Alzheimer’s Disease – In this article, we will try to provide a brief Alzheimer’s disease introduction and answer some questions like “What is Alzheimer’s disease?” and “What is Dementia?”.
Alzheimer’s disease is the main cause of dementia
Alzheimer’s Disease, Firstly we’ll describe what dementia is? Dementia is a progressive dysfunction of the brain caused by a head trauma or a disease. In dementia, patients lose their cognitive functions progressively. Cognitive functions include our learning, thinking, reasoning, spatial orientation, memory and reasoning abilities. Many diseases can cause dementia but the most prominent and common one is Alzheimer’s disease.
A German physician Alois Alzheimer identified Alzheimer’s disease in 1907. He lectured about a woman who had experienced the early smptoms a couple of years previously. Alzheimer’s Disease, Her symptoms were impaired memory, cognitive decline, and difficulty understanding talks and questions. In advanced stages she became unable to care herself in her daily life. After her death Alois Alzheimer performed an autopsy on her brain and investigation showed the cerebral cortex to be thinner than normal. He described dense deposits around the neurons (neuritic plaques) and the presence of twisted bands of fibers (neurofibrillary tangles) inner side of the neurons.
Alzheimer’s disease is a condition which gradually destroys our neurons (brain cells)
This process is named neurodegeneration. It characterized clinically with a cognitive decline. The disease primarily effects the cerebral cortex and the hippocampus which are the parts of the brain. While cerebral cortex is involved in the higher functions of the brain like thinking, reasoning, decision making, moving and sensation, hippocampus is associated with memory and learning.
Alzheimer’s Disease, The human brain has approximately 100 billion neurons and 100 trillion synapses connects neurons to each other. In Alzheimer’s disease, the neurons in cerebral cortex and hippocampus progressively do not able to fulfill their functions because of the numerous reasons and in the course of time they will be lost.
