What is Alzheimer’s disease?

Alzheimer’s disease is also known as Senile Dementia.

A chronic neurological condition that causes the brain to shrink (atrophy) and death of brain cells in Alzheimer’s disease. The most prevalent form of dementia is Alzheimer’s disease-a continuous deterioration in thought, mental, and social abilities that influence the capacity of an individual to work independently.

About 5.8 million persons aged 65 and over in the United States struggle with Alzheimer’s disease. For such, 80% are aged 75 and over. It is estimated that between 60% and 70% of the nearly 50 million people globally with dementia have Alzheimer’s disease.

Forgetting current events or conversations are the early symptoms of the disorder. An individual with Alzheimer’s disease may experience significant memory failure as the disease progresses and lose the ability to perform daily activities.

Medications can improve or delay the progression of symptoms temporarily. Sometimes, these medications may help persons with Alzheimer’s disease maximize function and retain mobility for a period of time. Different systems and resources can help assist individuals and their families with Alzheimer’s disease.

There is no therapy that prevents Alzheimer’s disease in the brain or improves the mechanism of the disease. Complications with a serious lack of brain activity such as dehydration, malnutrition, or inflammation end in mortality in advanced phases of the disease.

What are the Stages or Types of Alzheimer’s disease?

Alzheimer’s is a progressive disease, which means the symptoms will gradually worsen over time. Alzheimer’s is broken down into seven stages:

  • Stage 1. There are no symptoms at this stage but there might be an early diagnosis based on family history.
  • Stage 2. The earliest symptoms appear, such as forgetfulness.
  • Stage 3. Mild physical and mental impairments appear, such as reduced memory and concentration. These may only be noticeable by someone very close to the person.
  • Stage 4. Alzheimer’s is often diagnosed at this stage, but it’s still considered mild. Memory loss and the inability to perform everyday tasks is evident.
  • Stage 5. Moderate to severe symptoms require help from loved ones or caregivers.
  • Stage 6. At this stage, a person with Alzheimer’s may need help with basic tasks, such as eating and putting on clothes.
  • Stage 7. This is the most severe and final stage of Alzheimer’s. There may be a loss of speech and facial expressions.

As a person progresses through these stages, they’ll need increasing support from a caregiver.

What causes Alzheimer’s disease?

We do not understand exactly the precise causes of Alzheimer’s disease. Yet brain proteins fail to act properly at the fundamental level, which interferes with the role of brain cells (neurons) and causes a sequence of toxic events. Neurons are fried, break ties to each other, and inevitably die.

Scientists agree that Alzheimer’s disease is triggered by a blend of genetic, lifestyle, and environmental influences that influence the brain over time with most individuals.

Alzheimer’s is triggered less than 1 percent of the time by specific genetic variations that practically ensure a person will experience the disorder. Such uncommon events typically lead to the onset of illness in middle age.

In the area of the brain that regulates memories, the damage most commonly starts, but the process continues years before the first symptoms. Neuron damage extends to other areas of the brain in a very repetitive fashion. The brain has greatly shrunk by the late stage of the disorder.

The function of two proteins is the subject of researchers seeking to understand the cause of Alzheimer’s disease:

Plaques. A part of a larger protein is a beta-amyloid. They tend to have a detrimental effect on neurons and to interrupt cell-to-cell connectivity as these fragments swarm together. These fragments, which can contain other cellular debris, create larger deposits called amyloid plaques.

Tangles. Tangles. Tau proteins play a role in the internal support and distribution mechanism of a neuron for the transport of nutrients and other essential materials. Tau proteins change form in Alzheimer’s disease and assemble themselves into complexes called neurofibrillary tangles. The tangles obstruct the mechanism of transport and are harmful to cells.

What are the symptoms of Alzheimer’s disease?

  • The primary symptom of Alzheimer’s disease is memory loss. Early signs include problems recalling previous occurrences or conversations. Memory impairments intensify as the condition develops, and other symptoms develop.
  • An individual with Alzheimer’s disease can at first be conscious of having trouble recalling stuff and organizing thoughts. It could be more possible that a family member or friend would note how the symptoms intensify.

Alzheimer’s disease-related brain changes contribute to growing difficulty with:

  • Memory
  • All have intermittent lapses in memory, but Alzheimer’s disease-related memory loss continues and worsens, affecting the ability to function at work or at home.

People suffering from Alzheimer’s may:

  • Repeat statements and questions over and over again
  • Forget meetings, appointments, or tasks, and don’t recall them later.
  • Routinely misplace belongings, sometimes positioning them in illogical ways.
  • Get lost in common locations
  • Finally, forget the names of members of the family and daily items
  • Had difficulty locating the right phrases to recognize objects, convey thoughts or engage in discussions
  • Reasoning and thinking
  • The disorder of Alzheimer’s causes trouble focusing and remembering, especially about abstract concepts such as numbers.
  • Multitasking is extremely difficult and juggling finances, maintaining cheque book and paying bills on time can be overwhelming. An individual with Alzheimer’s can ultimately be unable to understand and cope with figures.
  • Make decisions and rulings
  • In daily cases, Alzheimer’s triggers a deterioration in the capacity to make sound choices and conclusions. For instance, in social interactions, a person can make bad or odd choices or wear clothes that are inappropriate for the weather. Responding quickly to daily challenges, such as food burning on the stove or unpredictable driving conditions, can be more challenging.
  • Planning and carrying out familiar roles
  • As the disease progresses, once-routine tasks that require concurrent interventions, such as preparing and cooking a meal or playing a favourite game, become a challenge. Eventually, people with advanced Alzheimer’s frequently forget how simple activities like dressing and bathing can be done.
  • Personality and behavioural changes

Moods and behaviours may be changed by brain changes which occur in Alzheimer’s disease. The following can contain problems:

  • Depression
  • Apathy
  • Social Detachment
  • Swings in mood
  • Distrust of other people
  • Irritability and being violent
  • Sleeping habits alter
  • Wandering Wandering
  • Inhibition deficiency
  • Delusions, such as thinking there was something stolen
  • Preserved talents
  • For prolonged times, certain major abilities are retained even though symptoms escalate. Reading or listening to books, sharing stories and recalling, singing, listening to music, dancing, painting, or performing crafts can be retained talents.
  • These abilities can be retained longer because they are regulated later in the process of the disease by areas of the brain affected.

What are the Complications of Alzheimer’s disease?

Treatment for other health problems can be compounded by memory and language loss, poor judgement and other neurological differences induced by Alzheimer’s. It could be difficult for a person with Alzheimer’s disease to:

  • Communicate that he or she has suffering
  • Explain the signs of another condition
  • Follow a recommended course of care
  • Explain the side impacts of drugs
  • When Alzheimer’s disease progresses to the final phase, bodily processes, such as swallowing, balance, and bowel and bladder control, continue to be impaired by brain changes.

Such impacts will increase susceptibility to additional health issues, such as:

  • Inhaling the lungs with food or fluids (aspiration)
  • Pneumonia, measles and other diseases
  • Falling
  • Fractures
  • The bedsores
  • Dehydration or starvation
  • Diarrhoea or constipation
  • Dental conditions such as sores in the mouth or tooth loss

What are the risk factors for Alzheimer’s disease?


The biggest known risk factor for Alzheimer’s disease is a rise in age. Alzheimer’s is not a part of natural ageing, but the risk of having Alzheimer’s disease rises as you get older.

One research, for instance, showed that there were four new diagnoses per 1,000 individuals aged 65 to 74, 32 new diagnoses per 1,000 individuals aged 75 to 84, and 76 new diagnoses per 1,000 individuals aged 85 and older last year.

History and Genetics of Families

When a first-degree spouse, a parent or sibling, has the disorder, the chance of getting Alzheimer’s is much greater. The majority of Alzheimer’s genetic processes within families remain mostly unknown, and the genetic causes are possibly complex.

A variant of the apolipoprotein E gene is one better known genetic factor (APOE). A gene mutation, APOE e4, raises Alzheimer’s disease risk. An APOE e4 allele is borne by about 25 percent to 30 percent of the population, but not all with this gene mutation experiences the disorder.

Scientists have established unusual variations (mutations) in three genes that practically ensure that Alzheimer’s will evolve in a person who inherits one of them. Yet less than 1 percent of patients with Alzheimer’s disease qualify for these mutations.

Down’s Syndrome

Alzheimer’s disease is evolving in many individuals with Down syndrome. This is possibly due to having three copies of chromosome 21 and then three copies of the protein gene that contributes to beta-amyloid development. Alzheimer’s signs and symptoms in individuals with Down syndrome tend to manifest 10 to 20 years older than in the general population.


There tends to be no risk differential between males and females, but, overall, there are more females with the disease because they live longer than males in general.

Mild cognitive deficit

Mild cognitive disability (MCI) is a reduction in memory or other reasoning ability that is higher than average for the age of an individual, but the decrease does not preclude a person from working in social or work settings.

There is a substantial chance of developing dementia in individuals who have MCI. The disorder is more likely to lead to dementia due to Alzheimer’s disease because the main MCI deficit is memory. An MCI diagnosis facilitates a stronger emphasis on improvements in the healthier diet, creating methods to prepare for memory loss and making daily medical visits to track symptoms.

Trauma to the brain

The risk of Alzheimer’s disease is higher among those who have had serious brain injuries. Several major trials have shown that the risk of dementia and Alzheimer’s disease has risen in persons aged 50 years or older who have had a traumatic brain injury (TBI). In persons with more serious and multiple TBIs, the risk increases. Some reports suggest that, within the first six months to two years after TBI, the risk could be greater.

Polluting the climate

Animal experiments have demonstrated that particulates from air emissions can worsen the degeneration of the nervous system. And human studies have shown that exposure to air pollution is associated with a higher risk of dementia, especially from traffic emissions and burning wood.

Excessive intake of alcohol

Drinking significant doses of alcohol has been known to induce changes in the brain for a long time. Several major trials and reviews have found that alcohol use disorders, especially early-onset dementia, are related to an increased risk of dementia.

Bad habits of sleep

Study has found that poor sleep habits are associated with an increased risk of Alzheimer’s disease, such as problems falling asleep or remaining asleep.

Cardiac fitness and lifestyle

The same risk factors associated with heart disease may also raise the risk of Alzheimer’s disease, study has shown. They include:

Lack of exercises


Smoking or Secondhand Smoke Consumption

Blood Pressure Strong

Cholesterol Heavy

Poorly regulated diabetes type 2

Such variables can all be changed. Changing lifestyle patterns will also change the risk to some degree. For example, a reduced chance of contracting Alzheimer’s disease is associated with frequent exercise and a balanced, low-fat diet rich in fruits and vegetables.

Lifelong learning and civic interaction

A correlation between lifelong activity in mental and socially stimulating behaviours and a decreased risk of Alzheimer’s disease has been identified in the research. Poor levels of education (less than high school) tend to be a risk factor for Alzheimer’s disease.

How is Alzheimer’s disease diagnosed?

The following assessments will definitely require a medical work-up:

  • Neurological and physical review
  • By evaluating the following, the doctor will conduct a physical assessment and possibly determine general neurological health:
  • Reflexes Reflexes
  • Tone of muscle and strength
  • Capacity to stand up and walk around the room from a chair
  • Sense of vision and of listening
  • Coordination
  • Equilibrium
  • Tests from labs

Your doctor will be able to rule out other likely sources of memory loss and uncertainty, such as thyroid deficiency or vitamin shortages, by blood testing.

  • Mental status and research of neuropsychology
  • To measure memory and other thought skills, your doctor can give you a brief mental status examination. Compared with people of a comparable age and education level, longer types of neuropsychological testing can offer more information about mental activity. These assessments will help to develop a diagnosis and act as a point of departure to control symptom development in the future.

Imaging the cortex

  • Photos of the brain are also primarily used to detect noticeable abnormalities linked to disorders other than Alzheimer’s disease that can induce neurological change, such as strokes, injuries or tumours. Currently used only in major medical centres or in clinical trials, new imaging applications can enable doctors to diagnose complex brain changes caused by Alzheimer’s.

Brain function imaging involves the following:

  • Magnetic Resonance Imaging (MRI). Radio waves and a heavy magnetic field are used by MRI to create accurate brain images. While they may show brain shrinkage of brain regions associated with Alzheimer’s disease, MRI scans also rule out other conditions. An MRI is generally preferred to a CT scan for the evaluation of dementia.
  • Computerized Tomography (CT). A CT scan, a specialized X-ray technology, produces cross-sectional images (slices) of your brain. Tumors, strokes and brain trauma are generally used to rule out this.
  • Imaging of disease processes can be performed with positron emission tomography (PET). A low-level radioactive tracer is inserted into the blood during a PET scan to show a special function in the brain. The following can require PET imaging:
  • PET scans of fluorodeoxyglucose (FDG) reveal regions of the brain where nutrients are poorly metabolised. Identifying degeneration patterns, regions of low metabolism may help discern between Alzheimer’s disease and other causes of dementia.
  • The burden of amyloid deposits in the brain can be measured by Amyloid PET imaging. This imaging is mostly used in research but can be used if a person has signs of dementia that are unusual or very early in onset.
  • Tau PET imaging, which measures the burden of neurofibrillary tangles in the brain, is generally used in the research setting.
  • In special circumstances, such as rapidly progressive dementia, dementia with atypical features or early-onset dementia, other tests may be used to measure abnormal beta-amyloid and tau in the cerebrospinal fluid.
  • Future examinations for diagnosis
  • Researchers are working to develop tests that can measure biological signs of disease processes in the brain.
  • These tests, including blood tests, may improve the accuracy of diagnoses and enable earlier diagnosis before the onset of symptoms. A blood test for Plasma Aβ is currently available and recently received certification in the U.S. by the Centers for Medicare & Medicaid Services to allow distribution on the market.
  • Genetic testing generally isn’t recommended for a routine Alzheimer’s disease evaluation. The exception is people who have a family history of early-onset Alzheimer’s disease. Meeting with a genetic counsellor to discuss the risks and benefits of genetic testing is recommended before undergoing any tests.

What is the treatment for Alzheimer’s disease?


New treatments for Alzheimer’s can aid with memory symptoms and other neurological improvements for a while. For the management of neurological symptoms, two types of medications are commonly used:

Inhibitors of Cholinesterase. By retaining a chemical messenger that is depleted by Alzheimer’s disease in the brain, these drugs function by improving levels of cell-to-cell connectivity. Typically, these are the first drugs tried, and most persons show slight changes in symptoms.

Neuropsychiatric effects, such as anxiety or depression, can also be strengthened by cholinesterase inhibitors. Cholinesterase inhibitors widely recommended include donepezil (Aricept), galantamine (Razadyne) and rivastigmine (Exelon).

Diarrhea, fatigue, lack of appetite and sleep disturbances are the major side effects of these medications. Severe side effects can include cardiac arrhythmia in people with such heart diseases.

Memantine. This medication acts through another network of brain cell connectivity and delays the development of mild to extreme Alzheimer’s disease symptoms. It is often used with a cholinesterase inhibitor in conjunction. Dizziness and confusion include relatively rare side effects.

Other drugs can also be used to help manage the behavioural problems associated with Alzheimer’s disease, such as antidepressants.

Develop a safe and welcoming community

A major aspect of every recovery strategy is to tailor the living environment to the needs of a person with Alzheimer’s disease. Establishing and reinforcing routine routines and eliminating memory-demanding activities will make life much smoother for those with Alzheimer’s.

To help a person’s sense of well-being and continued ability to work, you should take these steps:

  • Keep keys, wallets, cell phones and other valuables in the same location at home at all times, so that they are not misplaced.
  • Store drugs in a healthy spot. Keep track of dosages by using a daily checklist.
  • Arrange for automated billing and automatic deposit to be on accounts.
  • Make an Alzheimer’s patient bring a location-capable cell phone so that a caregiver can watch their location. Significant phone numbers are coded into the phone.
  • On doors and walls, mount warning sensors.
  • Be sure that as many daily appointments as possible are taken at the same time on the same day.
  • To track everyday routines, use a calendar or whiteboard in the house. Develop the habit of finished tasks being crossed off.
  • Remove unwanted furniture, throw rugs and clutter.
  • On stairways and in toilets, add durable handrails.
  • Ensure that you are secure with sneakers which slippers and have sufficient grip.
  • Reduce the mirror count. In mirrors, people with Alzheimer’s can find photos disturbing or terrifying.
  • Be sure the person with Alzheimer’s holds or wears a medical alarm band with identification.
  • Keep images around the house and other meaningful items.

How can Alzheimer’s disease be prevented?

You should help your child develop strategies of self-care that can carry into adulthood:

  • Using poor vision aids in the classroom, such as a hand-held magnifying glass, a monocular or a magnifier connected to lenses, and a tablet synced to a smartboard (a touch-screen digital computer board).
  • Always use sunscreen that protects against both UVA and UVB light with a sun protection factor (SPF) of 30 or greater.
  • Avoid high-risk or extended sun exposure strictly, such as being outside for long stretches of time or in the middle of the day, at high altitudes, and with thin cloud cover on sunny days.
  • Wear protective clothes, including colourful clothing, such as long sleeves, collared jackets, long trousers and gloves, wide-brimmed hats, and special clothing for UV protection.
  • Cover the eyes with dim, UV-blocking sunglasses or transition lenses that darken under bright light.
