CBD is a compound found in the cannabis plant. Unlike another component, THC, CBD is non-addictive and doesn’t cause intoxication. This makes this research even more exciting as the existing information we have on CBD suggests it has no side effects.
Hallucinations and delusions
Around 75% of people with Parkinson's experience hallucinations and delusions and it can be distressing. This could include seeing people, hearing noises, or feeling the sensation of something that isn't there.
Charles was diagnosed with Parkinson's in 2009 and began to experience hallucinations in 2015.
Charles said of his experience:
"I began to see people and pet dogs. I saw my wife Michele - she died in 2009 around the time when I started to notice mild Parkinson's symptoms. Whenever she appeared and I reached out to touch her, she disappeared leaving behind a smile a bit like the Cheshire Cat"
How can cannabidiol affect Parkinson’s symptoms
Current treatments for hallucinations or delusions work by blocking dopamine receptors in the brain, which can make other symptoms of Parkinson’s, such as a tremor, worse. What's exciting about cannabidiol is that it seems to act in a different way without causing any other side effects. However, the clinical trial will determine how accurate this is for people with Parkinson's.
