, usually beginning with increased clumsiness or failure to control the fingers to perform skilled movements (apraxia)in one hand. The problem in one hand expands to the whole arm before affecting the same–side leg or the other hand. In some cases the hand seems to have its own will (alien hand) and respond to external stimulus rather than obey the will of its owner. Later swallowing and speech difficulties occur. Much later there may be decline in memory and other cognitive functions [22,24–27].

      After the Diagnosis ofParkinson disease with Dementia or a Parkinsonism such as Lewy Body Dementia, Progressive Supranuclear Palsy or Corticobasal Ganglionic Degeneration.

      Education: Should involve the clinician explaining to the patient and family caregiver⁄significant other the typical picture of initial slow decline in movement and then later decline in memory and other cognitive functions. It is important for the patient to function as fullyand as long as possible. Early on, physical therapy for balance, gait training, finger–hand exercise, and regular physical exercise are key. The patient and family need to compensate for the motor slowing by increasing their patience, allowing more time for physical activities, and allowing more time for the patient to think and respond during interactions. Later when swallowing becomes a problem, speech therapists can offer meal tips such avoiding dry foods (i.e., crackers, plain meat, chunks of fresh vegetables or fruits, etc.) and including wet, smooth foods such as stews, custard, and thickened beverages. Suggestions forfuture decline include patient–caregiver teamwork to help with personal care and other activities, memory tips,and maintaining familiar routines and ways to do tasks.

      The physician may do a one–time, brief trial of a Parkinson medicine (a dopaminergic medicine) to see if there is improved movement and thinking. A clear improvement in movement and thinking function may indicate a diagnosis of Parkinson disease (with or without memory or other cognitive problems). Partial improvement may indicate a parkinsonism. No improvement from the dopaminergic medicine strengthens the suspicion of parkinsonism.

      For Lewy body dementia education should include early coping strategies to address hallucinations, insomnia, and on⁄off times, forexample:

      1. People with Lewy body dementia usually realize and accept that theirvisual hallucinations are not real when others report not seeing them. Sometimes changes in the setting (removing dark or intimidating furnitureor covering mirrors and other reflective surfaces) or a distractionwill help.
      2. Early on, help from a physical therapist should address difficulties with balance and gait and design of an exercise routine; an occupational therapist should recommendways to assist movementstruggles and making the home and yard settings safe.
      3. Ways for family caregivers to ensure that the patient is paying attention and “tuning in” include: addressing the patient by name, making eye contact, repeating comments, speaking in a strong, pleasant voice, and asking for a simple answer to check alertness andcomprehension.

      Sleep changes may be problematic and may improve with sleep hygiene such as limiting caffeine later in the day, daytime exercise, relaxed pre–bedtime activities and massage, routine bedtime and awakening times, and no daytime naps.

      For PSP, the education should address problems with upgaze (vertical gaze palsy, often called doll’s eyes) and teaching the patient and caregiver the importance of compensating for the decrease in visual fields by increasing horizontal and vertical neck–turning for morecareful looking when walking; an occupational therapist can offer suggestions regarding decreasing fall and injury risks in home and other settings.

      Treatment: The physician can prescribe cholinergic and serotinergic medicines to benefit function. The physician should emphasize the importance of avoiding any antipsychotic medicine, especially to treat hallucinations or sleep problems associated with Lewy body dementia tosteer clear of paradoxical effects or worsening of dysfunctions. The physician should refer the patient for a physical therapy evaluation for early symptoms of movement and balance difficulties evident in a slower, stiffer, tipsy gait; physical therapy to aide movement, an exercise plan, decrease fall risks, and especially to identify appliances such as a simple cane, a quad–cane and later a cane with a sling seat or a walker. Other useful referrals in an occupational therapyto evaluate the home setting, and a sleep study to evaluate sleep architecture.The physician should recommend that the patient stop driving until passing a comprehensive driving test, which is more in–depth than a driving test at a Department of Motor Vehicles.

      A trial of a dopaminergic may help mobility; treating depression will help physical and cognitive functioning and contribute significantly to the quality of daily life.

      Prioritizing: Values, interests, and health goals should be a collaboration of the patient, the primary caregiver (family member or significant other), and the health provider. The patient should consider a Wish List of priorities to undertake in the 6 –12 months and another Wish List for later that accommodates ongoing decline in mobilityand safe activities for a person with balance and walking problems or using a cane or walker.The patient should continue their hobbies, relationships, safe physical activities, and daily brain exercise for as long as possible.

      Planning Ahead: The clinician should work with the family and offer a guide such as the Checklist on Family Matters to motivate the family to begin to plan for future health changes.The patient should indicate preferences to help them remain as active in tasks, personal care, hobbies and relationships for as long as possible. The patientand family should consider care preferences of the patient as decline occurs and should write down decisions for future reference.

      In the case of Lewy body dementia the cliniciancare plan should work with the family to deal first with visual hallucinations and mobility changes, next sleep changes, and later the memory and othercognitive changes, as they begin to surface.

      Conclusions

      After the clinical evaluation indicates a progressive dementia, the physician (and health team) should educate the patient and family about the condition, offer clear instructions about treatments, and additional information such as educational handouts, references, and community as well as internet resources to provide assistanceand support to the family over the long–term management of the health condition. Healthylifestyle changes such as good nutrition, drinking plenty of water every day, regular physical exercise, daily brain exercise, and reducing stress may improve cognition or slow further decline.

      Treating and stabilizing cardiovascular conditions may slow down the decline of vascular dementias. Recommending, as appropriate, cholinergics, neuroprotective medications, and antidepressants for progressive dementias such as Alzheimer’s disease, frontotemporaldegeneration and the parkinsonisms, should optimize function, delay decline in routine tasks and personal care, and enhance the quality of life for the patient and loved ones.Different progressive dementias require different care plan timing strategies, for example:
