Dementia01:30

Dementia

113
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Next-generation Sequencing03:00

Next-generation Sequencing

88.8K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Genomics

36.3K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome-wide Association Studies-GWAS

13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

484
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Area of Science:

  • Neurodegenerative diseases
  • Genomics and transcriptomics
  • Data science in medicine

Background:

  • Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia, characterized by severe neuropsychiatric symptoms.
  • Known genetic variants (e.g., SNCA, GBA, APOE) and transcriptomic signatures (e.g., synuclein aggregation, neuroinflammation) offer partial insights into DLB pathology.
  • Current understanding is incomplete, leading to a lack of disease-modifying treatments and diagnostic biomarkers.

Purpose of the Study:

  • To review the current genomic and transcriptomic understanding of DLB.
  • To identify gaps in the existing literature regarding DLB molecular pathology.
  • To explore the potential of data science methods in advancing DLB research and treatment.

Main Methods:

  • Review of existing genomic and transcriptomic studies in DLB.
  • Analysis of identified genetic variants and transcriptomic signatures.
  • Discussion of data science approaches, including machine learning and multi-omic data analysis.

Main Results:

  • Genomic studies identified associations with variants in SNCA, GBA, APOE, SNCB, and MAPT.
  • Transcriptomic analyses revealed signatures related to protein aggregation, neuroinflammation, and mitochondrial dysfunction.
  • Significant gaps remain in understanding DLB molecular pathology.

Conclusions:

  • Data science methods, including whole-transcriptome analysis and machine learning on multi-omic data, hold promise for uncovering novel DLB signatures.
  • Genomic prediction could enable early case identification and timely treatment.
  • Advancing DLB understanding through data science is crucial for developing effective therapies and biomarkers.
