It’s long been believed that a lack of sleep could be bad for the brain. But a new study offers a more colorful, yet dire description of this consequence — it could turn the brain into a “cannibal” of sorts, with synapses being “eaten” by other brain cells, and even increase the chances of chronic sleep loss sufferers acquiring Alzheimer’s disease later in life.
Not getting enough shut-eye at night might not sound as bad as it seems at first, according to a report from New Scientist. Healthy brain connections initially may be protected once brain cells consume their worn-out equivalents. But study lead author Michele Bellesi of the Marche Polytechnic University (Italy) believes that a chronic lack of sleep may have some dangerous long-term effects on the human brain, including a higher risk of neurological disorders such as Alzheimer’s disease.
