A study finds out that high levels of homocysteine make a patient with Parkinson’s disease more likely to suffer from depression.
We already know that elevated levels of the amino acid homocysteine are a risk factor for dementia and Alzheimer’s disease. And high levels are also linked to impaired cognition, even if people don’t actually have dementia. Those with Parkinson’s disease are at risk of elevated homocysteine because of the drugs they take.
