Public Health PriorityDEMENTIAWorld Health OrganizationIMPACT35.6 million with dementia

Nearly doubles every 20 years

Alzheimers in the USA will ALMOST TRIPLE BY 2050

World Alzheimer Report 2011. 1228 million of the worlds 35.6 million people with dementia have yet to receive a diagnosis

World Alzheimer Report 2011. 13A Quality Dementia Diagnosis Changes Everything

Annual dementia care costs $32,865 per person

With a quality dementia diagnosis annual dementia cost decreases to $5,000 per person

Improved health & quality of life even more cost-effectiveImpact of a Quality Dementia DiagnosisWorld Alzheimer Report 2011. 15

Earlier diagnosis allows people with dementia toplan ahead while they still have the capacity, receive timely practical information, advice and support

get access to available drug and non-drug therapies

participate in research for the benefit of future generations

World Alzheimer Report 2011. 167.7 million new cases yearly.New case of dementia every? A. 18 minutesB. 23 hoursC. 4 seconds D. 23 minutesE. 30 seconds


Worlds 18th largest economyDEMENTIA

de Vugt ME, Verhey F, 2013.If dementia care were a country, it would be the worlds 18th largest economy.18

Dementia Costs More Than 1% Gross Domestic Product Borson, S. et al., 2013.The worldwide costs of dementia exceeded 1% of global GDP in 2010, at US$604 billion. If dementia were a company, it would be the worlds largest by annual revenue exceeding Wal-Mart (US$414 billion) and Exxon Mobil (US$311 billion).19

RISKAgeFamily history and geneticsPsychiatric disordersCardiovascular disease related factorsHead traumaAlcohol, drugs & toxinsVasculitis, Endocrine & Infectious disorders Neoplastic & Respiratory disordersBrain lesions, normal pressure hydrocephalusFillit HM, et al., 2010. & Patterson C, et al., 2007. Age is the most potent risk factor. AD 40 years to 90 years for diagnosis. In familial AD onset is in the 30s is not unheard of. FTD typically with onset younger than 65.Family history and genetics young onset more often associated with strong family history with autosomal dominance. FTP are more likely to have family history. In AD mutations of the presenilin-1 gene predominate in patients who are less than 60. Occasionally families with late onset dementia occur.Gender men more likely to have vascular, dementia with Lewy bodies and women more likely to have AD. Gender influences behavior and hormonal levels which could influence dementia risk. Psychiatric disorders - In several studies depression precedes dementia. Psychosis visual hallucinations part of core criteria for lewy bodies and common in PD can precede dementia. Delusions notably paranoia common in AD. Impaired insight and judgment spectrum of symptoms in FTD and vascular. CV HTN, DM, smoking, hyperlipidemia increase risk of late life dementia.Educational attainment and physical activity level have been associated with dementia risk.Head trauma factor for late life dementia.Direct effects of alcohol on CNS can produce syndromes such as Wernicke encephalopathy (nystagmus, restricted EOM, ataxia) and Korsakoff syndrome (persistent executive and memory dysfunction). Medications have been associated with chronic cognitive impairment (corticosteroids, anticholinergic medications, benzodiazepines, psychiatric medications, antiepileptic's, etc.)Toxins like aluminum, mercury, bismuth, lead, pesticides, copper, and zinc. Vasculitis can cause dementia through ischemic damage.Thyroid, parathyroid, adrenal disorders are associated with chronic cognitive impairment. Diabetes may lead to cognitive dysfunction with or without CV events. 20Mild Cognitive ImpairmentNOT the result of normal agingForgetfulness is hallmark symptomSometimes called a transitional phase Conversion rate 2 - 15% per yearUp to 80% conversion at 6 years

Mayo Clinic: There are five stages associated with Alzheimer's disease: preclinical Alzheimer's disease, mild cognitive impairment, mild dementia due to Alzheimer's, moderate dementia due to Alzheimer's and severe dementia due to Alzheimer's. Dementia describes a group of symptoms affecting intellectual and social abilities severely enough to interfere with daily functioning.

Rate of progression through Alzheimer's stagesThe rate of progression for Alzheimer's disease varies widely. On average, people with Alzheimer's disease live eight to 10 years after diagnosis, but some survive as long as 25 years. Pneumonia is a common cause of death because impaired swallowing allows food or beverages to enter the lungs, where an infection can begin. Other common causes of death include complications from urinary tract infections and falls.

27Alzheimers DiseaseImpairment in memoryFunctional impairment social or vocationalAnd impairment in one other cognitive areaAgnosia - impaired ability recognize objects Aphasia - language disturbances in expressing, understanding Apraxia - inability to carry out motor activitiesAttentionExecutive functionVisuospatial ability

Other criteria: Progression is insidious and other diseases that could cause cognitive decline have been ruled out, diagnosis is primarily based on clinical judgment. Fillit HM, et al., 2010.28AD - Damage to plaque and neurofibrillary tangles, synapse loss, atrophy starts medial temporal lobe

A. Two thirds

32Vascular DementiaSecond most prevalent dementia 1/3

Also know as multi-infarct dementia

The brain has multiple vascular lesions in the cortex and subcortical areas, sometimes called small strokesMemory loss most common complaint

The cognitive changes that occur are directly related to the location of the lesions

Working memory more likely to be impaired more than delayed recall

Fillit HM, et al., 2010.33

Vascular DementiaCued recall recognition previously learned material generally intactExecutive dysfunction more commonly reported than in AD

Depression common

Over the years, three main ideas of hippocampal function have dominated the literature: inhibition, memory, and space.


37Frontotemporal Dementia

Parkinsons DementiaParkinsons affects the extrapyramidal systemUsually diagnosed 50-60sSubstantia nigra approximately 50% reduction neuronsMay develop in 20-40% Parkinsons patientsMotor symptoms precede dementia by at least 1 year

Depression occurs up to 50% of PDFillit HM, et al., 2010.39

Parkinsons DementiaIMPAIRMENTS: AttentionExecutive function Visuospatial functionInsidious onset, variable rates of progressionEpisodic memory deficits milder than in PDProblems more retrieval than encoding/storage

Fillit HM, et al., 2010.40Dementia with Lewy BodiesThe form of dementia that has both cognitive impairment with extrapyramidal signsDLB dangerous sensitivity to neuroleptic medicationsDecreased dopamine transporter binding Motor symptoms occur no more than a year before then onset of dementia and frequently after the dementia DLB Symptoms:fluctuating cognition, Parkinson-like symptoms and visual hallucinations, other symptoms may include REM sleep disorders, and frequent falls.Fillit HM, et al., 2010.Extrapyramidal syndrome (EPS) is due to the blockade of dopamine receptors in the basal ganglia, leading to Parkinson-like symptoms such as slow movement (bradykinesia), stiffness, and tremor.41Functional Assessment Staging (FAST)Stage 1 Normal adult. No functional decline. Stage 2 Normal older adult. Personal awareness of some functional decline. Stage 3 Early AD. Noticeable deficits in demanding job situations. Stage 4 Mild AD. Requires assistance in complicated tasks such as handling finances, planning parties, etc.

Stage 5 Moderate AD. Requires assistance in choosing proper attire. Stage 6 Moderately Severe AD. Requires assistance dressing, bathing, and toileting. Experiences urinary and fecal incontinence. Stage 7 Severe AD. Speech ability declines to about a half-dozen intelligible words. Progressive loss of the ability to walk, sit-up, smile, and hold head up.42What is Jills FAST STAGE?ADLs: Independent in eating & transferIADLs: Dependent in ALLGDS: 4/15, negativeLabs: not remarkableBrain Imaging: Diffuse atrophyPMH: HTN, DM II, CADPhysical Exam: ConfabulatesSLUMS 3/30

TREATMENTConsiderable variation in clinical practice regarding pharmacological treatment of dementiasBereczki D, Szatmri S, 2009. 46Dementia Key FindingsMost people with early stage dementia wish to be told of their diagnosis

Improving the likelihood of earlier diagnosis:medical practice-based educational programs, introduction of accessible dementia care services, promoting effective interaction in the health system

Early therapeutic interventions:improving cognitive function, treating depression, improving caregiver mood, delaying institutionalizationWorld Alzheimer Report 2011 47Tips cognitively impairedReduce environmental distractionsApproach from the front, make eye contact, address person by name, speak in calm voiceTo reduce sense of threat, talk first, then touchAvoid verbal testing or questioning beyond the persons abilityDo not argue or insist they accept your reality
