Latest research summary

 

Studying the effects of ecstasy on the brain – RG23 (45KB)

 

Principal investigator: Dr Paola Piccini
Start date: November 2003  
Completion date: October 2006
Award: £80,344 


The aim of this study was to test the hypothesis that people who take ecstasy repeatedly have problems with the function of nerve cells that produce serotonin or dopamine (types of chemical messengers in the brain).

 

The results from this study may suggest that the dopamine system is not functioning properly in former ecstasy users. However, more research needs to be carried out to examine what the long-term effects may be.

 

 

 

What causes Parkinson's

 

Understanding the role of the protein UCH1 in Parkinson's disease - RG20 (48KB)

Seven changes in the UCH-L1 gene,which is involved in the inherited form of Parkinson's, were uncovered.

 

Identifying and understanding the genetic causes of Parkinson's - RG18 (55KB)

Two new genes know as PINK1 and LRRK2  that play a role in Parkinson's, were identified. This research follows from the project described in RG11.

 

Understanding nerve cell death in Parkinson's disease - RG14 (71KB)

The effects of normal and abnormal forms of the gene known as parkin on nerve cell death, were evaluated. They found that the normal form protects cell from dying while the abnormal form accelerates nerve cell death.

 

Involvement of glycine receptors in Parkinson's disease - RG12 (94KB)

The findings of this research provide further evidence linking glycine receptors (elements that receive electrical stimuli in the brain) to the processes involved in the development of Parkinson’s and the associated death of nerve cells.


Identifying genes involved in Parkinson's disease - RG11 (74KB)

New techniqueswere developed to assess the genes associated with Parkinson’s. This paved the way for subsequent identification of two new genes that are associated with Parkinson's (see RG18).

 

Involvement of glial cells - RG08 (70KB)
This project looked at establishing whether the abnormal activity of the support cells that surround nerve cells in the brain leads to nerve cell death.


A novel neuroprotective strategy in Parkinson's disease - RG05 (67KB)
A selection of drugs were assessed to see whether they protect nerve cells from death.


Role of parkin in Parkinson's disease - RG02 (66KB)
New techniques were develped that enabled the researchers to look at the role of proteins that are involved in Parkinson's (e.g. parkin) during nerve cell death.

 

 

Improved treatments / Cure

 

Replacement of the dopamine-producing nerve cells lost in Parkinson's - RG21 (337KB)

The initial results are promising. These showed that some of the neural stem cells (grown in the laboratory) are able to develop into the dopamine-producing nerve cells that are lost during Parkinson's. Interestingly, however, cells grown in the laboratory for long periods of time (20 weeks) did not survive when placed into the brain.  

 

Developing a source of neurons to replace the nerve cells lost in Parkinson's - RG19 (93KB)
What makes stem cells become dopamine-producing nerve cells was the focus of this project


The effect of dopamine replacement therapy on behaviour -
RG17 (86KB)
This summary discusses the results of research that looked at the effects of taking excessive dopamine replacement therapy on behaviour in people with Parkinson's


The role of inflammation in Parkinson's disease - RG16 (128KB)
An imaging techniquewas developed that measured the level of inflammation in the brain of people with Parkinson's. Inflammation may be present in the region of the brain affected in Parkinson's


Neuroprotective effects of the protein superoxide dismutase - RG09 (70KB)

This study investigated whether a protein known as superoxide dismutase can prevent or decrease the level of nerve cell death


Repetitive transcranial stimulation in Parkinson's - RG03 (76KB)

A study into whether a slow train of magnetic impulses applied to the brain can improvethe uncontrollable movements associated with long-term treatment with levodopa

 

 

Care and support

 

Control of language in people with Parkinson's RG22 (360 KB)

The researchers have shown that Parkinson’s may influence various mental tasks required for conversation. This is discussed in more detail in the summary.

 

Quality of life of children whose parent has Parkinson's disease - RG15 (47KB)
A questionnaire that measures the impact of Parkinson's on the quality of life of children whose parent has Parkinson's was designed and evaluated.


Attentional training in Parkinson's disease - RG13 (84KB)
A computer-based training program to improve attention in people with Parkinson'swas developed during this study.


Voice, speech and swallowing problems in Parkinson's disease - RG10 (70KB)
The impact of voice, speech and swallowing problems in people with Parkinson'sis discussed in this research summary.


An evaluation of service need and availability for younger people - RG07 (72KB)
Establishing which services (e.g. physiotherapy) are important to the younger person with Parkinson's and the benefits of early referral, were the focus of this research.


Effects of functional electrical stimulation on gait in Parkinson's Disease - RG06 (102KB)
Electrical stimulation of a nerve in the leg of people with Parkinson's improved gait features such as heel strike and stride length.


Methods of controlling the rate of speech in people with Parkinson's RG04 (272KB)
The effectiveness of two methods of controlling fast speech in people with Parkinson's, were compared.


Cognitive Behavioural Therapy for Carers - RG01 (76KB)
This research focussed on reducing the level of distress in carers of people with Parkinson's.
