Scientists have found that in dementia, blood flow in the brain can be impaired due to the loss of a key lipid, which causes overactivity of blood vessels and subsequent starvation of brain tissue.Restoring the missing molecule in experiments restored normal blood flow in the brain.The study identified that the problem is not just in the neurons, but also in the blood vessels and their regulation by astrocytes and lipid signals.[7] The main finding is that supplementation with this molecule can reverse the circulatory disturbances associated with dementia.The authors suggest that these results open up the possibility of new therapeutic approaches aimed at improving vascular function in dementia.The article does not provide specific statistics or percentage data on efficacy in humans.[7
