How many levels are there on the global deterioration scale?

The Global Deterioration Scale (GDS), developed by Dr. Barry Reisberg, provides caregivers an overview of the stages of cognitive function for those suffering from a primary degenerative dementia such as Alzheimer’s disease. It is broken down into 7 different stages.

What is the GDS speech therapy?

The GDS is a standardized measure that provides an overview of cognitive function for persons diagnosed with dementia. Using this tool as the first step of the occupational therapy process is critical in identifying which stage of dementia your patient is in.

What is primary degenerative dementia?

Abstract. Primary degenerative dementia (PDD) and multiinfarct dementia (MID) are the two most common categories of cognitive decline in old age. The definitions of these two clinical entities are currently based on clinical evaluation and on the exclusion of other underlying causes, and still lack a consensus.

What is the number scale for dementia?

A score of 20 to 24 suggests mild dementia, 13 to 20 suggests moderate dementia, and less than 12 indicates severe dementia. On average, the MMSE score of a person with Alzheimer’s declines about two to four points each year.

How is severity of dementia assessed?

MMSE: This test is graded by severity and has been used extensively in memory clinics to measure response to medication and guide decisions: 20-26 = mild cognitive impairment; 10-20 = moderate impairment; and less than 10 indicates severe impairment.

What is a global CDR score?

CLINICAL DEMENTIA RATING SCALE (CDR) The CDR is a global rating scale for staging patients diagnosed with dementia (Table 16.6). The CDR evaluates cognitive, behavioral, and functional aspects of Alzheimer disease and other dementias.

What is Functional Assessment Scale?

Functional Assessment Scale — Instructions (Assessment of Functional Abilities and Supports) Measurements of functional abilities and supports are commonly used across the country as a basis for differentiating among levels of care giving.

What is functional assessment tool for dementia?

FAST stands for Functional Assessment Staging Tool. This scale was developed by Dr. Barry Reisberg, who is a leading expert in Alzheimer’s disease. It’s used to help doctors, medical professionals and family members understand, talk about and follow the progression of dementias such as Alzheimer’s disease.

Which assessment is used for dementia?

People with symptoms of dementia are given tests to check their mental abilities, such as memory or thinking. These tests are known as cognitive assessments, and may be done initially by a GP. There are several different tests. A common one used by GPs is the General Practitioner Assessment of Cognition (GPCOG).

How is CDR global score calculated?

Clinical Dementia Rating (CDR) Ratings are assigned on a 0–5 point scale, (0 = absent; 0.5 = questionable; 1= present, but mild; 2 = moderate; 3 = severe; 4 = profound; 5 = terminal). A global summary score is obtained, leading to the use of the CDR for grouping patients on severity of dementia.

How do you calculate CDR?

The constant default rate (CDR) is calculated as follows:

1. Take the number of new defaults during a period and divide by the non-defaulted pool balance at the start of that period.
2. Take 1 less the result from no.
3. Raise that the result from no.
4. And finally 1 less the result from no.

What is CDR Sum box?

The Sum of Boxes (later shortened to SumBoxes, or CDR-SBTM) provides a more quantitative measure of dementia severity than the global CDR. The CDR-SB frequently is used to assess Alzheimer disease progression in clinical research7-9 and as a primary outcome measure in Alzheimer disease clinical trials.

What is the dementia Severity Rating Scale?

The Dementia Severity Rating Scale (DSRS) is a brief informant-rated, multiple-choice questionnaire made up of 12-items that measure functional abilities and parallel CDR content 7. The DSRS requires minimal staff training to administer, takes five minutes to complete, and can be completed via mail, Internet, or phone.
