Alzheimer's disease can begin with oxygen deficit in the brain, according to world leading researchers in Gothenburg.
Oxygen deficit in the bran is caused by a dramatic onset of cardiac arrest. A study of 25 patients in Uppsala shows that the brain responds by forming the substance that breaks down nerve cells in the brains of patients with Alzheimer's disease.
- The first 24 hours are calm, but then it suddenly intensifies and a cascade of nerve-damaging beta amyloid is formed, says Kaj Blennow, professor in Neurochemistry at the Sahlgrenska Academy and one of the world's leading Alzheimer's researchers (cited in GP).
Several new research projects have been launched thanks to the finding. More cardiac arrest patients will be examined, as well as patients with sleep apnea.
- We're only at the start of something new. But much speaks for that the oxygen deficit triggers the pathological changes in the process that eventually leads to Alzheimer's disease, says Kaj Blennow.
