Alzheimer's disease may be infectious, study suggests


Disturbing possibility raises questions about certain surgical procedures

The “seeds” of Alzheimer’s disease may be transmitted from one person to another during certain medical procedures, scientists have found.

A study into people who died of a separate kind of brain disease after receiving injections of human growth hormone suggests that Alzheimer’s may also be a transmissible disease.

The findings have raised questions about the safety of some medical procedures, possibly including blood transfusions and invasive dental treatment, which may involve the transfer of contaminated tissues or surgical equipment.

The investigation has shown for the first time in humans that Alzheimer’s disease may be a transmissible infection which could be inadvertently passed between people.

Scientists emphasised that the new evidence is still preliminary and should not stop anyone from having surgery. They have also stressed that it is not possible to “catch” Alzheimer’s by living with someone with the disease.

However, the findings of a study into eight people who were given growth hormone injections when they were children have raised the disturbing possibility that Alzheimer’s can be transmitted under certain circumstances when infected tissues or surgical instruments are passed between individuals.
