    • Overview of PD
    • What is PD? History of PD Cathi A. Thomas, MS, RN, CNRN Department of Neurology Boston University Medical Center
    • What is Parkinson’s Disease (PD)? • PD is described as a chronic, progressive neurological condition. • Second most common neurodegenerative disease following Alzheimer‟s disease • PD is a “hypokinetic” movement disorder. • Movement Disorders are a group of conditions that cause abnormal movements usually “too much” or “too little”.
    • Parkinsonism• IDIOPATHIC PARKINSON’S DISEASE.……....85%• Neuroleptic-induced parkinsonism…………7% - 9%• Multiple system atrophies (MSA)……………….2.5%• Progressive supranuclear palsy (PSP) ………..1.5%• Vascular parkinson syndrome…………………….3%• MPTP, CO, Mn, recurrent head trauma………....rare• Postencephalitic parkinsonism……none since 1960s
    • Historical Perspectives• James Parkinson (1755-1824) published An Essay on the Shaking Palsy, 1817, London Described: • “Involuntary tremulous motion, with lessened muscular power, in parts not in action and even when supported; with a propensity to bend the trunk forwards, and to pass from a walking to a running pace: the senses and intellect being uninjured.”
    • History (cont’d)• 1960‟s - Discovery of the neurochemical basis of PD; use of L-dopa (precursor of dopamine) by Dr. George Cotzias• 1990-2000 “Decade of the Brain”• 21st Century - PD now considered a multi- system disorder
    • PD - Who is affected?• Recent study (Willis AW, et al, 2010) identified demographic and environmental factors of PD• Used extensive Medicare data set from over 10 years• 1.6% of U.S. population over 65 has a dx of PD
    • PD - Who is affected? (cont’d)• Approximately 130,000 people newly diagnosed each year in US• Men slightly more likely to have PD (1.55 male : 1 female ratio)• Caucasian men in the U.S. have up to double the rate of PD as compared to African Americans or Asians• Asian women have lowest rate of PD in the U.S. Reference: Willis AW, et al. Geographic and Ethnic Variation in Parkinson Disease:A Population-Based Study of US Medicare Beneficiaries. Neuroepidemiology 2010;34:143-151
    • PD - Who is affected? (cont’d)• Diagnosis typically occurs in the 5th and 6th decade of life (average age 63)• 5-10% of people have symptoms < 45
    • • Projected number of people with Parkinson‟s disease in the most populous nations will double by 2030- 4.3 million to 9.5 million worldwide.E.R. Dorsey et al, Neurology 2007;68:384-386
    • Economic Burden• Staggering Costs • The combined direct and indirect cost of PD including treatment, social security payments, and lost income is estimated at 25 billion in the US • Medication costs average $2,500 annually • Surgery costs average $100,000 (PDF Fact Sheet, 2007) • 2-7% of individuals in long-term care settings have a diagnosis of PD (Caring for the Ages - AMDA, 2003)
    • Introduction to the Roleof the Nurse in PD Care Cathi A. Thomas, MS, RN, CNRN Department of Neurology Boston University Medical Center
    • Delivering Care• The delivery of quality care to a patient/family living with Parkinson‟s Disease is complex and requires multiple disciplines working collaboratively to reach the best possible outcome• Quality Care is supported by care that is patient-centered, evidence based, and delivered by interdisciplinary teams• The nurse is a core member of the interdisciplinary team. Hickey, J., The Clinical Practice of Neurological &Neurosurgical Nursing, 6th edition, 2009 Wolters Kluwer Health, Philidelphia,PA.
    • • Nurses play an important role in care delivery across the continuum from diagnosis to end of life• Nurses encounter PD patients in many clinical settings• Increased utilization of nurses as disease progresses
    • Nurse Specialists in PD (U.S.)• Work in Movement Disorder Centers• Neurology Practices with large PD populations• Neurosurgical Practices with DBS Programs• Information and Referral Centers funded by lay organizations including APDA, and NPF• VA PADRECC Centers
    • These Nurses function as:• Nurse Practitioners• Clinical Nurse Specialists• Nurse Clinicians• DBS Nurses• Research Nurses• Coordinators supporting the Community at large (National organizations; APDA/NPF)• And more
    • “Frequent-Encounter” Nurses• Long Term Care Nurses (AMDA 5-10%)• Rehabilitation Nurses• Home Care Nurses (VNA, Parish Nurse, etc.)• Adult Day Health / Assisted Living Nurses• Geriatric Treatment Program Nurses• And more
    • “Chance-Encounter” Nurses• Nurses in Acute Care Settings (ER‟s, medical- surgical areas, orthopedic units, critical care units, psychiatric units, perioperative settings)• In the neighborhood….
    • Clinical Care• Assess signs and symptoms of an individual’s disease process and response to treatment over time (i.e. medication, bowel, bladder…)• Assess impact of these human responses on an individual‟s quality of life• Provide patient/family focused care• Assess patient/family coping strategies, define un- met needs, and provide support in accessing resources
    • Clinical Care (cont’d)• Provide patient/family education *medication*• Provide ongoing assessment and support to patients in between visits via telephone/e-mail• Implement center protocols to increase communication between patient/family and other disciplines (telephone triage, diary training)• Develop programs that enhance the delivery of care (day evaluation program)
    • Education and Support• Patient/family education• Healthcare professionals• Community at large
    • Patient/Family Education and Support• Disease process, targets of therapy, medication management, DBS, self management of activities of daily living, safe mobility, coping strategies• Development of educational programs and symposia for patients/families in a practice or community (newly diagnosed, young onset, family caregivers)
    • Research• Nurses participate in PD research in a number of ways: • Investigator exploring models of care evidence-based practice • Consultant to other disciplines conducting research “providing the nursing perspective” • Clinical Trial Coordinator (Parkinson Study Group, NET PD, Industry trials)
    • Thank You To All Of The Nurses Who Have Supported Me Along The Way. A Special Thanks To The Nurses Who Have Joined Us Today. Happy Neuroscience Nurses Week!
    • Overview of Pathogenesisand Epidemiology of PD Susan Heath, MSN, RN Movement Disorders CNS San Francisco VAParkinson‟s Disease Research, Education and Clinical Center (PADRECC)
    • Objectives• Describe current evidence and theory of the pathogenesis of idiopathic Parkinson‟s Disease.• Discuss genetic and environmental evidence and theory into the cause/s of Parkinson‟s Disease.
    • Pathogenesis: What happens to the brain in PD?
    • Parkinson’s as we were taught Olanow, C. W. et al. Neurology 2009;72:S1-S136
    • Lewy Bodies• Alpha –Synuclein are proteins found inside Lewy Bodiesand these are the pathologic hallmark for PD.• Unknown if LB‟s are the toxin to the cells causing PD?• Or are LB‟s the end result or „trash can‟ response in dying cells?
    • Parkinson’s as we think about it now Olanow, C. W. et al. Neurology 2009; 72:S1-S136
    • Multiple Sites ofNeurodegeneration in PD•Dopamine (DA)– red•Norepinephrine – green(May precede loss of DA: Associated withbrain functions such as: sleep, memory,learning and mood)•Serotonin – orange(May precede loss of DA: Associated withmood, anxiety, appetite, GI function and pain)•Acetylcholine – blue(Associated with memory and learning) Lang & Lozano (1998)
    • Theoretical Causes of Idiopathic PD • Idiopathic PD is 90-95% „sporadic‟ and only 5% familial. • Etiology of sporadic form of PD is unknown. • Several single gene mutations are identified in familial PD but only a minority have a clear familial pedigree • More common in 1st degree relatives by 2-3 fold • PD twin study showed no sig. concordance of PD except if onset before age 50. • Thus young onset PD is more genetically determined.
    • Genetic Causes of PD =Parkinson’s genes have given clues to the multiple paths to cell death:• Mitochondrial and oxidative stress• Protein degradation malfunction (trafficking)
    • Parkinson’s Disease & the Pesticide Link Environmental toxins (fungicides, herbicides and pesticides) are actively being investigated From: Web Ross MD Slides used with permission
    • • In a recent review, over 24 of 31 case-control studieshave shown an association of PD and pesticides.• PD risk is 1.6 to 7 times higher in pesticide exposed• The higher the exposure the greater the risk BUT • Broad • chemical • • • categories • • • Few specific agents identified Brown et al, 2006 From: Web Ross MD Slides used with permission
    • Summary: Pesticide - PD Link• Association does not prove „cause and effect‟ and the evidence that pesticides cause PD is still not definitive.• National Academy of Sciences Institute of Medicine determined that “there is limited or suggestive evidence of an association between exposure to the compounds of interest and PD”
    • Summary: What we know about the Pathogenesis of PD• Causes of PD remain elusive. (Tanner, 2010)• PD is more complex, gone is the simple notion that PD is a simple lack of dopamine.• Sporadic PD is diagnosed after the alpha-synuclein pathology has reached an advanced stage. (Braak et al, 2003)• Genetic mutations may contribute to one‟s susceptibility.• Most cases of sporadic PD are thought to be caused by an interplay of environment and genetics.
    • “The Parkinson Umbrella”Importance of Differential Diagnosis Gwyn M. Vernon, MSN, CRNP University of PA Parkinson‟s Disease and Movement Disorder Center and School of Nursing
    • Disclosures• Speaker‟s bureau • Ipsen • Teva • Medtronics
    • Objectives• Briefly, identify how the diagnosis of PD is established• Compare and contrast conditions and considerations in the differential diagnosis, ie. secondary parkinsonism and atypical parkinsonian syndromes
    • PD can be misdiagnosed40353025201510 5 0 Clinically Autopsies
    • How is PD diagnosed?• Prodrome phase • Depression, anxiety, non-specific cognitive changes, chronic constipation• Initial clues may be non-motor • Pain/sensory complaints, urinary symptoms, lethargy, visual symptoms
    • Non-Motor Symptoms (NMS) at initial presentation60%50%40% Pain Urinary30% Depression Cognitive20% Lethary10%0%
    • Delayed referral with non-motor symptom presentation
    • THE DIFFERENTIAL DIAGNOSIS: PARKINSON’S AND “Parkinsonisms”• Idiopathic Parkinson‟s disease• Secondary Parkinsonism• Atypical Parkinsonism
    • DIAGNOSIS OF PD: Motor Characteristics of IPD• Two of the following: • Rest tremor, cogwheel rigidity, bradykinesia• Asymmetric presentation• Robust response to levodopa
    • Additional Differential Diagnostic Considerations• Secondary causes ruled out • Often treatable or reversible• Atypical parkinsonian features not present early • Neurodegenerative, progressive
    • Secondary “Parkinsonism”• Metabolic (Wilson‟s disease)• Vascular lesions (Multi-infarct states)• Structural lesions (Hydrocephalus)• Drug induced
    • Drug-Induced Parkinsonism• Typical neuroleptics • Such as haloperidol (Haldol)• Metaclopramide (Reglan)• Prochlorperazine (Compazine)• Promethazine (Phenergan)• Atypical neuroleptics • Risperidone (Risperdal), olanzapine (Zyprexa)
    • Atypical Parkinsonism or“Parkinson-plus” syndromes• Neurodegenerative disorders• May mimic PD early on• Progressive; treatments limited
    • Common Atypical Parkinsonisms: Approximately 15 % of presenting “PD” cases• Corticobasal degeneration• Dementia with Lewy bodies• Autopsies commonly show • Multiple system atrophy • Progressive supranuclear palsy • Alzheimer‟s pathology
    • American Academy of NeurologyPractice Guideline • Symmetry of signs and (2006) symptoms • Lack of tremor • Characteristics supportive of • Poor response to other levodopa parkinsonian syndromes • Falls early in course • Dysautonomia early • Rapid progression
    • Corticobasal Degeneration• Parkinsonism; +/- tremor, bradykinesia• +/- dystonia, myoclonus• Pronounced asymmetry• “Alien limb”, apraxia• Speech and sensory abnormalities• As name implies, degeneration of multiple cortical areas, especially frontal-parietal and basal ganglia; cause unknown, possible abnormality of “tau” protein
    • Dementia with Lewy Bodies (DLB)• Parkinsonism – bradykinesia and rigidity• Concurrent cognitive decline with • FLUCTUATING ALERTNESS AND ATTENTION • VISUAL HALLUCINATIONS Multisystem accumulation of abnormal protein deposits (Lewy bodies) in brain stem, basal ganglia and cerebral cortex………
    • Multiple System Atrophy• Shy-Drager • Autonomic degeneration• Striatal-nigral • MSA – P degeneration• Olivopontocerebellar • MSA -C atrophy
    • Multiple System Atrophy• Autonomic and Urinary Dysfunction • Orthostasis > 30 mmHg systolic or > 15 mmHg diastolic, or • Urinary incontinence, or • Both• Parkinsonism (MSA-P) • Bradykinesia plus one of rigidity, tremor or postural instability• Cerebellar (MSA-C) • Gait ataxia, plus one of : dysarthria, limb ataxia or sustained gaze evoked nystagmus
    • Progressive Supranuclear Palsy (PSP)• Parkinsonism: Bradykinesia, rigidity• Severe, early imbalance and falling• Slurred speech, dysphagia• Myoclonus• *Inability to gaze downward• “A tauopathy” characterized by abnormal accumulations of tau protein in cerebral cortex especially frontal areas, basal ganglia, cerebellum and spinal cord
    • Alzheimer’s disease with motor features• May appear to have severe bradykinesia• May have apraxia, visuospatial issues• Probably have:• Severe psychomotor slowing• Major depression (22.5-54.4%)
    • Diagnosis of Parkinson’s disease• Difficult; delayed; often misdiagnosed• Based on history and clinical findings; no laboratory testing
    • Parkinson’s vs. Parkinsonism Common differentials to consider• Idiopathic, typical Parkinson‟s disease• Secondary parkinsonism • Metabolic, Vascular, Structural, drug induced• Atypical parkinsonisms • Corticobasal degeneration, Dementia with Lewy bodies, MSA, PSP, Alzheimer‟s pathology
    • Differential Diagnosis Resources• Locate a specialist: • Parkinson’s Disease Foundation national hotline 800-457-6676; or “ask the expert” at www.pdf.org • National Parkinson Foundation • www.parkinson.org; click on “find resources” • American Parkinson Disease Association • www.apdaparkinson.org; click I and R centers
    • A correct diagnosis Leads to improved patient careLessens unnecessary interventions Gives patient and family confidence and support

    • Theoretical Models and Nursing Science• A theoretical framework allows for the structure of scientific inquiry, the framing of research questions, and the explication of relationships among important variables and outcomes.• Few theoretical models have been proposed to guide care for patients with PD and their family.
    • The Demographic Imperative: U.S. Projections• People age 65 and over is projected to increase from 39 million in 2010 to 69 million in 2030.• The 85 and older population is expected to more than triple, from 5.4 million to 19 million between 2008 and 2050..• The aging of the population will increase the annual number of deaths by over 70%, from 2.3 million in 1995 to 4.0 million in 2050.

    • Why Palliative Care? Questions• What do persons with Parkinson‟s disease say they want from our healthcare system?• What is the impact of Parkinson‟s disease on families? Answer• Palliative care promotes concordance with patient and family wishes
    • What is Palliative Care?“Palliative care is interdisciplinary care focused on the relief of suffering andachievement of the best quality of life for patients and their family caregivers” (Morrison and Meier, 2003)
    • WHO Definition of Palliative Care“An approach which improves the quality of life of the patient and their family‟s facing life-threatening illness, through the prevention, assessment, and treatment of pain and other physical, psychosocial and spiritual problems” (World Health Organization 2002)
    • Palliative Care is Family Care Who is the family?“Family is anyone who shows up when illness strikes and stays on to help” Carole Levine, 2003
    • Goal of Palliative Care• Provides relief from pain and other distressing symptoms• Affirms life and regards dying as a normal process• Neither hastens or postpone death• Integrates psychological and spiritual aspects of patient care• Offers support to families• Enhances Quality of Life WHO 2003
    • Conclusion• The Parkinson‟s Disease Model of Care• Presented the Parkinson‟s Disease Model of Care• Reviewed U.S. aging demographics• Defined palliative care as a philosophy of care
