TAREK K. RAJJI, MD, FRCPC CHIEF, GERIATRIC PSYCHIATRY DIVISION CENTRE FOR ADDICTION AND MENTAL HEALTH ASSOCIATE PROFESSOR OF PSYCHIATRY UNIVERSITY OF TORONTO Management of Agitation and Aggression Associated with Alzheimer’s Disease
“One of the first disease symptoms of a 51-year-old woman was a strong feeling of jealousy towards her husband. Very soon she showed rapidly increasing memory impairments; … thought that people were out to kill her, then she would start to scream loudly.” Dr. A. Alzheimer, 1906. Auguste Deter
“From time to time she was completely delirious, dragging her blankets and sheets to and fro, calling for her husband and daughter, and seeming to have auditory hallucinations. Often she would scream for hours and hours in a horrible voice.” Dr. A. Alzheimer, 1906 Auguste Deter
90% of patients during the course of their illness (Tariot, 1999) 60-90% of patients with dementia suffer from BPSD (Lyketsos et al., 2002) Agitation & Aggression (75%) Wandering (60%) Depression (50%) Psychosis (30%) Screaming and violence (20%)
Behavioral and Psychological Symptoms of Dementia Peak during moderate/moderately-severe stages (Reisberg et al., 1987) Agitation/aggression, apathy may continue to increase (Mega et al., 1996) Affective symptoms are more common early in the illness (Rubin et al., 1988)
Agitation/Aggression Incidence: 50% over course of illness (Tariot & Blazina, 1994) Jost & Grossberg, 1996

Treatment Algorithms: Evidence Algorithm use in clinical practice associated with: Improved quality of care Enhanced patient outcomes Reduced health care costs Adli. M et al. 2006. Biological Psychiatry. 59. 1029.
Treatment Algorithms: Evidence StudyyearNInterventionTAUResults IMPACT (late-life depression) 2002Int-906 Cont- 895 -Depression Algorithm -Case manager supervision of primary care -Primary care practitioner - available mental health services Significant: -Decline in depressive sxs, - Decreased symptom severity -increased care satisfaction PROSPECT (late life depression) 2004Int-320 Cont- 276 -Depression algorithm -Case manager supervision of primary care -primary care with education Significant reduction in: -remission time, -sx severity, -suicidal ideation TMAP (Texas Medication Algorithm Project) (depression) 2004Int-175 Cont- 175 -Depression algorithm -psychoeducation -biweekly expert consultation - Outpatient care without algorithm use Significant : improvement in symptom severity and function at 1 year GAP (German Algorithm Project ) (depression) 2009Int-74 Cont-74 -inpatient care with adherence to medication algorithm -inpatient mental health care Significant: decreased time to remission, fewer medication changes in remitters.
Why do we need a pathway? Better Outcomes More Access More Data New Approaches Better Knowledge
Physical Factors Delirium - Dipstix urine, check temperature and bloods e.g. FBC, U&E, LFT, TFT, ESR, CRP, Glucose, Vitamin B12, folate and ferritin levels Dehydration – check above blood levels; especially U&E. Commence on fluid balance chart Pain – complete appropriate pain assessment tool e.g. Abbey Scale Hunger – monitor and complete fluid and diet charts Constipation – monitor bowel habits Tiredness – chart sleep pattern Medication – side effects Medication withdrawals – e.g. benzodiazepines, opiates Sensory Impairment – sight &/or hearing deficit - refer to sensory impairment service for assessment and advice (where applicable) Hypoxia – cyanosis, laboured breathing NHS Forth Valley
Psychological Factors Depression – observe for any mood or behavioural changes. Complete appropriate assessment tool Hallucinations – more commonly seeing&/or hearing things. NB exclude delirium Delusions – more commonly paranoia &/or suspiciousness. NB exclude delirium Sundowning - increased agitation and activity occurring in the late afternoon/early evening NHS Forth Valley
Environmental Factors Noise levels – over stimulation/elevated noise levels can be antagonistic Lack of social stimulation Inappropriate music – ensure age related and appropriate to the client group Environment/layout Is it conducive to the specific client group? Could it potentially increase confusion and disorientation in people suffering from cognitive impairment? NHS Forth Valley
Attending PhysicianDIAGNOSTIC WORK-UP: HISTORYYESYES NONO Name: Sign: Date: (dd/mm/yyyy) Agitation or aggression is present Clinically suspected to be secondary to Alzheimer’s or mixed Alzheimer’s + vascular dementia History consistent with Alzheimer’s or mixed Alzheimer’s vascular dementia Attending PhysicianDECISION TO MOVE FORWARDY ES NONO Name: Sign: Date: (dd/mm/yyyy) Delirium or other causative medication/medical condition identified? Presentation more consistent with non-Alzheimer’s Dementia? If “Yes” exit pathway Is the Agitation and Aggression: Severe? Causing distress to the patient? Or OTHERS? Preventing or interfering with providing necessary care to the patient? Posing a risk to the patient or to others? If “Yes” to ANY questions, proceed with pathway, otherwise exit pathway HospitalistDIAGNOSTIC WORK-UP: PHYSICAL EXAM INVESTIGATIONYESYES NONO Name: Sign: Date: (dd/mm/yyyy) Basic investigation done to rule out other medical causes of cognitive impairment or agitation Guidelines: vital signs, height, weight, waist circumference, CBC with differential, renal function, liver panel, metabolic/endocrine function, B12, urine analysis, urine C&S, lipid profile, fasting glucose +/- HbA1C, micro albuminuria, extended electrolytes, Delirium screening tool (optional) Examples: Confusion Assessment Method, Delirium Symptom Review, Delirium Rating Scale Addition investigations performed as indicated (optional) List additional investigations: ____________________________________________________________________________________ ______

Antidepressants SSRI’s# trialsMain findings Meta-analysis of 9 trials, n=692; five studies compared SSRIs to placebo, only two studies included in meta- analysis 1. Limited trials addressing aggression or agitation Citalopram vs. placebo: ↓ agitation and aggression Citalopram vs. risperidone: improved effect on agitation, better tolerated Some benefit shown for sertraline & citalopram for overall BPSD vs placebo; no statistically significant difference vs. antipsychotics. May have role in treating aggression and agitation Better tolerated than antipsychotics Indicated if depression present 1. Ballard & Corbegtt. Current Opin Psychiatry. 2013 26(3) 252-259. 2.

Anticonvulsants & mood stabilizers Drug Overall findings for agitation & aggression Bottom Line Carbamazapine- Few clinical trials (1 meta-analysis, 3 clinical trials) - Conflicting evidence - ↑ risk drug-drug interactions, poorly tolerated in long-term use Promising for global BPSD, esp. agitation & aggression (dose 300-600 mg over 6-8 wks) Not recommended for routine treatment of agitation Valproate-Meta-analysis: unacceptable rate of adverse effects (esp. sedation) > 15mg/kg/d -3 RCTs: no improvement in aggression; 1 RCT: worsened hostility; Higher quality studies including RCTs and meta-analyses do not support use for agitation; may worsen aggression Yi-Chun & Ouyang. Kaoh J of Med Sci (2012): 28, 185-193.
DrugOverall findings for agitation & aggression Bottom line GabapentinNo meta-analysis or RCTs Data limited (11 case reports, 3 case series, 1 retrospective chart review) well tolerated, some effectiveness for overall BPSD, (mean dose 900 mg daily) - dearth of data OxcarbazepineOne RCT on agitation & aggression Negative results TopiramateLack of RCTsAdverse effect on cognition Use not supported in BPSD LamotrigineCase series, case reports, no RCTs using objective measures May be effective Adverse effects: rash, somnolence, tremor LithiumCase series, most > 20 y o, lack of valid instruments Conflicting results Yi-Chun & Ouyang. Kaoh J of Med Sci (2012): 28, 185-193.
Anticonvulsants & mood stabilizers Summary: CBZ most promising mood stabilizer for patients with aggression, hostility and (possibly) agitation Also effective for global BPSD Effective dose range: 300-600 mg daily over 6-8 weeks
Electro-Convulsive Therapy (ECT) Case series, 4 patients, failed psychotropics 2 to 4 ECT sessions meaningful reduction in symptoms for 3 to 12 months (Grant et al. 2001) Case series, 3 patients with manic-like symptoms, failed psychotropics 1-2 weeks of ECT followed improvement in mania and agitation (McDonald et al. 2001) 92 year-old female, vascular dementia, failed haloperidol 2 ECT sessions BPSD resolves for 3 months (Katagai et al. 2007)
Electro-Convulsive Therapy (ECT) 16 hospitalized patients (mean age = 66.6, SD = 8.3) with mild to severe dementia. 12 patients bilateral ECT 3 patients right unilateral ECT bilateral ECT 1 patient only right unilateral ECT On average, 9 treatments (range: 2 to 15) All patients improving except for one Ujkaj et al. 2012
