Why is Carbidopa admistered with L-Dopa?
L-Dopa is a prodrug used to treat Parkinson's Disease. It crosses the blood brain barrier with the aid of Phe-Trp-L-aromatic acid transporters and is then turned into dopamine through decarboxylation. However, it is also capable of producing large amounts of dopamine in peripheral areas by stimulating the chemoreceptor trigger zone and these dopamine can produce side effects in peripheral body parts. Carbidopa is hence added to inhibit DOPA decarboxylase in peripheral areas so that there will be fewer of these side effects.
Are there any unpleasant long term side-effects from l-dopa consumption aside from potential hair loss?
Here are all the side effects, these will not occur in every individual.Can I note that although there are many adverse effects associated with L-DOPA, in particular psychiatric ones, it has fewer than other antiparkinsonian agents, such as anticholinergics and dopamine receptor agonists.The most unpleasant long-term side effects are the effects of chronic levodopa administration in the treatment of Parkinson disease, which include:End-of-dose deterioration of functionOn/off oscillationsFreezing during movementDose failure (drug resistance)Dyskinesia at peak dosePossible serotonin depletion: Recent studies have demonstrated that use of L-DOPA without simultaneously giving proper levels of serotonin precursors depletes serotoninPossible dopamine dysregulation: The long-term use of L-DOPA in PD has been linked to the so-called dopamine dysregulation syndrome.[4]source: wikipedia

Why did Dr. Say have to stop using the drog L-Dopa on the Frozen patients?
Dr. Say had to stop using L-Dopa on the Frozen patients because the drug led to severe side effects, including unpredictable and violent behavior in some individuals. Additionally, the treatment did not provide lasting benefits and resulted in complications that outweighed any initial improvements in motor function. This prompted a reevaluation of the risks versus rewards of continued use of L-Dopa in this unique patient population.
How long does L-dopa therapy work?
L-dopa therapy usually remains effective for five years or longer
How l-dopa works in cns?
L-dopa is a precursor to dopamine and is used in the treatment of Parkinson's disease. In the central nervous system, L-dopa crosses the blood-brain barrier and is converted into dopamine by dopa decarboxylase in the brain. This helps to increase dopamine levels in the brain, which can alleviate the motor symptoms of Parkinson's disease.

Are there any unpleasant LONG-TERM side-effects from L-DOPA consumption aside from potential hair loss?
Yes there are. Long-term use of Levodopa to treat Parkinson's disease may cause fluctuations in therapeutic effects in such a way that the symptoms might be worse. We call this motor fluctuations. Usually motor fluctuations appear after a few years of regular use of L-Dopa (this is why patients with a young-onset Parkinson's disease are usually given dopaminergic agonists first instead of L-Dopa/carbidopa; doctors want to prevent motor fluctuations to appear). Symptoms of motor fluctuations may include severe dyskinesia when serum L-Dopa reaches its peak level; and gradual, foreseeable loss of therapeutic effects after a few hours. This results in patients with marked bradykinesia and resting tremor without medication, and choreo-athetosic dyskinesia when L-Dopa is given. When a patient reaches motor fluctuations, his or her disease becomes more difficult for physicians to control. For more info, please consult your physician or pharmacist.
