A neurological disorder characterized by an inability to perform basic learned movements, such as walking or dressing oneself, despite being physically able to carry them out and wanting to perform them. Sometimes children have this issue, but it does affect all ages.
Here are a few symptoms to look for in your child if you think they might have apraxia:
As a younger child you should look for a lack of cooing or gurgling as a baby, latent speech (both late and missing important bits), issues with sound combination, subbing easier words for more difficult ones/deleting sounds that are harder to make, and difficulty eating.
When your child gets older you might begin to notice sound issues with words that do not have to do with their maturity level in any way, the fact that the child understands but cannot easily respond verbally, noticable effort to make sounds because they lack the ability to control the mouth area, problems with larger words, issues with speech during periods of anxiousness or anxiety, and the fact that the child is difficult for others to understand.

Example: An elderly patient has good sensation and motor strength, but seems unable to remember how to feed himself.
