3. Structure of Presentation Short-term prescribing with antipsychotics for Dementia*
Efficacy associated with the antipsychotics
Adverse events associated with the antipsychotics
Long Term Prescribing
Efficacy associated with the antipsychotics
Adverse events associated with the antipsychotics
4. Up to 3 months
5. Non AD dementias Vascular dementia (VaD) Some VaD patients in 2 of the risperidone studies.
DLB/PDD only 1 RCT (with quetiapine), showing no significant benefit. Serious potential concerns re neuroleptic sensitivity
Marked need for treatment studies examining treatment of neuropsychiatric symptoms in non-AD dementias, including trials of antipsychotics
6. Risperidone Efficacy: BEHAVE-AD
7. Schneider et al 2006 Aripiprazole
10. STAR TRIAL: Zhong et al 2007
11. Interim conclusion Risperidone* and Aripiprazole are effective in the short term treatment of aggression and possibly agitation
12. Adverse events with Risperidone
15. Mortality and antipsychotics in people with dementia
16. Interim conclusion There are serious safety concerns with atypical antipsychotics, but the absolute risk with short term treatment is modest - eg mortality 1%.
17. 6 12 months
19. Clinical Antipsychotic Trials of Intervention EffectivenessAlzheimers Disease (CATIE-AD)
20. CATIE: Discontinuation
21. Responses to atypical antipsychotics
22. Antipsychotic withdrawal studies Bridges-Parlet et al, 1997
Cohen-Mansfield et al, 1999
Ballard et al, 2002
RCT studies, 6 weeks3 months
Total >180 participants
No significant worsening of BPSD in any of the studies
23. Change from Baseline to 6 months
25. Change from Baseline to 6 months : Cognition
26. Month 12 Outcome
28. Differential Survival
31. Conclusion For longer term treatment, the safety concerns outweigh the limited efficacy of antipsychotics for the treatment of BPSD
However, atypical antipsychotics have the best evidence base for a pharmacological therapy for the short term treatment of aggression/agitation and therefore continue to play an important role in the short term treatment of agression/agitation in people with Alzheimers disease
