Q

the cause is unknown while the treatment may be palliative the disease incurable.

most patient suffer from this type of parkinsonism

hypothesis of neuronal loss might be cause by toxins and exposure to free radicals

may cause by the drugs, including Dopamine antagonist such as Phenothiazines, Butyrophenones and Reserpine

Caused by poisoning from chemicals or toxins such as CO heavy metals and MPTP

Q

other symptoms occurs, not generally present in PD, and vary based on the specific form of the Parkinson’s plus syndrome.

6 common forms are:
Multiple system atrophy (MSA)
Progressive supranuclear palsy (PSP)
Cortibasal syndrome (CBS)
Dementias w/ Lewy bodies (DLB)
drug- induced parkinsonism
vascular parkinsonism (VP)

also referred to as “atypical parkinonism or parkinson’s plus syndrome”
