A Primer on Alzheimer's Disease and the Brain

چکیده
The healthy human brain contains tens of billions of neurons, specialized cells that process and transmit information via electrical and chemical signals. Most neurons have three basic components: a cell body, multiple dendrites, and an axon. The cell body contains the nucleus, which houses the genetic blueprint that directs and regulates the cell’s activities. Dendrites are branch-like structures that radiate from the cell body and collect information from other neurons. The axon is a cable-like structure that extends from the other end of the cell body and transmits messages to other neurons.

Effect of Memantine on Expression of NAT-Rad18, Rad18 and Sorl1 Genes in Rat Model of Alzheimer\'s Disease
Background and Objective: Dysregulation of long-term expression of non-coding RNAs (lncRNAs) has a potential role in progressive brain disorders such as Alzheimer's disease. This study aimed to analyze the apoptosis and expression of 51A and NAT-Rad18 lncRNAs and their target genes in brain tissue and peripheral blood mononuclear cells (PBMCs) of the rat model of AD, before and after memantine ...

متن کاملThe role of genetics in alzheimer’s disease
Alzheimer's disease is a progressive neurological disorder that causes the brain to shrink (atrophy) and brain cells die. Alzheimer's disease is the most common cause of dementia and causes a decrease in thinking skills and social behaviors. Alzheimer's disease is more common in people over 65 years old. The risk of developing Alzheimer's disease and other types of dementia increases with age,...
متن کاملDetection of Alzheimer\'s disease based on magnetic resonance imaging of the brain using support vector machine model
Background: Alzheimer's disease (AD) is the most common disorder of dementia, which has not been cured after its occurrence. AD progresses indiscernible, first destroy the structure of the brain and subsequently becomes clinically evident. Therefore, the timely and correct diagnosis of these structural changes in the brain is very important and it can prevent the disease or stop its progress. N...
