Alzheimer s disease is a neurological, irreversible, progressive brain disorder. It is a chronic neurodegenerative dementia that causes the death of brain cells, causing memory loss and cognitive decline. It affects a person s thinking and behavior. The symptoms develop slowly and get worse as time passes.

Causes:
As it is a kind of dementia, Alzheimer s is caused by the death of brain cells. Over a course of time, brain cells die progressively and at the end, the tissue is left with fewer nerve cells and connections. As a result, the total brain size shrinks. Tiny inclusions called plaques and tangles can be seen in the postmortem. These cannot be seen or tested in a living Alzheimer s affected brain. These plaques are given the name  amyloid plaques  because they are found among the dying cells of the brain when a protein called beta-amyloid builds. The tangles stay in the neurons; they are formed from a protein called tau.

There are several reasons behind all this, some of which are listed below-

Anti-anxiety medications
Hitting on the head too many times
Regularly sleep-deprived
Loneliness
Diabetes in the brain
Old age
Genetic line
Down s syndrome
Cardiovascular diseases
Symptoms:
Alzheimer s disease damages the brain, so the clinical signs and symptoms begin to show very early. The symptoms are-

Memory loss
Agitation and mood swings
Poor judgment
The trouble with money calculations
Difficulty doing familiar tasks
Trouble in planning or solving a problem
Confusion with time and place
Difficulty in communicating
Loss of motivation
Inappropriate behavior
Aggressive personality
Childlike behavior
Preventing Alzheimer s disease:
Alzheimer s disease ultimately results in death. Even if there are treatments, they cannot fully cure it. So it s better to try to prevent it before it happens. Ways to prevent Alzheimer s disease are-

Eating more fruits and vegetables.
Eating berries every day.
Increasing omega-3 fatty acids.
Taking folic acid supplements.
Drinking grape juice or red wine with evening meal.
Doing the Mediterranean style diet.
Controlling the blood pressure.
Having strong social support.
Treatment of Alzheimer s disease:

Treatment of Alzheimer s disease is a long time process.
First of all, doctors perform a physical exam to check the overall neurological health. By this, they check muscle strength, reflexes, walking ability, sense of sight and hearing, coordination and balance.
Then comes the blood test to find the cause of confusion and memory loss by checking the thyroid disorder and vitamin deficiency.
Then they perform the neuropsychological test and check the mental status.
Then there are other tests, like MRI, CT, and PET.
After all this, drugs are given and a safe and supportive environment is created with proper exercise and nutrition.
Alzheimer s disease is undoubtedly the worst kind of disease. Hence, it is highly recommended to contact a doctor as soon as any symptom is noticed.

All About Alzheimer's Disease!

With age, most body organs begin to deteriorate in their function. This happens to the brain also, thereby reducing the overall speed of functioning of most organs. While slowing of bodily movement is visible, the internal organs functioning also slows down, which is not that obvious. Memory loss or dementia is one of the main manifestations of this degeneration of the brain.

Alzheimer s is the most common form of dementia, and the associated symptoms includes reduced reasoning abilities and cognitive defects. Though it is seen only in the elderly, not all elderly people will have Alzheimer s. The overall quality of life of the affected person is reduced with difficulty remembering things that were recently learned. It is a progressive disease and as it gets more severe, a full-time caretaker may be required.

Causes: The brain cells are affected by protein masses known as plaques and tangles. These hamper the way communication between the brain cells happens as well as affect nutrition from reaching all parts of the brain. This leads to shrinking of the brain, eventually leading to memory loss and other problems. There is also a strong genetic linkage, as most people with Alzheimer s have the lipoprotein A gene.

Symptoms: Though memory loss is the most common symptom, there are other symptoms:

Being confused about places, people, and times
Inability to find the right words during conversations
Regular objects are misplaced
Becoming irritable, (in someone who was not so previously)
Mood swings
Personality changes
Inability to organise thoughts
Not able to make the right decisions
Repetitive talks and actions
Forgetfulness (not something the person always does)
Difficulty with numbers (again, not something calculations
Difficulty managing everyday tasks and minor problems
Suspicion of others (like immediate family members and friends)
Risk factors: While age is definitely a risk factor, the fact that not all aged people develop Alzheimer s is to be borne in mind. Other risk factors include the history of stroke, high cholesterol, high blood pressure, diabetes, smoking, obesity, and poor lifestyle choices.

Diagnosis: While there is no definitive way to diagnose Alzheimer s, symptoms along with brain scans and neuropsychological function testing are useful ways to confirm the diagnosis.

Treatment: This is aimed at two things reducing the rate of disease progression and treat (or reverse) symptoms if possible.

Cholinesterase inhibitors improve cellular communication in the brain and also manage depression and agitation. Memantine is used to slow the pace of disease progression.
In people with the disease, small changes are useful to help them with the symptoms. These include keeping essential things like keys and wallet in the same place, keep a daily diary to help them remember things, keep pictures of friends and family within visible distance.

Alzheimer's - An Overview!

Alzheimer's disease is a neurological problem that is characterised by a cognitive decline and memory loss. It is a type of neurodegenerative dementia. The symptoms of alzheimer's disease include not being able to absorb and retain new information, lack of reasoning and judging, not being able to take on complex tasks, impaired visuospatial abilities, problems in reading, writing and speech, among many others. If a person has at least two of these symptoms in a debilitating manner, then the diagnosis can be made in favour of alzheimer's disease. The main causes of alzheimer's are shrinkage of the brain size and death of the brain cells. The immune system is also said to trigger this neurodegenerative disease. Let us find out what medical science has found so far.

1. Connections: many a times, in alzheimer's disease, the memory and behaviour of the person changes because the brain is unable to make proper neural connections which can lead to memory loss of how a person behaved and the elements that formed the basis of the patient's cognition. Apparently, the immune system behaves in the same way within the brain and blocks the connection. This happens because there is constant communication between the brain and immune system along neurological lines, which is where the disease first emanates.

2. Inflammation: the brain is prone to inflammation or swelling that is not the normal kind. This inflammation happens as a result of the activation of the infection fighting neurotransmitters and the chemical changes that happen in the brain when an infection strikes. The inflammation usually happens in the plaques or clumps which the brain tries to protect. These clumps are made up of a protein called amyloid. The immune system is responsible for creating this inflammation in the brain of the patient.

3. Pattern recognition receptors: many of these receptors work in different manners and cooperate with each other to create a response in the brain. These prrs can be found in the brain plaques, and they develop the signs of danger which further fuels the inflammation in the brain as a matter of protection.

4. Activation of cells linked with the immune system: when the prrs begin to respond, it basically activates the immune system and the cells of the same. This is the basic reaction that causes the changes in brain which then leads to the attachment of the protein to the tissue that is diseased, in which case alzheimer's disease starts. The inflammation that we had spoken about earlier basically happens in the nervous tissue.

It is important to recognise and act on the initial signs of alzheimer's disease before it progresses beyond one's control.

Can the Immune System Trigger Alzheimer's Disease

Dementia refers to the progressive loss of memory in a human being. It does not refer to any particular disease. It is rather a cumulative representation of symptoms which signify that the person is losing his or her memory. Dementia occurs in seven stages. Read on to read more about them:

In the first stage, there is no cognitive decline and the person is mentally sound. There is no memory loss as well.
In the second stage, there is a very mild cognitive decline leading to normal forgetfulness that is often associated with progressing age.
In the third stage, there is a mild cognitive decline. The person has an increased forgetfulness and may find it difficult to concentrate on things.
In the fourth stage, there is moderate cognitive decline and the person starts forgetting even the most recent events. They cannot even travel alone or manage their own finances.
In the fifth stage, there is moderately severe cognitive decline. The person going through this stage often requires help even with their daily activities. People tend to forget even the most common things like phone and email passwords.
In the sixth stage, there is severe cognitive decline. This stage is also called middle dementia and there is prominent memory loss. People cannot even count from 1 to 10. Their speech becomes slurry. They also start having delusions.
In the seventh stage, there is very severe cognitive decline. This stage is also called late dementia. The psychomotor skills are also lost at this stage and the person may not even be able to walk properly.
Some of the early signs of dementia are listed below:

In the initial days of dementia, the person usually tends to get confused when it comes to choosing the right words. This makes them take much longer time to conclude their speech.
There might also be a change in the mood of the person.
Depression is also one of the early signs.

The person will have a tendency to forget even the most recent events that took place in his or her life. This means that they might remember what happened ten years before but they might not remember what they did in the morning.
Early signs also include failure to sense directions. People often tend to forget their addresses and the landmarks and thus become lost when they travel alone.
Confusion is also one of the common signs and this is directly correlated to the loss of memory because when a person cannot remember familiar faces, it leads to a lot of confusion within his own mind.
So, if you suspect that someone in your house is suffering from dementia, then you must look out for these early signs and seek medical help immediately. Early treatment can keep the condition from worsening.

Dementia - Stages and Early Signs!

Alzheimer's disease is a dynamic disease that causes loss of memory and other vital mental functions. To start with, someone with Alzheimer's disease may witness light confusion in the beginning and trouble recalling. In the long run, individuals with the disease may even overlook important individuals in their lives and experience emotional identity changes.

Dementia: Alzheimer s disease is the most widely recognised reason for dementia   a gathering of brain issues that causes the loss of intellectual and social abilities. In Alzheimer's disease, the brain cells deteriorate and die, bringing on an enduring decrease in memory and mental capacity.
Brain Cells: Despite the fact that the reasons for Alzheimer's is not yet completely comprehended, its impact on the brain is clear. Alzheimer's disease harms the brain cells. A mind influenced by Alzheimer's has fewer cells and fewer associations among surviving cells than a solid mind.
Brain Shrinkage: As more brain cells start to die, Alzheimer's prompts critical brain shrinkage. At the point when specialists inspect Alzheimer's brain tissue under the magnifying instrument, they see two sorts of irregularities that are considered to cause Alzheimer s. These are:
Plaque: These clusters of a protein called beta-amyloid may harm and crush brain cells in a few ways, meddling with cell-to-cell functioning. In spite of the fact that a definitive reason for brain cell passing in Alzheimer's is not known, the accumulation of beta-amyloid on the outside of brain cells is a prime reason.
Tangles: Brain cells rely upon an inner support and transport framework to carry the supplements and other fundamental materials through their long extensions. This framework requires the typical structure and working of a protein called tau. In Alzheimer's, strings of tau protein turn into strange tangles inside the brain cells. This may also cause the decrease of brain cells. 
Here are some more causes that can lead to this disease:

Age: Age is a most critical cause in the development of Alzheimer's disease. The probability of building up the condition increases after you reach sixty-five years of age.
Family history: The qualities you acquire from your parents can add to your danger of building up Alzheimer's infection. This may also contribute to the environmental factors which can cause this condition. In some families, a single gene creates Alzheimer s disease and the dangers of the condition being passed on are much higher.
Head injuries: Individuals who have had serious head damage have been observed to be at higher risk of building up Alzheimer's disease.
Cardiovascular diseases: Research demonstrates that few lifestyle components and conditions connected with cardiovascular disease can build the danger of Alzheimer's disease. These include smoking, obesity, diabetes, hypertension and high cholesterol.


Alzheimer's Disease - Reasons That Can Lead To It!

Ageing is inevitable, and as much as we want to escape, there is no way out. All organs, whether obvious or not, undergo gradual degeneration and deterioration. The brain is no exception, and memory being one of its main function also begins to decline with age. There are various factors which determine how quickly this ageing sets in and how rapidly it progresses. These are dictated by a person s lifestyle, activity levels, and overall body changes. Dementia also has a strong family history, and if you know someone who has a family history, there are some early signs that you could watch for. This will help in both empathizing with the person, as well as to help in arresting progression. Read on to know the signs that need to be watched out for.

Mood changes: Sudden changes in mood, especially going into short periods of depression without an obvious reason, is one of the first symptoms of dementia. If it is happening repeatedly, this can help identify dementia.
Personality changes: If a shy person suddenly becomes outgoing or vice versa, this could be an early indicator of dementia. They either develop or shed inhibitions, which is a new change for them.
Memory loss: Sudden short-term memory loss for a person who had a very strong memory is a definite indicator of dementia. They might clearly remember the distant events but forget small things like where to find their medicines, where things are in the kitchen or bathroom, etc. Because of this, you might see them repeating what they just did. This could be like washing a glass again, saying or asking the same thing again, etc.
The difficulty with regular tasks: Short-term memory loss causes difficulty with regular tasks like laying out the dinner table, finding regular medicines, paying utility bills, etc. There is also difficulty in learning new tasks, which further complicates things.
Feeling lost: Due to sudden memory loss and difficulty with regular tasks, they suddenly feel lost, which in turns adds to their depression.
Apathy: This also leads to a general lack of interest in things and people around them. They could have had hobbies, which no longer interest them.
Disoriented: They find it difficult to be aligned to time and space. Directions which they clearly know could seem difficult.
Not able to connect the dots: While the elderly people are generally good at telling stories and anecdotes, with dementia setting in, this becomes difficult.
These are some symptoms which can help identify if a near one is slowly developing dementia. Identifying in the early stages can help in arresting progress and extending support.
