WHAT CAUSES ALS

The cause of ALS is unknown, but we do know that it can strike any adult at any time.

While the usual age at onset is between 45 and 65, people as young as 16 have been diagnosed. One-third of ALS Ontario clients are under the age of 45.

Males and females are affected almost equally, with a slightly higher percentage of males diagnosed with ALS. 

People of all ethnicities and social strata may be affected. 

Between five and 10 per cent of ALS cases are inherited, meaning that they are “familial” and are definitely linked genetically. In most cases, an ALS diagnosis is sporadic and we don’t know how it is caused.  Many researchers believe ALS is the product of multiple factors.
