When assessing the Dementia Stages there are three main scales or systems that are used by most Doctors. The Clinical Dementia Rating Scale (CDR) and the Functional Assessment Staging (FAST) Scale are used mainly for the initial assessment of the Dementia Stages. The Global Deterioration Scale (GDS) is used to fine tune the assessment once dementia has been diagnosed.
Below is a quick rundown of each of the three scales used for assessing what stage of dementia a patient is in.
Clinical Dementia Rating (CDR) Scale.
This is the most widely used staging system in dementia research. Here, the person with suspected dementia is evaluated by a health professional in six areas: memory, orientation, judgment and problem solving, community affairs, home and hobbies, and personal care and one of five possible stages is assigned.
1. CDR-0 -- No dementia
2. CDR-0.5 – Mild-Memory problems are slight but consistent; some difficulties with time and problem solving; daily life slightly impaired
3. CDR-1 Mild-Memory loss moderate, especially for recent events, and interferes with daily activities. Moderate difficulty with solving problems; cannot function independently at community affairs; difficulty with daily activities and hobbies, especially complex ones.
