The 3 Ds of Geriatric Care Depression, Dementia and Delirium
Dementia • Average delay from 1st symptom to diagnosis 2-3 years. • Family recognition is usually how it gets diagnosed. Caregiver complaints, high suspicion of dementia • Post CVA (30% develop within 3 months) • Post-delirium (30% develop within 3 years) • Post first onset depression (30% develop within 3 years) • Family history – every first degree relative • Age (2% at age 65) Every five years doubles risk of dementia • Every vascular burden/risk factor doubles the risk
Dementia Risk calculator Age • 65 2% • 70 4% • 75 8% • 80 16% • 85 32%
Dementia Quick Screen • Say three words, repeat back • 1 minute to name as many 4 legged animals (20 times odd ratio) If Animals are low – Alzheimer’s • List year (37 times odds ratio) • Draw clock 10 after 11 o’clock (24 times odd ratio) Specificity 94% Large enough circle, joined Numbers evenly spaced Time correct – hand placement • Remember and repeat the three words from the beginning
MMSE Gold standard • Needed for prescribing of cholinesterase inhibitors • <26 is dementia • Not sensitive for mild cognitive impairment • Deceptive: low educational/economic status, poor language, illiteracy, impaired vision • Scoring: 27-30 Normal 20-26 Mild AD – Independent (advance care planning) 10-19 Moderate AD – Supervision <10 Severe AD - Total dependence
MoCA • Meant to assess mild cognitive impairment (score <26) • Clock draw – visual spatial and executive function • Rhino becomes a hippo • Lewy Bodies – attention deficit present • Less than 11 f words – • frontal or vascular dementia – will see inappropriate words come up first
Peterson Criteria: Diagnosing MCI • Memory complaint • Memory impairment for age and education • Largely intact general cognitive function • Present ADLs – no functional loss. • Not demented
Diagnosing AD • Memory impairment • Impairment in function • One of • Aphasia (language) • Apraxia (motor) • Agnosia (recognition, identification) • Disturbance in executive function (planning organizing) • Significant decline from previous level of function • Impairment in social or occupational functioning • Gradual onset – sudden onset is delirium until proven otherwise • Not due to other causes.
Delirium • Commonly under-diagnosed, particularly in residents who have a pre-existing dementia. • Acute and fluctuating onset • Medical emergency • Confusion, disturbances in attention, disorganized thinking and/or decline in level of consciousness
CAM Confusion Assessment Method – Delirium Sensitivity 94-100%, Specificity 90-95% 20% deliriums never clear • Acute onset and fluctuating course • Inattention • Disorganized thinking • Altered level of consciousness • Diagnoses required the presences of features of 1 and 2 and either 3 or 4.
Meet Mrs. G. • Pneumonia, treated 1 month ago. • Productive cough • Calling out, worse in evening. Staff reports that behaviours are most challenging between 3pm and 7pm. Staff refer to it as “Sundowning”. • Worries about her son, recognizes him but no longer knows he is her son. Worried about having to pay for being in the LTC home.
Mrs. G. • Lethargy – change in sleep pattern that is worse over the last week. Sleeping more in the morning and wakes up around 3pm. • Recently moved to LTC from hospital (1 month). Prior to that was living at home. • Falls in hospital and 2 at the LTC home since admission.
PMHx Bilateral glaucoma Mild hearing loss Depression & anxiety Alzheimer’s Disease Past history of delirium Past history of LRIs and UTIs Hypothyroidism Hypotension COPD Graves Disease Osteoporosis Osteoarthritis Past smoker (quit 5 years ago) Left hip fracture and bilateral wrist fractures Bilateral leg edema Bowel resection, prone to constipation - malignant polyps
Recent Diagnostics • TSH 14.87 From admission bloodwork drawn but not yet reviewed. • CXR 2 days ago is negative for active process
Medications • Lasix 20mg PO daily • Xalatan and Timolol gtts • L-Thyroxine 0.15mg PO daily • Celexa 40mg PO daily (recently decreased from 60mg) • Spiriva and short acting PRN bronchodilator for COPD • Seroquel 50mg PO BID at 0800 and 2000 • Clonazepam 0.5mg PO at 0800 and 1200; 2mg PO at 1600 and 2mg PO once daily PRN • Colace QHS • Lactulose PRN • Tylenol PRN (PO or PR) Had tried Aricept in the past but did not tolerate it.
Neuro Ax • Difficult to rouse, sternal rub required to rouse Mrs. G. Speech slurred and difficult to understand. Family states that this is new and unusual for her. Able to converse for 3-4 minutes before falling back asleep. Able to follow directions but shows inattention. Bilateral grip equal. Unable to assess pupils d/t glaucoma. • CAM score + for delirium (Feature 1, 2 and 4 present)
Resp Ax • RRR, 16. No wheezing. Fine bilateral rales audible. No SOB. Congested cough, w upper airway secretions. Afebrile.
CV Ax • No murmurs, HR 76, S1, S2. No peripheral edema noted. Recent BP readings by staff stable.
Integument Ax • Very dry skin. Mucous membranes dry. Bruising present to lower legs.
GU Ax • No specific signs of UTI. Small temp change from baseline T 37.0 (baseline 36.2). • Chronically positive C&S
Abdominal Ax • BS present x 4 quadrants. No rebound tenderness noted. Resident up in W/C, therefore not assessed fully. Voiding well into brief. No reports of dysuria, frq, urgency, changes in continence. T 37.0 (baseline 36.2). Recent bowel movements have been regular and soft/formed in consistency.
Pain Ax • Vague self-report. Behavioural indicators of pain in staff reports. Kyphotic in appearance. Recent loss of mobility (past 6 months). Family reports that she used to be on regular Tylenol in the retirement home but this was discontinued in hospital. Family reports that Mrs. A would never be one to ask for help with pain. Recent falls. No spinal x-rays taken. Is not on Vit D or Calcium.
Impression? Delirium co-existing w dementia and depression! Risk Factors: Age, CI, Hx delirium, Hx depression, sleep disturbance, vision and hearing loss, recent relocation, hx fractures, unrelieved pain, hypotension, recent infection, polypharmacy, benzodiazepine use, antidepressant use, antipsychotic use.
Now What? What is causing her delirium? Differentials: • Dehydration • Pain • Hypothyroidism • Polypharmacy
Other Considerations • High risk of fractures, affecting QOL. Spinal x-ray not feasible for her. Recent falls and posture combined with behaviours make vertebral fractures highly likely. • Prob UTI at this point seems low given the non-specific nature of her symptoms. Will always test positive – no need to treat unless symptomatic. • Recent CXR negative. Rales could be some residual post-infection atalectasis.
What’s our plan? • Increase L-Thyroxine and recheck TSH in 1 week • Discontinue PRN Tylenol • Tylenol 325mg 2 tablets (total 650mg) PO QID x 2 weeks then reassess. She is opiate naïve – if we want to try these go low and slow • Encourage oral fluids. • Dietitian to assess re: fluid intake. • Vitamin D 1000iu PO daily • Taper Clonazepam slowly.
Depression vs. Dementia or Depression with Dementia • For the most part, these two conditions coexist. Depression looks different in older adults. • Feelings of guilt/worthlessness • Hopelessness, death wishes, suicidal • Frequent crying spells • Resident overstates impairments • Greater problems with attention, concentration, speed of processing and retrieval • Constructional apraxia, agnosia and aphasia are rare • Usually performs well on memory tasks
