According to Parkinson's Disease Foundation, the term “parkinsonism” is a generic descriptive term that refers to the whole category of neurological diseases that causes slowness of movement. The category includes the classic form of Parkinson’s disease, many atypical variants, sometimes called “Parkinson’s Plus Syndromes,” and any other brain disease that resembles Parkinson’s, such as hydrocephalus or drug-induced parkinsonism.

In all cases of parkinsonism, no matter the cause, there is a disturbance in the dopamine systems of the basal ganglia — a part of the brain that controls movement. In all cases, this dopamine deficiency leads to the characteristic combination of tremor, slowness, rigidity and postural instability.

Classic (idiopathic) Parkinson’s is the most common and most treatable form of parkinsonism. For a significant minority, about 15 percent of all persons with parkinsonism, one of the atypical variants may be present. These conditions are more serious and less treatable than classic PD, and include diseases such as:

multiple system atrophy (MSA)
progressive supranuclear palsy (PSP)
corticobasal degeneration (CBD)
Lewy body dementia (LBD)

I have seen four neurologist in the three years since my diagnosis. Tried six different medications. Later this month I’ll see what I hope is the last neurologist. Continuity of care will be welcome.
I have no tremors but significant issues with trying to walk and balance issues.
I’m in a power chair 98% of my day. Been taking Rytary for several months.
Can not say it actually does any good. Other symptoms include emotional
High and lows, constipation , weakened immune system, insomnia
My voice is weaker, and lost my ability to write legibly.

Nothing is simple , all the meds work with your brain chemistry! Some good , some bad!

Parkinsonism is an atypical Parkinson's. There may be many symptoms of Parkinson's but there are other symptoms that don't mimic a typical Parkinson's. It includes : LBD which stands for LEwy Body Dementia. If you google LBD it will go over several features that are different. There are others that fall into that but I can't recall them right off but you should find relatively easy by googling the word 'Parkinsonism. I hope I was helpful.

I have no good answers yet, but am so grateful for the knowledge and friendships I have gained from this support group. Thank you
