Are sleepness nights to blame for Alzheimer’s disease? Lack of shut-eye may cause long-term memory loss

Biblia spune: ,,Cei ce dorm, dorm noaptea“. Cu alte cuvinte, noaptea este pentru somn. Lampa cu gaz și curentul electric ne-au dereglat definitiv ciclul circadian. Nu ne mai rămâne decât să culegem roadele nesănătoase ale vieții noastre de somnambuli.

Pe de altă parte, când vă va mai găsi cineva dormind, spuneți-i în glumă: ,,Mă tratez!“ Aveți suportul oamenilor de știință, care văd în somnoterapie una din cele mai eficace metode de prevenire și chiar de încetinire a bolilor bătrâneții. Aceasta este esența articolului de mai jos.

Poor sleep allows a memory-robbing protein to build up in the brain
In turn, higher levels of this beta-amyloid protein then disrupt sleep
This leads to a vicious circle that could result in Alzheimer’s disease

Sleepless nights don’t just affect your memory the next day. They could raise your odds of developing Alzheimer’s. Researchers believe that poor sleep allows a memory-robbing protein to build up in the brain.

In turn, higher levels of this beta-amyloid protein then disrupt sleep – leading to a vicious circle that could result in Alzheimer’s disease.

If sleep is as important as believed, sleep therapies could help delay the onset of the disease, as well as slow its progression in those who already have it.

The Californian researchers said: ‘This discovery offers hope. Sleep could be a novel therapeutic target for fighting back against memory impairment in older adults and even in those with dementia.’

Alzheimer’s and other forms of dementia affect more than 800,000 Britons and, worldwide, the number of sufferers is predicted to treble to 44 million by 2050 as the population ages.

With existing drugs of limited use and search for a cure ending in disappointment time and time again, some doctors argue that changes to diet and lifestyle offer the best chance of staving off the disease.

The latest Californian study looked at the relationship between beta amyloid, quality of sleep and the ability to memorise facts.
