Resumen de Brain drain.

Maiken Nedergaard, Steven A. Goldman

• The authors discuss how the brain eliminates proteins and other wastes and their role in causing the cognitive problems encountered in neurodegenerative disease. They say that brain cells process their own wastes during sleep through perivascular spaces. They note that lack of sleep can contribute to the development of neurodegenerative diseases such as dementia, Alzheimer's disease, and mental illness.
