Haroon Burhanullah, MD Faculty, Geriatric Neuropsychiatry Department of Psychiatry and Behavioral sciences Johns Hopkins University School of Medicine Presented by: Name goes here July 29th, 2017

2 Disclosures Nothing to disclose. September 19, 2018

3 Learn to reduce the duration of delirium and possibility sitter use
To Identify delirium in early stages and be able to differentiate from dementia. Learn to reduce the duration of delirium and possibility sitter use To identify neuropsychiatric symptoms of dementia and treatment of behavioral symptoms of dementia Info on some clinical trials. September 19, 2018

5 Delirium Transient organic mental syndrome Acute onset
Global impairment of cognitive functions Reduced level of consciousness Fluctuating Increased or decreased psychomotor activity Disordered sleep-wake cycle.

6 Delirium subtypes Hyperactive delirium : agitation, restlessness, attempts to remove medical devices. Hypoactive delirium: decreased responsiveness, lethargy, apathy, withdrawal and flat affect- Its under appreciated in ICU patients Mixed delirium September 19, 2018

7 Etiology Disease induced syndrome- organ dysfunction in sepsis, cirrhosis . Withdrawal from drug/ alcohol – usually hyperactive delirium Iatrogenic-medication(benzo,opioids,etc Environmental – Sleep disturbance, immobilization and sensory deprivation(eye glasses, hearing aids) September 19, 2018

8 Pathophysiology Neurotransmitter imbalances: Deficiency in acetylcholine and serotonin and activation of dopamine and glutamate Inflammation: IFN alpha or beta, CRP, IL 6, 8, 10 – not measured in clinical practice September 19, 2018

9 Pathophysiology- contd.
Cortisol: has delirious effects on memory when in excess Oxidative impairment: Decrease oxygen supply to brain- inadequate oxidative metabolism and cerebral dysfunction September 19, 2018

10 Delirium diagnosis Predisposing Factors- age >65 , chronic pathology- HTN, stroke, Dementia Precipitating Factors: Acute illness, infection, seizure, TIA, infarcts, metabolic imbalance, medications, NMS or serotonin syndrome etc. Environmental factors, restraints, immobilization, sleep disturbance September 19, 2018

11 Patient history (acute onset, fluctuating course, decrease cognition)
Behavioral observation (delusion, hallucinations, mood lability,) Cognitive assessment (scales) September 19, 2018

12 WORK UP Physical exam CBC, CMP, UA, Blood and urine culture, O2 sat, EKG, Chest X ray, CT scan head and Lumbar puncture EEG September 19, 2018

13 Behavioral symptoms in Delirium
Sleep wake cycle (falling asleep during conversation, circadian fragmentation) Perceptual disturbances Lability of affect Motor agitation/retardation Orientation Attention September 19, 2018

14 Agitation ( removing tubes etc) Memory (STM and LTM)
Visuospatial ability - Fluctuation of symptom severity September 19, 2018

15 Cognitive assessment scales
CAM ICU ( great sensitivity for ICU patients) assess acute onset and fluctuating course, inattention, disorganized thinking and altered level of consciousness. 4AT (rapid delirium assessment, no copyright ) September 19, 2018

16 MMSE ( minimental scale)
Delirium rating scale MMSE ( minimental scale) EEG ( good for nonconvulsive or subclinical seizures) September 19, 2018

17 Prevention of Delirium
Act early- Triage Nurse to do 4AT on confused patients. Review Medications. Manage pain, infection, dehydration, constipation and hypoxia Early mobilization may reduce the incidence and duration of delirium (early Physical therapy and OT) September 19, 2018

18 Prevention Appropriate day/ night light exposure Orient the patient
Consider cognitive stimulating activities, family visits, promotion of good sleep Avoid benzodiazepine, minimize narcotics, Manage withdrawal September 19, 2018

19 Medication considerations for hyperactive delirium / agitation
American delirium society clinical guideline states that antipsychotics can shorten the duration of delirium American geriatric society guidelines recommends lowest possible dose of antipsychotic for agitation in delirium Haldol 1-2 mg Q12 or Zyprexa 2.5mg Q12 hr September 19, 2018

20 Withdrawal symptoms associated with delirium
Delirium tremens : combination of CNS excitation (agitation, delirium, seizures) and hyperadrenergic symptoms (HTN, increased HR) Valium, lorazepam Non FDA approved Gabapentin, Depakote September 19, 2018

22 Dementia Global impairment of cognitive functions in the setting of a clear sensorium Cortical Dementias e.g. Alzheimer’s disease 4 As: amnesia, aphasia, apraxia, agnosia Subcortical Dementias e.g. HD, PD 4 Ds: dysmnesia, dysexecutive, delay, depletion

23 Memory Ability to learn, retain, and recall information and experiences Getting information via sensory organs (registration) Processing the information (encoding) – requires attention Storing the information (retention) Recalling the information (recall)

24 Cortical Dementias e.g. Alzheimer’s disease 4 As:
Amnesia: a partial or total loss of memory Aphasia: loss of ability to understand or express speech Apraxia: inability to perform particular purposeful actions Agnosia: inability to interpret sensations and hence to recognize things

25 Subortical Dementias e.g. HD, PD 4 Ds:
Dysamnesia: memory impairment, patients may benefit from cues Dysexecutive: related to troubles with decision-making Delay: related to slowed thinking and moving Depletion: reduced complexity of thought

26 NPS in dementia Disorders of connectivity
Inferences from brain lesions have not been very enlightening into NPS mechanisms NPS likely due to changes in brain circuitry (connectivity) Structural connectivity Reflected in gray and white matter changes Diffusion tensor imaging particularly helpful Functional connectivity Alterations in neurotransmission Resting state fMRI PET imaging of neurochemistry

27 Agitation/aggression in AD Clinical characteristics (CitAD) derived from NPI
Emotional agitation: distress, upheaval, anger, tension, anxiety, inability to relax Lability: rapid changes in mood, easily irritable, unexpected outbursts, overreacting, catastrophizing Psychomotor agitation: pacing, rocking, gesticulating, pointing fingers, restless Verbal aggression: yelling, excessively loud voice, screaming, uses profanity, threatens, "in your face" Physical aggression: grabs, shoves, pushes, resists, hits, kicks, gets in the way Perceptual disturbance

28 Clinical examples 72 y.o. man who paces and asks to go home, most days starting at about 4pm, while at home with his wife (sundowning) 87y.o. woman who becomes combative with whomever tries to help her take a bath in the nursing home (agitation with personal care) 69y.o. woman who barricades in her room and says others are stealing from her (persecutory delusions) 77y.o. man who refuses to eat or stop watching TV becomes angry and upset when asked to do otherwise (depression) 91y.o. woman who starts screaming every time she looks at herself in a mirror (agnosia) 75y.o. woman who suddenly has trouble getting to sleep and becomes mixed up and very scared at night (delirium)

29 Problem behaviors Uncooperativeness
Combativeness with care or assistance Refusal of redirection Wandering Hitting and other violence Tearfulness Beseeching Yelling, profanity, verbal aggression Pacing Exit-seeking, trying the doors Hoarding of objects Repetitive behaviors Apathy, lack of motivation Social withdrawal

30 Common causes of disturbance
Delirium Medical problem UTI, pain, constipation, dehydration, other Medication Anticholinergics, benzodiazepines, opioids, lithium, anticonvulsants, slow increase in serum drug levels, Cognitive impairment Disorientation I.e., sundowning Frustration with functional deficits Unwilling to accept help Comprehension deficits Apraxia Mood or psychotic disorder Recurrence of prior illness Caused by AD 25-50% of demented persons have significant mood disorder Environment Wrong level of care Change in environment Disorientation Agnosia Unsophisticated care-giving Just as likely with paid staff as with family

31 Find the cause Due to general medical condition or medication (delirium)? Treat the cause Harder to stop medications than start them To start them you just need a bright idea To stop them you must monitor response and think (creatively) of possible adverse events Use supportive care Due to environmental stressor or precipitant? Modify the environment Educate caregivers

32 Find the cause (2) Closely linked to the cognitive impairment?
Avoid precipitants Intervene early during escalation Distraction and activity therapy Educate caregivers Due to difficulties in patient caregiver relationship or unsophisticated care? Evaluate, educate, support the caregiver Develop new routines, activities, structure Recurrence of a pre-morbid psychiatric illness?

33 Clinical examples 72 y.o. man who paces and asks to go home, everyday starting at about 4pm, while at home with his wife (“sundowning”) More disoriented as he becomes fatigued, less able to access intact cognitive skills May be related to disordered circadian rhythm May benefit from antidepressant or antipsychotic 87y.o. woman who becomes combative with whomever tries to help her take a bath in the nursing home (“care specific”) Individualized approach May simply consist of changing aides or time of care 69y.o. woman who barricades in her room and says others are stealing from her (“psychosis”) Treat delusions with antipsychotics when affectively charged 77y.o. man who refuses to eat or stop watching TV becomes angry and upset when asked to do otherwise (“depression”) Antidepressants (although efficacy not proven) Activity therapy Environmental changes 91y.o. woman who starts screaming every time she looks at herself in a mirror (“agnosia”) Tends to be seen in more advanced disease Start with environment change (remove mirror) 75y.o. woman who suddenly has trouble getting to sleep and becomes mixed up and very scared at night (“delirium”) The clue is time course (sudden change) Look hard for medical cause Start with medication review, labs

34 Common issues in dementia care (Dementia Care Needs Assessment)
Patient Caregiver Primary care! Safety measures Driving, wandering, falling, self harm Oversight of medication administration Daily structure Recreational activities Day care Behavioral program Highly individualized Play to individual’s strength and history Intact remote memory Hobbies Sleep and eating routines ? Cognitive rehabilitation Decision making Capacity evaluations Realistic expectation re disease and stage Skills training Respite Problem solving help Crisis availability Emotional support Slow pace of grief – different than death Treat depression Decision making Advance directives POA/guardianship When to change level of care When to give up 24/7 caregiving Caregiver support groups Access to experienced specialists

35 Common patient issues in dementia care (Dementia Care Needs Assessment)
Primary care Safety measures Driving, wandering, falling, self harm Oversight of medication administration Daily structure Recreational activities Day care Friends Retained skills Sleep and eating routines Decision making Capacity evaluation Behavioral programs Highly individualized Play to individual’s strengths and history Often utilizes intact remote and procedural memory Hobbies Therapeutic Activity Plan (TAP) Laura Gitlin, JHU Familiar tasks Housekeeping Home maintenance

36 Symptom constellation of dAD Comparison with major depression
More common Less common Anhedonia Depressed mood Anxiety Guilt Irritability Hopelessness Lack of motivation Suicidality Agitation Delusions Hallucinations

37 Treatment of depression in Alzheimer’s Disease
Prior to 2003, antidepressant studies split about between positive and null effect of medication Depression of Alzheimer’s Disease (DIADS) Johns Hopkins RCT of sertraline for major depressive episode in AD (N=44) 12-week trial Achieved dose close to 100 mg daily Better mood and functional outcomes with sertraline

38 Treatment of apathy in AD
Loss of motivation, initiative, and interest Can be distinguished from depression Major quality-of-life issue for caregivers May be related to deficient dopaminergic neurotransmission ADMET 6 week RCT of methylphenidate 20 mg daily (divided doses) in 60 AD patients with apathy Significant improvement in 2 of 3 outcomes Rosenberg et al., 2012 Also trend toward improved attention (digit span) Well tolerated ADMET-2 More robust 6-month RCT with larger N (200), more sites (10), and more thorough cognitive assessment Currently recruiting

39 Safety and Efficacy of Methylphenidate for Apathy
in Alzheimer’s Disease: A Randomized, Placebo-Controlled Trial Paul B. Rosenberg, MD; Krista L. Lanctôt, PhD; Lea T. Drye, PhD; Nathan Herrmann, MD; Roberta W. Scherer, PhD; David L. Bachman, MD; and Jacobo E. Mintzer, MD, MBA, for the ADMET investigators J Clin Psych 2013;74: 6-week RCT of methylphenidate for apathy in AD Target dose 10 mg breakfast and lunch Most patients tolerated this dose

40 Treatment of agitation and psychosis in AD
Are medications needed? (often not) Severity of agitation/affective component Caregiver stress Interference with daily care Target symptoms Specific agitated behaviors Affective component of delusions

41 Medications for agitation and psychosis in AD
Antidepressants Suggestion of efficacy for citalopram CITAD – NIH-funded trial of citalopram for agitation in AD (RECRUITMENT ONGOING) Antipsychotics Atypicals are best tolerated Risperidone (start 0.25 mg) Olanzapine (start 2.5 mg) Seroquel (start 25 mg) Abilify, Geodon , Invega used rarely Anticonvulsants Depakote Trileptal Similar to Tegretol but adverse events less common Avoid benzodiazepines except for emergencies

42 Antipsychotics and mortality in dementia
Small but significantly increased mortality in elderly demented patients 50% increase in mortality in 8-12 week trials Likely applies to typical as well as atypical agents Increase from 2 to 3% mortality, for example Depending on age and medical comorbidity Need to balance this small risk against benefit Quality of life/comfort care issues This is important to discuss with families! Caution in prescribing and in dosing Try to taper patients off antipsychotics once they are stable Lancet article 1/09 RCT of antipsychotic discontinuation in demented nursing home patients Little difference seen in 12-month trial But mortality higher in medicated group after blinded trial ended Equivocal result But suggest utility of discontinuation

43 SSRIs for agitation in AD Citalopram (CitAD trial)
SSRIs appear inherently safer than antipsychotics no mortality signal worry about prolonged QT intervals (FDA caution on citalopram) Citalopram for agitation in AD trial (CitAD trial) 9-week RCT of citalopram 30 mg daily N=188 at 8 academic medical centers in North America MMSE 10-26, no antipsychotics allowed Primary outcomes Neurobehavioral Rating Scale + Clinical Global Impression

44

45 Nuedexta Dextromethorphan/quinidine
involuntary and uncontrollable expressed emotion that is exaggerated and inappropriate, and also incongruent with the underlying emotional state. Avanir developed dextromethorphan/quinidine combination for PBA (Nuedexta) Tiny quinidine dose (10 mg) inhibits dextromethorphan catabolism, raising blood and brain levels fold Reasonable results for narrow indication Alzheimer’s with agitation phase II trial 220 participants two-stage Bayesian design Significant superiority over placebo in both stages There is a new variant which is deuterated and has lower quinidine dose

46 Pimavanserin 5HT2A inverse agonist
Targeting antipsychotic efficacy without EPS No dopaminergic antagonism. “The good half” of atypical antipsychotic mechanism Phase III trial for psychosis in Parkinson’s disease (PD) 199 participants randomized for 6-week RCT Psychosis decreased with significant superiority over placebo No worsening of motor function Most discontinuation was due to VH (i.e., didn’t work for psychosis in some patients) Now being studied in AD phase III trial I think target symptom is agitation not psychosis There is a similar drug with great results in early phase schizophrenia trials

47 Treatment of insomnia in AD
Behavioral Medications Sleep hygiene Calm, quiet, dark environment Minimize caffeine Daytime exercise Minimize naps (if extreme) Daily nap is normal Look for medical cause Antipsychotics if “sundowning” and agitation associated with insomnia Trazodone mg Mirtazapine (Remeron) mg
