Doctors usually do various tests based on patient’s memory and thinking and also check family backgrounds. If AD is suspected, the patient is made to undergo brain imaging, most likely a magnetic resonance imaging (MRI). This shows the degree of atrophy of the brain and is an accurate detector of AD (Giovanni et al, 2010). A possible condition for nervousness is Depression, also referred to as clinical depression.
