Summary
The aim of this study is to determine which factors influence forgetting in typically developing children and in children with epilepsy. Specifically, we want to establish how forgetting occurs over time and whether it is influenced by other cognitive/thinking skills, such as strategies used to remember information, attention or resistance to interference. Moreover, we are interested in whether retention rates are affected by different types of learning materials (i.e. visual versus verbal).

Summary
Within the next 5 - 10 years it is likely that sophisticated combination pharmacotherapy for Alzheimer's disease will become available. Once intervention agents are available that affect the underlying disease process, it will be critical to accurately identify those patients who are in the earliest stages of cognitive decline. That is, failure to detect cognitive decline at an early stage will reduce the effectiveness of the intervention and be costly to the individual and society.

Once intervention agents are available that affect the underlying disease process, it will be critical to accurately identify those patients who are in the earliest stages of cognitive decline. That is, failure to detect cognitive decline at an early stage will reduce the effectiveness of the intervention and be costly to the individual and society. At the same time, the probability of falsely identifying an individual as having Alzheimer's disease needs to be reduced in order to avoid unnecessary testing, anxiety and distress, and expense. A sophisticated and highly flexible testing system to detect the earliest stages of memory impairment will be developed. The test will be administered over the web in a general practitioner's surgery enabling the collection of normative data on the population of greatest interest (elderly patients seeing their doctor). Voice recognition technology will be used in order to insure a user friendly environment. Stringent procedures to protect privacy will be employed. The test will be inexpensive and easy to take and will allow valid retesting so that it can be used as part of the routine health screening for the elderly. This will be a far more sensitive and specific indicator of the cognitive decline found in most neurodegenerative disorders such as Alzheimer's disease, and will enable general practitioners to be more confident in assessing their older patients. It will also reduce costly referrals by more accurately identifying those patients at risk. It is expected that the test will find acceptance amongst patients and their doctors and become a routine part of normal health screening for the elderly.Read moreRead less
Determining The Cognitive Sequelae Of Adolescent Cannabis Use: A Longitudinal Cohort Study.

Funding Amount
$259,731.00
Summary
Adult cannabis users have problems with memory and attention, but it is not known to what extent these cognitive deficits relate to premorbid intellectual functioning or underlying personality features. Further, it is not known to what extent cannabis use during adolescence (when the brain is still developing), may lead to greater cognitive impairment. This study will directly address these questions utilising a large sample of adolescents followed since entry to high school.
The Missing Link: MGluR5 As A Therapeutic Target For Cognitive Decline In Dementia

Funding Amount

Summary
Cognitive decline is a core feature of Alzheimer’s Disease (AD), yet there is no cure or treatment. Recent evidence suggests that a protein called mGluR5 could cause brain cells to lose function, leading to memory loss. This project will investigate whether disrupting mGluR5 function can improve cognition in mice with genetic AD. Memory will be assessed in mice using innovative touchscreen tests that closely mimic the tests used in humans.
IRAP inhibitors are currently being developed as a new class of drugs for treating dementia and other forms of memory deficits. However, there are still gaps in our knowledge about how these drugs act to improve memory. The experiments outlined in this proposal will provide important insights into the drug action in different mouse models of memory deficit.

Summary
Traumatic brain injury (TBI) resulting from motor vehicle accidents and other mishaps is a leading cause of death and disability in young adults. Memory problems is one of the most common and debilitating symptoms reported by people with TBI. Traditionally, the treatment of memory problems has focussed on retrospective memory or the ability to recall or recognise previously learned information (e.g., remembering the name of a person, recalling the content of yesterday's news stories).

Memory problems is one of the most common and debilitating symptoms reported by people with TBI. Traditionally, the treatment of memory problems has focussed on retrospective memory or the ability to recall or recognise previously learned information (e.g., remembering the name of a person, recalling the content of yesterday's news stories). Little research has been conducted on problems with another type of memory called prospective memory or the ability to remember to do something in the future (e.g., remembering to attend an appointment, remembering to pay a bill before its due date). The treatment of prospective memory problems in people with TBI is, however, very important for assisting them to return to work and successful integration into the community. This is because the ability to remember to do things at the right time is essential for work and for independent living. In addition, failure to treat this type of problems can be risky or even life threatening (e.g., forgetting to take medication, forgetting to turn off an electrical appliance). This project aims to evaluate the independent and combined effectiveness of two rehabilitation strategies, namely, promoting awareness of memory problems and adopting compensatory strategies. In addition, this project aims to gauge whether a better management of prospective memory problem will lead to better functioning in the community.Read moreRead less

Summary
The transition from home to a residential aged care facility (RACF) is a potentially traumatic process that has a negative impact on the health and well-being of both people with dementia and their caregivers.

This project will develop an intervention program for people with dementia that maximizes their ability to learn and retain functional skills and that enhances the communicative competence of both people with dementia and their carergivers. This will serve to minimize the stress and disorientation, as well as accompanying increased risk of illness, of entering residential care. We will investigate whether this intervention program has good outcomes both for the people with dementia as well as their caregivers. The research will develop guidelines for the development of best-practice policies for service providers and the government, which will assist both health workers and homebased caregivers to better manage the transition of people with dementia from home to the RACF environment.Read moreRead less
BDNF Genotype And Emotional Memory In Post-traumatic Stress Disorder

Summary
This project addresses the question of why some people develop PTSD following trauma and others don’t. It will assess the influence of genetics (specifically a genotype that influences Brain Derived Neurotrophic Factor) on emotional memory processes as distressing emotional memories are a core symptom of PTSD. If we find that people with a particular genetic profile have a greater risk of developing intrusive memories after trauma, this will help us better target treatment for those individuals.

Adolescence is also a period when the brain undergoes significant structural and functional change, and there is growing evidence that the brain may be particularly vulnerable to the effects of addictive substances during this developmental stage. There is increasing evidence that long term or heavy use of cannabis impairs learning and memory. It is thought that the continued bombardment of the brain s own natural cannabis-like neurotransmitter system by the active chemicals within cannabis disrupts critical aspects of brain function. This research seeks to improve our understanding of the way that cannabis use affects memory and how these problems might develop or worsen from adolescence to adulthood. This project will investigate memory processes in cannabis users using functional brain imaging techniques. This will allow identification of regions of the brain that are not working efficiently when cannabis users attempt to memorise and recall words from a list and recognise patterns. The project will examine how different levels of cannabis use (long term vs. short term and heavy vs. light) may affect brain function during learning and memory, and determine if the observed memory problems depend upon the age at which cannabis use began and the gender of the user. The findings from this research will substantially contribute to our understanding of the ways in which cannabis use affects brain function and potentially triggers serious psychiatric disorders, such as schizophrenia. The findings will contribute to guidelines regarding hazardous levels of cannabis use within adolescent and adult populations, and will inform debate, policy, education and treatment.Read moreRead less
