One in four severe brain injury patients had cognitive-motor dissociation detected on EEG or fMRI. Despite appearing unresponsive, these patients repeatedly showed covert consciousness. Younger age, ...

At least 25% of unresponsive patients with a disorder of consciousness show signs of brain activity, an estimate that is higher than previous studies suggest. "We found that at least 1 in 4 patients ...

A severe brain injury can leave patients unresponsive to stimuli, but they may be more aware than we realize. A new study of brain activity has shown that up to a quarter of unresponsive patients may ...

Some comatose patients with severe brain injury might be paying closer attention to their surroundings than previously thought, a new study says. Photo by Adobe Stock/HealthDay News Some comatose ...

Coma scales have been developed for evaluating depth of consciousness and helping in prediction of outcome. This last issue is best assessed by several other clinical and neurophysiologic tests. For ...

Researchers from the University of Montreal observed previously unreported spikes of neuronal activity, which they called Nu-complexes, in the EEG of one human patient in a deep coma. In order to see ...

Sleep spindles helped predict recovery in unresponsive patients with acute brain injury. About a third of unresponsive patients showed well-formed sleep spindle patterns. Spindles frequently preceded ...

Scientists have discovered a hidden sign of consciousness in comatose patients that shows they can hear and understand the world around them. The study found bursts of organized, fast frequencies ...

Some comatose patients with severe brain injury might be paying closer attention to their surroundings than previously thought, a new study says. About 1 in 4 patients respond to instructions covertly ...
