Development of novel methods for early detection, and non-pharmacological treatments of cognitive decline during aging
Dr. Hudon is a neuropsychologist who develops approaches to better diagnose and treat disorders that occur most often in the elderly population, such as mild cognitive impairment and Alzheimer's disease. Early detection increases the likelihood that a change in lifestyle and certain treatments may delay the progression of the disease, significantly improving the quality of life of people affected.
Dr. Hudon uses and tests neuropsychological assessment and magnetic resonance imaging methods to detect Alzheimer's disease early. He also studies the role of depressive and anxiety symptoms as well as the contribution of sleep difficulties in predicting the cognitive decline that leads to Alzheimer's disease.
The treatments developed by Dr. Hudon aim to improve cognitive functioning and reduce depressive and anxiety symptoms as well as sleep difficulties for people at risk of developing Alzheimer's disease. Among the treatments developed and tested by this researcher are physical activity, mindfulness meditation, psychotherapy and cognitive training.
Overall, Dr. Hudon's research will lead to slower cognitive decline as we age and delay the onset of Alzheimer's disease.
My research interests pertains to neuropsychological assessment as well as the early diagnosis and prevention of cognitive decline in elderly people.
