New Alzheimer’s disease Causes,symptoms,Treatment and Prevention #1

what causes Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease. It is the most common form of dementia. Alzheimer’s disease accounts for 60% to 80% of dementia cases.

Alzheimer disease is a progressive brain disorder that gradually destroys memory and cognition. It has recently been discovered that Alzheimeralzheimer’s disease causes an increase in the production of the amyloid-b protein, which clumps together and forms plaques in the brain. These plaques are associated with areas of damage to the neurons of the brain, which result in the characteristic symptoms of Alzheimeralzheimer’s disease.

 Alzheimer's disease

Alzheimeralzheimer’s disease usually begins after age 60. symptoms include memory loss, disorientation, and personality changes. As symptoms progress, patients develop severe memory impairment and confusion, become depressed or anxious, lose their ability to reason, recognize people and places or communicate effectively, and eventually become unable to care for themselves.

Changes in the brain cause the symptoms of Alzheimer’s disease. Mild impairment may be present for years before the diagnosis is made; however, the duration of the clinical stage of the illness typically ranges from 3 to 20 years. Alzheimer’s disease is ultimately fatal.

In most people with Alzheimer’s disease, symptoms first appear after age 60. However, early-onset forms of the disorder can arise when people are in their 30s, 40s, or 50s.

Alzheimer’s disease signs and symptoms

Alzheimer’s disease is a progressive disease that destroys memory and other critical mental functions. The most frequent form of dementia is Alzheimer’s disease, defined as a progressive loss of intellectual, behavioral, and social abilities that impair a person’s ability to operate independently.

Alzheimer’s signs and symptoms can be mild, moderate, or severe. They include:

Memory loss that disrupts daily life

Challenges in planning or solving problems

Having Difficulty completing familiar tasks at home, at work, or leisure

How Is Alzheimer’s Diagnosed?

The diagnosis of Alzheimer’s disease is based on the symptoms present in the patient. There are no specific tests for diagnosing Alzheimer’s disease. The following are some of the signs that can be used to diagnose Alzheimer’s:

– Memory loss, confusion, and trouble thinking clearly

– Problems with language, reading, writing, or understanding visual images

– Misplacing items and being unable to retrace your steps

– Changes in mood or behavior

– Problems with judgment

– Trouble completing familiar tasks at home, at work, or leisure

Alzheimer’s disease stages

The seven stages of Alzheimer’s help understand the progression of the disease. While everyone’s experience is different, this timeline can help families recognize and understand the changes over time.

Stage 1: no impairment

Stage 2: Very mild decline

Stage 3: mild decline

Stage 4: moderate decline

Stage 5: moderate, mid-stage

Stage 6: moderately severe

Stage 7: severe, late-stage

The condition usually begins in people over age 65. Alzheimer’s disease is sporadic in people younger than 40.

Alzheimer’s is a progressive disease, which means it gets worse over time and worsens as it moves through its stages. 

Alzheimer’s disease life expectancy

Per person, people with Alzheimer’s disease life expectancy (A.D.) have medical expenditures that are approximately three times higher than those without A.D. For older adults with A.D., the average cost of care is estimated to be about $56,800 per year for community residents and about $70,900 per year for nursing home residents. The total cost of dementia care is expected to rise dramatically in the coming years as baby boomers reach their 60s. By 2050, 50 million individuals worldwide will have A.D. and related disorders. By 2050, the total direct costs of dementia care in the U.S. alone will be over $1 trillion annually.

The prognosis for patients with dementia depends on many factors, including the underlying cause of dementia. People with Alzheimer’s disease usually survive 3 to 9 years after diagnosis. However, survival ranges from fewer than one year to 20 or more years in some patients.

In the United States, Alzheimer’s disease is the sixth most significant cause of death.

Alzheimer’s disease strikes someone in the United States every 65 seconds. By the middle of the century, someone in the United States will get the disease every 33 seconds.

Alzheimer’s dementia will affect 5.8 million Americans of all ages by 2023. This number includes an estimated 5.6 million people age 65 and older and approximately 200,000 individuals under age 65 who have younger-onset Alzheimer’s. One in 10 people age 65 and older (10%) has Alzheimer’s dementia.

Since 1906, when a German physician called Dr. Alois Alzheimer noticed abnormalities in the brain tissue of a lady who had died of an uncommon mental disorder, the disease has been recognized. He discovered aberrant aggregates (now known as amyloid plaques) and twisted fiber bundles (now called neurofibrillary tangles). One of Alzheimer’s disease’s most noticeable symptoms is plaques and tangles in the brain.

Alzheimer’s disease genetic

Alzheimer’s disease has yet to be understood entirely. It is believed that most cases result from lifestyle and genetic factors. This may be discovered by looking at a person who has been diagnosed with Alzheimer’s disease’s family history. If the disease is present in other family members, it may be caused by genetic factors. However, if there are no family members with the condition, lifestyle factors such as smoking and alcohol intake may have played a part.

The gene that carries the most risk for Alzheimer’s disease is APOE e4. It has long been known that people with a specific version of this gene have a higher risk of developing Alzheimer’s. Recent studies reveal that the APOE e4 version makes Alzheimer’s more likely and causes the disease to progress faster.

One of the mysteries about this gene is that it also protects against other diseases, such as heart disease. It is not yet clear how APOE e4 does this, but researchers are trying to learn more about this phenomenon.

The other part of the new research focused on studying the early stages of Alzheimer’s in people who did not have symptoms of dementia but who were at high risk because they had a parent with the disease. Many people who live into their 80s and 90s develop some changes in their brains that are characteristic of Alzheimer’s disease, including deposits of a protein called beta-amyloid. But these changes do not cause symptoms unless they reach a critical stage.

Types of Alzheimer’s disease

there are three different types of Alzheimer’s disease:

  1. familiar
  2. sporadic
  3. Late-onset.

These types have a different source of origin, and some can be inherited from family members.

The most common type of Alzheimer’s disease, late-onset Alzheimer’s (LOAD), usually begins after age 65, and the risk goes up as people advance in age. Researchers have discovered several gene mutations associated with late-onset Alzheimer’s. People who inherit these gene changes almost always develop the disease. The genes that increase the risk of late-onset Alzheimer’s make proteins involved in nerve cell function. Researchers believe that the altered proteins somehow lead to a steady buildup of beta-amyloid plaques and tau tangles in the brain. However, most people with late-onset Alzheimer’s do not have a family history.

Familial Alzheimer’s Disease

Familial Alzheimer’s disease (FAD) is an early-onset form of Alzheimer’s passed down from parent to child. It accounts for less than 1 percent of all Alzheimer’s cases. Mutations cause FAD in one of three genes: presenilin 1, presenilin 2, or amyloid precursor protein (APP). All three genes play essential roles in making the beta-amyloid protein. People with FAD tend to develop symptoms between their 30s and mid-50s.

is Alzheimer’s a prion disease

I still think Alzheimer’s is a prion disease.

It is not caused by amyloid – amyloid is a symptom of the disease, not the cause. It is what happens to the brain when it doesn’t have enough copper, and it is also one of the mechanisms that kill neurons.

The cause of Alzheimer’s is prions. Prions are a natural part of your body, and they are primarily in your intestines. They are proteins that fold in different ways and can cause other proteins to fold in the same way. The prions that cause Alzheimer’s are called PIP2 prions. They don’t cause any problems, but if you get too much iron in your system, they can change their shape and bind to more prions and make them change their body and eventually cause massive p2p replication across your neurons.

This causes a massive increase in oxidative stress and free radical damage. Your mitochondria now have access to heme from hemoglobin with no copper to turn into a ceruloplasmin antioxidant enzyme. You also end up with low levels of acetylcholine because you have no copper left to recycle it after each firing.

Alzheimer’s disease icd 10

Alzheimer’s disease ICD-10 code. Alzheimer’s disease is classified to ICD-10 code G30.9, without specifying laterality or severity. As the patient’s condition progresses, they may acquire dementia-like symptoms and finally lose the capacity to communicate.

Alzheimer’s disease is an irreversible, degenerative brain illness that gradually erodes memory and cognitive abilities and the ability to do even the most basic activities. Symptoms of Alzheimer’s disease usually show in persons in their mid-60s. Although current Alzheimer’s therapies can’t stop the disease from developing, they can help people with Alzheimer’s, and their carers live better lives by temporarily slowing the progression of dementia symptoms and improving their quality of life.

Early signs of Alzheimer’s include difficulty remembering recent conversations or events. People may not recognize family members or have trouble speaking or writing as the disease progresses. Eventually, they may become anxious or aggressive or wander away from home. After diagnosis, the average life expectancy is three to 11 years, though some patients live 20 years or more.

A diagnosis of Alzheimer’s disease cannot be confirmed by blood tests or brain imaging. Doctors diagnose Alzheimer’s using information about medical history and changes in thinking and behavior observed during a neurological exam and detailed cognitive testing.

Alzheimer’s disease treatment

Alzheimer’s disease is a gradual, degenerative brain illness in which aberrant proteins build up and cause nerve cells to die. The transmitters that convey signals are disrupted, and the brain shrinks.

There are two main types of Alzheimer’s disease: early-onset and late-onset. Early-onset Alzheimer’s is an inherited form of the disease that affects people under 65. In the United States, it accounts for less than ten percent of all cases. The most frequent type of illness is late-onset, which affects persons over 65.

Scientists have made considerable advances in understanding Alzheimer’s disease; people could be forgiven for thinking that Alzheimer’s was a relatively rare disease. 

scientists are looking at a variety of therapy options, including:

  -using antibodies to clear amyloid-b from the brain

 -using drugs to reduce its production

  -developing drugs that slow down the formation of amyloid-b aggregates

The U.S. medical system has been slow to respond to this epidemic, partly because we were slow to acknowledge it. A 2012 report from the National Alzheimer’s Project Act identified “a sense of denial, among not only patients and caregivers but also health care professionals, researchers, government officials and others” as a significant cause of our collective failure to address this crisis.

Today, researchers are taking a much more aggressive approach toward developing interventions that can prevent or reverse cognitive decline in older adults who have not yet been diagnosed with dementia. We are also learning more about treating and curing Alzheimer’s disease and having several promising new drugs tested on patients with early-stage and advanced disease. A neurodegenerative disorder that causes dementia kills about half a million Americans each year.

Alzheimer’s disease caused by deficiency of Neurotransmitter

A lack of vitamin B-1 causes Alzheimer’s disease.

We know that a deficiency of a particular neurotransmitter causes Alzheimer’s disease. It seems likely that a lack of some nutrients causes this deficiency. What is it?

This is the kind of problem you need to be able to solve if you want to cure Alzheimer’s. But we don’t yet have the techniques for solving it. When they think about biomedical research, most people imagine someone doing an experiment in which one group of mice gets injections of substance X. Another group receives placebo injections and then measures how long they live how happy they are. And when a scientist experiments that, he is usually trying to answer a question like “Is substance X good for you?” or “Does substance X cause cancer?”

But what we need is not just better experiments but better questions. We need investigations that answer questions like “What causes Alzheimer’s?”

Alzheimer’s disease pathophysiology

Alzheimer’s disease (A.D.) is a progressive neurodegenerative disease that occurs in the elderly, and it is the most common form of dementia. It is characterized by pathologic changes in the brain, including neuronal loss and atrophy, cerebral cortical degeneration, senile plaques, neurofibrillary tangles, and neuronal injury. It can produce cognitive impairment in patients with memory loss, personality changes, and language dysfunction. The pathology of A.D. has been divided into pre-clinical and clinical stages. This essay will introduce the characteristic symptoms of A.D. during the pre-clinical phase, discuss the pathophysiology of A.D. during this stage, and analyze the pathological process of A.D.

Although these lesions’ pathogenesis remains fully clarified, the underlying cause of Alzheimer’s disease is considered to be amyloid-β (Aβ) protein deposition. Aβ is a 40-42 amino acid peptide produced by proteolytic processing of the amyloid precursor protein (APP). APP is expressed in many tissues, especially in the brain. APP has been localized to neurons and astrocytes but not to microglia or endothelial cells. APP is also present in platelets and the plasma.

Aβ can be produced through several isoforms: Aβ40 (the predominant isoform) and Aβ42 are the most common forms found in vivo; less common are Aβ38, Aβ43, and Aβ44. These isoforms differ by one or two amino acids at their C termini.

Aβ causes Alzheimer’s disease primarily by aggregating oligomers, fibrils, and senile plaques that form extracellular within the brain.

Alzheimer’s disease vs. dementia

Alzheimer’s disease is the most frequent form of dementia, defined as a loss of cognitive and social ability that interferes with daily activities.

These two terms are often used interchangeably, but they aren’t the same. Alzheimer’s disease is specific. Dementia is not a particular disease. The second most frequent type of dementia is vascular dementia, which develops after a stroke. But many other conditions can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.

Dementia is sometimes mislabeled as “senility” or “senile dementia,” reflecting the erroneous idea that significant mental deterioration is a natural aspect of aging.

Alzheimer’s disease is a neurological illness that causes a mental function to deteriorate over time. It is the most common form of dementia and affects millions of people worldwide. But what exactly is dementia?

Dementia is not a specific disease. It’s a broad phrase that refers to the symptoms of deterioration in memory severe enough to impair a person’s ability to complete daily tasks. Alzheimer’s disease is responsible for 60 to 80% of cases. The second most prevalent dementia form is vascular dementia, which develops after a stroke. However, many other conditions, including some that are reversible, such as thyroid problems and vitamin deficiencies, can cause dementia symptoms. Dementia is frequently mislabeled as “senility” or “senile dementia,” reflecting the erroneous idea that significant mental deterioration is a natural aspect of aging.

Facts about Alzheimer’s Disease

1) Alzheimer’s Disease is not contagious

2) Alzheimer’s Disease cannot be cured

3) 10 million people are living with Alzheimer’s Disease worldwide

How Can I Prevent Alzheimer’s Disease from Making Me a Victim?

Alzheimer’s disease is a progressive neurological condition. It slowly destroys the memory and thinking skills of its victims. The risk of getting it can be reduced by avoiding certain factors known to increase the risk of Alzheimer’s Disease. Age, family history, diabetes, high blood pressure, obesity, and heart disease are all variables that enhance the risk of Alzheimer’s disease. Eating a good diet, being physically active, and avoiding smoking cigarettes are lifestyle choices that may minimize the chance of acquiring Alzheimer’s Disease.

A better way to avoid Alzheimer’s Disease is to take care of your health in all ways possible.

Conclusion

Alzheimer’s disease destroys brain cells and causes memory loss, confusion, mood swings, etc. With the proper treatment, Alzheimer’s can be prevented or slowed down.
