What Is Dementia?
Dementia is an umbrella term for memory, language, problem-solving, and other cognitive abilities that are severe enough to interfere with daily functioning. The most prevalent cause of dementia is Alzheimer’s.
The Indicators and Symptoms of Dementia
The manifestations of this disease can vary considerably. Examples include
Many conditions are progressive, meaning that the symptoms begin slowly and progressively worsen.
If you or someone you know is experiencing memory problems or other changes in cognitive abilities, you should not disregard them.
See a Neurologist immediately to ascertain the cause. An expert evaluation may uncover a treatable condition. And even if symptoms suggest dementia, early diagnosis enables a person to maximize the benefits of available treatments and provides the opportunity to participate in clinical trials or research.
It also affords the opportunity to plan for the future.
Causes
It is caused by brain cell injury. This injury interferes with brain cells’ ability to communicate with one another. When brain cells cannot communicate normally, thinking, behavior, and emotions may be affected.
Each region of the brain is responsible for a particular function, such as memory, judgment, or movement. Damaged cells in a region prevent that region from performing its functions ordinarily.
Various forms of dementia are associated with distinct types of brain cell damage in specific brain regions. In this disease, for instance, excessive levels of certain proteins inside and outside of brain cells make it difficult for brain cells to remain healthy and communicate. The region of the brain known as the hippocampus is the brain’s learning and memory hub, and its brain cells are frequently the first to be injured. Consequently, memory loss is frequently one of the earliest signs of Alzheimer’s.
While the majority of changes in the brain are permanent and worsen over time, thinking and memory difficulties may improve if the following conditions are treated or addressed:
Identification
There is no single test that can definitively diagnose dementia. Doctors diagnose Alzheimer’s disease and other forms of dementia based on a thorough medical history, a physical examination, laboratory tests, and the characteristic mental and behavioral changes associated with each type.
A person’s dementia can be diagnosed with a high degree of certainty. However, it is more difficult to determine the precise type of dementia because different dementias’ symptoms and cognitive changes can overlap.
In some instances, a physician may diagnose “dementia” without specifying a subtype. If this occurs, a specialist such as a neurologist may be required.
