Debbie, I have been diagnosed with Type B PD. Like you, I have a hard time finding much info regarding it. Actually most of the info seems to be originated by Dr. Robert Iacono and his associates and trainees. I think it may just be a way he has devised to differentiate between the various types of PD. Before I was diagnosed, I had no idea there were more than one type. You're right, akinetic means lack of movement. As it was explained to me, as my disease progresses I will suffer more from rigidity of my limbs rather than tremors. I have a very slight tremor in my right hand that is pretty much controlled with meds. It is only visible when I am very stressed or fatigued. I also fairly often feel what I can only explain as an internal tremor. My hand doesn't shake, but I can feel it shaking on the inside. My neuro said that is very common with my kind of PD. I don't know where to point you for more info. But you might speak with your Mom's dr and see what he/she has to say about it.
