Imaging Studies May Motivate Behaviors to Reduce Cognitive Decline

An emerging hot topic in the field of neurology is the use of brain imaging to help experts treat and care for cognitive decline in patients.

A new review suggests imaging studies can be used as a tool to help neurologists, psychiatrists, and other clinicians to measure and manage cognitive declines in patients.

Experts believe the imaging findings can motivate patients to make beneficial lifestyle changes to reduce risk for Alzheimer’s disease.

The concept that cognitive decline can be identified early and prevented by applying quantitative brain imaging techniques is the focus of “Hot Topics in Research: Preventive Neuroradiology in Brain Aging and Cognitive Decline,” a review published online in American Journal of Neuroradiology (AJNR).

In the review, an international team suggest a framework in which neuroradiologists work as part of a team of clinical neuroscientists (neurologists, psychiatrists, neuropsychologists, etc.) can be an effective strategy to prevention of cognitive decline in populations at high risk for dementia.

Researchers believe the application of quantitative neuroradiology will particularly aid individuals with lifestyle, genetic, and other associated risk factors.

“I believe neuroradiology, and especially quantitative MRI technology, will have a huge impact in the future of diagnosis and treatment of Alzheimer’s disease, since there is compelling evidence for the baseline size of hippocampus as a key determinant of risk for future cognitive decline, and since many lifestyle factors can cause atrophy or expansion in the volume of this critical brain structure,” says neurologist Majid Fotuhi, M.D., Ph.D., of Johns Hopkins University.

Such work is already happening at University of California, Los Angeles and other institutions that meld these approaches into novel ways to improve patient care.

“We are working closely with neuroradiologists to redefine how we can reduce risk for Alzheimer’s with quantitative neuroimaging that helps us pinpoint symptom-relevant volume loss in the brain and subsequent targets for tracking our lifestyle-based interventions,” says Dr. David Merrill, a geriatric psychiatrist at University of California, Los Angeles Medical Center.

“Recent advances have improved the ability to characterize imaging markers along the trajectory of Alzheimers disease, starting in the pre-clinical phase. These markers, including structural, functional, and molecular imaging are being used in the AD diagnostic criteria” says Howard Aizenstein, M.D., Ph.D., a psychiatrist at University of Pittsburgh.

Fotuhi sees imaging findings as a unique motivator for patients to make positive lifestyle changes.

“Patients seem to enjoy reviewing results of their imaging studies, more so than reading the results of their blood tests or other clinical evaluations. For example, they can see with their own eyes whether there are any strokes or atrophy in their brain. This can have a powerful impact on them and on their determination to make changes in their lifestyle in order to improve their brain health,” he adds.

Experts explain that that as many as three million cases of Alzheimer’s dementia worldwide can be prevented with as little as a 10 percent reduction in the burden of preventable lifestyle.

Lifestyle risk factors that can be altered to potentially prevent cognitive declines are obesity, diet, sleep, hypertension, diabetes, depression, supplementation, smoking, and physical activity.
