Alzheimer's Disease Assessment Scale (Cognitive Subscale)

The Alzheimer’s Disease Assessment Scale (Cognitive Subscale) measures the severity of cognitive dysfunctions characteristic of persons with Alzheimer’s disease. The word recall task is administered first. The next 10 minutes are spent in open-ended conversation to assess speech function. Then the other cognitive tasks are administered. Patients are rated on a scale from 0-5 on most questions, reflecting the degree of severity of dysfunction. Questions 1, 6, and 7, are rated on a scale of 0-10, 0-8, and 0-12, respectively. A rating of 0 signifies no impairment on a task or absence of a particular behavior, while a rating of 5 (or 8, 10, or 12) is reserved for the most severe or most frequent degree of impairment. A rating of 1 refers to a very mild indication of impairment on a given task. Ratings of 2, 3, or 4 refer to mild, moderate, and moderately severe impairments on the given task, respectively. The ADAS-COG requires about 30-45 minutes to administer completely.

Task Description Rating
Word Recall * Asess the patient's ability to recall a list of frequent, easy-to-imagine words (e.g., present a list of 10 words, followed by a delay, and record the number of incorrectly recalled or missed words as a rating out of 10)
Naming * Assess the patient's ability to correctly name presented objects and fingers on a hand (e.g., present a collection of 5 items and record the number of objects the patient is unable to name or identify correctly)
Commands * Assess the patient's understanding of and ability to fulfil 1-5 step commands (e.g. present a list of 5 commands of increasing complexity and record the number of commands the patient failed to follow)
Constructional praxis * Drawing four geometric forms using a given pattern (e.g. present a collection of patterns and record the number of patterns the patient can correctly express by drawing)
Ideational Praxis * Assess the patient's ability to perform a familiar but complex sequence of actions (e.g., ask the patient to comb his or her hair, turn on the television, make a sandwich, tie a pair of shoes, and assess his or her ability to carry it out)
Orientation * Assess the patient's ability to orient him or herself in time and space (e.g., ask the patient to locate his or her residence on a map, to tell the time of day, or to judge how many seconds or minutes have passed after a given period of time)
Word Recognition * Assess the patient's ability to discriminate new words from previously-presented ones (e.g., present the patient with a list of 12 words and record the number of times the patient fails to recognize the word presented)
Instructions Remembering Assess the patient's ability to remember instructions from the previous recognition task
Spoken Language Ability Assess the patient's quality of speech
Word-finding Difficulty Assess the patient's ability to communicate verbally
Comprehension Assess the patient's ability to understand speech spoken to him or her
