Psychological Symptoms
Mood Symptoms
Psychotic Symptoms
Sleep Disturbances
Why Is BPSD Important?
• Lifetime risk is nearly 100%
• Associated with increased morbidity
and nursing home placement
• Potentially treatable
Case: Part 1A
1. What Do You Do Next?
a. Start haloperidol 0.5 mg at night
b. Start risperidone 1 mg at night
c. Increase donepezil to 10 mg
d. Increase oxybutynin to 10 mg twice a day
e. Increase acetaminophen to 1000 mg twice a
day
f. Clarify the history and perform a careful
physical and neurologic exam
Evaluation of BPSD
1. Obtain a History - clear description of the
behavior from the patient & others
• Temporal onset, course
• Associated circumstances
• Relationship to key environmental
factors
• In context of the patient’s medical, family
and social history
Evaluation of BPSD
2. Careful Physical & Neurologic Exam
Assess Mental Status
Pay attention to:
• Appearance and Behavior
• Speech
• Mood
• Thoughts and Perceptions
• Cognitive Function
• Attention
Evaluation of BPSD
3. Lab Studies
•
CBC and metabolic panel in all cases of
new onset BPSD
•
Brain imaging, EKG, CXR, and urinalysis
based on the history and exam
Evaluation of BPSD
R/O Delirium
• Acute Conditions such as pneumonia,
UTI, pain, angina, constipation, poorly
controlled diabetes, electrolyte imbalance
• Medication Toxicity or adverse effects
of medications due to new or existing
medications
Evaluation of BPSD
R/O Environmental Causes
1. Make sure pt’s basic physical needs are met
2. Environmental Precipitant
• Disruptions in routine
• Over Stimulation
• Under Stimulation
Evaluation of BPSD
After medical, environmental, and
care giving causes are excluded, it
can be concluded that the primary
cause is progression of the dementia

Review nonpharmacologic, patient-centered
interventions
Guidelines for Management of BPSD
1997 Consensus statement from the American
Psychiatric Association
2003 Consensus statement from the American
Geriatrics Society and American Association
for Geriatric Psychiatry
Guidelines for Management of BPSD
Nonpharmacologic Interventions First
• 40% of BPSD symptoms spontaneously
resolve; “they come and go”
• Placebo response can be quite substantial
• No FDA approved medications for psychosis
in AD
Nonpharmacologic Strategies:
To Minimize Development of BPSD
• Maintain a structured daily routine
• Environmental modifications
• Utilize good communication skills
• Encourage independence in ADLs
Nonpharmacologic Strategies:
To Minimize Development of BPSD
Person-Centered
Showers and Towel Baths
• Create environment based on patient
comfort and preference
• Cover with towels to maintain
warmth and modesty
• Use no-rinse soap and warm water
• Use gentle massage to cleanse
• Modify shower spray

Nonpharmacologic Strategies:
Agitation/Aggression (<1/wk)
1. Identify the precipitating factor and avoid
the triggers
2. Distraction Techniques
3. Behavior Modification
• Positive reinforcement of desirable
behavior
Nonpharmacologic Strategies:
Agitation/Aggression (<1/wk)
4. Environmental Modifications
•
•
•
Preferred music
Aromatherapy-lavender
Light and pet therapy
5. Exercise and structured activity therapies
***Physical restraints should be avoided

were not to deviate no more than 30 minutes
from the selected times
•
Encouraged patients not to nap after 1 PM and
limit naps to 30 minutes or less
•
Walk for 30 minutes exercise daily
•
Reduce light/noise levels in their sleeping areas
Matching Target Symptoms
Sleep-wake Cycle Disturbance >1 Month
Nonpharmacologic Interventions
•
Switch to decaffeinated drinks and reduce
evening fluid consumption

schedules at night, use of incontinence pads,
exclude urinary tract infections
•
Eliminate triggers for nighttime awakenings ie
control night time pain, give nightly snack, take
activating meds in the AM

Pharmacologic Therapy for primary sleep disturbances
when nonpharmacologics fail
• Benzodiazepine receptor agonists
• Atypical Antipsychotics
• Cholinesterase inhibitors
• Melatonin as a hypnotic in this population appears
equivocal

Management Strategy for This Patient?
a. Enrollment in Adult Day Health Care Center
b. Caregiver education and training in coping
skills
c. Prescribe nortriptyline 25 mg
d. Prescribe sertraline 25 mg
e. ECT (Electroconvulsive Therapy)
Matching Target Symptoms
Mood Symptoms in AD: Depression
Depression of 2 weeks’ duration resulting in
significant distress or sustained depressive
features lasting more than 2 months
Consider:
Antidepressants –first line: SSRIs
• Citalopram
• Sertraline (improved depressive symptoms and
ADLS w/o improving cognition in patient with AD and
depression)
• Avoid fluoxetine and paroxetine
Case: Part 6
6. What Would You Do Next?
a.
b.
c.
d.
Switch to another agent in same class
Switch to another agent in another class
Titrate dose of initial medication
Add methylphenidate 5 mg
Matching Target Symptoms
Mood Symptoms in AD: Depression
If a first agent has failed an adequate
therapeutic dose for 8 to 12 weeks, consider
alternatives:
•
•
•
•
Bupropion
Mirtazapine
Venlafaxine
Tricyclic agents (desipramine and nortriptyline)
Matching Target Symptoms
Mood Symptoms in AD: Depression
For partial responders to an antidepressant,
consider augmentation strategies
• Methylphenidate ????
Matching Target Symptoms
Mood Symptoms in AD: Depression
If depression remains and patient is in
danger of serious weight loss or suicidal
ideas despite several antidepressant trials,
consider ElectroConvulsive Therapy
*No RCT in BPSD or geriatric pts
Matching Target Symptoms
Mood Symptoms in AD:
Manic-like Behavioral Syndromes
Mood syndromes characterized by:
• Pressured speech, disinhibition, elevated mood,
intrusiveness, hyperactivity, and reduced sleep
Consider:
• Mood-stabilizing agents
• Carbamazepine, lamotrigine, or ?lithium
Matching Target Symptoms
Mood Symptoms in AD: Hypersexuality
If hypersexuality occurs in association with a
recognizable syndrome such as a manialike state, treat the specific syndrome first
First, try Nonpharmacologic Interventions:
• Separating pt from others during social situations
• Change dinner table assignment
• Switch staffing to male attendants when possible
• Redirection and distraction
Matching Target Symptoms
Mood Symptoms in AD: Hypersexuality
Consider:
Antiandrogen
•
•
•
Progesterone-MPA
Leuprolide acetate
Cyproterone acetate, Cimetidine, Spironoloctone,
Ketoconazole
Estrogen
Serotinergics: SSRIs, Effexor, Clomipramine, TCA
Gabapentin
Antipsychotics
Matching Target Symptoms
Mood Symptoms in AD: Hypersexuality
Caveat:
Fronto-Temporal Dementia is often associated
with prominent disinhibition and
perseveration. In severe cases, a
syndrome of hyperphagia, hyperactivity
and hypersexuality may occur related to
bilateral temporal lobe atrophy
Case: Part 7
7. What Is Your Recommendation?
a.
b.
c.
d.
e.
Refer for nursing home placement
Do a time-limited trial of haloperidol 0.5 mg
Do a time-limited trial of risperidone 0.5 mg
Do a time-limited trial of olanzapine 5 mg
Do a time-limited trial of valproate 250 mg
Guidelines for Management of BPSD
1997 Consensus statement from the American Psychiatric
Association endorse:
– Matching target symptoms to relevant drug class
2003 Consensus statement from the American Geriatrics
Society and American Association for Geriatric
Psychiatry recommends:
– Atypical antipsychotic as 1st line for treatment of severe
behavioral symptoms with psychotic features in patients
with dementia
– SSRI’s are first recommended treatment for patients with
dementia presented with depression
Systematic reviews, Meta analysis, Randomized controlled
trials 2004+
Psychosis in Dementia
Clinical criteria for diagnosis of AD with
psychosis:
Presence of intermittent delusions or
hallucinations occur for at least 1 month and
must cause distress
Pharmacologic Interventions
• If nonpharmacologic interventions fails or
if “agitated” behaviors are too harmful to
patient or others, consider pharmacologic
agents
• What to prescribe?
Matching Target Symptoms
Agitation & Aggression in Dementia
• Antipsychotics
Atypical (Risperdal, Aripiprazole, Olanzepine)
versus conventional (Haloperidol)
• Cholinesterase Inhibitors
• SSRI
• Anticonvulsants/Mood Stabilizers
Antipsychotics
Conventional: Haloperidol
• Might be effective in treating aggression in
patients with dementia but side effects
limits its use; extrapyramidal symptoms
• Risk for neuroleptic malignant syndrome,
tardive dyskinesia, orthostasis, and
prolong QTc
Atypical Antipsychotics
• Although there is a significant improvement in
aggression with risperidone and olanzapine and
psychosis with risperidone, the significantly higher
risk of serious cardiovascular effects including stroke
and extrapyramidal symptoms outweighs the benefit
• A large multi-center, double-blind, placebo controlled
trial comparing olanzapine, risperidone and
quetiapine with placebo for patients with Alzheimer
dementia with BPSD and MMSE bet 5-26 showed
modest trends or no significant effects on symptoms
in comparison to placebo
Cochrane Database of Systematic Reviews 2006
NEJM 2006;355:1525-38.
Blackbox Warning
for Atypical Antipsychotics
• Increased risk of mortality. Rate of death was 1.6 to
1.7 times that of placebo
• Death appeared to be heart related or from
infections (eg, pneumonia)
• Diabetes mellitus, hyperglycemia, ketoacidosis, and
hyperosmolar states
http://www.fda.gov/cder/drug/infopage/antipsychotics/default.htm
Cholinesterase Inhibitors
Donepezil
• Not a significant advantage over placebo for treatment of
agitation in patients with severe dementia
N Engl J Med 2007; 357; 14 (1382-1392)
Galantamine
• Improvement of behavioral symptoms in patients with
mild to moderate dementia. The effective dose was 16
mg daily (as effective as 32 mg daily) titrated over 4
weeks. This dose was achieved over 4 weeks. The
higher dose might have higher rate of adverse effect
without any added benefit
Cochrane Database Syst Rev. 2006
Anticonvulsants
Valproate (Cochrane Database of Systematic Reviews 2007 Issue 4)
• Low dose is ineffective and high dose is associated with
increased rate of adverse effects
• Side effects: somnolence, thrombocytopenia, infection
Gabapentin (International psychogeriatrics; Nov 2007)
• No RCT
• Generally well tolerated but has reported alarming side effects
including case reports of abrupt aggravation in patients with
Lewy body dementia
Carbamazepine (International psychogeriatrics; Nov 2007)
• Equivocal information on efficacy of carbamazepine based on
limited RCT trials. Additionally safety and tolerability are other
concerns
• Another concern is drug-drug interaction
Other Treatments
Memantine
• Two out of three RCT showed that patients with moderate and
severe Alzheimer dementia displayed less agitation on
Memantine 20 mg /day at 6 months. Unpublished data shows
no clinically detectable effect in patients with mild to moderate
dementia. Cochrane Database of Systematic Reviews 2007 Issue 4
SSRI
• Limited studies. No Cochrane review
• In a RCT double blind trial of Citalopram comparing to
Perphenazine and placebo in pts with dementia (mean MMSE
6.4-9.9) and BPSD in acute inpatient showed significant
improvement in agitation, aggression, psychosis, lability, and
tension factor with short course of both Citalopram and
Perphenazine. Additionally cognition and retardation
significantly improved in Citalopram group. No difference in
side effect profile among 3 groups. Am J Psychiatry 2002; 159:460-465
Other Treatments
Trazodone
• Limited trial indicates no significant difference
between Trazodone (dose of 50-300 mg
daily) and placebo in treatment of behavioral
and psychosocial manifestation of dementia.
Cochrane Database of Systematic Reviews. 4, 2007
Take Home Points
• Always obtain a thorough history about the “disturbance”
• Rule out delirium and other environmental factors
contributing to the disturbance
• Use nonpharmacologic interventions for BPSD first
• Consider “targeted,” time-limited pharmacologic trials for
severe or persistent BPSD symptoms given modest evidence
of efficacy and moderate potential for harm
