Alzheimer’s disease is an all too common disease which is believed to be caused by excessive deposition of amyloid protein in the brain. Some researchers have questioned the amyloid hypothesis of Alzheimer’s Disease. Several studies have reported that drug treatment to lower brain amyloid brain deposits are not useful in preventing or reversing Alzheimer’s disease.
Brain inflammation and immune activation may play a major role in Alzheimer’s. Infection with fungi and bacteria may also play a major role in the development of Alzheimer’s Disease. A recent study of brains found fungal growth in the brains of 11 of 11 patients who died of Alzheimer’s Disease but in 0 of 10 patients who died of a cause other than Alzheimer’s Disease (p<0.001).
Confocal microscopic immunofluorescence studies have reported that fungi was frequently found in the blood vessels and capillaries of Alzheimer’s patient’s brains but not from the brains of other patients. The authors concluded that since many Alzheimer’s Disease patients have brain fungal infections, and many antifungal treatments have relatively low toxicity- antifungal treatment should be tried in Alzheimer’s Disease patients to see if it might be helpful.
