Lesley Kennedy, MSW

Interim Program Director

Lesley E.  Kennedy brings a wealth of experience to her position as the Care Manager for the Center of Excellence for Alzheimer’s disease.  Beginning her career working in skilled nursing facilities as a CNA Lesley learned early that she loved working with individuals with a diagnosis of dementia and their family systems.  Lesley gained her License of Practical Nursing which allowed her to gain further experiences working as a charge nurse on Dementia Units and as an office nurse in a rural primary care practice.  Seeing the need for advocacy regarding this population Lesley again returned to academia to advance her knowledge base attaining a Bachelor’s Degree in Health and Human Services with a special concentration in social gerontology and finally a Master’s Degree in Social Work from SUNY Buffalo.    All of these experiences combined well allowing Ms. Kennedy to function at various levels in the medical and aging services fields.  Some positions Lesley has held are Medical Social Worker, Health Service Administrator for the Seneca Nation Health System, Screener/Liaison for a Neurosciences Center of Excellence, Program Director for the Alzheimer’s Association of Western New York and most recently Director of the Seneca Nation Area Office for the Aging.  Lesley plans to use all of the knowledge, skills and experiences she has gain throughout three decades of work to enhance the vital work of the UB Center of Excellence for Alzheimer’s disease.  ​

When it comes to Alzheimer's disease and dementia, a drug that can completely stop or prevent the disease is the greatest hope of patients, family members and health care providers. This is what our patients at the UB Alzheimer's Disease and Memory Disorders Center tell us repeatedly and what patients all over the globe are wishing for. Current therapies do help slow the progress of Alzheimer's disease, but finding the cure is a huge endeavor requiring collaboration between patients, caregivers, doctors, universities, pharmaceutical companies and funding agencies.

As part of the Jacobs School of Medicine and Biomedical Sciences and UBMD Neurology, the UB Alzheimer's Disease and Memory Disorders Center is able to confront this critical public health issue not only by treating patients but by researching new discoveries that will lead us closer to a cure for Alzheimer's and dementia. The ADMDC facilitates patient participation in clinical trials for promising new Alzheimer's drugs.

The ADMDC incorporates an active translational research program housed in the UB Clinical and Translational Research center and is affiliated with the prestigious Clinical and Translational Research Award. Dr. Szigeti has had external funding from the Alzheimer's Association and from the National Institute of Aging of the National Institutes of Health over the years. Her work focuses on the genetics of Alzheimer's disease, a very heterogeneous disorder with a strong genetic component. Analysis of the genetic background will enable better classification of disease subgroups that should then lead to new and more effective medications to either delay disease onset or prolong the earlier stage of the disease when symptoms are very mild and patients still function relatively well.
