A decrease or loss of the sense of smell is very common in patients with Parkinson's Disease even in the earliest stages of the disease. There have been no treatments that have been proven to improve sense of smell in patients with Parkinson's Disease.
Rasagiline (brand name: Azilect) was approved by the U.S. Food and Drug Administration (FDA) on May 16th 2006 to be used by Parkinson's patients to treat the motor symptoms associated with the disease. The purpose of this study is to see if there is change in sense of smell after starting Rasagiline.
This study will last approximately 10 weeks.
- 2 visits to The Parkinson's Institute in Sunnyvale, California
- 1 phone call between visits
You will be asked to take either Rasagiline (Azilect) or placebo (an identical pill without active ingredients)
- 5 in 6 chance of receiving Rasagiline (Azilect)
- 1 in 6 chance of receiving placebo
- Neither you nor the study team will know which you are assigned
- This information will be available in case of emergency
To be eligible for this study, you must:
- be 75 years old or younger
- have a decreased loss of smell or complete loss of smell
- have not taken Selegiline or Rasagiline previously
- have not smoked within the last year
- be on a stable dose of Parkinson's medication (or not on any PD medicines)
- have no history of head trauma, nasal surgery, nasal inflammation causing congestion or polyps, nasal/sinus infection, or prior Zicam use
- have not used decongestants, antihistamine or inhaled steroids within 2 weeks of the study and be willing to avoid such treatments during the study

A 2 phase study to evaluate disease progression in Parkinson's disease patients taking rasagiline
The objective of the study is to assess the effects of rasagiline on cognitive functions in patient with Parkinson's disease. Patients on any dopaminergic medications will be assigned to r...

Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form.

Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Parkinson's is a progressive neurological condition, affecting one person in every 500, 95% of which are over 40. It is caused by degeneration of more than 70% of the substantia nigra, which depletes the dopamine (the neurotransmitter involved in pro...
