Problems Experienced in Late Life : polypharmacy

A

*Polypharmacy: Prescribing multiple drugs to a person
40% of elderly persons are prescribed at least 5 medications
Increases the risk of adverse drug reactions
Most researchers test drugs on younger people

Q

Research Designs

A
  • Cross-sectional studies
  • Researcher compares different age groups at the same point in time on a variable of interest
  • Fails to provide information about how people change over time

*Longitudinal studies
Researcher retests the same group of people with the same measures at different points in time
May extend over several years or decades
Attrition can lead to biased sample
Selective mortality – no longer available for follow-up because of death
People with the most problems are likely to drop out from a study

Q

Psychological Disorders in Late Life

A

DSM criteria are the same for older and younger adults

Particularly important to rule out medical explanations
Medical problems can also worsen the course of depression
Age-related deterioration in the vestibular system can account for panic symptoms
Depression is common after strokes or heart attacks
Antihypertensive medication, corticosteroids, and anti-parkinson medications may contribute to depression or anxiety
Disentangling medical and psychological concerns is complex!

Q

Methodological Issues

A

Response bias
Discomfort discussing symptoms may minimize prevalence estimates

Cohort effects
E.g., many people who reached adulthood during the drug-oriented era of the 1960s continue to use drugs as they age

Selective mortality
Psychological disorders are associated with premature mortality

Q

Mild Cognitive Impairment

A

Early signs of decline before functional impairment

Problems with DSM-5 criteria requiring a low score on only one cognitive test
Some cognitive test are more reliable and relevant than others
Using more than one test improves reliability
10% of the time, cognitive declines are tied to other problems
Infection, sleep loss, thyroid disease, vitamin deficiencies
Current MCI criteria may not be very reliable
Could lead to over-diagnosis

Not all people with MCI develop dementia

Q

DSM-5 Criteria: Mild Neurocognitive Disorder (Mild Cognitive Impairment

A

Modest cognitive decline from previous levels in one or more domains based on both of the following:

  • Concerns of the patient, a close other, or a clinician
  • Modest neurocognitive decline (i.e., between the 3rd and 16th percentile) on formal testing or equivalent clinical evaluation
  • The cognitive deficits do not interfere with independence in everyday activities (e.g., paying bills or managing medications), even though greater effort, compensatory strategies, or accommodation may be required to maintain independence

The cognitive deficits do not occur exclusively in the context of delirium and are not due to another psychological disorder

Q

Alzheimer’s Disease

A

Irreversible brain tissue deterioration

Usually begins with:
Absentmindedness and gaps in memory for new material
Leaving tasks unfinished or forgotten
Difficulty finding words

Other symptoms
Apathy, depression, disorientation
As brain deterioration progresses, the severity of symptoms increase
At first, people are often unaware of their cognitive problems
Progresses to oblivious awareness of surroundings

Q

Brain Changes in Alzheimer’s Disease

A 
Plaques: β-amyloid protein deposits
Primarily found in frontal cortex
Neurofibrillary tangles: Protein filaments composed of tau
Primarily found in hippocampus
Measured using PET scans

Immune responses to plaques lead to inflammation
-Loss of synapses and neuronal death

Q

Frontotemporal Dementia

A

Loss of neurons in frontal and temporal lobes
Typically begins in late 50s, progressing rapidly
Death usually occurs within 5 years
Affects less than 1% of the population

Most common subtype: behavioral variant
Deterioration in at least 3 areas:
Empathy, executive function, ability to inhibit behavior, compulsive or perseverative behavior, tendencies to put nonfood in mouth, apathy
Strikes emotional processes more profoundly than Alzheimer’s
Often misdiagnosed
E.g., midlife crisis, bipolar disorder, depression

A

Caused by cerebrovascular disease

25
Q

Dementia with Lewy Bodies

A
  • Protein deposits (Lewy bodies) form in the brain and cause cognitive decline

26
Q

  • Study people with early biological markers
  • Prevent development of plaques and tangles
27
Q

Treatment of Dementia: Psychological Treatments

A

*Supportive psychotherapy
Education about disease and care for patient and family

*behavioral approaches
External memory aids
Music to reduce agitation and disruptive behavior
Psychotherapy to reduce depression
Increasing pleasant and engaging activities

  • Exercise and cognitive training to prevent cognitive decline before it begins
  • Small benefit of training in individuals with mild cognitive impairment
28
Q

signs of delirium

A 
Clouded state of consciousness: 
Extreme trouble focusing attention
Cannot maintain a coherent stream of thought
Trouble answering questions
Disturbances in the sleep/wake cycle
Drowsy during the day, yet awake and agitated at night

Difficult to engage in a conversation 
Speech may become rambling and incoherent 
Disorientation of time, place, and name

29
Q

DSM Criteria: Delirium

A

Disturbance in attention and awareness
A change in cognition not better accounted for by a dementia
E.g., disturbance in orientation, language, memory, perception, or visuospatial ability
Rapid onset (usually within hours or days) and fluctuation during the course of a day
Symptoms are caused by a medical condition, substance intoxication or withdrawal, or toxin

30
Q

Delirium

A

Rapid onset and can fluctuate during the course of a day
Lucid intervals where person becomes alert and coherent
Daily fluctuations help distinguish delirium from other syndromes, especially Alzheimer’s disease

Can occur at any age
Common in children and in older adults
Often misdiagnosed
Untreated, the mortality rate for delirium is high
Predictor of death within the next six months
Increased risk of further cognitive decline

31
Q

Treatment of Delirium

A

Complete recovery if underlying cause is treated
Atypical antipsychotic medications are also used
Usually takes 1 to 4 weeks to clear
Takes longer in older people than younger people
Reduce risk factors for delirium within the hospital setting:
Sleep deprivation, immobility, dehydration, visual and hearing impairment

Family should learn about delirium symptoms and its reversible nature to avoid interpreting the onset of delirium as a new stage of a progressive dementia
