Dementia is not a disease. Instead, it is a syndrome – a set of symptoms – that occurs when neurons in the brain stop working, lose contact with other brain cells, and die.
Eventually it loses its intellectual capacity, which is enough to disrupt a person’s daily life.
Dementia can range from mild to severe. People who are in the last stages are completely incapable of taking care of themselves and need help around the clock in the most basic aspects of daily life.
Half of all men and women aged 85 and over (sometimes called the oldest) have some form of dementia, yet experts do not consider it a normal part of aging. Are Many people retain their academic ability in the nineties.
The Elderly National Institute defines dementia in two parts.
Two or more basic functions that are weak. These functions include memory, language skills, visual perception, and the ability to pay attention and pay attention. Includes cognitive skills such as the ability to reason and solve problems.
Loss of brain function to such an extent that a person cannot perform normal daily activities.
Some people with dementia may be unable to control their emotions, or they may show personality changes.
They are deceptive (seeing or experiencing things that do not exist) and delusions (not really believing). (1)
Are Dementia and Alzheimer’s the Same?
Dementia and Alzheimer’s disease are not the same thing.
Alzheimer’s accounts for 60 to 80 percent of all dementia cases. It is a slowly progressive brain disease in the brain in which pieces of protein beta amyloid (rails) accumulate outside the neurons in the brain and twisted strands of protein tao (tangled) accumulate inside the neurons.
Early in the disease, people with Alzheimer’s may have difficulty remembering recent conversations, names, or events, and may experience numbness and depression.
Although Alzheimer’s is a very common dementia, it is not the only one.
The second most common form of dementia, for example, is vascular dementia, which occurs when a blocked artery blocks blood flow to the brain, forcing brain cells to work with oxygen and nutrients. ۔
Although memory loss is one of the first symptoms of Alzheimer’s, people with neuropathic dementia may initially have inability or unusual difficulty in making decisions, organizing and making decisions.
In the past, physicians used to diagnose vascular dementia and vice versa to diagnose Alzheimer’s. But now experts believe that both dementias often coexist, an example of a condition called mixed dementia.
An autopsy of people with Alzheimer’s found that about half had other forms of dementia, usually vascular dementia. (2)
A Tell-Tale Sign of Dementia: Proteins in the Brain
Dementia is caused by damage to brain cells. Researchers are trying to figure out why and how this happens. He hopes that their efforts will lead to better treatment. It doesn’t exist yet. Or a treatment that works more than relieving symptoms for a short time.
Scientists have observed an association between Alzheimer’s disease as well as certain types of dementia and high levels of protein in the brain.
Leukemia is the third most common form of dementia, involving abnormal deposits of a protein called alpha-synocline.
In a healthy brain, alpha synovial helps neurons communicate. But when the alpha synuclein, the so-called levy in the body, begins to slide inside the neurons, brain functions deteriorate, affecting thinking, movement, behavior and mood. (3)
A Syndrome With Many Causes — Some Preventable
Genes, which have been passed down from parents to their offspring, are thought to play a role in almost all types of dementia.
Yet except in rare cases of mutations in the same gene, people do not directly inherit dementia. Instead, their problems depend on a combination of genetic, environmental and lifestyle factors.
According to the Alzheimer’s Society of the United Kingdom, most people can significantly reduce their risk of dementia by staying physically active, eating a healthy diet, drinking moderately (if not at all) and not smoking. Are
Certain types of dementia appear to be more seriously affected by genetics. About 10 to 15% of people with one type of dementia have a family history. (4)
How Many People Suffer From Dementia?
An estimated 14% of people aged 71 and older live with dementia. Among them, women are more affected than men – 16% compared to 11%.
Unfortunately, dementia often remains undiagnosed and undiagnosed, with only half of those diagnosed with dementia being physicians.
The number of dementia sufferers is expected to increase significantly as child boomers age and progress in medicine. By 2030, an estimated 20 percent of people in the United States will be 65 and older, up from 14 percent in 2012.
The toll of dementia – personal, medical and social – is already very high, and with these changing demographics, it is expected to be much higher.
For 2017, the total cost of health care and long-term care for people with dementia was estimated at 25 259 billion. This amount is estimated to reach 1 1.1 trillion by 2050 ( 2017$). (2)
Medication Can Stabilize the Symptoms, Not Cure Dementia
When it comes to progressive diseases that cause dementia, there is currently no cure and there is no way to significantly slow down or reverse damage to the brain.
However, some medications can reduce or stabilize some symptoms of dementia for at least a short time. The Food and Drug Administration (FDA) has approved many people to treat Alzheimer’s disease, with clinical evidence that they can help people with other types of dementia.
For example, patients with leukemia may get some relief from the use of cholinesterase inhibitors, which are currently used to treat Alzheimer’s symptoms such as memory loss, confusion, and difficulty thinking and reasoning. (5)
There are currently more than 250 clinical trials in the United States testing for dementia. Investigators working with people in centers online and across the country are studying both pharmaceutical and non-pharmaceutical interventions.
Participants in these clinical trials, including those with dementia and those at risk, can access potential treatments before they are widely used, while also helping future generations seek treatment. (6)
Dementia Causes and Risk Factors
Dementia occurs when neurons in the brain stop working, lose contact with other brain cells, and die. Researchers are still working to understand why this happens and to investigate the role that genetics, lifestyle and environment all play.
Vascular dementia is linked to damaged arteries that block blood flow to the brain, depriving brain cells of the oxygen and nutrients they need to function. The severity of the obstruction in the brain and its place will determine the effect on thinking and reasoning. Risk factors include atherosclerosis (hardening of the arteries), high cholesterol, high blood pressure and diabetes, among others. Smoking also increases the risk.
Levy For physical dementia, in which abnormal protein leaks in the name of levy bodies interfere with normal brain function, there is an increased risk of other diseases such as Parkinson’s. Scientists believe that the family history of dementia may also be a factor.
So far, scientists have been able to identify a major risk factor for frontemporal disorder (also called frontemporal dementia), which is family history. However, researchers have found molecular and genetic differences between the underlying brain condition, frontotemporal degeneration and amyotrophic lateral sclerosis, also known as Lou Gregg’s disease. Finding these similarities can help scientists better understand and treat both diseases.
