  • Pair of Penn Medicine Studies Featured in Archives of Neurology

  •  

Two Penn Medicine studies were released this week by the Archives of Neurology, one of the JAMA/Archives journals.

The first article, led by Daniel Weintraub, MD, associate professor of Psychiatry and Neurology in the Perelman School of Medicine at the University of Pennsylvania, notes that half of patients with Parkinson's disease (PD) and psychosis receive prescriptions for antipsychotic agents, including drugs that have the potential to worsen Parkinson's symptoms. The frequency of use of these agents has not changed since the FDA issued a black box warning about using these drugs in patients with dementia, according to a report in the July issue of Archives of Neurology, one of the JAMA/Archives journals.

To read more about Dr. Weintraub's study, see the JAMA/Archives news release. This research was supported by grants from the National Institute of Mental Health.

In the second study, David Wolk, MD, assistant professor of Neurology in the Perelman School of Medicine at the University of Pennsylvania and colleagues studied the use of positron emission tomography (PET) imaging to help identify findings in brain tissue associated with Alzheimer's disease (AD).

The research team evaluated use of a tracer called fluorine 18-labeled flutemetamol and conducted PET scans on seven patients who were given a dose of this substance. Researchers found correspondence between readings of the PET scans and evidence of amyloid lesions—the plaque associated with AD—provided by microscopic evaluation of the biopsied tissue.

"With the potential emergence of disease-specific interventions for AD," said Dr. Wolk , "biomarkers that provide molecular specificity will likely become of greater importance in the differential diagnosis of cognitive impairment in older adults."

For more information about this study, see the JAMA/Archives news release. Dr. Wolk's study was entirely sponsored by GE Healthcare.
