Brain Health Program Can Help Prevent Dementia By anSLey FranCo
An estimated one in five Americans 65 years or older has mild cognitive impairment, and one in seven has dementia. By 2050, the number of Americans with dementia is expected to triple. In response to this coming challenge, the University of Alabama at Birmingham has started a pilot program at two primary care clinics that focuses on helping patients prevent cognitive decline. The Brain Health Advocacy Mission (BHAM) will encourage patients make smart choices to improve their brain health. “It is now well-understood that risk factors of cognitive decline and dementia are largely treatable,” said Ronald Lazar, PhD, a UAB professor of neurology and director of the Evelyn F. McKnight Brain Institute. “It's not that these risk factors
for the BHAM clinics. The clinics provide patients a roadmap to maintaining brain health that is built around the AHA’s Life’s Simple 7, a set of lifestyle targets that include managing blood pressure; maintaining healthy cholesterol levels; reducing blood sugar; physical activity; healthy diet; healthy weight; and not smoking, along with five other factors that impact brain health - depression, social isolation, excessive alcohol use, sleep disorders and hearing loss. “A large number of Americans are affected by these lifestyle issues. About one-third of our population has hypertension, and approximately 10 percent has diabe-

cause dementia. They just make the brain more vulnerable to these things that cause dementia. And when we attack these early, it makes dementia much less likely to occur later on.” Lazar was the lead author of A Primary Care Agenda for Brain Health, a scientific statement issued by the American Heart Association that provides the framework

UAB Neurosurgeons Expand Their Toolbox By Laura Freeman
Radiofrequency ablation made big news in the 1990s when it became the standard of care for correcting some types of heart arythmmias. In the years that followed, it became a tool for treating disorders in many areas of the body. Now two neurosurgeons from UAB Heersink School of Medicine are using the technology to treat drug resistant focal epilepsy for the first time in Alabama. Nicole Bentley, MD and Kirsten Riley, MD of the department of neurology teamed up for the first case. It involved Ashley Williard a recent college graduate. Despite having seizures since

early childhood, Williard was active in ballet, swimming, tennis and cheer. However, her seizures had increased in frequency to about twice a week in college, which was making her life more difficult.
“Focal epilepsy is triggered by lesions in specific areas of the brain,” Bentley said. “The first step to eliminate the lesions is to locate them. This requires implanting electrodes and waiting to

capture a seizure in real time as it is happening so we can precisely map out the location of lesions triggering the attack and the areas they affect.” Riley said: “The mapping procedure is known as stereo-electroencephalography. Electrodes are placed directly in the brain in areas that the epileptologist and neurosurgeon have identified as the most likely seizure onset zone. The temporal lobe is where most problems begin.” By taking advantage of the electrodes that are already in place, the RF procedure offers minimally invasive access to areas near the focal lesions without the need for a craniotomy.
