When comparing a depressed brain versus a normal brain, scientists have found some subtle but important differences including grey matter abnormalities, brain shrinkage, and a more active amygdala in depressed brains. This image shows a PET scan of a patient with Alzheimer's disease on the left and an elderly person with normal memory on the right. CT study of brain and whose findings were normal. Dementia is not a specific disease; it is a broad term that characterizes many different conditions, such as Alzheimer's disease, vascular dementia, frontotemporal dementia, and other disorders. Functional Signs Of Dementia Functional imaging of the brain can include a functional MRI, a positron emission tomography (PET), or a single photon emission computed tomography (SPECT) scan . They are in the regions of the amygdala, the prefrontal cortex, and the extended paralimbic structures. Shown are PET scans that track tau (top row) and beta-amyloid from two normal older people and one patient with Alzheimer’s disease (AD). Brain Scan : Normal Vs Alzheimer's Sufferer . However, it’s difficult to distinguish normal brain cell decline with Alzheimer’s using scans, so it’s not normally used in the diagnosis. MRI scans of the volunteers are taken every six to twelve months for a period of approximately 3 years. MRI scans and other tools to detect and diagnose dementia are helpful but not definitive. Forgetting the names make them reveal an incorrect name of the object.
