What is Dementia?• A terminal, progressive, chronic illness resulting from biological changes in the brain
• A “collection of symptoms” related to cognitive decline. Can include cognitive, behavioral, communicative & psychological symptoms
• 2nd most commonly reported symptom in geriatrics
• Alzheimer’s Disease is the most common type
• Note: Some causes of cognitive decline are reversible and not truly dementia

Dementia Types and Symptoms
Multidisciplinary Dementia Management
Early diagnosis by a multidisciplinary team improves outcomes and quality of life
Goals of care:o Early diagnosis
o Detecting and treating / compensating for communication, swallowing and cognitive problems
o Providing information and long-term support to caregivers
o Optimizing health, independence, safety, well-being
Medical Speech-Language Pathologists
• Minimum of a Master’s Degree + Clinical Fellowship
• Specialize in evaluation and treatment of speech, language, cognitive-communication, voice and swallowing
• Usually specialize in a certain population, setting or disorders – often cross trained in the medical setting
• Work in multiple settings, treat patients across the lifespan
• Serve as an integral member of many interdisciplinary teams – particularly related to dementia care

Key Language Impairments in Early Stages of Dementia
Impact of Communication Impairments
● Avoiding social situations● Increase in problem behaviors● Increased stress on the
caregivers ● Compromised safety
and well-being● Loss of independence
● Word finding difficulties● Difficulty telling a cohesive
story or communicating wants and needs
● Trouble understanding lengthy and complex information
● Difficulty participating in conversations
may lead to..
Cognitive – Communication Deficits
Seen commonly in older adults, usually associated with stroke, brain injury, neurodegenerative diseases etc.
Often irreversible in older adults with dementia
Deficits include: attention, orientation, memory, executive function, judgment, problem solving, reasoning, sequencing, thought organization

Objective Cognitive Assessments
MOCA SLUMS
Overview of Assessment in Individuals with Dementia
Assessment typically includes:
• Relevant case history, including medical status, education, occupation, and socioeconomic, cultural, and linguistic background;
• Review of auditory, visual, motor, cognitive, and emotional function;• Co-morbid deficits that impact communication / cognition • Patient and family reports of goals, preferences, as well as concerns;• Standardized and nonstandardized tests selected
with consideration for ecological and cultural validity;• Contextual factors that serve as barriers / facilitators • Follow-up services / referrals to optimize cognitive-communication
function, ensure appropriate intervention and offer support
• Early diagnosis is key to avoid complications and slow down progression
• A complete clinical evaluation should help you identify underlying impairments and need for SLP services
• Ask these three critical questions: • Can the patient consume adequate food, liquid, medication by mouth?• Is the patient safe in their current environment? • Can the patient communicate basic wants and needs?

Dementia Staging: Global Deterioration Scale
Developed by Dr. Barry Reisberg
Overview of the stages of cognitive function for those suffering from a primary degenerative dementia
7 stages:(No cognitive decline – Severe Dementia)Stages 1-3 are pre-dementia stagesStages 4-7 are the dementia stages
Beginning in stage 5, an individual can no longer survive without assistance.
Dementia: Functional Assessment• Go beyond traditional assessments and conduct more functional measures to
determine the individual’s strengths and weaknesses
• Incorporate personal goals leading to greater treatment success
• Goals must be SMART
• Prior level of functioning should warrant goal being addressed
• Need for each goal should be well-documented
• Be aware of test length and level of difficulty
• ASSESSMENT IN PWD IS AN ONGOING PROCESS
• When designing a care plan for maximizing function, refer to the following (Bayles & Tomoeda):o Strengthen the processes that have the potential to improveo Reduce demands on impaired cognitive systemso Increase reliance on spared cognitive systemso Provide stimuli that evoke positive memory, action, and emotion
• SLPs have an ethical responsibility to provide appropriate services that will benefit the individual and maximize cognitive-communication functioning at all stages of the disease process.
Dementia: Treatment Guidelines
Evidence-Based Interventions
Direct Interventions:• Sensory stimulation • Spaced Retrieval Training • Errorless learning methods • Montessori-based programming• Reminiscence therapy• Validation therapy
Indirect Interventions:• Caregiver education and training• Environmental modifications• Use of external aids and supports
Top Treatment Takeaways and Considerations
• Many factors to consider during assessment, developing care plan and providing treatment
• Both rehabilitative and facilitative services are appropriate for adults with dementia – to improve safety, function, and quality of life across all stages of severity.
• Achieving buy-in from the family / caregivers is critical in the carryover of treatment goals.
• Make yourself a common part of the interdisciplinary team - to keep updated on patient progress & to explain role, goals andtreatment to staff.
• Documentation should clearly and objectively specify how our skilled therapy services are helping to improve function in the specific domain that was assessed.
• Treatment must be individualized and patient-specific. One size does not fit all!
SWALLOWING IMPAIRMENTS (DYSPHAGIA)
What is DYSPHAGIA?
The word dysphagia is derived from the Greek words phagia(to eat) and dys (with difficulty).
It specifically refers to the sensation of food being hindered in its normal passage from the mouth to the stomach.
Dysphagia = any impairment in normal swallow function
Signs and Symptoms of Dysphagia
• Difficulty chewing • Pocketing (food remaining in the oral cavities)• Nasal regurgitation of food / liquids• Frequent throat clearing at meals• Coughing / choking at meals • Wet / gurgly voice quality• Multiple swallows per bolus • Globus sensation • Food “stuck” / “lump” in throat • Undesired weight loss• Fatigue when eating / drinking• Inability to manage secretions • Effortful chewing / swallowing
• Prevalence of dysphagia in individuals with dementia is between 13% and 57% (Alagiakrishnan, Bhanji, and Kurian, 2013)
• 45% of institutionalized elderly present with the dual diagnosis (Easterling and Robbins, 2008)
• Higher incidence of oropharyngeal swallowing abnormalities, including silent aspiration, more prevalent in patients with Alzheimer's disease than in normal elderly individuals (Horner et al, 1994)
• Prevalence of dysphagia in severe Alzheimer’s disease has been estimated between 84% to 93% (Affoo, Foley et al. 2013)
• Different clinical presentations of dementia will result in different swallowing or feeding impairments (Alagiakrishnan et al, 2013)
Dysphagia in Persons with Dementia (PWD)
Alagiakrishnan, K., Bhanji, R. A., & Kurian, M. (2013). Evaluation and management of oropharyngeal dysphagia in different types of dementia: a systematic review. Archives of gerontology and geriatrics, 56(1), 1-9.
Including “typical” dysphagia symptoms, PWD may also develop:
o Food agnosia resulting in difficulty distinguishing food from non-food items (Wasson, 2001)
o Perceptual and spatial deficits resulting in difficulties recognizing food and utensils (Brouwers, 1984)
o Apraxia resulting in difficulty performing voluntary actions (Benke, 1993) (i.e., opening the mouth to a spoon or moving food from the front to the back of the mouth)
o Work with OT and PT colleagues to help manage these
Dysphagia in PWD
Dysphagia Management in PWD
Screen all patients at risk of dysphagia
Clinical (bedside) swallowing assessment
No Problem Problem
Instrumental swallowing assessment if indicated
(VFSS or FEES)Determine diet
texture + referrals
Monitor over time
Rehabilitative or compensatory intervention
Dysphagia Screening
• Who: all patients in recognized risk groups• Why: reduces risks of aspiration pneumonia, mortality
and need for enteral feeding (Martino et al., 2005)
• When: before initiating oral intake• How: informal vs. formal
• Formal is better – lower incidence of pneumonia (2.4% v. 5.4%) (Hinchey et al., 2005)
• Formal screening has been evaluated in acute stroke population
• Other disorder groups may require different approaches.
Dysphagia Screening
3 oz water swallow test (Suiter, 2008)
Only validated tool for PWD
“Drink all the water until the cup is empty”Fail if:
• Coughing or choking• Wet or hoarse voice quality• Inability to complete task
Either during or within 1 min of completion
Another Screening Option?
Mealtime durations over ~40 minutes are significantly associated with suspected dysphagia in LTC (Namasivayam-MacDonald, 2018)
Implications:• If resident is consistently taking >40 minutes to eat, then a
clinical swallow evaluation is warranted.• Since medical status changes often, screening should be
performed at quarterly check-ups.• Any failed screening should lead to a CSE
• Detailed Chart review• Patient / caregiver interview • Oral-facial and Sensory-Motor (Cranial Nerve) exam• Speech-Language and Cognitive Status• Ability to follow directions • Assessment of vocal quality and respiratory stability • PO trials of various consistencies • Helps form a hypothesis of the problem • Patient's perception of function, severity, change
in functional status and quality of life• Findings help determine management and
need for instrumentals / referrals and develop POC
THE CLINICAL SWALLOW EVALUATION (CSE)
Instrumental Swallowing Assessments
VFSS: Videofluoroscopic Swallow Study• MBSS (Modified Barium Swallow Study)• Dynamic visualization of swallow / bolus flow• Allows for visualization of all swallow stages
FEES: Fiberoptic Endoscopic Evaluation of Swallowing • May be difficult with a patient with severe cog
impairment and/or Parkinsonian tremors• Can only visualize pharyngeal phase• Can see anatomical structures, mucosa,
secretions and secretion management
VFSS VIDEO EXAMPLES:
Normal Swallow, Normal Aging Swallow, Aspiration in Person with Dementia

Enables the SLP to:
• Visualize the structures of the upper aerodigestive tract
• Assess the physiology of swallow structures
• Determine presence, cause and severity of dysphagia
• Identify penetration / aspiration risk
• Determine with specificity the relative safety and efficiency of various bolus consistencies and volumes.
• Assess therapeutic strategies

Dysphagia Intervention Options in PWD
The goal of dysphagia therapy in PWD is to optimize the safety and efficiency of the oropharyngeal swallow, help reduce feeding related
behavior issues, to maintain adequate nutrition and hydration, to improve oral hygiene and to maximize quality of life.
• GOOD ORAL HYGIENE• Consistent environment in the dining room for mealtime/eating• Encouraging smaller meals throughout the day • Consulting with RD about nutritional supplements • Encouraging self-feeding• Making food visually appealing• Reducing clutter and distractions• Providing finger foods • Providing food choices• Focus on patient preferences • CAREGIVER TRAINING
(Amella, 2002; Brush & Calkins, 2012; Chang & Roberts, 2008).
Optimizing Nutrition and Hydration in PWD
Dysphagia Management in PWD
Swallow safety
Quality of life
“Is the burden of treatment outweighing the benefit?” (Ferrell & Coyle, 2010; Palecek & Teno, 2010)
Painter, V., Le Couteur, D. G., et al. (2017). Clinical Interventions in Aging, 12, 1193-1203.
• Are we right about our diet recommendations? o Among nursing home residents, 91% of patients placed on modified diets were on overly restrictive diets. o Only 5% of identified to be on an appropriate diet level matching their swallow ability and 4% of patients
placed on diets above their clinically measured swallow ability. (Groher, 1995)
• Although recommended to promote safe swallowing and reduce aspiration in patients with dysphagia, modified diets may result in reduced food intake and increase the risk of malnutrition / dehydration for PWD (Wright et al, 2008)
• Insufficient evidence found to suggest texture-modified food and fluids produce clinically significant beneficial effects on aspiration, pneumonia, nutrition and hydration, morbidity or mortality for individuals with dementia. (Painter et al., 2017)
Diet Modifications in PWD
Populations most commonly receiving ANH include the general category of dysphagia (64.1%), and patients with Stroke (65.1%) or Dementia (30%)
No data to suggest that tube feeding of patients with advanced dementia prevented Aspiration PNA or prolonged survival rates. (Finucane et al, 1999)
Little evidence that non-oral feeding improves nutritional status or increases life expectancy in advanced dementia
Various factors to consider in PEG placement
Alternate Nutrition and Hydration (ANH) in PWD
Role of the SLP in Palliative Care
SLPs play important role in palliative and end-of-life care
Roles of the SLP: Assistance, Advocacy, Agent of Change
Carefully consider potential harm of dysphagia interventions, such as modified diets and FT placements
Paradigm shift from rehabilitation and compensation, towards palliation and patient-centered care
Caregiver training, support and education
Care, C., Doors, B. C., Book, S., Toolkit, C. G. A., Thames, B. G. S. N. E., Thames, N. W., ... S. A. S. Dysphagia Management for Older People Towards the End of Life. - http://www.bgs.org.uk/
Person-Centered Multidisciplinary Team Approach
• Patient, family, and healthcare professionals are a “unit of care”
• TEAM GOALS: Minimize symptoms and maximize patient’s autonomy
• Ensure that the patients’ best interests remain at the core of the management plan as part of current and emerging goals of care.
• A coordinated approach, particularly towards the end of life is essential for patients with dementia and other chronic, progressive conditions, to ensure consistent transfer of care between acute and community settings.
So – if anyone asks “How can an SLP help?”• Education: Provide patient and family education on the impacts of Dementia diagnosis
on cognition and language, and what can be done to maintain the person’s well-being
• Identification and Compensations: Optimize retained abilities and teach the use of compensatory strategies that will improve the patient’s cognitive/communicative functionas well as establish patterns that will be helpful in the future.
• Therapeutic Intervention: Therapy provided on an ongoing basis as the disease progresses - to develop and modify communication strategies and aids as needed
• Caregiver Support: Training the care partner in effective communication and feeding strategies and aids, to decrease problem behaviors and maximize QOL
We cannot change the disease but….
We can change how we respond to it.
We can change how we think about it.
We can take time each day to focus onwhat remains, strengths, positive momentsof connection, or even laughter.
With help, we can maximize a person’s abilities to help them remain independent, connected to themselves and others, and hopeful.

Brain Structure and Function
• HL is associated with reduced cortical volumes in the primary auditory cortex (Husain et al.,Brain Research, 2010; Peelle et al, J. Neuroscience, 2011; Eckert et al., JARO, 2012)
• Variation in central auditory white matter tract integrity (Chang et al., Neuroreport, 2004; Lin et al., J. Magn Reson Imaging, 2008)
• Faster rates of right temporal lobe atrophy in individuals with hearing loss (Lin et al., Neuroimage, 2014)
Reduced Social Engagement“Blindness separates us from things but deafness separates us from people.“ Helen Keller
• Significant correlation between hearing loss and Objective and Subjective Social Isolation Scale scores (Weinstein & Ventry, JSHR, 1982)
• Older adults with hearing loss are more likely to feel lonely or remote and feelleft out, even in a group (Strawbridge, et al., Gerontologist, 2000)
Increased Cognitive Load
“We hear with our ears, but we listen with our brain”
Capacity Model of Attention (Kahneman, Attention & Effort)oAssumes there is a limit to the capacity to perform mental work
Hearing loss increases the difficulty of listening; increasing the effort it takes to do so, and reducing the effort available to do other tasks, such as remember and respond in conversations.

Testing and Treating
Hearing Testing - Patients with Dementia (PWD)
• Identify functional abilities• Consider anxiety/
paranoia
• Be mindful of dignity and respectoGive patients an “out”
Sperling, R.A., et al (2011)
Hearing Testing - PWD (cont.)
• Reinstruct and redirect as needed
• Narrate procedures- reduces anxietyo “I’m walking behind you to pick up my equipment”o “Ok, now I’m going to put these headphones in your ears”
• Order procedures by priority
Treating Hearing Loss in PWD
Consider the continuum of disease as well as caregiver support
Hearing Loss intervention in (PWD)
Worse hearing is associated with increased neuropsychiatric symptoms (NPS; delusions, hallucinations, agitation, depression, anxiety, etc…) in adults with cognitive impairments
Hearing aid users experience reduced NPS
Effective communication may help manage NPS
