MND on Guam

In the 1940s and 1950s, the incidence of motor neurone disease on the western Pacific island of Guam was much higher than elsewhere in the world. The disease did not seem to be inherited or contagious - no virus could be found. A possible explanation was the islander's habit of using cycad seeds to make flour. These are poisonous if not washed properly.

Seeds from the false sago palm have been linked to motor neurone disease on the pacific island of Guam.
