What is lytico-bodig?

Table of Contents

Lytico-bodig is the local name for a complex of neurological diseases (or diseases that affect the nervous system) on Guam that resembles amyotrophic lateral sclerosis (ALS or Lou Gerhig’s disease), Parkinsonism-Dementia (PD) and possibly Alzheimer’s disease.

What did the Chamorro of Guam people call the disease?

Lytico-bodig (also Lytigo-bodig) disease, Guam disease, or amyotrophic lateral sclerosis-parkinsonism-dementia (ALS-PDC) is a neurodegenerative disease of uncertain etiology endemic to the Chamorro people of the island of Guam in Micronesia.

Why is ALS higher Guam?

The changing ecology and socioeconomic conditions in the past 40 years in Guam might have contributed to the drastic reduction in the environmental risk factors. However, the incidence remains high during the past decade, which suggests their genetic predisposition to Guam ALS.

How common is familial ALS?

Inheritance. About 90 to 95 percent of ALS cases are sporadic, which means they are not inherited. An estimated 5 to 10 percent of ALS is familial and caused by mutations in one of several genes.

What is BMAA used for?

The neurotoxin β-N-methylamino-l-alanine (BMAA) is suspected to play a role in the neurological diseases amyotrophic lateral sclerosis, Alzheimer’s disease, and Parkinson’s disease.

What is BMAA found in?

The amino acid BMAA was first isolated and identified in extracts from the seeds of cycad trees in the West Pacific island of Guam in 1967. BMAA was potentially linked to the neurodegenerative diseases that were prevalent in Guam during the 1950’s, as an important environmental risk factor.

Is lytico bodig disease the same as ALS?

Lytico-bodig disease. Lytico-bodig disease, sometimes spelled Lytigo-bodig, is the name of a disease in the language of Chamorro. It is referred to by neuroscientists as amyotrophic lateral sclerosis-parkinsonism-dementia (ALS-PDC), a term coined by Asao Hirano and colleagues in 1961.

What can we learn from Keck’s monograph on lytico-bodig?

The story of lytico-bodig has largely focused on the medical or clinical aspects of the disease and rarely on the individuals who suffered from it, although Keck’s monograph, which included interviews with patients and their family members, represents a welcome remedy to this trend.

What is Lytigo-bodig disease?

Lytico-bodig (also Lytigo-bodig) disease, Guam disease, or amyotrophic lateral sclerosis-parkinsonism-dementia ( ALS-PDC) is a neurodegenerative disease of uncertain etiology endemic to the Chamorro people of the island of Guam in Micronesia. Lytigo and bodig are Chamorro language words for two different manifestations of the same condition.
