“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.

“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

Behavioral and Psychological Symptoms of Dementia
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)

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

Environmental Factors
Noise levels – over stimulation/elevated noise levels can be antagonistic
Lack of social stimulationInappropriate music – ensure age related
and appropriate to the client groupEnvironment/layout
Is it conducive to the specific client group? Could it potentially increase confusion and
disorientation in people suffering from cognitive impairment?

AntipsychoticsMainstay of psychopharmacological treatment
Up to 40% of all dementia patients prescribed antipsychotics1
Atypicals vs. typicals: perceived safety advantage
In patients with dementia, atypicals increase: risk of death (OR=1.5 - 1.7) cerebrovascular adverse events (OR=2.7) rate of cognitive decline

Atypical AntipsychoticsAntipsychotic # trials Bottom LineRisperidone 5 RCTs • Provides best
evidence for treating aggression
• Modest but significant improvement vs. placebo
• Biggest effect size: 2 mg daily
Olanzapine 5 RCTs(fixed dose 1-15 mg daily, 6-10 weeks of treatment)
• Conflicting evidence
• More adverse events of hostility, abnormal gait, somnolence
• Not associated with overall efficacy

• Caveat: studied in context of psychosis

AntidepressantsSSRI’s # trials Main findings
Meta-analysis of 9 trials, n=692; five studies compared SSRIs to placebo, only two studies included in meta-analysis1.
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

Anticonvulsants & mood stabilizersDrug Overall findings for
agitation & aggressionBottom 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

Drug Overall findings for agitation & aggression
Bottom line
Gabapentin No 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
Oxcarbazepine One RCT on agitation & aggression
Negative results
Topiramate Lack of RCTs Adverse effect on cognitionUse not supported in BPSD
Lamotrigine Case series, case reports, no RCTs using objective measures
May be effectiveAdverse effects: rash, somnolence, tremor
Lithium Case series, most > 20 y o, lack of valid instruments
Conflicting results

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
