Screening Tests for Alzheimer’s or dementia Diagnosis

There are no definitive tests for Alzheimer’s that can be taken at home. These screening tests present indications of Alzheimer’s or Dementia but are no substitute for visiting your physician at the first sign of progressive memory loss.
These tests will not differentiate between vascular dementia or Alzheimer's Disease, but they will confirm your suspicions.


TESTS TO DO AT HOME FOR PRESCREENING Dementia
 Diagnosing Alzheimer’s early is vital for receiving medications to delay symptoms and prolong life. An early diagnosis also gives the patient the opportunity to contribute to many of the decisions that will need to be made later. A test that is often given first, is the Clock Drawing Test.

  THE CLOCK DRAWING TEST The person undergoing testing is asked to;
Draw a clock
Put in all the numbers
Set the hands at ten past eleven. Scoring system for Clock Drawing test (CDT)
There are a number of scoring systems for this test. The Alzheimer’s disease cooperative scoring system is based on a score of five points.
1 point for the clock circle
1 point for all the numbers being in the correct order
1 point for the numbers being in the proper special order
1 point for the two hands of the clock
1 point for the correct time. A normal score is four or five points. Test results
The test can provide huge amounts of information about general cognitive and adaptive functioning such as memory, how people are able to process information and vision. A normal clock drawing almost always predicts that a person’s cognitive abilities are within normal limits. The clock Drawing test does offer specific clues about the area of change or damage. ____________________________________________________________
  A SIMPLE WORD TEST
This is a simple word test that may help in the early diagnosis of Alzheimer’s. It deals with the way in which our brain saves and stores memories. Since some words are learned earlier in childhood and used more frequently in adulthood, certain words will be more difficult for the Alzheimer’s patient to recall.  Word association tests such as this seem to work well in detecting early stage Alzheimer’s.
  • First ask the individual to name all the animals they can think of in one minute.
  • Then ask her/him to name all the types of fruit they can remember in one minute.
Researchers have found that people with early Alzheimer’s are able to list only 10 to 15 words in contrast to the 20 to 25 words from a healthy individual. ____________________________________________________________
