Scientists say that almost half of all dementia cases could be prevented if these and other risk factors could be eliminated from our lives.
Dementia, a general term for loss of memory, language, problem-solving and other thinking abilities, has no cure to date. However, with advances in science and based on symptoms, doctors have devised various ways to treat this degenerative condition.
Public health interventions to address critical risk factors for the disease could save up to £4 billion a year, according to a new study. These figures come as uncorrected vision loss and factors linked to high cholesterol have been added to the list of possible causes of dementia.
Scientists say that almost half of all dementia cases could be prevented if these and other risk factors could be eliminated from our lives.
How does vision loss affect brain health??
Wearing glasses could help prevent a new risk factor for dementia, according to research published in The Lancet. Scientists say two percent of cases could be linked to uncorrected vision problems.
Vision loss affects the parts of the brain that process visual information, resulting in difficulty understanding vision and judging distance and color. Many people also have reduced sensitivity to contrast and depth perception and have difficulty detecting motion. Other symptoms include distortions, sensitivity to light, visual hallucinations, and difficulty identifying objects and faces.
Experts recommend regular eye exams, corrective lenses and protecting your eyes from injury, which can help maintain eye health.
What is dementia??
Dementia involves a decline in mental function from a previously higher level that is severe enough to interfere with daily life. According to doctors, a person with dementia has two or more of these specific difficulties, including a decline in:
- Memory
- Reasoning
- Language
- Coordination
- Cheer up
- Behavior
Dementia develops when parts of the brain involved in learning, memory, decision-making, or language are affected by infections or diseases. The most common cause of dementia is Alzheimer’s disease.
What causes dementia??
Dementia is caused by damage to the brain that affects nerve cells and destroys the organ’s ability to communicate with its different areas. Dementia is also caused by blocked blood flow to the brain, which deprives it of necessary oxygen and nutrients. Without oxygen and nutrients, brain tissue dies.
Brain damage causes different symptoms, depending on the area affected. According to doctors, some dementias are not reversible and get worse over time, while others are caused by other medical conditions that also affect the brain. Another group of health problems can cause symptoms similar to those of dementia.
Many of these conditions are treatable and the symptoms of dementia are reversible.
