The 64th Annual Meeting of the American Academy of Neurology

The annual meeting of the American Academy of Neurology was held from April 21 to 28 in New Orleans and attracted approximately 12,000 participants from around the world, including clinicians, academicians, allied health professionals, and others interested in neurology. The conference highlighted recent advances in neurological disorders, with presentations focusing on the diagnosis, management, and treatment of disorders impacting the brain and nervous system.

In one study, Amer Alshekhlee, M.D., of Saint Louis University, and colleagues evaluated whether tissue plasminogen activator (tPA) or thrombolysis was safe to administer to children with strokes.

"We evaluated approximately 9,300 children over the last 12 years using a large database of children. We found that the rate of tPA use was very low. We only identified 75 children who received tPA or thrombolysis," Alshekhlee said. "The main reason the number was so low was because of a scientific statement from the American Heart Association-Stroke in Children council, which recommended the use of tPA in children if they were involved in a clinical study, but not for use in clinical practice. However, this statement was not necessarily directed toward older adolescents, which is who we evaluated in this study."

The investigators also found that the risk of cerebral hemorrhage was approximately 4 percent in children, which was similar, if not lower, than that found in adults.

"In addition, the mortality rate was approximately 12 percent, which was roughly the same as that found in adults," Alshekhlee said. "Lastly, factors associated with hemorrhage and death were also similar to those found in the adult population."

In another study, Daniel Corcos, Ph.D., of the University of Illinois in Chicago, and colleagues found that weight training increased strength in patients with Parkinson's disease and improved the symptoms of the disease.

"We found that, when patients with Parkinson's disease did progressive resistance exercises (weight training) over a two-year time period, the measure of Parkinson's disease (the Unified Parkinson's Disease Rating Scale-Motor Exam) was improved by seven points as compared to a program involving flexibility training, balancing, and/or non-progressive strengthening," Corcos said. "The practicing neurologist should consider recommending an exercise program that involves weight training to patients with Parkinson's disease, as it improves neuromuscular function. Patients with Parkinson's disease become weak due to a lack of activity and dopamine deficiency, which leads to reduced muscle function."

J. Robin Moon, D.P.H., of the Harvard School of Public Health in Boston, and colleagues found that foreign-born Hispanics had a lower stroke risk than non-Hispanic whites with similar socioeconomic backgrounds.

"The study found that after accounting for socioeconomic factors like education, income, and wealth, foreign-born Hispanics were 42 percent less likely than non-Hispanic whites to have a first stroke," Moon said. "Hispanics born in the United States had higher risk of stroke than non-Hispanic whites, but this difference was completely wiped out once we adjusted for socioeconomic factors. In other words, foreign-born Hispanics have lower stroke risk than non-Hispanic whites with similar socioeconomic backgrounds, but this protective effect does not extend to Hispanics born in the United States, who have stroke risk similar to non-Hispanic whites with similar education and financial resources."
