From the Guidelines
The next best step for this 71-year-old female long-term care resident with dementia and persistent aggressive behavior despite current medications would be to increase the quetiapine dose gradually, starting with 25mg twice daily and titrating up as needed while monitoring for side effects, as recommended by the American Psychiatric Association practice guideline on the use of antipsychotics to treat agitation or psychosis in patients with dementia 1. Before medication changes, a comprehensive assessment should be performed to identify potential triggers for the aggressive behavior, such as pain, infection, constipation, or environmental factors. Non-pharmacological approaches should be optimized, including:
- Consistent daily routines
- Appropriate sensory stimulation
- Staff training in dementia care techniques If quetiapine adjustment is ineffective, consider a geriatric psychiatry consultation for alternative medication options like risperidone or olanzapine at low doses, as suggested by guidelines for managing Alzheimer's disease 1. Antipsychotics carry black box warnings for increased mortality in elderly patients with dementia, so their use should be carefully considered with regular attempts to taper once behavior stabilizes, as noted in the guidelines for managing agitation in patients with dementia 1. Regular monitoring for extrapyramidal symptoms, sedation, orthostatic hypotension, and metabolic effects is essential with any antipsychotic medication.

From the Research
Aggressive Behavior in Dementia Patient
The patient is a 71-year-old female with dementia and aggressive behavior, currently being treated with fluoxetine, bupropion, and quetiapine 6.25mg po BID.
- The current treatment regimen includes quetiapine, which has been shown to be effective in reducing aggressive behavior in patients with dementia 2.
- However, the patient's aggressive behavior persists, suggesting the need for an alternative or additional treatment approach.
Alternative Treatment Options
- Risperidone has been shown to be effective in reducing aggressive behavior in patients with dementia, and may be considered as an alternative to quetiapine 2, 3.
- Olanzapine has also been shown to be effective in reducing aggressive behavior in patients with dementia, and may be considered as an alternative to quetiapine 4, 5, 3.
- Haloperidol may also be considered, but it has been associated with a higher risk of extrapyramidal symptoms compared to atypical antipsychotics such as quetiapine, risperidone, and olanzapine 4, 5.
Considerations for Treatment
- When selecting an alternative treatment, it is essential to consider the patient's medical history, current medications, and potential side effects of the new treatment.
- Non-pharmacological interventions, such as behavioral therapy and environmental modifications, should also be considered as part of a comprehensive treatment plan.
- Monitoring for orthostatic hypotension is crucial when using antipsychotic medications, especially in elderly patients 6.
