The Patient Satisfaction Rating is an average of all responses to the care provider related question shown above from our internal platform, PMX Feedback. Responses are measured on a scale of 1 to 5 with 5 being the best score. Scores reflect either the most recent 12 months of surveys or the most recent 30 surveys overall. Data is updated monthly and comments remain on the profile for 12 months.
Comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of Penn Medicine.
Patients that are treated in outpatient or hospital environments may receive different surveys.
Dr. Veasey’s laboratory focuses on identifying the molecular mechanisms underlying neural injury in sleep disorders and sleep disruption. The present focus of her lab is understanding the molecular mechanisms by which sleep disruption injures and even kills select neurons. Previously sleep researchers believed that all neurobehavioral consequences of sleep loss were fully reversible. Dr. Veasey's lab has led the way in discovering that chronic short sleep and sleep fragmentation induce loss of wake-activated neurons, neurons essential for alertness and optimal cognitive performance. Most recently her lab has discovered that chronic sleep loss incites an amyloid cascade within locus coeruleus neurons and that this cascade leads to an unstoppable progression of tau degeneration marching throughout the forebrain. Wake-active neurons in the brain are essential for optimal wakefulness and cognitive performance. Although there are many groups of these neurons, each playing unique roles in wake responses, the catecholaminergic wake neurons in the locus coeruleus and dorsal midbrain are particularly sensitive to diverse injuries, including aging and neurodegenerative processes. We recently identified SIRT1 as a key regulator of wake-active neuron function and integrity, a metabolic homeostat that is lost with aging. A key focus for the lab now is to identify why this is lost and why wake neurons rely so heavily on this protectant. Her lab is now keenly intrigued by sleep loss neuroinflammatory injury to locus coeruleus neurons that results in synaptic pruning and cognitive impairments.
