Brain complexity declines in Alzheimer's disease

Alzheimer's disease can be evaluated with brain stimulation, finds study

As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained. Most conscious processes also become more impaired as AD progresses, including attention, working memory, episodic memory and executive function, while unconscious processes, such as procedural or muscle memory, operant condition…

Brain Stimulation Method Can Evaluate Consciousness in Alzheimer’s Disease

Researchers have determined that a measure of brain complexity, derived from magnetic stimulation and EEG, can effectively evaluate the integrity of conscious processing in patients with Alzheimer's disease. The findings offer a new potential metric for tracking disease progression.

Brain Stimulation Can Help Measure Alzheimer's Disease Progression

Boston University researchers say that a measure derived from electroencephalography (EEG) combined with transcranial magnetic stimulation (TMS) can distinguish people with Alzheimer’s disease (AD) from healthy older adults by detecting reduced brain response complexity. The study, published in the journal Neuroscience of Consciousness, that a measure that has been used to assess coma and minimally conscious states, called perturbation complexit…
