PBA:
Three cardinal components are dysphagia, dysarthria, and emotional apathy.

They can be described in the stages of
Shock (swallowing and speech defect)
Loss of function (difficulty in breathing)-spirometric assessment showed reduced vital capacities and lung volumes, and
Release of function (emotional incontinence).
Loss of cerebellar modulation (cortico-pontocerebellar pathways) causing emotional dysmetria and disinhibition owing to lesions of corticobulbar volitional pathways are the main pathogenesis explained for pseudobulbar apathy.

My husband’s doctor thinks he may have PSP which is also rare but would explain his jerking and balance issues

I just read about it, have never heard of it before but I'm pretty sure Ed does not have anything like that. I'm sorry you are dealing with that ❤️💜

I'll look it up and see...

English please....
