    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.
