Does parkinson's disease usually cause many symptoms?

Tremors: Muscle wasting, cramping, weakness.

Further Detail......: Physical symptoms can include tremor of limbs at rest>in posture or in action; slow movements & stiff (rigid) muscles causing quiet facial emotions, softer voice, bent forward head & neck posture, decreased arm swing, slow-shuffled walk, small/scratchy penmanship, etc. Non-physical symptoms can include cognitive decline, depression, anxiety, sleepiness, constipation, ed, low bp, acting-out dreams.

But, Rx Available!!!: Dopamine meds are mainstay of treatment. Modern therapy recommends longer lasting, milder potency meds first: Azilect (mao-b selective inhibitor) & Dopamine agonists (requip xl/mirapex er/neupro). After they've been maximized & stronger meds are needed to adequately manage symptoms, then sinemet +/- Comtan (stalevo (carbidopa and levodopa and entacapone) is both together) are begun. Tailor rx with side effects in mind for each person.
