Mice study finds altered brain connectivity after prolonged anesthesia
Prolonged anesthesia, also known as medically induced coma, is a life-saving procedure carried out across the globe on millions of patients in intensive medical care units every year.
But following prolonged anesthesia which takes the brain to a state of deep unconsciousness beyond short-term anesthesia for surgical procedures it is common for family members to report that after hospital discharge their loved ones were not quite the same. It is long known that ICU survivors suffer lasting cognitive impairment, such as confusion and memory loss, that can languish for months and, in some cases, years, said Michael Wenzel, MD, lead author of a study published in

What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology. – What is neurology? – Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them. – Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.
The findings support reports of neuro-cognitive changes after medically induced comas, a procedure that has been relied upon in treating many COVID-19 patients during the pandemic.
