Dementia diagnosis

To diagnose your condition, your doctor will review your medical history and symptoms and conduct a physical examination. Doctors may order a number of tests to diagnose dementia and rule out other conditions.
 
Cognitive and neuropsychological tests Doctors will evaluate your thinking (cognitive) function. A number of tests measure thinking skills such as memory, orientation, reasoning and judgment, language skills, and attention. This test is used to determine whether you have dementia, how severe it is and what part of your brain is affected
.
Neurological evaluation Doctors will evaluate your movement, senses, balance, reflexes and other areas. This can also be used to diagnose other conditions.
 
Brain scans Doctors may order brain scans, such as a CT or MRI, to check for evidence of stroke or bleeding and to rule out the possibility of a tumor.
 
Laboratory tests Simple blood tests can rule out physical problems that can affect brain function, such as vitamin B-12 deficiency or an underactive thyroid gland.
 
Psychiatric evaluation This is also very important and mental health specialist (psychologist or psychiatrist) may evaluate whether depression or another psychological condition may be causing your symptoms.
