Summary
Depression and cognitive change associated with menopause frequently occur, but are poorly understood. This research will allow for a greater understanding of the nature of the relationship between menopause, depression and cognitive impairment. The exploration of the efficacy of hormonal and antidepressant treatment on both mood and cognition will contribute to a better understanding to allow for improved treatment options.

Summary
Fragile X syndrome is one of the commonest genetic forms of mental retardation. The abnormal gene is passed from mothers to their sons or daughters, on their X chromosome. The gene abnormality is unstable, tending to worsen each time it is passed on. But if this gene abnormality is passed from fathers to their daughters, it does not worsen. Therefore, grandfathers of the affected children on their mother's side, as well as the mothers, may carry a mildly abnormal gene (a premutation), insufficie ....Fragile X syndrome is one of the commonest genetic forms of mental retardation. The abnormal gene is passed from mothers to their sons or daughters, on their X chromosome. The gene abnormality is unstable, tending to worsen each time it is passed on. But if this gene abnormality is passed from fathers to their daughters, it does not worsen. Therefore, grandfathers of the affected children on their mother's side, as well as the mothers, may carry a mildly abnormal gene (a premutation), insufficient to cause mental retardation. However, it has recently been discovered that these grandfathers may develop a syndrome (FXTAS) of tremor, incoordination, slowness of movements and mild dementia in their later years. Women were thought to be protected, as they carry TWO X chromosomes, one of which is normal even if the other has a premutation. But very recent reports suggest that they may also develop the FXTAS syndrome, as well as early menopause. This study aims to see how common and severe these abnormalities are in women who carry the premutation, using clinical, MRI and electronic measurements, and to relate the abnormalities to the severity of the gene malfunction and familial predisposition.Read moreRead less
The Micro-structural Basis Of Bone Loss And Fragility After Menopause: A Longitudinal Co-twin Control Study

Summary
Every woman becomes postmenopausal. Not all lose bone or sustain fractures after menopause. We will identify women who lose bone and those who don't and so identify women at risk for fracture so that they can be targeted for treatment and identify those who do not need to be treated. This will be done by measuring bone structure and how strong the bone is using a new, safe, quick technology that can be used in clinical practice
LKB1 - The Link Between Obesity And Breast Cancer In Postmenopausal Women

Funding Amount
$292,216.00
Summary
Obesity is a worldwide epidemic affecting 60% of Australians and is linked to many diseases including breast cancer. Changes in sex hormone levels during menopause may cause these diseases. The focus of this proposal is to determine the role of the sex hormones to regulate a protein (LKB1) involved in both fat metabolism and cancer. This research will benefit the ageing population by making a contribution toward generating therapeutics to combat obesity and breast cancer.
Adjunctive Hormone Therapy For Treatment Resistant Depression In Perimenopausal Women

Funding Amount

Summary
Women entering the menopause have increased rates of treatment resistant depression with poor response to standard antidepressant treatment. We propose to conduct a clinical trial of a novel adjunctive hormone, tibolone, to improve the outcomes for middle – aged women with severe depression.
InterLACE: International Collaboration For A Life Course Approach To Reproductive Health And Chronic Disease Events

Summary
Cardiovascular disease and diabetes are major chronic diseases among women. This world-leading research combines data from 7 international and 3 Australian studies of womenÍs health. We will investigate the relationship of reproductive health, from menarche to menopause, with the risk of Type 2 diabetes and cardiovascular disease in later life. Findings will support the development of policies and preventive health strategies to reduce the risk of these chronic diseases.
Female fertility and age at menopause are determined by the number and quality of eggs stored in the ovaries. For unknown reasons, two-thirds of all eggs die soon after they are made. Furthermore, a serious side effect of cancer treatment is egg death resulting in infertility and early menopause. I am unravelling the genes involved in determining whether an egg will live or die. This understanding will help us develop novel strategies to preserve fertility during aging and cancer treatment.
