Dementia Symptoms, Causes, Risk Factors & Treatment | Diseases List A-Z

What is Dementia?

Dementia is a term for a group of symptoms that affect memory, thinking skills, and social skills so severely that they interfere with daily life.

Although dementia is generally characterized by memory loss, this condition is different from amnesia.

When someone loses their memory, it does not necessarily mean that they have dementia, although it is often one of the first signs of this condition.

Symptoms of Dementia

Dementia symptoms can develop gradually, starting with mild signs and becoming more serious over time.

The three stages of dementia symptoms include:

Early Symptoms

At this stage, symptoms may be difficult to recognize and are often considered part of the normal aging process. Some early symptoms include:

• Difficulty remembering new information or recent events.
• Often forgets names, places, or everyday objects.
• Difficulty finding the right words when speaking.
• Confused about time, date, or place.
• Loss of interest in activities or hobbies that you normally enjoy.

In addition, mood changes, such as irritability, anxiety, or depression are also early signs of dementia.

Secondary Symptoms

As time goes by, symptoms become more pronounced and begin to interfere with daily activities.

At this stage, people with dementia may experience:

• Difficulty managing finances, such as forgetting to pay bills.
• Confused by familiar surroundings, even lost in familiar places.
• Difficulty following conversations or understanding simple instructions.
• Frequently repeating questions or stories.
• Changes in behavior, such as being suspicious of others or becoming easily angered for no apparent reason.

Intermediate symptoms of dementia are also characterized by the loss of the ability to make decisions or plan things.

Final Symptoms

In the final stages, the sufferer’s ability to live independently is very limited.

Symptoms that appear usually include:

• Inability to recognize family or close friends.
• Difficulty speaking or communicating.
• Loss of control over bodily functions, such as difficulty swallowing or urinating.
• Significant weight loss due to difficulty eating.
• Complete dependence on others for daily activities, such as eating, bathing, and dressing.

It is important to consult a doctor immediately if you or someone close to you shows these symptoms.

Early diagnosis can help better manage symptoms and improve the quality of life for sufferers and their families.

Causes of Dementia

Dementia is caused by damage to the brain’s nerve cells in certain parts, reducing the ability to communicate with other nerves in the body, and causing symptoms to appear according to the area of ​​the brain that is damaged.

There are different conditions in dementia cases. There are types of dementia that develop progressively, and there are also other conditions that resemble dementia that occur due to certain reactions and can be suppressed.

Progressive dementia is a condition caused by damage to certain brain nerve cells and can worsen over time. This condition is generally not completely reversible.

Some types of progressive dementia include Alzheimer’s disease, vascular dementia, Lewy body dementia, frontotemporal dementia, and mixed dementia.

Dementia Risk Factors

Risk factors for dementia that are beyond control or caused by certain disease conditions are:

• Increasing age.
• Family health history (genetics).
• Mild cognitive impairment.
• Sindrom Down.
• Diabetes.
• Obesity.
• High cholesterol.
• Depression.
• Sleep apnea.
• Hypertension.
• Atherosclerosis (fatty buildup on artery walls).

In addition, an unhealthy lifestyle can also increase the risk factors for dementia, including:

• Smoking habit.
• Consuming alcohol.
• Rarely exercise.
• Lack of sleep.
• Unhealthy eating patterns, such as consuming foods high in saturated fat, sugar, and salt.

Types of Dementia

There are many different types of dementia, each with unique characteristics. Here are some of the most common types of dementia:

1. Alzheimer’s dementia

It is the most common form of dementia. It is characterized by impaired memory, orientation, and thinking ability.

The main cause is the accumulation of amyloid and tau proteins in the brain, which interfere with the function of nerve cells.

2. Vascular dementia

Caused by impaired blood flow to the brain, often associated with stroke or high blood pressure.

Common symptoms include impaired concentration, decision-making, and motor problems.

3. Lewy body dementia

Characterized by sleep disturbances, visual hallucinations, and fluctuations in alertness. It is caused by the buildup of proteins called Lewy bodies in the brain.

4. Frontotemporal dementia

This type of dementia affects the front and sides of the brain, causing changes in personality, language, and behavior. It is more common in young people than other types.

5. Mixed dementia

A combination of several types of dementia, such as Alzheimer’s and vascular. Sufferers often experience complex symptoms due to the presence of two different causative mechanisms.

6. Secondary dementia

Caused by other conditions such as head injury, infection, or autoimmune disease. Management depends on treating the underlying condition.

Difference Between Dementia and Alzheimer’s

Dementia is a general term that covers a variety of disorders that cause a decline in brain function, while Alzheimer’s is one of the most common causes of dementia.

Dementia describes symptoms such as memory impairment, difficulty speaking, or behavioral changes caused by a variety of conditions, including Alzheimer’s, vascular dementia, or frontotemporal dementia.

More specifically, Alzheimer’s is a degenerative brain disease caused by the accumulation of abnormal proteins such as amyloid. In dementia, the causes can vary, such as blood vessel problems or head trauma.

In contrast, Alzheimer’s has a characteristic pattern of progression, starting with short-term memory impairment and progressing to a broader loss of thinking skills and brain function.

Understanding these differences is important in determining the appropriate treatment and care approach for the sufferer.

Research on Dementia

Research published by Alzheimer’s Research & Therapy has evaluated the possibility of preventing dementia through lifestyle interventions and risk factor management.

Currently, about one-third of dementia cases are believed to be preventable by changing nine risk factors, such as low education, midlife hearing loss, obesity, hypertension, depression, smoking, physical inactivity, diabetes and social isolation.

These lifestyle changes are believed to have a positive effect decades before dementia symptoms appear.

However, although observational studies have shown promising results, large-scale clinical trials with more rigorous methods have not provided strong evidence.

The National Academy of Medicine concluded in 2017 that there are no specific interventions that can be widely recommended for dementia prevention.

Dementia Diagnosis

Early diagnosis of dementia is essential to ensure timely treatment, manage symptoms, and improve the quality of life for sufferers and their families.

Unfortunately, dementia is not easy to diagnose because many symptoms can indicate similar diseases.

In addition to asking about the patient’s and family’s medical and health history, a physical examination and a series of further tests are also carried out, including:

• Cognitive and neuropsychological tests. Tests such as the Mini-Mental State Examination (MMSE) are used to evaluate cognitive abilities.
• Physical and laboratory examinations. Performed to rule out other causes such as infection, metabolic disorders, or vitamin B12 deficiency.
• Brain imaging. CT or MRI scans of the brain help detect structural changes such as brain atrophy or small strokes. PET scans may also be done to show abnormal patterns of brain activity.

In addition to these steps, regular screening is also highly recommended for people who have risk factors, such as a family history of dementia or mild cognitive impairment.

These routine check-ups allow doctors to detect changes early, even before severe symptoms appear so that treatment can be carried out more effectively.

Screening is also important for older adults who have medical conditions such as diabetes, hypertension, or a history of stroke, as they are more susceptible to dementia.

Complications of Dementia

Dementia is a syndrome of progressive brain function loss that affects various aspects of cognition, including memory, thinking, language, and decision-making abilities. As dementia progresses, complications can arise that significantly affect the sufferer’s physical and mental health, as well as their overall quality of life.

Major Complications of Dementia

Dementia not only causes impaired cognitive function but can also trigger a series of complex complications:

• Loss of Independence and Movement Difficulty: Dementia often causes a gradual loss of independence. People may experience movement difficulties, muscle stiffness, and even tremors, although dementia is different from Parkinson’s disease. These difficulties can make everyday activities like dressing, eating, bathing, and walking more difficult, increasing the risk of falls and injury.
• Malnutrition and Digestive Disorders: People with dementia often have difficulty eating and drinking due to memory problems, difficulty recognizing foods, or problems swallowing. This can lead to malnutrition, weight loss, and deficiencies of essential nutrients. In addition, digestive disorders such as constipation or bowel incontinence are also common due to cognitive and physical decline.
• Infections: People with dementia are more susceptible to infections , especially urinary tract infections (UTIs) and pneumonia. Difficulty moving, incontinence, and a weakened immune system contribute to the increased risk of infection. Infections in people with dementia can be more serious and difficult to treat.
• Sleep Disorders: Sleep disorders such as insomnia, sleep-wake cycle reversal, and restless legs syndrome are common in people with dementia. Sleep disturbances can worsen cognitive symptoms, increase agitation, and decrease overall quality of life.
• Cardiovascular Complications: Although not directly caused by dementia, some studies have shown a link between dementia and an increased risk of cardiovascular problems, including slow heart rate (bradycardia) in some cases. However, this relationship is complex and requires further study.

Impact of Complications on Sufferer’s Health

Complications of dementia have a wide impact on the health of sufferers:

• Physical Health Decline: Complications such as malnutrition, infections, and mobility difficulties significantly decrease the physical health of people with dementia. This can accelerate the overall decline of body function and increase the risk of hospitalization.
• Increased Burden of Care: Complications of dementia increase the burden of care for families and healthcare providers. People with dementia with complications require more intensive supervision and assistance with daily activities, more frequent medical care, and complex management of complications.
• Decreased Quality of Life: The combination of brain decline and physical complications drastically reduces the quality of life for people with dementia. Loss of independence, difficulty communicating, and physical health problems can lead to social isolation, depression, and decreased self-esteem.

Dementia Treatment

Currently, there is no cure for most types of dementia because it is not yet possible to reverse brain cell death. However, treatment can help manage symptoms.

Some medications can help reduce the symptoms of Alzheimer’s disease. For example, donepezil, galantamine, and rivastigmine. Further, can be discussed with the doctor.

In addition to medical treatment, there are also several home treatments that can help manage dementia, namely:

• Implement a healthy diet.
• Regular exercise.
• Regularly check your health.
• Take medication as prescribed.
• Regular sleep.

Dementia Prevention

Dementia cannot be prevented, but there are several things you can do to reduce the risk, such as:

• Quit smoking.
• Exercise regularly.
• Maintain nutritional intake and implement a healthy diet, for example, low-fat and high-fiber foods.
• Reduce alcohol intake.
• Maintain weight.
• Increase your vitamin D intake.
• Exercise your brain regularly, such as reading and playing puzzles.
• Maintaining health, such as controlling blood pressure, blood sugar levels, and cholesterol.
• Avoid head injuries.

In addition, it is very important to maintain heart and blood vessel health to prevent brain blood vessel damage that contributes to dementia.

Maintaining social interactions, such as talking to friends or family, can protect brain function and prevent isolation that contributes to cognitive decline.

Don’t forget to always manage stress through relaxation techniques, meditation, or enjoyable hobbies to prevent the negative effects of chronic stress on the brain.
