Understanding Dementia in Occupational Therapy

Understanding Dementia: An Occupational Therapy Perspective

• Dementia is a chronic, progressive decline in cognitive functions (memory, thinking, problem-solving) impacting daily life
• Common causes include Alzheimer's disease (60-80%), vascular dementia, Lewy body dementia, and frontotemporal dementia.

Symptoms of Dementia - Early Stage

• Key features include subtle memory lapses, difficulty organizing/planning tasks, mild confusion in unfamiliar environments, losing/misplacing items, changes in mood (increased irritability/anxiety)
• Impact on function: may still function independently but require reminders or assistance with complex tasks; possible social withdrawal due to fear of forgetting conversations/events
• Occupational therapy tips include introducing memory aids (calendars, labeled storage), simplifying routines, and educating the client and family on early signs and intervention

Symptoms of Dementia - Middle and Late Stages

• Middle stage symptoms include increased difficulty recognizing people/places, language problems (forgetting words, inappropriate substitutions), behavioral changes (agitation, wandering, delusions), and reduced ability for ADLs (dressing, grooming)
• Impact on function: requires assistance with daily activities; possible unsafe behaviors, challenges maintaining relationships due to impaired communication
• Occupational therapy focuses on developing structured routines to minimize confusion, providing caregiver training, and exploring sensory-based activities for calming agitation

Late Stage Dementia

• Symptoms include severe memory loss (forgetting immediate family), dependency on caregivers for all ADLs (feeding, toileting), loss of mobility, difficulty swallowing/speaking, and full-time care needed
• Impact includes minimal social engagement, often limited to basic sensory responses.
• Occupational therapy focuses on sensory stimulation (e.g., music, touch), modifying the environment to support mobility/safety, caregiver support for end-of-life care strategies and stress management.

Importance of Occupational Therapy in Dementia

• Role of occupational therapy includes maintaining independence in daily routines, adapting activities to meet client capabilities, and educating caregivers on supporting clients effectively.
• Occupational therapy focuses on person-centered care which enhances engagement in meaningful activities.

Occupational Therapy Assessments for Dementia

• Cognitive function assessments include the MMSE (Mini-Mental State Examination) and MOCA (Montreal Cognitive Assessment)
• Functional abilities assessments include FIM (Functional Independence Measure), and AMPS (Assessment of Motor and Process Skills)
• Behavioral and emotional assessments include NPI (Neuropsychiatric Inventory) and Cornell Scale for Depression in Dementia
• Caregiver burden assessments include the Zarit Burden Interview.

OT Interventions in Dementia

• Cognitive strategies include memory aids (labeled drawers, digital reminders), reminiscence therapy.
• Activity-based interventions include simplified ADL training, creative arts (painting, knitting) for stimulation
• Environmental modifications to create clutter-free/well-lit spaces, clear signage.
• Behavioral management strategies use sensory integration approaches (weighted blankets, aromatherapy) for agitation, redirection techniques for caregivers.
• Caregiver support emphasizes task simplification and managing stress/burnout.

Case Study Example

• 72-year-old with Alzheimer's in middle stage, challenges include wandering, dressing difficulties and agitation during bathing.
• Occupational therapy approach includes a structured daily routine, introducing adaptive clothing, and using calming music during bathing.

Challenges in OT for Dementia

• Barriers include limited patient insight into their condition, family/caregiver resistance to recommendations, and variability in progression/symptoms.
• Solutions include building rapport with clients/families, providing clear actionable advice with demonstrations, and advocating for dementia-friendly community resources.

Summary and Takeaways

• Dementia is a complex condition requiring a holistic, person-centered approach.
• Occupational therapy interventions focus on improving quality of life for both clients and caregivers.
• Assessments and interventions must be tailored to individual needs.

Resources for OT Students

• Key references include AOTA Practice Guidelines for Adults with Dementia, WHO Dementia Guidelines, and Alzheimer's Association resources
• Learning resources include Dementia Care Certification Courses and case-based OT simulations
