A progressive decline in mental capability is because of degeneration of brain tissue,
- Age: Generally common among adults
- Genetics: Sometimes runs in families
- Gender, Lifestyle: Not Significant factors
Alzheimer’s disease is the general cause of dementia. Occasionally, younger people are affected by the disease. The underlying cause of the tissue destruction is unidentified, even though genetic factors might be complicated.
Alzheimerr’s and Dementia
Alzheimer’s disease is a degenerative disease of the brain that results in dementia. The terms Alzheimer’s and Dementia are often used interchangeably, but they are two distinct concepts with many differences between them. Alzheimer’s is the most common cause of dementia – in fact, almost two–thirds of dementia cases are due to Alzheimer’s disease. Alzheimer’s disease is the most common cause of mental decline, or dementia. But dementia has many other causes. Dementia is a broader term than Alzheimer’s and refers to any brain syndrome resulting in problems with memory, orientation, judgment, executive functioning, and communication. Although some kinds of memory loss are normal parts of aging, the changes due to aging are not severe enough to interfere with the level of function.
Dementia is a syndrome characterized by:
- impairment in memory
- impairment in another area of thinking such as the ability to reason and organize thoughts, the ability to use language, or the ability to see the visual world accurately.
Sometimes, dementia is caused due to multiple medical conditions. In these cases, it is often called as “Mixed dementia.” The most common form of mixed dementia is due to both Alzheimer’s and vascular disease.
Many different diseases can cause dementia, but Alzheimer’s disease is by far the most common cause for dementia in the United States and in most countries in the world.
