Summary
Understanding the causes of epilepsies is essential for treatment and prevention. In many people with epilepsy the cause is not obvious and is frequently attributed to events at birth or minor head injuries. It is clear that these factors are generally not important. There is increasing evidence that subtle changes in brain structure, reflecting developmental or maturational abnormalities, may be the cause of these epilepsies. Such subtle changes can be detected by novel magnetic resonance imagi ....Understanding the causes of epilepsies is essential for treatment and prevention. In many people with epilepsy the cause is not obvious and is frequently attributed to events at birth or minor head injuries. It is clear that these factors are generally not important. There is increasing evidence that subtle changes in brain structure, reflecting developmental or maturational abnormalities, may be the cause of these epilepsies. Such subtle changes can be detected by novel magnetic resonance imaging strategies. However, due to individual differences of brain morphology, the significance of such subtle changes can be disputed. Monozygotic twins have an increased similarity of their brain morphology. Therefore, analysis of monozygotic twins where only one twin is affected with epilepy, is a powerful way to characterize significant brain abnormalities. This will provide novel information on the causes of epilepsy relevant to the general population.Read moreRead less
Brain Plaques And Cognitive Decline In The Elderly - A Study Of Human Twins

Summary
One hallmark of Alzheimer’s disease (AD) is a build up of plaques in the brain, starting years before symptoms are observed. We will use PiB-PET brain scans to determine the degree of plaque build-up in pairs of twins at risk of developing AD, and calculate the heritability of these plaques. We will also be able to calculate (potentially modifiable) environmental factors that may be contributing to the relationship between plaques and memory and thinking.
QTL Linkage Analysis For Complex Human Traits In Twin Families

Summary
This project will focus on finding genes for common human diseases. Now that the human genome has been sequenced, the race is on to find out what the estimated 38,000 human genes do and which ones are associated with which diseases. Scattered throughout the genome are small variations in DNA sequence, some of which increase the odds of disease while others are protective.
