New hope for Alzheimer's patients: open the blood-brain barrier in a non-invasive, reversible manner
Alzheimer's disease (AD) is a progressive degenerative neurological degenerative disease (other name: Alzheimer's disease). Clinically, it is characterized by memory impairment, aphasia, indiscriminateness, loss of recognition, visual spatial impairment, executive dysfunction, and changes in personality and behavior, and the etiology has not been known so far. There is no cure.
Recently, Canadian scientists have opened the blood-brain barrier of five Alzheimer's patients in a non-invasive, reversible, and safe process, with no significant adverse effects. Focused ultrasound combined with microbubble technology can effectively open the blood-brain barrier, and can also act on brain tumor patients through implant devices.
The blood-brain barrier refers to the barrier between the plasma and brain cells formed by the brain capillary wall and glial cells and the barrier between the plasma and cerebrospinal fluid formed by the choroid plexus. These barriers can prevent certain substances (mostly harmful). ) from the blood into the brain tissue.
Although focused ultrasound combined with microbubble technology has shown effective efficacy in clinical practice, it also needs experiments to confirm its feasibility.
In any case, this is also a new idea and a hope for cure, bringing the dawn of life to Alzheimer's patients and their families.
Luteolin, alias carotenoid, carotenol, phytoalexin, riboflavin, marigoldin and phytoalexin, etc., orange-yellow powder. Natural lutein is an excellent antioxidant. Lutein and zeaxanthin are the only 2 carotenoids in the eye, and the prevention of vision loss and blindness caused by age-related retinal macular degeneration is the unique function of lutein.
Natural lutein is an excellent antioxidant, can resist free radicals in the body caused by cell and organ damage, thus can prevent the body aging caused by cardiovascular sclerosis, coronary heart disease and tumor disease.
