It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration or damage that has occurred, environmental factors, disruption to a person's ...
Magnetic resonance imaging (MRI) scans to assess brain structure, connectivity, and the extent of white matter disease; Positron emission tomography (PET) scans to assess how well the brain uses glucose, and the extent of amyloid plaques and tau tangles. Neuropathological examination if a participant dies and has consented to autopsy.
Structural MRI scans often reveal frontal lobe and/or anterior temporal lobe atrophy, but in early cases the scan may seem normal. Atrophy can be either bilateral or asymmetric. [ 13 ] Registration of images at different points of time (e.g., one year apart) can show evidence of atrophy that otherwise at individual time points may be reported ...
CT scans can expose patients to levels of radiation 100-500 times higher than traditional x-rays, with higher radiation doses producing better resolution imaging. [37] While easy to use, increases in CT scan use, especially in asymptomatic patients, is a topic of concern since patients are exposed to significantly high levels of radiation. [36]
A new study found the biggest risk factors and predictors at 60 for dementia at 80. ... But medical specialists who work with dementia patients say the findings are similar to what they see in ...
Composite images from an fMRI scan. Physicians use fMRI to assess how risky brain surgery or similar invasive treatment is for a patient and to learn how a normal, diseased or injured brain is functioning. They map the brain with fMRI to identify regions linked to critical functions such as speaking, moving, sensing, or planning.

The authors cited “the global brain health crisis” as one of the motivators for their work; in the United States alone, 1 in 7 people have dementia, and every four minutes someone dies from a ...
