Ganzflicker: Using light-induced hallucinations to predict risk factors of psychosis
Rhythmic flashing light, or “Ganzflicker”, can elicit altered states of consciousness and hallucinations, bringing your mind’s eye out into the real world. What do you experience if you have a super mind’s eye, or none at all? In this talk, I will discuss how Ganzflicker has been used to simulate psychedelic experiences, how it can help us predict symptoms of psychosis, and even tap into the neural basis of hallucinations.
From the guts to the brain through adaptive immunity in the prevention of Alzheimer’ disease
Dr. Pasinetti is the Saunders Family Chair and Professor of Neurology at Icahn School of medicine at Mount Sinai, New York. His studies allowed him to develop novel therapeutic approaches through investigation of preventable risk factors including mood disorders in the promotion of resilience against neurodegenerative disorder. In his presentation Dr. Pasinetti will discuss novel concepts about the gut-brain axis in mechanisms associated to peripheral adaptive immunity as therapeutic targets to mitigate the onset and the progression of Alzheimer’s disease and other form of dementia.
Biopsychosocial pathways in dementia inequalities
In the United States, racial/ethnic inequalities in Alzheimer's disease and related dementias persist even after controlling for socioeconomic factors and physical health. These persistent and unexplained disparities suggest: (1) there are unrecognized dementia risk factors that are socially patterned and/or (2) known dementia risk factors exhibit differential impact across social groups. Pursuing these research directions with data from multiple longitudinal studies of brain and cognitive aging has revealed several challenges to the study of late-life health inequalities, highlighted evidence for both risk and resilience within marginalized communities, and inspired new data collection efforts to advance the field.
The Role of Cerebrovascular Pathology in Aging and Neurodegenerative Disease Populations
Late-life cognitive impairment and dementia are heterogeneous and multifactorial conditions driven by a combination of genetic, vascular, and lifestyle-related factors. More than 75% of patients with dementia have evidence of cerebrovascular pathology at autopsy. Cerebrovascular disease lesions can be detected on structural MRI and used as biomarkers to determine the extent of cerebrovascular pathology. These biomarkers are associated with cognitive difficulties and increase the risk of dementia for the same level of neurodegenerative pathology. Given that some of the risk factors for cerebrovascular disease are potentially modifiable, identifying the role of cerebrovascular pathology in aging and neurodegenerative disease populations opens a window for prevention of cognitive decline and dementia.
Epigenetics and Dementia: Lessons From the 20-Year Indianapolis-Ibadan Dementia Study
Dementia is of global interest because of the rapid increase in both the number of individuals affected and the population at risk. It is essential that the risk factors be carefully delineated for the formulation of preventive strategies. Epigenetics refers to external modifications that turn genes "on" or "off”, and cross-cultural studies of migrant populations provide information on the interplay of environmental factors on genetic predisposition. The Indianapolis-Ibadan Dementia Study compared the prevalence, incidence and risk factors of dementia in African Americans and Yoruba to tease out the role of epigenetics in dementia. The presentation will provide details on biomarkers of dementia, vascular risk factors and the association with apolipoprotein E in the Yoruba. The purpose will be to inspire early career researchers on possibilities and research strategies applicable in African populations
