Dementia is a health condition affecting more than 55 million people worldwide in 2022, and the numbers may drastically increase in the next 30 years. While it might not seem obvious until you start getting older, a decline in memory and mental abilities is severe enough to interfere with daily life and does so quite easily imagining not only forgetting where you put your car keys but forgetting that you can drive at all, for example. As for what causes dementia, there can be several different diseases or health conditions that lead to a mental decline.
In this blog, we will look at what dementia is, what its causes, symptoms, and treatment options are.
Dementia is a common term used to describe a wide range of symptoms related to a decline in memory and intellectual functions. Dementia causes damage to the brain nerve cells resulting in a decline in memory and other cognitive functions. There are many types of dementia, and all of them affect the brain.
The common symptoms of dementia include progressive memory loss, declining decision-making ability, inability to learn new things, and behavioral changes. There are treatment options for dementia, but most of these treatments can only manage the symptoms and slow down the disease from progressing.
There are many different causes of dementia, but some are more common than others. Here are the top 5 causes of dementia:
The most common cause of dementia is Alzheimer’s disease. Alzheimer’s disease is a degenerative brain condition that leads to cognitive decline and memory loss. Patients with Alzheimer's have clumps of protein beta-amyloid (plaques) and fibrous tangles of tau protein in their brains. These plaques and tangles damage the healthy neurons of the brain and cause dementia.
Vascular dementia is caused by problems with the blood vessels in the brain, which can lead to strokes or mini strokes. These can damage brain tissue and cause cognitive problems. Some of the most common symptoms of vascular dementia include slowed thinking, lack of focus, and difficulty in being organized. Vascular dementia can also damage the brain in other ways like damaging fibers in the white matter of the brain.
This form of dementia is caused by the build-up of Lewy bodies in the brain, which are abnormal balloon-like clumps of proteins. LBD is a more common form of progressive dementia. Along with several cognitive issues, LBD can cause problems with movement. Furthermore, it can also cause visual hallucinations, tremors, and uncoordinated movements in some patients.
This type of dementia is caused by damage to the frontal and temporal lobes of the brain, which can lead to changes in behavior and personality. The damage in the nerve cells of the frontal and temporal lobes of the brain can further affect the language, movement, and judgment of the patient.
Generally, people over the age of 80 have dementia that is caused by a combination of many different forms of dementia. Someone, for example, could have LBD while also having vascular dementia, making the type of dementia mixed in nature.
If you or a loved one is experiencing any of the symptoms of dementia, it’s important to see a doctor for a diagnosis. There is no one-size-fits-all treatment for dementia, but early diagnosis and treatment can vastly improve quality of life.
The symptoms of dementia include both cognitive and psychological changes in the one who has it. Here are some of the most common symptoms of dementia:
Other psychological changes associated with dementia include:
The process of diagnosing dementia can be pretty long and complicated as there are no specific tests or imaging studies that can definitively diagnose dementia. It requires evaluation by a team of neurologists, psychiatrists, and other specialists. The diagnosis of dementia, therefore, is based on an evaluation of the person's ability to perform activities of daily living, such as bathing, dressing, eating, and going to the bathroom. Other tests measure things like walking, balance, coordination, vision, and hearing. Testing will also include a thorough look at the patient's medical history, general appearance and behavior, and family history.
Frequently, the physician will speak with the family member who is the main caregiver, who will be questioned about the patient's behavior. In addition, the physician will ask a series of specific questions about the patient's memory, language, and behavioral changes. These tests can be given in a doctor's office or a hospital, or they might require the patient to go to a special testing center.
There is no one-size-fits-all answer to this question, as the best treatment approach for dementia will vary depending on the individual and the type of dementia they are living with. However, a few general treatment options are often used to help manage the condition:
Whatever approach is taken, it is essential to remember that dementia is a progressive condition with no cure. However, with the right treatment approach, many people with dementia can live well for many years.
Dementia is one of the most common degenerative diseases worldwide. While its cause is still unknown, several risk factors have been linked to the development of dementia. The top 6 risk factors associated with dementia are as follows:
Dementia is a progressive brain disorder, meaning that the sooner it is detected, the sooner it can be managed, giving the person with dementia that much more quality of life. If you are concerned that you or a loved one might have dementia, having a specialist perform the necessary tests to diagnose you is never a bad idea.
