No, it's great to be here.
Thank you.
No, you are, you are on target.
And at this point in his decline, I think it is just very easy for people to identify without any type of understanding of why.
Um, and that's one of the reasons why I talk about this on my channel.
Concussion talks that SLP is because like there are reasons why.
So with that question, I actually want to separate out twitches and glitches because there's two different things going on.
And then when they occur at the same time, there's a reason.
so the twitches are something likely that they're likely something that's called myoclonus and a myoclonus is going to be a brief burst of an involuntary muscle movement so that's where you see kind of the arm go out the shoulder go up kind of whatever what's happening within the brain networks is that the brain is supposed to be regulating and suppressing unwanted motor movements
if you think about kids they're all over the place their brains haven't developed enough to do this and then kind of as we age and the brain declines it comes back so the frontal lobe should be suppressing unwanted motor movements like those twitches that's called inhibitory control or disinhibition but what happens is as brain decline and dementia
It damages the circuits.
We have this like excitatory, go do this, inhibitory stop.
Then we have what's called cortical excitability.
This is a lot of neuroscience, but it's basically just the neurons are very hyper excitable.
And that results in these sudden muscle contractions that are unwanted.
yeah so the word glitch that has to do with where the brain's energy is going the brain's energy is going to the glitch the glitch is its own separate issue a language difficulty phonemic paraphrasia so because the brain is already struggling to suppress these movements now all of a sudden it's putting a lot more effort to this speech because there was an error and it has to think how do i correct this or how do i get out of this situation the twitches happen more frequently
So everyone's going to be in the same situation to some degree.
If you're taking that math problem, for example, you might notice that like, you're like doing this with your pencil and not recognizing it or your foot's tapping or something like that.
So you might have those so-called unwanted or unplanned movements.
but they're not happening to the point where in the middle of speaking, which while it is difficult, is not that difficult.
