From time to time, we may forget our keys, a family member's date of birth, or even today's date. But what if the forgetfulness is more than that? What if someone stops while talking and feels lost for words and doesn't remember what they were talking about? Or finds themselves in a place where they don't know why they went or how they should act? In this case, it's not just a passing forgetfulness or lack of focus, but it may be evidence of something bigger. These signs may indicate symptoms of Alzheimer's disease, the incidence of which has seen a significant increase in recent years. So, Dalili Medical provides you with some information about this disease, so keep reading.
**What causes Alzheimer's disease?**
Like all types of dementia, Alzheimer's disease is caused by the death of brain cells. This disease is considered neurodegenerative, which means that there is a gradual deterioration of brain cells over time. The size of the brain generally shrinks due to a decrease in the number of neurons and the connections between them.
**What exactly is Alzheimer's disease?**
Alzheimer's disease is a disorder that affects the brain, gradually destroying memory and thinking skills, eventually impairing the ability to perform simple daily tasks. Symptoms typically appear in most people in their mid-60s, and this type of Alzheimer's disease is known as late-onset Alzheimer's.
**How long can someone with Alzheimer's live?**
In general, a person with Alzheimer's disease lives four to eight years after diagnosis. However, some people may live up to 20 years, depending on several factors. The brain changes associated with the disease begin years before symptoms appear.
. What causes death in people with Alzheimer's?
The main cause of death for people with Alzheimer's is often secondary infections, the most common being pneumonia. In healthy individuals, bacterial infections can usually be treated with antibiotics, but they can pose greater risks for those with Alzheimer's disease due to weakened immune systems.
. What are the early signs and symptoms of Alzheimer's disease?
Alzheimer's disease can have early warning signs and symptoms, such as forgetting recent conversations or events, having difficulty solving problems, being disoriented in time or place, experiencing mood or behavior changes, or having difficulty performing routine tasks.
. What causes death in Alzheimer's patients?
The main cause of death in Alzheimer's patients is often secondary infections, most notably pneumonia. In healthy individuals, bacterial infections can usually be treated with antibiotics, but these infections are a greater risk for people with Alzheimer's disease because their immune systems are weakened.
. What are the early signs and symptoms of Alzheimer's disease?
Alzheimer's patients can have early signs and symptoms, such as forgetting recent conversations or events, having difficulty solving problems, being disoriented in time or place, having mood or behavior changes, or having difficulty performing daily tasks.
. Does Alzheimer's disease have genetic roots?
Genetics play a role in the risk of developing Alzheimer's disease. People with a family history of the condition are more likely to develop it, but genetics are not the only factor. Environmental and lifestyle factors also contribute.
Why do Alzheimer's patients scream?
Screaming from Alzheimer's patients can be caused by several reasons, such as feeling lost or afraid. These patients may lose the ability to express their needs clearly, which leads them to protest loudly for help or to express their confusion. In addition, screaming may be a reaction to stress or frustration, as the patient feels unable to understand or deal with situations easily, which causes them to express their feelings loudly.
**The most difficult stages of Alzheimer's**
The advanced stage of Alzheimer's disease is one of the most difficult stages that the patient goes through, as there is a significant deterioration in brain function, and memory loss and the ability to think and express increases. At this stage, patients have difficulty recognizing familiar people, and may completely forget family places and daily skills such as eating, drinking, and interacting with their surroundings. This deterioration can lead to feelings of frustration and isolation, especially when the patient realizes that he is gradually losing his identity and self. Relatives and loved ones also suffer from great psychological stress as a result of the deterioration of the health of their loved ones and the loss of memories and abilities they once had. At this stage, it becomes necessary to know how to deal with an Alzheimer's patient, as it requires special and continuous care. Patients are often transferred to specialized care centers to ensure that they receive the necessary care that meets their increasing needs.
Reasons for the inability to walk in Alzheimer's patients?
Alzheimer's disease affects the ability to walk in several ways, the most prominent of which are:
1. **Deterioration of motor ability**: Alzheimer's leads to the deterioration of brain functions responsible for controlling movement and coordination, causing weakness in the ability to walk and move normally.
2. **Muscle weakness and balance**: Many Alzheimer's patients suffer from muscle weakness and loss of balance, which increases the risk of falling and reduces their ability to walk steadily.
3. **Emotional and psychological impact**: Alzheimer's can affect the patient's psychological and emotional state, leading to a decreased desire to engage in physical activities, including walking.
4. **Memory and coordination impairment**: Deterioration in memory and the ability to coordinate movements affects the ability to walk normally, increasing the likelihood of falling and reducing confidence in performing motor activities.
5. **Side effects of medications: Alzheimer's patients may take a range of medications that canIt can lead to dizziness or general weakness, which negatively affects their ability to move.
What are the factors that contribute to the development of Alzheimer's disease?
- Aging, as the likelihood of developing the disease increases after reaching the age of 65.
- Having a family history of the disease.
- Some genetic factors, as Alzheimer's disease can be caused by a genetic defect in rare cases, but these cases represent less than 1% of all patients.
- Severe or repeated brain injuries.
- Exposure to environmental pollutants, such as toxic metals, pesticides, and industrial chemicals.
- Smoking.
- Obesity.
- Diabetes.
- Untreated depression.
- Down syndrome.
- Cardiovascular diseases, including high blood pressure and high cholesterol levels.
- Stroke.
- Immune system problems.
What are the signs of Alzheimer's disease?
The signs of Alzheimer's disease vary depending on the stage of the disease, and they usually develop slowly over several years. Sometimes, they can be confused with signs of other age-related conditions. The speed at which symptoms progress varies from person to person, and it is not possible to accurately predict how quickly the condition will worsen.
In general, the signs of Alzheimer's disease are divided into three main stages.
**Signs of Alzheimer's in the early stages**
In the early stages, the signs of Alzheimer's disease are often mild, and the most prominent one is usually frequent forgetfulness. A person may experience:
- Forgetting recent events or conversations.
- Misplacing things (such as putting keys in the refrigerator).
- Forgetting appointments.
- Forgetting the names of people, objects, or places.
- Difficulty finding the right words when speaking.
Other early signs may include:
Mood changes include increased anxiety or irritability, as well as feeling unsettled by any change in daily routine. Repetitive behaviors, such as asking the same question multiple times, wanting to isolate yourself, and difficulty making decisions, may also occur.
As for the symptoms of Alzheimer's disease in its middle stage, memory problems will get worse. The affected person may have increasing difficulty remembering the names of people they know, and may have difficulty recognizing family members and friends.
Other symptoms include:
- Confusion, such as getting lost in familiar places.
- Delusions.
**Hallucinations**: seeing or hearing things that are not really there.
**Obsessive behaviors**: repeating certain behaviors compulsively.
**Speech difficulties**: problems expressing speech.
**Sleep disorders**: problems related to sleep.
**Disorientation in places**: inability to determine directions and distances, which may lead the person to get lost or feel disoriented.
**Inability to distinguish time**: difficulty understanding or determining the time.
**Late-stage symptoms of Alzheimer's disease**:
In the advanced stages of Alzheimer's disease, symptoms become more severe and become more painful for the affected person, in addition to their impact on caregivers, friends, and family.
Advanced symptoms of the disease include:
Aggressive behaviour.
Incontinence of urine or stool.
Difficulty eating and swallowing.
Difficulty changing positions, sleeping or moving without help.
Difficulty speaking and choosing words.
Significant problems with short-term and long-term memory.
Weight loss (some people may eat a lot and gain weight).
Weakness.
At this stage, people with Alzheimer's disease usually need support to help them get on with their daily lives. For example, they may need help with eating, bathing, dressing and using the toilet. In later stages, they may become anxious or aggressive, or wander away from home. Eventually, they will need full-time care, which can be a huge stress for the family members who have to look after them.
**The Seven Stages of Alzheimer's**
Alzheimer's disease develops gradually, becoming more severe over time. The disease has seven main stages, as follows:
**Stage 1: No Deterioration**At this stage, Alzheimer's disease cannot be detected. There are no memory problems or signs of dementia.
**Stage 2: Very Mild Deterioration**Some minor memory problems may appear, such as occasionally misplacing things or forgetting small details. However, performance on memory tests remains generally good, making it difficult to distinguish the symptoms from normal age-related changes.
**Stage 3: Mild Deterioration**At this stage, friends and family members of the elderly may begin to notice problems with memory and cognition. Performance on memory and cognitive tests is affected, and doctors will be able to identify a decline in cognitive function. Patients at this stage may experience difficulties in several areas, including:
- Difficulty choosing the right words during conversations.
Forgetting the names of new people.
Challenges in planning and organizing.
Sometimes losing personal belongings, including valuables. Doctors can now detect cognitive impairment by conducting tests.
Stage 4: Moderate Decline Patients with Stage 4 Alzheimer's disease:
The symptoms of Alzheimer's disease are clearly visible.
They have difficulty doing basic math.
They forget recent events or details from their personal history.
They have poor short-term memory, such as forgetting what they ate for breakfast.
They have challenges managing finances and paying bills.
**Stage 5: Moderate Decline**Individuals at this stage of the disease may face a range of challenges, requiring assistance with many daily activities. The most prominent symptoms they show are:
- Noticeable confusion, especially regarding time and place.
- Difficulty rememberingr Basic personal information, such as phone number.
- Inability to dress properly without assistance.
Despite these difficulties, many people are able to perform some basic self-care tasks, such as bathing and using the toilet, and retain some memories related to family and youth.
**Stage 6: Severe Decline** At this stage, patients with Alzheimer's disease need constant supervision and often require specialized care. Symptoms include:
- Severe confusion or lack of awareness of the surrounding environment.
- Marked personality changes and possible behavioral problems.
- Dependence on others for activities such as using the toilet and bathing.
- Difficulty recognizing faces, except for close relatives and friends.
- Loss of control of the bowels and bladder, in addition to the tendency to wander.
Stage 7: Very severe deterioration This stage is the last in the course of Alzheimer's disease. Since this disease is a chronic disease, patients at this stage are close to death. They show:
- Severe impairment in the ability to interact with the environment or communicate effectively.
- Saying words or phrases without understanding their meanings.
- Complete dependence on others for all daily activities, including eating and using the bathroom.
- Difficulty swallowing can lead to complications such as pneumonia.
**How to diagnose Alzheimer's disease**
Doctors rely on a range of methods to determine whether a person with memory problems has Alzheimer's disease, as there are many other conditions, especially some neurological disorders, that can lead to dementia and similar symptoms.
In the early stages of diagnosing Alzheimer's disease, the doctor asks the patient and his family members a series of questions to better understand his health condition and lifestyle. The initial diagnosis includes questions related to:
- The patient's general health.
- The medications he is currently taking.
- His detailed medical history.
- His ability to perform daily activities.
- Any changes in mood, behavior, and personality.
Then, the doctor does the following:
- Perform a physical and neurological examination.
- Conducting a mental status assessment test, which includes tests to assess memory, problem solving, attention, basic math, and language.
- Conducting medical tests such as blood and urine tests to rule out other possible causes of symptoms.
Imaging tests, such as CT scans, MRI scans, and PET scans, are used to confirm a diagnosis of Alzheimer's disease or to rule out other possible conditions.
**Can Alzheimer's disease be prevented?**
There is no sure way to prevent Alzheimer's disease, but a healthy lifestyle can help promote brain health and overall health. Research has not yet been able to identify an effective way to prevent Alzheimer's disease, but studies are still ongoing.
In general, the following tips can help reduce your risk of developing Alzheimer's disease:
- Eating a balanced diet rich in vitamins, minerals, and beneficial fatty acids, especially omega-3.
- Quitting smoking and avoiding alcohol.
- Maintain a good level of physical activity, at least 30 minutes five times a week.
Regularly practicing activities or games that require mental skills, such as Sudoku, chess, puzzles, and crosswords, contribute to stimulating the mind and promoting the growth of brain cells and strengthening the connections between them.
It is important to maintain a healthy lifestyle and a diet that is beneficial to cardiovascular health.
Weight should be lost in a healthy way if there is obesity.
Regular periodic checkups should be performed as you age.
**What is the best treatment for Alzheimer's disease?**
There is currently no treatment that can stop Alzheimer's disease, although there are many medications approved by the US Food and Drug Administration (FDA) that help control some symptoms and prevent them from worsening, but only for a limited period. Most medications work best for people in the early or middle stages of the disease. Researchers are currently studying other drug treatments that aim to delay or prevent the disease, in addition to treating its symptoms.
In addition to medications, the doctor will develop a nutritional and lifestyle plan for the patient and those around him, to guide them on how to deal with the condition properly.
The most prominent medications used in the treatment of Alzheimer's disease**
Starting treatment as soon as possible for Alzheimer's disease can help maintain daily functioning for a period of time, however, the medications currently available will not stop or reverse Alzheimer's disease.
There is no general medicine for all Alzheimer's patients, because the disease affects each patient differently, and the doctor will determine the best medications based on the patient's condition and the stage of disease progression.
Two types of medications have been approved to treat the symptoms of Alzheimer's disease, namely:
Cholinesterase inhibitors
The doctor prescribes this class of medications to control the symptoms of mild to moderate Alzheimer's disease.
This class includes the following medications:
Donepezil, approved by the Food and Drug Administration (FDA) to treat moderate to severe Alzheimer's disease.
Rivastigmine.
Galantamine.
NMDA antagonists
Such as memantine, which is an approved medication to treat the symptoms of moderate to severe Alzheimer's disease. Research has shown that people with Alzheimer’s disease who take memantine are better able to perform activities of daily living such as eating, bathing, dressing, and other basic skills.
The U.S. Food and Drug Administration (FDA) has granted accelerated approval to aducanumab (Aduhelm™), the first disease-modifying treatment for Alzheimer’s disease. The drug helps reduce amyloid deposits in the brain.
Aducanumab is a new drug, and researchers have only studied its effects in people with early Alzheimer’s disease, so it may only help people in the early stage.
Your doctor may prescribeThere are also other medications to control symptoms of Alzheimer's, including:
**Antidepressants**
**Anti-anxiety medications**
**Anti-seizure medications**
**Antipsychotics**
**Home safety tips for Alzheimer's patients**
If you are caring for someone with Alzheimer's, it is essential that the home is a safe environment, as these people are at high risk of injury.
You can take some steps to make the home safer, such as:
- Make sure there is at least one handrail if there are stairs.
- Put colored marks on the edges of the steps to increase their visibility.
- Cover unused electrical outlets, and consider installing safety latches on closet doors and house doors.
- Remove unused items, and get rid of small rugs, electrical cords, and other things that may cause tripping.
- Make sure all rooms and outdoor areas where the person is present are well-lit.
- Use a sturdy shower chair to support the unstable person and prevent falls.
- Remove curtains and rugs with busy patterns that may cause confusion.
- Secure or lock cleaning products and household items, such as paint thinner and matches.
- Install surveillance cameras in the home if you are away from home.
- Hang a paper containing the patient's identity and address.
