10 ALS Symptoms
Symptom #9: Change in Behavior
The most noticeable symptoms of ALS are usually physical, with muscle weakness contributing to decreased mobility. Not all symptoms associated with ALS are physical, though. The patient may also be affected psychologically. Some behavioral changes are necessary because a decrease in mobility means patients need to make adjustments in their lives, but others are a direct result of cognitive changes.
Around half of all people with ALS will undergo additional cognitive changes. They may begin to think differently as well as act differently. About one in four ALS patients develop dementia.
