Alzheimer s disease

Alzheimer’s Disease

A progressive degenerative and fatal brain disease that causes memory loss and problems with thinking and behavior severe enough to affect work, lifelong hobbies and/or social life functioning.

Overall, it affects quality of life and independence

7th Leading Cause of Death in USA

Accounts for >71,000 deaths per year

How is ad diagnosed practical procedures

How is AD diagnosed?Practical Procedures

  • History and Physical Examination

  • Assessment of memory and thinking

  • Blood tests and other laboratory studies to rule out systemic disorders

  • MRI to rule out brain lesions and sometimes PET

7

7


Why isn t there a simple test

Why Isn’t There a Simple Test?

  • No blood marker identified (lots of complicated screens proposed)

  • No consistent appearance on a neuroimaging test

  • Normal people have some AD changes

  • Too many false negatives and false positives

8

8


Can we prevent ad

Can we prevent AD?

  • No known effective measure

  • Studies cannot tell the difference between prevention and delay

  • Reducing mid-life cardiovascular risk factors is the leading hypothesis

9

What causes ad

What causes AD?

  • Plaques and tangles?

  • Loss of reserve?

  • Biochemistry of aging?

  • Weak genetic background?

  • Chronic inflammation?

  • All of the above?


Current therapies

Current Therapies

  • Cholinesterase Inhibitors (donepezil/Aricept; rivastigmine/Exelon; galantamine/Reminyl)

  • NMDA Receptor Antagonist (memantine/Namenda)

  • Anti-oxidant Vitamins? (Vitamin E 1000 IU; Vitamin C 1000 mg)

  • Medications for Behavioral and Psychological Symptoms of Dementia

Principles of management for behavioral and psychologic symptoms

Principles of Management for Behavioral and Psychologic Symptoms

  • Anti-dementia drugs reduce BPSD

  • An analysis must be done to look for avoidable triggers

  • Some behaviors may need medications eg antidepressants, antipsychotics

  • The risk/benefit ratio of antipsychotic meds is controversial

  • Sleep disturbance and anxiety should usually not be treated with medications

Alzheimer s disease a terminal illness

Alzheimer’s Disease:A Terminal Illness

Terminal illness is a medical term popularized in the 20th century to describe an active and malignantdisease that cannot be cured or adequately treated and that is reasonably expected to result in the death of the patient. It indicates a disease which will end the life of the sufferer.

Alzheimer’s Disease Course:

Prolonged and progressive disability

No preventive treatment

No curative treatment

Multiple other comorbidities

Retrogenesis

www.wikepedia.org


Alzheimer s disease a terminal illness1

Alzheimer’s Disease:A Terminal Illness

Retrogenesis

The process by which degenerative mechanisms reverse the order of acquisition in normal development, especially as exhibited by Alzheimer’s Patients.

Alzheimer s disease a terminal illness2

Alzheimer’s DiseaseA Terminal Illness

Weight Loss in Alzheimer’s Dementia:

Failure of body weight regulation

Higher resting energy expenditure

Hypermetabolism/Increased energy expenditure

Difficulties in providing sufficient calories

Neural control mechanisms lost

Multifactorial: stage of the disease, living situation, type of dementia

The clinical course of advanced dementia mitchell et al nejm 361 16 oct 15 2009

The Clinical Course of Advanced DementiaMitchell et al, NEJM 361:16, Oct 15, 2009

Prospective study of 323 nursing facility residents with advanced dementia

( CPS 5 or 6, Stage VII) and health care proxies followed for 18 mths.

Mean age 85.3, 85.4% women, 89.5% white (10.2% black)

54.8% died within 18 months, Probability of death within 6 mths was 24.7%

Probability of pneumonia 41.1%, febrile episode 52.6%, eating problem 85.8%

***If had one of these had a 6 month mortality rate of about 40%***

In last 3 months of life over 40% underwent burdensome txments

Proxies who had an understanding of poor prognosis and clinical complications expected in advanced dementia were less likely to request burdensome txments

Artificial feeding legal cases

Artificial Feeding: Legal Cases

  • Nejdl-Barber Case: 1983

    • California, Murder charges

    • Withdrew IV nutrition & hydration

    • “Brain Dead”?

    • Appropriate permission

    • Charges dropped

21

Artificial feeding legal cases1

Artificial Feeding: Legal Cases

  • Nejdl-Barber Case: 1983 (cont’d)

    ***Medical procedures to provide nutrition/hydration are more similar to other medical procedures than to typical human ways of providing nutrition and hydration. Their benefits and burdens ought to be evaluated in the same manner as other medical procedures***

22

Artificial feeding legal cases2

Artificial Feeding: Legal Cases

  • Claire Conroy Case: 1985

    • New Jersey

    • Removal of Nasogastric Tube

    • Severe End Stage Dementia

    • Incompetent but conscious patient

    • Lower Court – Removal = killing

    • Higher Court – Autonomy Issue

23

23


Artificial feeding legal cases3

Artificial Feeding: Legal Cases

  • Claire Conroy Case: 1985 (cont’d)

    • First time a state supreme court ruled that artificial feeding like other txments, may be withheld from an incompetent patient if it is burdensome and contrary to the patients’ interests and values

    • Also stated that certain patients in nursing homes may refuse medical txment, even at the risk of death

24

24


Artificial feeding

Artificial Feeding

  • AMA Council of Judicial and Ethical Affairs (1986)

    • “Artificially supplied nutrition and hydration are medical treatments to be considered in the same light as other technological procedures” ( Informed Consent needed)

    • In certain circumstances, life-prolonging medical treatment including “medication and artificially or technologically applied respiration, nutrition or hydration” may be withheld or terminated

Australian ruling on tube feeding

Australian Ruling on Tube Feeding

Case of Gardner; re BWV (2003)

Withdrawal of life-sustaining treatment from incompetent patients as governed by the Victorian Medical Treatment Act 1988

Justice Morris determined that the Public Advocate had the power under the Act to refuse further nutrition and hydration administered via PEG to a 69 year old woman in advanced stages of dementia

Court found that artificial nutrition and hydration constitutes medical treatment. It is subject to the same criteria of clinical appropriateness and consent as any other medical treatment, and is NOT a required sustenance measure in palliative care.

Tube feeding alzheimer s association ethics advisory committee

Tube Feeding: Alzheimer’s Association Ethics Advisory Committee

“All efforts at life extension in the advanced stage of Alzheimer’s creates burdens and avoidable suffering for patients who could otherwise live out the remainder of their lives in greater comfort and peace”

Cardiopulmonary resuscitation, dialysis, tube feeding, and all other invasive technologies should be avoided

Tube feeding amda cpg

Tube Feeding: AMDA CPG

  • Tube feeding is appropriate when

    • Benefits are not outweighed by risks

    • Choice is consistent with the known values and preferences of patient and family

  • In end stage dementia, tube feeding has been show to have little or not effect on the clinical course or outcome

Feeding tube data

Feeding Tube Data

  • PEG introduced in 1980

  • > 216,000 feeding tubes placed in 2000

  • Dementia patients account for 30% feeding tube placements

  • Long Term complication rate 32-70%

  • AGA Guidelines:

    • Patient cannot or will not eat

    • Gut is functional

    • Patient can tolerate the placement

Tube feeding dads quality matters http mqa dhs state tx us qmweb tube feeding htm

Tube Feeding: DADS Quality Mattershttp://mqa.dhs.state.tx.us/qmweb/TubeFeeding.htm

  • Tube feeding will only be used when it benefits the resident

  • Decision for tube feeding must address Risks/Benefits/Burdens

  • Only consider if it is likely to benefit the overall clinical status and it is consistent with patient’s values and goals of care

  • Use of tube feedings in residents with Advanced Dementia has not been shown to be superior to careful hand feeding

38


Discussion

Discussion

  • Feeding tube practice varies among facilities

  • Higher incidence of feeding tubes in for-profit nursing facilities

    • Cost saving measure

    • Higher per diem rates for tube fed residents

  • Advanced Directives extremely important

  • Role of race/ethnicity in End of Life Decision Making

  • Urban Nursing Facilities/Tertiary Care Hospitals

  • NP/PA knowledgable about LTC setting

    Mitchell, et al JAMA July 2, 2003 – Vol 290, No 1

39

39


Tube feeding eol care

Tube feeding & EOL CARE

  • The role of the care team is to help decision-makers understand the benefits, burdens and alternatives to tube feeding so they can make an informed decision, that considers the stage of illness and prognosis, and is consistent with the patient’s values and their goals of therapy.

40


Reframing the discussion comfort feeding only cfo

Reframing the Discussion:Comfort Feeding Only - CFO

Comfort in CFO refers to the stopping point in feeding, emphasizing that the patients will be fed as long as it is not distressing

Comfort refers to the Goals of the Feedings: Maintain nutrition through careful hand feeding

CFO allows for continued interaction with the resident

Places focus on what we ARE doing, rather than what we will NOT do (No ANH)

Dying With Advanced Dementia in the Nursing HomeMitchell et al, ARCH INT MED Vol 164, Feb 9,2004

Conclusions:

Those with Advanced Dementia who die in nursing facilities are NOT recognized as having a terminal condition

Those with Advanced Dementia who die in nursing facilities do NOT receive care that promotes palliation and comfort at End of Life

Many with Advanced Dementia did NOT have Advance Directives limiting aggressive care and received uncomfortable interventions before death

Hospitalized Patients with Advanced DementiaMeier et al. ARCH INT MED, Vol 161, Feb 26, 2001

1994-97 recruited patients admitted to Mount Sinai Hospital

- admitted for an acute illness and advanced dementia (≥ Stage 6d)

-randomized to Palliative Care Consult vs Usual Care

-99 subjects, median age 84, 81% female, 39% black, 36% white, 22% Hispanic, 29% from home and 70% from nursing home, 15% with Advanced Directives, DNR in 57.6%

-Feeding tubes:

17% on admission, 80% without at admission

62% of those without tubes at admission had PEGs placed

-Median survival – 6 mths.- No survival advantage with or without PEG placement

-More likely to receive PEG if African American and lived in NF

Appropriate use of nutrition and hydration

Appropriate Use of Nutrition and Hydration

  • To determine frequency of symptoms of hunger/thirst in terminally ill patients

  • To determine if these symptoms could be palliated without forced feeding/hydration or parenteral alimentation

    McCann et al, JAMA. Oct 26,1994. 272(16)

45

45


Appropriate use of nutrition hydration

Appropriate Use of Nutrition/Hydration

  • Prospective study – 32 patients

  • Mentally aware, competent patients

  • Terminally ill

  • Sxs recorded: hunger, thirst, dry mouth

  • Txs recorded: Types of food/fluids to relieve sxs

    RESULTS:

    Majority without hunger or thirst

    In those with sxs of hunger, thirst and/or dry mouth; sxs alleviated with small amounts of food, fluids, ice chips, lubrication to lips

Artificial nutrition and hydration issues final thoughts

Artificial Nutrition and Hydration Issues – Final thoughts

  • Difficult to discuss -Food, water are symbols of caring/ doing something

  • High tech association/ Enamored with tech

  • In reality: More or less care? Prolong dying? Prolong suffering? No survival improvement.

  • Appreciate cultural/religious background

  • Advanced Care Planning important(For each 10%  in # of DNRs, 4.5%  in Feeding Tube placement requests)

  • Recognize that Dementia is a Terminal Disease

  • Focus on patient comfort

  • Education about ANH

  • Comprehensive Approach to Transitions of Care (Team)

  • Need for Prospective RCT

  •  to Medically Administered Nutrition and Hydration or Comfort Feeding Only
