Approaches to behavioral and psychological symptoms of Dementia Marie-France Rivard, MD, FRCPC Division of Geriatric Psychiatry University of Ottawa
Objectives Describe the causes of common psychological and behavioral symptoms in dementia (BPSD) Introduce the purpose of the PIECES program Identify appropriate interventions Advise on the role of pharmacotherapy
Disclosure slide Over last 28 years, received honoraria for Continuing education activities from most pharmaceutical companies and some grants for research. Over last 7 years, no direct funding for research or Continuing Education: honoraria by organizing committees who may have, in turn, received un-restricted grants. Currently Chair, Seniors Advisory Co to MHCC, mostly volunteer work.
Prevalence of BPSD 90% of patients affected by dementia will experience Behavioral and Psychological Symptoms of Dementia (BPSD) that are severe enough to be labeled as a problem during the course of their illness. Agitation (75%) Wandering (60%) Depression (50%) Psychosis (30%) Screaming and violence (20%) are most common
Impact of BPSD 50 – 90% of caregivers considered physical aggression as the most serious problem they encountered and a factor leading to institutionalization. (Rabins et al. 1982) Front-line staff working in LTC report that physical assault contributes to significant work related stress (Wimo et al. 1997) Agitation, depression, anxiety, paranoid ideation cause significant suffering.
Adapted from McShane R. Int Psychogeriatr 2000;12(suppl 1): 147 BPSD Symptom Clusters Pacing Repetitive actions Dressing/undressing Restless/anxious Hallucinations Delusions Misidentification Suspicious Agitation Physical aggression Verbal Aggression Aggressive resistance to care Sad Tearful Hopeless Guilty Anxious Irritable/screaming Suicidal Withdrawn Lacks interest Amotivation Psychosis Depression Apathy Aggression Euphoria Pressured speech Irritable Mania
Causes of BPSD What is P.I.E.C.E.S. Person-centered assessment and care planning approach, using the care team to develop hypotheses and test the implementation of possible solutions. An acronym that conveys the individuality and importance of the various factors that contribute to BPSD in dementia. These factors are: Physical, Intellectual, Emotional, Capabilities, Environment and Social
P.I.E.C.E.S. Taught in Ontario since 1998 to LTC registered staff From 1999-2007 expanded to include administrators of LTC, unregistered staff, acute care hospitals, CCAC case managers 2007-08: PIECES program for physicians: Soon available for distribution Soon available for distribution To be tested with family health teams and utilized by Peer Presenters and Preceptors of Ontario’s Alzheimer strategy To be tested with family health teams and utilized by Peer Presenters and Preceptors of Ontario’s Alzheimer strategy
Why use the P.I.E.C.E.S. approach? Identification of target behaviors which present risk or urgency Flags possible delirium Framework for synthesis of non- pharmacologic approaches Nutrition, comfort, hydration, sleep, etc… Nutrition, comfort, hydration, sleep, etc… Environment, personhood, social, stimulation Environment, personhood, social, stimulation Guide the pharmacologic approach
PIECES Template The Three Question Template 1. What has changed? 2. What are the RISKS and possible causes (using the PIECES framework)? 3. What is/are the action (s)?

P.I.E.C.E.S. tools Daily Observation Sheet (DOS), A-B-C charting Shows frequency, severity, patterns of behaviours, can be individualized Shows frequency, severity, patterns of behaviours, can be individualized Cohen Mansfield Agitation Inventory (CMAI) Identifies behaviours and severity over 7 day period Identifies behaviours and severity over 7 day period Confusion Assessment Method (CAM) Delirium screen Delirium screen MMSE, MOCA, Clock Sig: E Caps, Cornell Depression Scale
Other Common Tools ScaleAssessment CMAI The Cohen-Mansfield Agitation Inventory 29 agitated behaviors rated by caregiver on 7 point frequency scale NPI-NH Neuro-psychiatric Inventory- Nursing Home Version 12 items rated by caregiver on a 4 point frequency and a 3 point severity scale BEHAVE-AD The Behavioral Pathology in Alzheimer’s Disease Rating Scale 25 symptoms rated by caregiver on a 4 point severity scale
Caregiver Scales Useful for patients in the community Self report can be used in office setting or home visit Allow caregivers to identify behaviours they may not be comfortable talking about in front of their loved one ie - Kingston Behavioural Assessment
Pharmacological treatment Clear indication, potential benefits Expected time to response Risks associated with and without Rx Appropriate dose range Monitoring for side effects and response When to consider dose reduction, discontinuation.
Top Ten Behaviors not (usually) responsive to medication Hiding/hoarding Pushing wheelchair bound co-patient Eating in-edibles Inappropriate isolation Tugging at/ removal of restraints Aimless wandering Inappropriate urination /defecation Inappropriate dressing /undressing Annoying perseverative activities Vocally repetitious behavior
Top Ten Behaviors responsive (perhaps!) to medication Physical aggression Verbal aggression Anxious, restless Sadness, crying, anorexia Withdrawn, apathetic Sleep disturbance Wandering with agitation/aggression Vocally repetitious behavior Delusions and hallucinations Sexually inappropriate behavior with agitation
Pharmacological treatment: When (indications) Behaviors that have not responded to non- pharmacological treatment.

Risks present when there is no pharmacological Rx Risks of injury (self and others), exhaustion, severe and prolonged suffering, increased risk of death with depression, etc. Need to present the risks of not treating with medications to pt or SDM when obtaining informed consent.
Risks associated with pharmacological Rx Risks of antidepressants: Hyponatremia Hyponatremia Increased agitation/insomnia/suicide in first few weeks Increased agitation/insomnia/suicide in first few weeks GI upset and bleed if previous ulcers GI upset and bleed if previous ulcers Headaches Headaches Risks of anti-psychotics Increase risk of death (all antipsychotics), increased QT, cerebrovascular accident Increase risk of death (all antipsychotics), increased QT, cerebrovascular accident EPS and tardive dyskinesia EPS and tardive dyskinesia Worsening of vascular risk factors (increased weight, lipids, diabetes) Worsening of vascular risk factors (increased weight, lipids, diabetes) Risks of benzodiazepines: Falls, ataxia, worsening dementia, memory, disinhibition Falls, ataxia, worsening dementia, memory, disinhibition
Using minimal effective dose, only for the duration required Consider dose reduction for antipsychotic as soon as there is clear therapeutic response to prevent development of side effects Review anti-psychotic medication for possible discontinuation Q 6 months Maintain full dose of antidepressant but review if still needed after 1-2 years? Only if no prior history of depression
Family physicians are at the core of the treatment team, working with: Patients and substitute decision makers Other caregivers (home care, LTC staff) Community resources (Alzheimer Society, First Link programs) Consultants such as PRCs, Outreach teams, Specialized geriatric medicine and mental health services
Questions and further readings Program for physicians should be available in the coming months: distribution strategies? CCSMH guidelines on LTC issues, depression, delirium and suicide New Canadian Consensus guidelines on Dementia.
