sundowning definition
Sundowning: Definition
  • Sundowning  a group of behaviors occurring in some older patients with or without dementia at the time of nightfall or sunset.
  • BEHAVIORS:
    • Confusion
    • Anxiety, agitation, or aggressiveness
    • Psychomotor agitation (pacing, wandering)
    • Disruptive, resistance to redirection
    • Increased verbal activity
  • Overlap with dementia, delirium, and sleep disturbance.
epidemiology of sundowning syndrome
Epidemiology of Sundowning Syndrome
  • Not uncommon phenomenon
  • Exact prevalence unknown
  • Reports have ranged between 2.4% and 25%
    • In patients with Alzheimer’s disease or dementia, the range is widened up to 66%
risk factors for sundowning physiologic factors
Risk Factors for Sundowning: Physiologic Factors
  • Circadian abnormalities in elderly and in patients with Alzheimer’s disease progress concomitantly with their behavioral and cognitive dysfunction.
    • Sundowning is more common in AzD.
      • Neurofibrillary tangles found in the hypothalamus of patients with Alzheimer’s may lead to the behavioral changes of sundowning through mechanical disruption of brain tissue.
      • Pathologic damage to the suprachiasmatic nucleus (SCN) is believed to result in disruptive behaviors associated with sundowning.
risk factors for sundowning environmental factors
Amount of daily light exposure

Activities during the day

Noise level

Disruptions at night

Medications

Medical comorbidities

Nursing home residents with sundowning were more likely to

Recent admission

Moved to a new room

Staff shift changes

Low levels of lighting during the day and bright hallway lighting during the night

Increased naptime during daytime hours and reduced nighttime sleep

Risk Factors for Sundowning: Environmental Factors
etiology of sundowning
Etiology of Sundowning
  • Dysfunction of the circadian rhythm result in disturbed sleep and agitation
    • Deterioration of the SCN seen in patients with Alzheimer’s disease is actively investigated to be an important factor in the disruption of the circadian rhythms.
    • Suprachiasmatic nucleus volume and cell number are found to be decreased in those between the ages of 80 and 100 years.
    • Melatonin is found to be decreased in the cerebrospinal fluid levels of patients with Alzheimer’s disease.
mrs flabeetz
Mrs. Flabeetz
  • 84 yo female, living at the NH for the last 8 years after a stroke; was having problems managing at home
  • Axis III: Type II Diabetes and hypertension
  • Active in her NH, using her walker; also a little more forgetful and repetitive, and this has been getting slowly worse over the last year
in the er
In the ER…
  • Came into ER after being found on the floor of the NH
  • Unable to get up and complaining of L hip and abdominal pain
  • In the ER, very muddled up & disoriented
  • incontinent of foul smelling urine
  • Picking at imaginary things, scared, and very frightened
initial work up
Initial work up…
  • No fracture on X-ray
  • Normal CBC, lytes and troponins
  • CT head shows mild atrophy & bilateral lacunar infarcts
  • Urine collected from foley inserted shows E. coli; started ABX
  • Admitted to Medicine for further assessment and work up of confusion

Alas! It’s been 5 days later, and she’s still not better …

TRANSFER TO PSYCHIATRY!!!!!!!

What would you do?

Is this Delirium? Dementia??

Or something else???

Would you transfer to Psychiatry Service?

delirium
Delirium
  • Most common psychiatric disorder in the medically ill
  • Point prevalence - 20% of all admissions
    • 30% new onset among medical inpatients
    • 50% medical and surgical patients > 60 yo
    • 89% of patients with known dementia
  • Higher prevalence with increasing age, CNS disease, CABG, and THR
  • NOT a benign condition - sign of impending death in 25% cases
  • Etiology - multifactorial

Rothschild et al, Arch Int Med 2000; Burns et al, JNNP 2004

diagnostic criteria dsm iv
Diagnostic Criteria: DSM-IV
  • Disturbance of consciousness (reduced clarity of awareness of environment)
    • Reduced ability to focus, sustain or shift attention
  • A change in cognition (memory, disorientation, language disturbance) or the development of a perceptual disturbance that is not better accounted by dementia
diagnostic criteria dsm iv14
Diagnostic Criteria: DSM-IV
  • The disturbance develops over a short period of time (usually hours to days)
  • All abnormalities tend to fluctuate during the course of the day
diagnostic criteria dsm iv15
Diagnostic Criteria: DSM-IV
  • There is evidence from the medical history, physical examination, or laboratory findings of:
      • A general medical condition etiologically related
        • Sepsis, seizures, tumor, hypercalcemia, hypoglycemia
      • Substance induced intoxication or withdrawal
      • More than one etiology
      • NOS
motoric subtypes
“Motoric” Subtypes

Various levels of psychomotor activity

are associated with delirium:

  • Hypoactive
  • Hyperactive
  • Mixed
motoric subtypes18
“Motoric” Subtypes
  • Subtyping not fully accepted by all disciplines
  • Subtyping may have implications for treatment
epidemiology risk factors
Epidemiology & Risk Factors
  • Depending on the cohort, the prevalence of delirium ranges from 8% to 80%
    • Post-surgical rates > general medical patients
    • Advancing age increases the risk (> 60 yoa)
  • 15-20% of patients on a medical surgical ward have an undetected delirious process

Burns et al, JNNP 2004; Kales et al, JNNP 2002; vanZyl & Davidson, Can J Psych 2003

epidemiology and risk factors
Epidemiology and Risk Factors
  • The Commonwealth-Harvard Study (Levekoff et al., Int Psychoger, 1991)
    • Patients 65 yoa or older
    • Admissions to Beth Israel Hospital from Hebrew Rehabilitation Center (n=114) and East Boston CHC (n=211)
      • CHC  24.2% were delirious
      • HRC  64.9% were delirious
epidemiology and risk factors21
Epidemiology and Risk Factors
  • CNS abnormality
    • Dementia, coexisting structural brain disease, and HIV-1 infection increase the risk
  • Drug dependency
    • Alcohol, sedative hypnotics, stimulants, steroid (rapid taper) increase the risk
  • Low serum albumin
    • Malnutrition, chronic disease, aging, nephrotic syndrome, hepatic insufficiency
why is delirium important
Why is Delirium important?

Delirium has a poor prognosis

  • Ý LOS (>7d more)
  • Ý risk dementia dx (55%/2y)
  • Ý ADL decline
  • Ý institutionalization
  • Ý mortality (2.1x/12 mos)

diagnosis mse
Diagnosis: MSE
  • Mental status examination
    • Cognitive history  chart review
      • What changes (consciousness, restlessness, anxiety, moodiness)
      • When did changes occur (starting/stopping drug, fever, hypotension, deteriorating renal function, rhythm changes)
    • MMSE, focused NBE
diagnosis testing standard
Diagnosis Testing - Standard
  • MMSE & CDT
    • -Not designed for delirium
    • -Useful at separating “normal” from “abnormal”
    • -Not specific for distinguishing delirium from dementia
    • -May be useful as change from baseline
    • -Overkill  add TMT-A, TMT-B

1. [Acute Onset] Is there evidence of an acute change in mental status from the patient\'s baseline?

2A. [Inattention] Did the patient have difficulty focusing attention, for example, being easily distractible, or having difficulty keeping track of what was being said?

2B. (If present or abnormal) Did this behavior fluctuate during the interview, that is, tend to come and go or increase and decrease in severity?

3. [Disorganized thinking] Was the patient\'s thinking disorganized or incoherent, such as rambling or irrelevant conversation, unclear or illogical flow of ideas, or unpredictable switching from subject to subject?

4. [Altered level of consciousness] Overall, how would you rate this patient\'s level of consciousness? (Alert [normal]; Vigilant [hyperalert, overly sensitive to environmental stimuli, startled very easily], Lethargic [drowsy, easily aroused]; Stupor [difficult to arouse]; Coma; [unarousable]; Uncertain)

5. [Disorientation] Was the patient disoriented at any time during the interview, such as thinking that he or she was somewhere other than the hospital, using the wrong bed, or misjudging the time of day?

6. [Memory impairment] Did the patient demonstrate any memory problems during the interview, such as inability to remember events in the hospital or difficulty remembering instructions?

7. [Perceptual disturbances] Did the patient have any evidence of perceptual disturbances, for example, hallucinations, illusions or misinterpretations (such as thinking something was moving when it was not)?

8A. [Psychomotor agitation] At any time during the interview did the patient have an unusually increased level of motor activity such as restlessness, picking at bedclothes, tapping fingers or making frequent sudden changes of position?

8B. [Psychomotor retardation]. At any time during the interview did the patient have an unusually decreased level of motor activity such as sluggishness, staring into space, staying in one position for a long time or moving very slowly?

9. [Altered sleep-wake cycle]. Did the patient have evidence of disturbance of the sleep-wake cycle, such as excessive daytime sleepiness with insomnia at night?

diagnostic testing eeg
Diagnostic Testing: EEG
  • Diffuse slowing
    • Most helpful to get a baseline
      • Patients with AzD may have abnormally slowed EEG
        • Worsens from baseline with delirium
      • Patients with minimal slowing may have test read as “normal”
        • Alpha (13 cps) may slow down (9 cps) and still be in normal range
        • Comparison with baseline
        • Comparison with repeat EEG post delirium

dementia and delirium
Dementia and Delirium
  • Dementia is a risk factor for delirium
  • Diagnosis of delirium in context of dementia is often missed
    • Of 2000 consecutive admissions:
      • 9.1% of patients had diagnosis of dementia
      • 41.4% of these demented patients had delirious process on admission

risks of using v not using atypical antipsychotics
Risks of Using v Not Using Atypical Antipsychotics
  • Increased mortality in elderly patients with dementia-related psychosis
    • 17 placebo controlled trials
    • Modal duration of 10 weeks
    • Risk of death in treated patients 1.7 times that seen in placebo treated patients
    • Varied cause
      • CV (HF, sudden death)
      • Infectious
final verdict
Final Verdict
  • Atypical antipsychotics are not approved for the treatment of patients with dementia-related psychosis
  • FDA stated “The agency is not advising against all off-label use of atypicals, but is reminding the public that these drugs are not approved fro treating dementia and is advising patients treated with these drugs to have their treatment plans reviewed”.
