ACE III Flashcards
(32 cards)
what does the ACE-III examine
cognitive function
what does cognition mean
mental abilities (memory, attention, language, perception, problem solving)
what are cognitive functions
they enable us to learn and remember, concentrate, communicate, understand, carry out everyday actions and solve problems.
what is cognitive impairment
when an individual has trouble with abilities such as remembering, learning new things, concentrating, solving problems or making decisions that affect everyday life.
describe the difference between mild and severe impairment
Mild impairment- individuals may begin to notice changes in their mental abilities (e.g difficulty remembering a conversation, concentrating on a book, word finding problems, difficulties cooking, using money), but STILL CAN COMPLETE EVERYDAY ACTIVITITES. Severe impairment can lead to losing the ability to remember things, to recognise people, places or objects, to talk or write, and to carry out basic actions, resulting in the INABILITY TO LIVE INDEPENDENTLY
name some causes of cognitive impairment
Alzheimer’s disease
Vascular conditions (e.g stroke, vascular dementia, multi-infarct dementia)
Fronto-temporal lobe dementias
Lewy Body dementia
Parkinson’s disease
Huntington’s disease
Progressive Supranuclear Palsy
Multiple sclerosis
Traumatic brain injury
Normal pressure hydrocephalus
Toxic conditions (e.g. alcohol related conditions, effects of street drugs and social drugs, environmental and industrial neurotoxins)
Infectious processes (e.g. HIV infection and AIDS, Lyme disease, Chronic fatigue syndrome, Herpes simplex encephalitis)
Brain tumours
Oxygen deprivation (e.g. following heart attack, carbon monoxide poisoning)
Metabolic and Endocrine disorders (e.g. hypothyroidism and liver disease)
Nutritional deficiencies (e.g. Vitamin B12 deficiency)
Prescribed Medication
Mood problems (e.g. stress, anxiety, depression)
Psychiatric problems (e.g. psychosis)
Delirium
Infections (e.g. chest infection and urinary tract infection)
Intellectual disabilities
Pain and discomfort
what is static cognitive impairment
when the cognitive impairment will remain constant, compared to degenerative
can cognition be affected by emotional difficulties
yes- eg. depression, anxiety
what are some possible causes of cognitive impairment
Medication
Alcohol/drugs- not reliable assessment
pain
head injury
learning disability
mood
what is the commonest cause of dementia and describe it
Alzheimer’s disease
memory problems, a progressive deterioration in the ability to perform ADL, and behaviour changes, mainly apathy and social withdrawal, but also behavioural disturbances. Cognitive difficulties vary between individuals, and worsen as the disease progresses.
how does vascular dementia affect cognition
Damage to the network of vessels in the brain can result in loss of oxygen supply to the brain and associated brain damage / cognitive problems
A common problem is narrowing of the vessels due to build up of deposits on the vessel walls. This would have a gradual effect on some aspects of cognition. Typically, memory and speed of processing are affected. The problems tend to get worse, especially if risk factors such as high blood pressure or high levels of cholesterol go untreated.
Common physical problems include urinary incontinence, decreased mobility and balance problems (more common that AD.
what are characteristic features of dementia with lewy bodies
fluctuation of awareness from day-to-day and signs of parkinsonism such as tremor, rigidity and slowness of movement, or poverty of expression. Visual hallucinations or delusions occur frequently. Falls are also common. DLB is associated with progressive cognitive decline and parkinsonism.
what is frontotemporal dementia and how does it present
primarily cause problems with behaviour and/or language.
typically changes in behaviour such as disinhibition, lack of judgement, loss of social awareness and loss of insight.
In temporal variant FTD - now termed Primary Progressive Aphasia (PPA), people develop language problems including loss of knowledge of words, objects and/or people.
what are different type of Primary Progressive Aphasia (PPA) also known as frontotemporal dementia
Semantic Dementia
Progressive Non-fluent Aphasia (PNFA)
Logopenic Progressive Aphasia (LPA)
what is mixed dementias
mixtures of two or more active dementias (one or more may be dominating)
is the ACE-III sensitive to the early stages of dementia
yes
cognitive screening tool
what are the 5 subscales of ACE-III
attention
language
fluency
memory
visuospatial
what is the overall score of ACE-III
and the overall score of mini-ACE
100
30 (shorter, only takes 5 minutes, if administration of ACE-III is not practical)
is the ace a diagnostic tool
no
why use the ace
Standardised and reliable
Sensitive to early stages of Alzheimer’s disease
The memory tests reflect the importance of episodic memory characteristic of early Alzheimer’s Disease
Assesses memory recognition and verbal fluency, assisting differential diagnosis
Provides subscale scores for each cognitive domain it assesses
Cognitive screening tools offer a time-efficient, objective initial assessment of cognitive functioning
The ACE-III has been found to be reliable and valid in the assessment of dementia.
when should you use the ACE
if over 50 and present with suspected cognitive impairment
when should you not use the ACE
known learning disability
if sedated
delirious/ hallucinations
distressed about completing the test
if no consent
not sufficiently fluent in English
what should you do if using a translator
Always meet with the interpreter before patient
Never allow the interpreter to translate items ‘in the moment’
The interpreter should translate test instructions
Instruct the interpreter not to give any additional assistance during testing
Encourage the interpreter to let the clinician know immediately if they feel something has been misunderstood by the patient
Encourage the interpreter to reflect on their personal knowledge of the cultural background the patient is from e.g. education systems in original country
Encourage the interpreter to inform you if a word or phrase does not translate
Encourage the interpreter to inform you if they don’t know the translation – it’s ok!
Encourage the interpreter to disclose any issues that may be important e.g. do they know the patient? Conflicts of interest? Relevant personal difficulties?
Consider using the interpreter when providing feedback to the patient and translating a summary of their test performance and any recommendations.
Although there are many alternative versions of the ACE-III, it is important to remember that interpreters will not have had a professional training in administering cognitive screening tools and research has shown interpreters may inadvertently edit responses, leading to higher scores
what can the ace tell you
indication of whether or not a patient is performing as expected, compared to people of the same age
If they perform below the cut off on the ACE-III, this indicates the possibility of a degree of cognitive impairment
The ACE-III cannot identify the cause of a patient’s cognitive impairment
