  • Meet Dr. Khera!

    Dr. Khera received her MD degree from Wayne State University in Detroit, MI and completed her neurology residency at the University of Texas Southwestern Medical Center in Dallas (UTSW).  She then obtained further training in Behavioral Neurology & Neuropsychiatry.  She is now assistant professor at UTSW.  She sees patients at the UTSW memory clinic and is also interested in clinical research, especially in the topic of caregiver burden.
