Dr. Giliberto’s approach to Medicine, Neurology and Alzheimer’s disease has always been dual: basic research and clinical practice. He has worked and collaborated with great scientists, such as Massimo Tabaton, George Perry, Mark Smith, Pierluigi Gambetti, Antonio Uccelli, Luciano D’Adamio and Peter Davies. The work with Dr. D’Adamio at Albert Einstein College of Medicine, lead to identify APP processing modulators, including ITMB2 (BRI2). At the Feinstein Institutes, Dr. Giliberto collaborates with a diverse range of excellent scientists, expanding the focus of his research to tau, microglia and the immune response, cell cycle and the treatment of tau pathology with engineered antibodies.

Dr. Giliberto works with patients affected by Alzheimer’s disease and other dementias, providing clinical care and trials, helping them and their families to cope with the disruption that this disease brings to their lives.

This dual role has allowed him to broaden his view of the disease, as the inspiration he receives from patients at every encounter is invaluable.

Dr. Giliberto teaches clinical neurology to medical students, Neurology, Medicine and Psychiatry residents at Hofstra University and North Shore University Hospital, and trains MD/PhD and PhD students in the laboratory at the Feinstein Institutes.

Dr. Giliberto graduated summa cum laude at the University of Milano Medical School, in Italy, completed his Neurology residency at the Medical school of Genova, Italy and at North Shore University Hospital, Northwell-Hofstra. He obtained his PhD in neuroscience from the Medical school of Genova, Italy while doing research at the Albert Einstein College of Medicine.

Dr. Elizabeth Allison is an Internal Medicine Resident Physician in New York City. Dr. Allison and her family have seen firsthand the impact of dementia on the patient and family as her dad was diagnosed with Lewy Body dementia in December 2021 at age 57. Her dad is an engineer by trade and an IT professional who worked at Northwell for many years until his diagnosis. The diagnosis of dementia came as a shock to him and their entire family, given his age, lack of pre-existing health conditions, and overall well-being.
Dr. Allison’s discussion will focus on her perspective as a daughter, young physician, and caregiver. She will also share perspectives from her family members on their adjustment to this new reality. This session hopes to leave the audience with tools and insight for navigating the nuances of a diagnosis of dementia.
