Epilepsy is often poorly controlled by medication and dietary measures can be taken that reduce occurrence of epileptic seizures. Glucose control is impacted by diet and also mutations in the genes that move glucose around the body are known to cause epilepsy. Here we will be studying how the genetic and dietary control of glucose levels impacts brain function to increase seizures and to potentially reveal novel therapies.
Brain damage resulting from long-term alcohol abuse is localized to discrete regions of the brain and selectively impairs key neuropsychological functions. Alcohol misuse affects processes that control excitability in the brain, leading to the over-stimulation of brain cells. When this continues for long periods the cells are likely to die and most alcoholics misuse alcohol for most of their adult lives. We will study the human brain s capacity to use and respond to glutamate, its major natural ....Brain damage resulting from long-term alcohol abuse is localized to discrete regions of the brain and selectively impairs key neuropsychological functions. Alcohol misuse affects processes that control excitability in the brain, leading to the over-stimulation of brain cells. When this continues for long periods the cells are likely to die and most alcoholics misuse alcohol for most of their adult lives. We will study the human brain s capacity to use and respond to glutamate, its major natural excitant, in the regions that are selectively damaged by alcoholism. How these capacities are affected by heredity, and by diseases commonly associated with alcoholism such as cirrhosis of the liver, will also be explored. If we can understand how selective brain damage occurs in alcoholics we will be better able to devise new drug therapies to combat and prevent it. As well, localized brain damage is a feature of many neurological diseases, so the study will provide a general model of disease mechanisms.Read moreRead less
My research focuses on understanding pathobiological mechanisms in acute and chronic neurodegenerative conditions such as stroke and Parkinson’s disease which have large burdens on the community through health care costs and on families because of the lack of effective treatments. An improved understanding of how brain cells die and of how the most abundant brain cell, the astrocyte, can be engineered to be a resource for regenerative medicine offer promise for improved clinical management.
