Difference between apraxia and dyspraxia

Can somebody tell me the difference between apraxia and dyspraxia? The SLP said my son had one of those. I thought she said apraxia but when i researched it I wasn't sure which one she had said and he doesn't go back to her until next week. He also has autism and SPD. but he has a speech disorder that they said is one of those 2 and he also has other motor movement problems but i wasnt sure. He misprounces lots of words and replaces letters he can see for other words and he has problems with his mouth movements and is very clumsy and has problems with gross and fine motor skills.

Apraxia is the loss of physical ability to move purposely. Say for example, you want this water, but that would require you to grab it, which you cannot.

Dyspraxia is developmental and a neurological disorder. Brain messages to move your arm toward the water are not registered.

What I was told in Quebec (I say this because the terms in some things don't seem to be the same online in sites from the USA compared to those that are french Canadian or from Europe) is that Apraxia is motor skills and muscle tone affected on the face and around the mouth. It can make it difficult to properly chew food, drink from a bottle or a straw, articulate properly etc. It does not affect swallowing but swallowing can be difficult if you have a hard time keeping anything in your mouth. It can be seen in older children who still drool a lot, are hard to understand since their speech is not articulated (mumbled) and you can even see the corners of their mouth and cheeks kind of droop.

Dyspraxia (my son suffers from it) is a neurological disorder affecting gross and fine motor skills, organisation of movements required to do tasks like walk, jump, fill up a cup, draw etc. It also affects any organisation required to do anything. Like homework, hygiene, games etc. Muscle tone/strength can also be affected even though there is no apparent muscle dystrophy. Like my son is 7. He is very tall and built for his age. His shoulders are wide, his legs are thick, he wears a size 10-12. You even see some muscle definition on his back and shoulders. However his strength is very weak. His balance is weak, he has a very hard time with endurance during sports. He tires very easily. He also had the symptoms of Apraxia as a baby but it was called dyspraxia since his entire body is affected not only his mouth and face.

That is what I was thought by his OT. Like I said though many sites don't explain it the same way.

Ok. Thanks!

Apraxia and Dyspraxia are basically the same thing. Research Apraxia- because there is more information out there with that term. The treatment is the same.
Apraxia is acquired from a stroke, head trauma, brain injury
Dyspraxia is developmental in nature.
With Apraxia/Dyspraxia muscle strength and coordination is affected. It can range from mild to severe. And any muscle group or a range can be affected.

I have 3 boys. 2 for sure have Dyspraxia. My oldest is mild/moderate. He receives speech therapy.
My middle son is very severe. He is affected in his gross motor, fine motor, oral and verbal skills. I hope this helps.
