Lewy body dementia (LBD) is an umbrella term for two similar and common subtypes of dementia:dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). Both are characterized by changes in thinking,movement,behavior,and mood. The two conditions have similar features and may have similar causes,and are believed to belong on a spectrum of Lewy body disease that includes Parkinson's disease. As of 2014,they were more often misdiagnosed than any other common dementia.
The following outline is provided as an overview of and topical guide to neuroscience:
Lewy bodies are the inclusion bodies –abnormal aggregations of protein –that develop inside neurons affected by Parkinson's disease (PD),the Lewy body dementias,and some other disorders. They are also seen in cases of multiple system atrophy,particularly the parkinsonian variant (MSA-P).
Paul Greengard was an American neuroscientist best known for his work on the molecular and cellular function of neurons. In 2000,Greengard,Arvid Carlsson and Eric Kandel were awarded the Nobel Prize for Physiology or Medicine for their discoveries concerning signal transduction in the nervous system. He was Vincent Astor Professor at Rockefeller University,and served on the Scientific Advisory Board of the Cure Alzheimer's Fund,as well as the Scientific Council of the Brain &Behavior Research Foundation. He was married to artist Ursula von Rydingsvard.
Neuroprotection refers to the relative preservation of neuronal structure and/or function. In the case of an ongoing insult the relative preservation of neuronal integrity implies a reduction in the rate of neuronal loss over time,which can be expressed as a differential equation.
A neurodegenerative disease is caused by the progressive loss of neurons,in the process known as neurodegeneration. Neuronal damage may also ultimately result in their death. Neurodegenerative diseases include amyotrophic lateral sclerosis,multiple sclerosis,Parkinson's disease,Alzheimer's disease,Huntington's disease,multiple system atrophy,tauopathies,and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry,ranging from molecular to systemic.Because there is no known way to reverse the progressive degeneration of neurons,these diseases are considered to be incurable;however research has shown that the two major contributing factors to neurodegeneration are oxidative stress and inflammation. Biomedical research has revealed many similarities between these diseases at the subcellular level,including atypical protein assemblies and induced cell death. These similarities suggest that therapeutic advances against one neurodegenerative disease might ameliorate other diseases as well.
β-Methylamino-L-alanine,or BMAA,is a non-proteinogenic amino acid produced by cyanobacteria. BMAA is a neurotoxin. Its potential role in various neurodegenerative disorders is the subject of scientific research.
Brain mitochondrial carrier protein 1 is a protein that in humans is encoded by the SLC25A14 gene.
John Quinn Trojanowski was an American academic research neuroscientist specializing in neurodegeneration. He and his partner,Virginia Man-Yee Lee,MBA,Ph.D.,are noted for identifying the roles of three proteins in neurodegenerative diseases:tau in Alzheimer's disease,alpha-synuclein in Parkinson's disease,and TDP-43 in Amyotrophic Lateral Sclerosis (ALS) and frontotemporal degeneration.
Gladstone Institutes is an American independent,non-profit biomedical research organization whose focus is to better understand,prevent,treat and cure cardiovascular,viral and neurological conditions such as heart failure,HIV/AIDS and Alzheimer's disease. Its researchers study these diseases using techniques of basic and translational science. Another focus at Gladstone is building on the development of induced pluripotent stem cell technology by one of its investigators,2012 Nobel Laureate Shinya Yamanaka,to improve drug discovery,personalized medicine and tissue regeneration.
Moussa B. H. Youdim is an Israeli neuroscientist specializing in neurochemistry and neuropharmacology. He is the discoverer of both monoamine oxidase (MAO) B inhibitors l-deprenyl (Selegiline) and rasagiline (Azilect) as anti-Parkinson drugs which possess neuroprotective activities. He is currently professor emeritus at Technion - Faculty of Medicine and President of Youdim Pharmaceuticals.
The Krembil Research Institute,formerly known as the Toronto Western Research Institute,is an academic medical research institute in Toronto. It is one of the largest research institutes in Canada focusing on human neurological disease.
Virginia Man-Yee Lee is a Chinese-born American biochemist and neuroscientist who specializes in the research of Alzheimer's disease. She is the current John H. Ware 3rd Endowed Professor in Alzheimer's Research at the Department of Pathology and Laboratory Medicine,and the director of the Center for Neurodegenerative Disease Research and co-director of the Marian S. Ware Alzheimer Drug Discovery Program at the Perelman School of Medicine,University of Pennsylvania. She received the 2020 Breakthrough Prize in Life Sciences.
The neuroscience of aging is the study of the changes in the nervous system that occur with ageing. Aging is associated with many changes in the central nervous system,such as mild atrophy of the cortex that is considered non-pathological. Aging is also associated with many neurological and neurodegenerative disease such as amyotrophic lateral sclerosis,dementia,mild cognitive impairment,Parkinson's disease,and Creutzfeldt–Jakob disease.
Carl Wayne Cotman was an American neuroscientist. He was a professor of neurology at the University of California,Irvine School of Medicine,where he was also the founding director of the Institute for Brain Aging and Dementia and the Institute for Memory Impairments and Neurological Disorders. He is known for researching the neurochemistry of Alzheimer's disease and other forms of dementia. His research has shown,for example,that physical exercise increases production of brain-derived neurotropic factor,which protects neurons from aging-related damage and promotes the growth of new ones. Cotman died in August 2024.
Melanie Crombie Williams Campbell is a professor of physics at the University of Waterloo. Cross-appointed with the School of Optometry and Vision Science,she is known for the development of light activated treatments for eye disease and non-invasive imaging techniques for the detection of Alzheimer's disease through the identification of retinal amyloids.
Elizabeth Mary Claire Fisher is a British geneticist and Professor at University College London. Her research investigates the degeneration of motor neurons during amyotrophic lateral sclerosis and Alzheimer's disease triggered by Down syndrome.
