Homocysteine and Parkinson's disease symptoms
Part of Brain & nervous system clinical trials.
This study looks at whether a substance in your blood called homocysteine relates to Parkinson's symptoms. If you join, you will have a blood test and assessments to help understand this link.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 40 years of age or older.
- You have been diagnosed with Parkinson's disease by a movement disorder specialist.
- Your Parkinson's symptoms are not caused by another condition such as infection, medication, poisoning, or head injury.
- You do not have another brain disease like multiple system atrophy, progressive supranuclear palsy, or dementia with Lewy bodies.
- You did not have significant memory or thinking problems before your Parkinson's started, and you have no major brain lesions on MRI.
- You are not taking certain medications that affect homocysteine levels (like some seizure or cancer drugs) and you do not have thyroid or kidney problems.

This trial tests whether controlling homocysteine levels can help people with Parkinson's disease who are taking levodopa. You may qualify if you take at least 300 mg of levodopa per day, are between 40 and 90 years old, and have no major kidney problems or uncontrolled high blood pressure.
This study measures blood biomarkers (measurable substances in blood) in people with Parkinson’s at different stages. It may help doctors understand how Parkinson’s changes over time and could guide future testing or treatments.
This study is testing whether a simple blood test can help doctors better understand Parkinson's disease by looking at how a protein called alpha-synuclein behaves. It aims to find a new way to diagnose and track the disease.
This trial tests if taking daily amino acid supplements helps people with Parkinson's disease. You need to be on stable Parkinson's medication for at least 3 months.
This study looks for new markers in the blood or other samples to help diagnose Parkinson's disease earlier. It compares people with Parkinson's, related conditions (like multiple system atrophy or progressive supranuclear palsy), and healthy volunteers to find differences.
This study looks for a new blood marker that could help doctors detect Parkinson’s disease earlier. Depending on your diagnosis and treatment status, your blood may be compared with other people’s to see how well the test works.
