This review summarizes key findings of the best established imaging markers of Alzheimer's disease, including markers of amyloid, metabolic and synaptic function, structural connectivity and brain atrophy.
Altered tryptophan metabolism in non-tumoral brain, measured by PET, may be a novel imaging marker of brain tumor-associated depression.
Finally, behavioural and brain imaging markers were significantly correlated with the duration of cocaine abuse, suggesting (but not proving) that changes in brain systems controlling attention and compulsive behaviour may be a consequence of prolonged cocaine consumption.
There is a complete overlap between carotid and brain MRI participants, allowing for the investigation of carotid plaque constituents in relation to brain imaging markers.
Alkon's test is just one in a number of new approaches to early detection, including measuring molecules linked to the disease in blood and cerebrospinal fluid, as well as new brain-imaging markers that can detect signs of Alzheimer's, such as buildup of the protein beta-amyloid a hallmark of the disease.
Furthermore, imaging markers could help to understand the link between brain structures changes and the presence of BPSD.
Brain imaging studies of healthy humans (people without brain damage) suggest something similar.
With the appropriate radiolabeled tracers, positron emission tomography (PET) enables in vivo human brain imaging of markers for neurotransmission, including neurotransmitter synthesis, receptors, and transporters.
These changes may indicate an imbalance between the serotonin and kynurenine pathways and serve as a molecular imaging marker of brain tumor-associated depression.
Brain imaging studies reveal neural correlates of rhythm perception in the brain.
