What are common behavioral disturbances? • Agitation • Physical • Verbal • Resistiveness • Mood • Depression • Anxiety
What are common behavioral disturbances? • Psychosis • Disruption in the ability to differentiate real from unreal • Hallucinations • Illusions • “Sundowning”
Assessment • Rule out any environmental disturbance • change in home setting • change in the staff/family members • death of a pet
Assessment • R/o any possible medical illness • urinary tract infection • dehydration
Assessment • R/o drug-drug interactions or drug intolerance
Assessment • When does the behavior occur • constant regardless of stimuli • specific time of day • with caregiving activity
Assessment • Endocrine • Iatrogenic - consider non-prescription medications • Injury • Intoxication
Treatment • Behavioral Intervention • Antidepressant medications • Antipsychotic medications
What is Psychosis? • The state in which a person is unable to differentiate “real” from “unreal” • Misperception of stimulus • Hallucinations • Illusions • Delusions • Agitation
Antipsychotic Medications(doses adjusted for the geriatric age group) • haloperidol (Haldol) .5 - 2.0mg • risperidone (Risperdal) .5 - 6.0mg • olanzapine (Zyprexa) 2.5 - 10.0mg • ziprasidone (Geodon) 20-40mg • quetiapine (Seroquel) 25mg - 300mg***
General Guidelines • Monitor very carefully for side effects • Monitor for benefit • Consider decreasing the dose if symptoms improve • Monitor for increased sedation and adjust the time of dosing
Deaths with Antipsychotics in Elderly Patients with Behavioral Disturbances • 15 out of 17 placebo-controlled trials showed numerical increases in mortality in the drug-treated group compared to the placebo-treated patients • N = 5106 involving Risperidone (7 trials), Olanzapine (5 trials), Aripiprazole (3 trials) and Quetiapine (2 trials) • ~1.6-1.7 fold increase in mortality in active treatment over placebo • Specific causes of these deaths: • Heart related events (e.g., heart failure, sudden death) or infections (mostly pneumonia) FDA Public Health Advisory (4/05)
Adverse Effects with Atypical Antipsychotics • Dyslipidemia • Glucose metabolism change • Possibility of sudden death secondary to heart failure, cardiac event or infection
Adverse Effects with Atypical Antipsychotics Clinical Considerations: • What are the risk factors of this particular patient? (history of cardiac problems, diabetes, and or hypertension?) • What alternative treatments have been tried – what was the response?
Adverse Effects with Atypical Antipsychotics Clinical Considerations: • What benefits does the patient receive from the particular antipsychotic vs. how is the patient’s behavior without or prior to the initiation of the medication? • Have other intervention methods or medications been tried already?
Adverse Effects with Atypical Antipsychotics Recommendations for management: • Document need • Discussion of alternate treatments • Patient/Family consent • Use lowest possible doses – monitor for side effects
