How is Alzheimer’s disease diagnosed?
There's no specific test today that confirms you have Alzheimer's disease. It is mainly based on the information that the patient or family member provides and results of various tests that can help clarify the diagnosis. 

To help distinguish Alzheimer's disease from other causes of memory loss, the following types of tests can be helpful:

  • Medical history
  • Neurological exam – Reflexes, coordination, muscle tone and strength, eye movement, speech, sensation
  • Lab tests: Such as thyroid disorders or vitamin deficiencies
  • Mental status testing 
  • Neuropsychological testing
  • Brain imaging: Magnetic resonance imaging (MRI), Computed tomography (CT), Positron emission tomography (PET) 
  • Future diagnostic tests: Additional approaches to brain imaging, more-sensitive tests of mental abilities, and measurement of key proteins or protein patterns in blood or spinal fluid (biomarkers) are recent advances in diagnosis, which are being further developed in the research lab.

  • Alzheimer's patients can still feel emotion long after memories have vanished
    A new University of Iowa study further supports an inescapable message: caregivers have a profound influence -- good or bad -- on the emotional state of individuals with Alzheimer's disease. Patients may not remember a recent visit by a loved one or having been neglected by staff at a nursing home, but those actions can have a lasting impact on how they feel. The findings of this study are published in the September 2014 issue of the journal Cognitive and Behavioral Neurology. "Our findings…

  • Vitamin D deficiency increases risk of Dementia
    In a population-based study of its kind, a team of researchers has found a link between vitamin D consumption and the risk of developing dementia. Older people who do not get enough vitamin D could double their risk of developing the condition. http://www.medicalnewstoday.com/articles/280704.php
  • Powerful Self-Portraits Reveal Artist's Descent Into Alzheimer's Disease
    Utermohlen's self-portraits provide a stark look at the devastating effects of Alzheimer's. As the artist struggled to keep in touch with the world around him, his works became flatter, more abstract, with a new loss of details and spatial sense. By 2000, Utermohlen's memory and technical skills had deteriorated to the point where his heartbreaking portrayal of himself was simply a scribbled skull and the barest shadows of facial features. http://www.mymodernmet.com/profiles/blogs/william-…
