Summary
Alzheimer’s disease is the most common type of dementia but often has multiple mixed pathologies. For example, Alzheimer post mortem brains may have abnormal accumulation of Lewy bodies in certain parts of the brains, and could be diagnosed as Lewy body disease. This may represent a skewed representation of some dementia subtypes. This project will identify the biological determinants of dementia patients with Lewy body disease for better understanding and future therapeutic targeting.
Dementia Related Deficits In Striatal Cholinergic Function And Decision-making

Summary
This proposal will provide essential new information on the role of deficits in decision-making associated with Parkinson’s disease dementia. We will use an innovative animal model to assess the influence of neurodegeneration and neuroinflammation the consequent loss of function in the neuronal systems supporting the learning and memory processes that contribute to goal-directed action, particularly the way new learning interacts with existing memory to guide choice and decision-making.

Summary
Neurocognitive decline in Parkinson's disease refers to the non-motor symptoms of the disease; these symptoms have increasingly become recognised as both prevalent, and evolving early in the disease course. While motor symptoms are treated with drugs and electrodes, the changes to patients� cognition, the progressive dementia, the psychosis and other symptoms progress with poor treatment. This research is designed to identify and understand targets so better treatments can be created.

Summary
Trauma in the adult mammalian central nervous system causes long-lasting functional deficits. The resulting physical and financial burdens to the individual, to his or her family, and to the community at large, are immense. When fibre tracts are damaged there is disruption of circuits and there may be death of associated nerve cells. Interventions are therefore necessary to promote repair and to try to restore function. Highly modified, non-harmful viruses can be used as vectors to introduce gen ....Trauma in the adult mammalian central nervous system causes long-lasting functional deficits. The resulting physical and financial burdens to the individual, to his or her family, and to the community at large, are immense. When fibre tracts are damaged there is disruption of circuits and there may be death of associated nerve cells. Interventions are therefore necessary to promote repair and to try to restore function. Highly modified, non-harmful viruses can be used as vectors to introduce genes into cells, a method that allows targeted supply of molecules to the injured brain. Gene and cell therapy may eventually be of clinical benefit to injured patients. In a range of different experiments we will combine two different gene therapy approaches, various pharmacological agents and novel transplantation strategies in attempts to enhance the survival of affected nerve cells and promote the regrowth of damaged nerve fibres across injury sites in the injured adult rat visual system. Long-term vector-mediated expression of growth factors in neurons and in grafts may 'trap' regenerating axons, potentially reducing their outgrowth into distal, denervated target areas. It is therefore important to determine if temporal regulation of growth-promoting genes has additional beneficial effects on the ability of regenerating neurons to recognise and selectively regrow axons into appropriate CNS targets. An additional series of studies will thus be undertaken. We will test a new generation of regulatory vectors in which it is possible to switch the virally encoded genes on or off and thus control the level and timing of gene expression over a therapeutic range. We will then determine if the use of these regulatory viral vectors results in more consistent and robust growth of nerve fibres with better reconnections, in the longer term leading to better recovery of function.Read moreRead less
