Are Difficulty In Swallowing Food, Muscle Twitching, And Hoarseness Signs Of A Motor Neuron Disease Such As ALS?
ALS remains highly unlikely.

Hello and welcome back to HealthcareMagic.
I wouldn't be afraid of that test providing any indication of motor neuron disease (ALS). First of all in neurological conditions such as motor neuron disease the difficulty is more in swallowing liquids not with solid food as in your case.
In addition to that reading at that account there doesn't seem to be a paralysis, a weakness of the swallowing muscles in the throat due to the neuron damage (which would be the case in ALS), on the contrary it seems to show an increased tonus, an exaggerated activity increasing the pressure and causing the swallowing difficulty.
The time factor as you say yourself points against ALS as well, other areas are usually involved after a year.
As for the MRI, if chronic microangiopathic ischemic white matter changes, the scattered foci should be a sign of some concern in the long term in the sense that you should pay particular attention to vascular risk factors (high blood pressure, diabetes, smoking, high cholesterol, sedentary lifestyle etc) in order for such changes not to progress more rapidly in the future. Some changes are common as we age, but the issues I mentioned affect blood vessels and accelerate these changes. As for the small signal increase in the pons the MRI is unable to distinguish its cause, but still because it's not increased in size and doesn't enhance after contrast administration it means that it is not an active evolving process may have been there for years.
Whether these changes can cause dysphagia, in theory yes, but it's in much more advanced cases, in my opinion the size and quantity of these mild changes doesn't justify dysphagia. Furthermore again it would be more pronounced for liquids than food.
I remain at your disposal for other questions.
You're welcome. Glad to have been of help.
