Dementia - Diagnosis

  • ​Interview
    You and your caregiver will be interviewed by a neurologist and a specialist nurse to understand the problems faced.
  • Assessments
    A cognitive and language ability test will be conducted to help the neurologist make a diagnosis.

Other tests include:

  • Blood
    Samples will be tested for vitamin deciencies, thyroid disorders, and markers of infection/inflammation. Fasting is not required.
  • Brain Imaging
    A Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scan looks for a treatable cause of dementia or the presence of atrophy (shrinkage) in the brain (Figure 1). A Positron Emission Tomography (PET) scan can also confirm the presence of amyloid and tau pathology.
