Memory loss –Dementia- what is it
What is dementia?
Dementia is a common term for a decrease in mental ability serious enough to hamper with daily life. Loss of memory is an example. The most common types of dementia is Alzheimer's.
Dementia is not the name for a particular disease. It is a general term that relates to a wide range of symptoms associated with a decrease in memory or other thinking skills serious enough to diminish a person's ability to execute everyday activities.
Alzheimer's disease interprets for sixty to eighty percent of cases.
The second most common type of dementia is the vascular dementia, which is caused post a stroke. Symptoms of dementia may be caused because of many other conditions too, inclusive of some that are curable, likes vitamin deficiencies and thyroid problems.
A lot of times dementia is wrongly mentioned as "senile dementia or "senility," which displays the previously widespread but wrong belief that severe mental fall is a normal part of aging.
Memory loss & other signs of dementia:
While the symptoms of dementia can greatly alter, at least 2 of the below basic mental functions must be remarkably weak or damaged to be considered dementia:
Ability to focus and pay attention
Communication and language
Reasoning and judgment
Individuals with dementia may have issues with short term memory, traveling out of the neighborhood, remembering appointments, planning and preparing meals, paying bills or keeping track of a purse or wallet.
A lot of dementias intensify, which means the signs and symptoms begin slowly but they get worse with time. In case you or your beloved ones are having difficulty with their memories or any other changes in their power to reason than do not ignore them. You must visit your physician to rule out the cause. A treatable condition may be diagnosed by the physician examining you or the affected person. It is very important to diagnose the signs of dementia which gives a chance to be treated at the earliest.
When the cells of the brain are impaired it results in dementia. The transmission between the brain cells is hampered when there is damage to the brain cells The behavior, feelings and thinking ability of an individual is affected the communication of the brain cells is not normal.
The brain has many different regions, each of which is responsible for various functions (for example, movement, judgment and memory).That region cannot carry out its functions normally, when cells in a particular region are damaged.
Take our interactive brain tour.
Various Kinds of dementia are linked with particular types of brain cell damage in specific areas of the brain. For example, in Alzheimer's disease, increased levels of specific proteins outside and inside brain cells make it difficult for brain cells to stay fit and to relate with each other. The brain area known as the hippocampus is the hub of memory and learning in the brain, and the brain cells in this part are often the first to be damaged. That is why in Alzheimer's memory loss is one of the foremost signs. That is why memory loss is often one of the earliest symptoms of Alzheimer's.
When the condition is treated or addressed, there may be an improvement in the below state of memory problems and thinking, though many changes in the brain that stimulate dementia are irreparable and get worse with time.
Diagnosis of dementia
Excess use of alcohol
Medication side effects
If someone has dementia there is no one test to determine this.
Alzheimer's and other kinds of dementia are diagnosed by physicians on basis of laboratory tests, a physical examination, a careful medical history and typical changes in every day function, changes in thinking process and behavior related with each kind.
With a high level of certainty, doctors can decide that a person has dementia. But it is difficult to diagnose the accurate type of dementia because the brain changes of various dementias and symptoms can overlap.
In few cases, a physician might diagnose "dementia" and not state a type. If this happens it may be essential to see a specialist such as a gero-psychologist or a neurologist.
Dementia treatment and care
Treatment of dementia relies on its cause.
There is no treatment or cure for most of the developing dementias, that stops it from developing or growing or that slows down the development, inclusive of Alzheimer's disease. But there are drug treatments that may temporarily improve symptoms. But temporary improvement in the symptoms may be seen with some medical treatment. Identical medications used to tackle Alzheimer's are among the drugs occasionally advised to help with symptoms of other kinds of dementias too.
Some symptoms of dementia can be alleviated with non- drug therapies.
Eventually, the path to productive new treatments for dementia is through growing funding in research and increased involvement in clinical studies.
Risk and prevention of dementia:
A few possible factors for dementia, such as genetic and age, can’t be altered.But researchers pursue to explore the effects of other risk factors on brain health and prevention of dementia. Some of the most active regions of research in risk prevention and reduction involve physical fitness, diet and cardiovascular factors.
Cardiovascular risk factors:
Your body's richest networks of blood vessels nourish your brain. Your brain cells are deprived of oxygen and vital food, as any damage to any blood vessels in your body can damage the blood vessels in your brain.
Vascular dementia is linked to the blood vessel alteration in the brain. They frequently exist along with alterations caused by other kinds of dementia, including dementia with Lewy bodies and Alzheimer's disease, and these changes may act together to cause faster deterioration or make disorder more serious. You can help safeguard your brain with some of the same procedures that safeguard your heart - maintain a healthy weight, blood sugar within recommended limits and cholesterol, measures to keep your blood pressure and avoid smoking.
Physical Exercise: The risk of some types of dementia can be lowered with the help of physical exercise Documentation suggests exercise may directly benefit brain cells are benefited with increased blood and flow of oxygen to the brain as a result of exercise as per research evidences.
Diet: What you eat may have its biggest influence on brain health via its effect on heart health. The best present evidence recommends that heart-healthy eating plans, such as the Mediterranean diet, also may help safeguard the brain. A Mediterranean diet involves comparatively little red meat and highlights olive oil whole grains, fish and shellfish, and nuts fruits and vegetables and other healthy fats.
