Study Notes

Cognitive Assessment

AD8 (Eight-item Informant Interview to Differentiate Aging and Dementia) is a sensitive, informant-based test that accurately determines if a person has dementia or not
Mini-mental state examination (MMSE) is historically the most commonly used cognitive test
Montreal Cognitive Assessment (MoCA) was developed in 2005 and includes the evaluation of additional domains, such as visuospatial ability and executive function
Addenbrooke's Cognitive Examination III (ACE-III) is a thorough screening tool that takes around 20 minutes to complete and offers a high degree of diagnostic accuracy in cases of subjective cognitive decline and mild cognitive impairment

Neuroimaging in Dementia

Neuroimaging is a crucial part of the diagnosis process for those who are suspected of having dementia
Computed tomography (CT) or magnetic resonance imaging (MRI) scans can rule out potentially treatable causes of cognitive impairment, such as brain tumors, subdural hematomas, and normal pressure hydrocephalus
Global cortical atrophy (GCA) is a four-step scale to measure atrophy, ranging from 0 (no atrophy) to 3 (knife-blade atrophy)
Medial temporal lobe atrophy (MTA) represents the loss of volume in the hippocampal area and is sensitive for Alzheimer's disease
White matter changes and large areas of disease in the white matter of the brain are associated with cognitive decline and dementia
Microbleeds are tiny areas of focal intracerebral hemorrhage visible on susceptibility-weighted MRI sequences, often caused by cerebral amyloid angiopathy or hypertension

Dementia Diagnosis

The National Institute of Neurological Disorders and Stroke (NINDS-AIREN) criteria are used to diagnose vascular dementia
Alzheimer's disease is characterized by cortical atrophy, particularly in the parietal and temporal lobes, with hippocampal atrophy a symptom of late-onset Alzheimer's disease
Vascular dementia manifests as small- and large-vessel disease, resulting in confluent white matter alterations, lacunar infarcts, and/or postischemic cortical/subcortical cerebrovascular lesions
Frontotemporal dementia comprises three subtypes: behavioral, progressive non-fluent aphasia, and semantic
Mixed dementia has no specific findings and may have variable degrees of atrophy and small vessel disease

Management of Older People with Dementia

The goals of management are to reduce suffering caused by cognitive decline and related symptoms, and to slow down the progressive loss of cognitive function
Non-pharmacologic approaches, such as cognitive training, physical exercise, social interactions, and music therapy, can keep the mind and body healthy
Pharmacologic interventions, including cholinesterase inhibitors and memantine, can provide symptomatic benefits for cognitive symptoms
Emerging disease-modifying therapies, such as anti-amyloid immunotherapies, have shown promise in slowing the rate of cognitive impairment in patients with mild Alzheimer's dementia

Case Study

Gabriella, a 73-year-old retired teacher, is suspected of having dementia due to her anxiety on the bus, crying, and anger
A medical history, neurological and cognitive assessment, and neuroimaging are used to arrive at a diagnosis
The goals of management are to reduce suffering caused by cognitive and related symptoms, and to slow down the progressive loss of cognitive function### Dementia Diagnosis and Support
The consultation should start with the patient, and family members or friends should be brought in only if the patient agrees.
In most cases, the diagnosis should be disclosed clearly and directly, avoiding euphemisms.
Patients who prefer not to be told should be respected, and disclosure should be handled carefully or deferred in cases of anosognosia.
The diagnosis should be followed by a plan for managing the disease.

SPIKES Protocol for Delivering Bad News

S - Setting: Choose a private and quiet location for the consultation, ensuring minimal interruptions.
P - Perspective: Assess the patient's knowledge and concerns about their illness.
I - Invitation: Determine how much information the patient wants to know about their condition.
K - Knowledge: Provide clear and straightforward information about the diagnosis, using simple language.
E - Empathy: Exhibit empathy and support while sharing the diagnosis, acknowledging the patient's emotions.
S - Summary: Summarize the key points and offer support, emphasizing the patient's care team.

Post-Diagnostic Support

The primary goal of post-diagnostic support is to enable people with dementia to live well in the community.
Post-diagnostic support services should provide information, social engagement, and peer support to reduce anxiety and loneliness.
Family members of people with dementia should also receive education and support.
The Scottish 5-pillar model for post-diagnostic support emphasizes individualized and localized support.
Post-diagnostic support should be tailored to the patient's changing needs, ensuring consistency and full integration into the care system.

Reducing Risk of Dementia

Risk factors at different stages of life can contribute to an increased risk of brain health issues and dementia.
Lifestyle changes that can reduce the risk of dementia include:
- Keeping physically active
- Eating healthily
- Not smoking
- Drinking less alcohol
- Staying mentally and socially active
- Taking control of health
- Getting enough sleep
- Protecting hearing and head
The Australian National University Alzheimer's Disease Risk Index tool (ANU-ADRI) can measure a person's exposure to risk factors.

Caregiver Support and Burden

Caregiver burden is a significant predictor of bad outcomes from home care.
Tools such as the Zarit Burden Interview-Short Form (ZBI-12) and the Caregiver Strain Index (CSI) can measure caregiver burden.
Assessing caregiver burden is crucial to identify households where caring may be a concern.
Support services should prioritize caregiver education and training, as well as cognitive stimulation for people with dementia.
