In the 1980’s, American researcher Dr. Alan Macdonald found the first evidence that a spirochaete (type of bacteria) was involved in Alzheimer’s dementia. The spirochete in question was Borrelia, a microbe which causes Lyme Disease and Relapsing Fever in humans, as well as a number of animal diseases.

Dr. Macdonald spent several decades researching this connection. He found the specific DNA of Borrelia in 7 out of 10 autopsy brain specimens from Alzheimer’s victims. Using state-of-the-art Molecular Beacon technology, he found the Borrelia DNA in the hippocampus (Alzheimer-associated memory centre of the brain). Moreover, he found the DNA precisely at the sites which are notorious pathological hallmarks of Alzheimer’s Disease – the plaques (round diseased areas of brain tissue), and the sites of Granulovacuolar degeneration.

Working independently from Dr. Macdonald, Swiss researcher Dr. Judith Miklossy also found Borrelia in specimens of autopsy Alzheimer brains. In addition, she found other spirochaetes belonging to the genus, or bacterial sub-type, of Treponema. These bacteria inhabit the mouth and are responsible for dental and gum infections.

A person may become infected with Lyme Disease Borrelia from the bite of a tick, a tiny blood-sucking eight-legged creature which can be as small as a poppy seed. Ticks are found in most rural areas, especially wooded, bracken, or marshy terrain – but they can even be found in urban parks and back gardens. As the bite is painless, and tiny ticks may hide in the armpit, scalp, or other spots secluded from view, people often do not realise they have been bitten. A round ring-shaped or target-shaped rash at the tickbite site is a hallmark of Lyme disease, but often does not occur. Lyme borreliosis symptoms may begin weeks to months later.

Often all that is experienced at first is a flu-like illness, but later a huge range of symptoms may develop, as the bacteria disseminate and start to impact every system in the body. Crushing fatigue, meningitis, heart and joint problems, blurred vision, sensitivity to noise and touch, limb weakness, memory and concentration problems are just some of the myriad symptoms that may appear. The best chance for cure of Borreliosis is early and adequate antibiotic treatment. Once established, the disease may become chronic and very difficult to cure.

In Africa, relapsing fever Borreliosis is a huge scourge, with some patients relapsing even after treatment. Though traditional relapsing fever is considered rare today in the West, new strains of Borrelia are being discovered all the time – some of which are undetectable on the Lyme antibody tests commonly in use.

More research is needed into the Alzheimer-spirochaete connection. It is known that some Lyme disease patients, even in the chronic stage, have had their memory and other problems reversed after specialised treatment by experts in the disease. We believe this information must be made available to doctors and to the general public.
