Can ocd behaviors be symptoms of parkinson's disease?

No: I am not aware of any direct connection between the two two relatively common conditions can coexist.

Commonly, yes: Mood & behavior issues are often seen in parkinson's disease: depression, anxiety, apathy, obsessive thoughts & compulsive actions (hyper-sexuality, excessive buying, eating, gambling, hording, staying up late working on computer/craft/art projects & punding (cleaning, organizing, disassembling & reassembling mechanical devices). All can lead to missed meals/med doses, isolation, & decreased qol!

Clinical Facts: 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.
