Description for dementia

A group of symptoms affecting memory, thinking, and social abilities severely enough to interfere with daily functioning, often caused by diseases like Alzheimer's.

General Information on dementia

Cause: Symptoms of dementia include a progressive loss of cognitive and functional ability, leading to a loss of independence. There are currently no effective treatments, but many trials are underway that may offer hope to patients and their families.

Cure: Management of symptoms, medications to slow progression (if applicable), therapy, support services.

Symptoms:

Symptoms of dementia

confusion, difficulty with communicatio, difficulty with problem-solvi, memory loss, mood changes

Precautions for dementia

Engage in cognitive exercises, Maintain a structured routine, Provide a safe environment, Monitor nutritional intake

Question: what is dementia?

Dementia is a neurodegenerative disease that has several different forms, symptoms, and causes. There's currently no cure, but researchers are looking into effective treatments and ways to prevent it.
Dementia is a decline in cognitive function. To be considered dementia, mental impairment must affect at least two brain functions. Dementia may affect:
Dementia may be caused by a variety of illnesses or injuries. Mental impairment may range from mild to severe. It may also cause personality changes.
Some types of dementia are progressive. This means they get worse over time. Some types are treatable or even reversible. Some experts restrict the term 'dementia' to irreversible mental deterioration.

Question: What are the usual symptoms of dementia?

In its early stages, dementia can cause symptoms, such as:
Not coping well with change. Someone may have a hard time accepting changes in schedules or environment.
Subtle changes in short-term memory making. Someone can remember the events of 15 years ago like it was yesterday, but they can't remember what they had for lunch.
Reaching for the right words. Word recollection or association may be more difficult.
Being repetitive. Someone may ask the same question, complete the same task, or tell the same story multiple times.
Confused sense of direction. Places someone once knew well may now feel foreign. They may also struggle with driving routes they've taken for years because it no longer looks familiar.
Struggling to follow storylines. Someone may find following a person's story or description difficult.
Changes in mood. Depression, frustration, and anger are not uncommon for people with dementia.
Loss of interest. Apathy may occur in people with dementia. This includes losing interest in hobbies or activities that they once enjoyed.
Confusion. People, places, and events may no longer feel familiar. Someone might not remember people who know them.
Difficulty completing everyday tasks. A person in the early stages of dementia may have trouble recalling how to do tasks they've done for many years.

Question: causes of dementia?

Dementia has many causes. In general, it results from the degeneration of neurons (brain cells) or disturbances in other body systems that affect how neurons function.
Several conditions can cause dementia, including diseases of the brain. The most common causes are Alzheimer's disease and vascular dementia.
Some of the more common causes of dementia include:
Neurodegenerative diseases
'Neurodegenerative' means that neurons gradually stop functioning or function inappropriately and eventually die.
This affects the neuron-to-neuron connections, called synapses, which arehow messages are passed along in your brain. This disconnect can result in a range of dysfunction.
Alzheimer's disease
Parkinson's disease with dementia
vascular dementia
chronic alcohol use disorder
Another cause is frontotemporal lobar degeneration. This is a blanket term for a range of conditions that cause damage to the frontal and temporal lobes of the brain. They include:
frontotemporal dementia
Pick's disease
supranuclear palsy
corticobasal degeneration
Other causes of dementia
Dementia has other causes, including:
structural brain disorders, such as normal pressure hydrocephalus and subdural hematoma
metabolic disorders, such as hypothyroidism, vitamin B12 deficiency, and kidney and liver disorders
toxins, such as lead
certain tumors or infections of the brain
medication side effects
Some of these types of dementia may be reversible. These treatable causes of dementia may reverse symptoms if they're caught early enough. This is one of the many reasons why it's important to contact your doctor and get a medical workup as soon as symptoms develop.

Question: How do doctors usually treat dementia?

Two primary treatments are used to alleviate symptoms of dementia: medications and non-drug therapies. Not all medications are approved for each type of dementia, and no treatment is a cure.
Medications for dementia
Two main types of medication are used to treat symptoms of Alzheimer's disease and other dementia-causing conditions:
Cholinesterase inhibitors. These drugs increase a chemical called acetylcholine. This chemical may help form memories and improve judgment. It may also delay worsening symptoms of Alzheimer's disease.
Memantine. This drug is used to delay the onset of cognitive and behavioral symptoms in people with moderate or severe Alzheimer's disease. Memantine may let people with Alzheimer's disease maintain their usual mental functions for a longer period of time.
These two drugs may also be prescribed together. Side effects can occur. Other medications may be prescribed to treat related symptoms, such as impaired sleep, mood changes, and more.
Aducanumab (Aduhelm)
Aducanumab is another medication approved to treat Alzheimer's and may slow the progression of the disease, though research is ongoing. Aducanumab is an anti-amyloid antibody therapy delivered intravenously. It targets a specific protein fragment that can disrupt communication between nerve cells in the brain.
Non-drug therapies
These therapies may help reduce symptoms of dementia and alleviate some of the manageable complications of the condition. Common non-drug treatments for dementia include:
Modifying your environment. Clutter, noise, and overstimulation may reduce focus.
Modifying common tasks. You can work with a therapist or other healthcare professional to break down everyday activities, such as showering or grooming, into manageable tasks.
Occupational therapy. Occupational therapists are specialized healthcare professionals who can help you learn to be safer and more secure with tasks including walking, cooking, and driving.

Question: What are the ways to prevent dementia?

For decades, doctors and researchers believed dementia could not be prevented or cured. However, new research suggests that may not be the case.
A 2017 review found that more than one-third of dementia cases may be the result of lifestyle factors. Specifically, the researchers identified nine risk factors that may increase a person's chance of developing dementia. They include:
midlife hypertension
midlife obesity
hearing loss
late-life depression
diabetes
physical inactivity
smoking
social isolation
lower levels of education
The researchers believe that targeting these risk factors with treatment or intervention could delay or possibly prevent some cases of dementia.
A 2019 retrospective study
looked at nearly 200,000 participants of European ancestry. The study suggested that lifestyle factors such as smoking status, physical activity, diet, and alcohol consumption could potentially contribute to the risk of dementia.
These findings suggest that working with your doctor to maintain a healthy and active lifestyle could help prevent or delay the onset of dementia.
