Brief Biography

Dr. Smith received a PhD in Clinical Psychology from McGill University in 1985. She received clinical and research training at the Montreal Neurological Hospital and Institute, and at the Montreal Children's Hospital. She is a professor in the Department of Psychology at the University of Toronto Mississauga. She has been a member of the Neuropsychology section of the Diagnostic Strategies Commission of the International League against Epilepsy, and a member of the steering committees of the Canadian Pediatric Epilepsy Network and the University of Toronto Epilepsy Research Program.

Research Interests

Behavioural and neuropsychological correlates of central nervous system dysfunction during development.

Research Activities

Over the past several years, Dr. Smith's major area of research has been on the cognitive and behavioural co-morbidities associated with epilepsy. Her work has addressed these topics from a number of perspectives, including the clinical nature of intractable epilepsy, and theoretical issues for understanding early brain dysfunction. The work also contains important implications for clinical treatment decisions and expectations for the impact of treatments. These studies have involved individuals with intractable seizures with onset in childhood, although different projects had targeted individuals of different ages, ranging from 6 to 30 years. Much of this work has been conducted in a collaborative context with colleagues from neurology, psychology, nursing, and social work. The studies have addressed four major areas: quality of life, surgical outcome, plasticity of language representation, and memory.

In another line of research focused on determining the nature, frequency and correlates of psychological impairment arising from infection with the human immunodeficiency virus (HIV), Dr. Smith is monitoring the developmental, behavioural and cognitive status of children born with HIV. She is also investigating the development of children who have in utero exposure to antiretroviral drugs.
