Traumatic brain injury 'increases Parkinson's risk'

Posted on 22 August 2011

Traumatic brain injury increases the risk of Parkinson's disease, according to a new study.

Researchers observed a 15 per cent drop in nigrostriatal dopaminergic neurons following a traumatic brain injury on the study conducted on mice.

Moreover, after 26 weeks, there was a total 30 per cent decrease in these neurons, as the effect continued for some time after the brain injury had occurred, according to the study by University of California Los Angeles scientists.

Additionally, when traumatic brain injury was combined with the risk factor of pesticides, this 30 per cent drop was reached much faster.

Symptoms characteristic of Parkinson's disease such as rigidity, postural tremor and akinesia are linked to a lack of the neurons.

Meanwhile, University of Toronto research has found that the benefits of deep brain stimulation could last as long as a decade after surgery for those with Parkinson's disease.
