Testing Methods for Alzheimer’s
Testing is a very important part of being able to determine if someone has Alzheimer’s disease or not. Making sure that you are testing early will help in making sure that the individual is getting the help that they will need to have right away. There are three main tests which have been shown to be effective in testing for Alzheimer’s disease.
Scents are very strong mental facilities. They have links to memories as well as to other parts of the brain like emotion. By being introduced with certain smells, it should be very easy to determine what you smell.
While there are many different scents which can be used in a test like this, scientists have developed ten scents which have been proven to be highly effective in determining whether an individual might have Alzheimer’s disease. These include: strawberry, soap, smoke, pineapple, natural gas, menthol, lilac, lemon, leather, and clove.
To test the individual, they will be exposed to the scent and asked to identify it. This will give the doctor a perception of whether the individual has a problem in the brain which will need to be looked at further with brain imaging scans.
Another way to test the individual is to present them with 3 quarters, 7 dimes and 7 nickels and ask them to make up change for one dollar. This challenges the parts of the mind dealing with association. Since there are different denominations and different patterns which can be used to create one dollar, those who have problems with cognition will take upwards of 2 minutes while a healthy individual will only need around 15 seconds.
Clock Drawing Test
Many of the doctors will use a test in which they ask an individual to draw a clock. The problem with this is that it is a normal everyday object which should be easy to remember without looking at it. Those with Alzheimer’s disease might have trouble drawing a closed loop for the clock face, putting the right numbers in the right order on the face or making sure that when given a time that they can face the hands to the right numbers.
These tests and others will help to determine whether a patient has Alzheimer’s disease as well as what the severity is. It is likely that they will be followed by something like a CAT scan in order to determine what is needed.
