Is there a connection between Parkinson's and Alzheimer's?
There is a probable theoretical link between the two conditions.
Parkinson's disease has many features in common with Alzheimer's disease: for instance there's an increased likelihood of dementia occurring in Parkinson's and the presence of extrapyramidal features, such as odd body movements, in Alzheimer's.
An association between these two conditions has been reported – especially within men who have early onset Alzheimer's.
In addition to this, there is a specific type of dementia called lewy body dementia that is similar to Alzheimer's but is distinct from it and is characterised by the same pathology seen in Parkinson's.
There is a typical appearance in parts of the brain of those with Alzheimer's called a neurofibrillary tangle and these are also found in Parkinson's.
There are stronger risks for Alzheimer's if there is a family history of it or Downs's syndrome.
It's quite a confusing area, and if you'd like to learn more about this, why not look on the Alzheimer's Society web site.
