A saliva test carried out by doctors may be able to both diagnose Parkinson’s and detect the severity of the condition, according to a recent study published in medical journal ‘Neurological Sciences’.

Several indicators of the development of Parkinson’s, including problems in the production of energy, can be easily detected in saliva.

As part of the study, carried out by a team from the All India Institute of Medical Sciences, New Delhi, India, saliva samples were collected from 76 patients living with Parkinson’s, and 37 participants with good general health.

They found that the saliva of those with Parkinson’s reflected evidence of alteration in neurotransmitters – chemical messengers that allow nerve cells to communicate.

The researchers said the test “may highlight the characteristic changes in metabolite levels during the onset of Parkinson’s”.

Parkinson’s Europe co-founder Lizzie Graham wins World Parkinson Coalition award

Parkinson’s Europe co-founder Lizzie Graham has won a World Parkinson Coalition (WPC) award for her contribution to the Parkinson’s community. Lizzie is one of four people set to receive the Robin Elliott Award – which is given out every three years to individuals whose efforts best embody the goals and ethos of the WPC. She will be presented with the award in a ceremony at the World Parkinson’s Congress, which will be held in Barcelona later this year. Commenting on the news of Lizzie’s award, Parkinson’s Europe President, Veronica Clark, said: “Lizzie is Lizzie, and we love her for who she is and what she has done for us all – for people with Parkinson’s past and present and, I’m sure, future.” Lizzie co-founded the European Parkinson’s Disease Association (renamed Parkinson’s Europe last year) in 1992. She has since held several roles within the organisation – including secretary general and…

Study explores predictors of cognitive impairment in Parkinson’s disease

Cognitive impairment can affect some people with Parkinson’s – and may greatly impact their quality of life. Now, researchers in China have examined the possible risk factors for cognitive impairment in those with the condition. The study analysed data from 409 people with Parkinson’s within two years of their involvement in the Parkinson’s Progression Markers Initiative (PPMI) – an international study that follows people with and without the condition over time. The participants, who were newly diagnosed and experiencing normal cognitive function at the start of the research, were studied for at least five years. Published in ‘Frontiers in Aging Neuroscience’, the results indicate that older age at onset, high blood pressure and worse baseline motor symptoms may be among factors that could contribute to an increased risk of developing cognitive impairment. The researchers cautioned that “a larger sample and much more comprehensive assessment, and prolonged follow-up, will be required”.

Could frailty be a potential risk factor for Parkinson’s disease?

Frailty can refer to a reduction in physical function, and its attributes – including a slow walking speed and weak grip – are commonly experienced by people with Parkinson’s. Until now, there has been limited insight into the link between frailty and the risk of developing the condition over time. This is what led researchers at the Huazhong University of Science and Technology in China to analyse data from a large UK study, which was gathered over a 12-year period. Published in JAMA Neurology, the analysis found that frailty may be linked to an 87% higher risk of developing the condition. Commenting on the results, the researchers said: “These findings indicate that physical frailty is a potential risk factor for [Parkinson’s], and the assessment and management of frailty might have clinical significance in the at-risk population.”
