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 cannot be singularly regarded as a specific disease, but rather indicates a group of symptoms associated with your memory, cognitive thinking, and social abilities, up to the point where daily functioning gets affected. In most cases, dementia steadily worsens over time (progressive dementias). Dementia is not to be confused with memory loss alone; because it is natural with old people to experience memory loss, but that does not necessarily mean they have dementia. If the reason is dementia, then you may require medical treatment.

Causes

Dementias are generally caused either by damage to or changes in the nerve cells operating in the brain. The causes can be grouped differently based on the type of dementia experienced and the part of the brain affected. While some causes can be reversed with effective treatment, others, unfortunately, cannot.

The most common causes of dementia which cannot be reversed include:

1. Alzheimer's disease
2. Vascular dementia
3. Parkinson's disease
4. Frontotemporal dementia
5. Dementia with Lewy (dementia which is neurodegenerative and progressive in nature) bodies
6. Severe head injuries

Other irreversible causes which are relatively rarer than usual include:

1. Huntington's disease (breakage of the brain's nerve cells)
2. Creutzfeldt-jakob disease (irreversible and fatal brain disease)
3. Multiple sclerosis or amyotrophic lateral sclerosis
4. Infections like syphilis
5. Leukoencephalopathies (diseases affecting the brain's'white' areas)
6. Brain injuries
7. Multiple system atrophy

Causes of dementia which can be treated include:

1. Hypothyroidism
2. Heavy metal poisoning
3. Certain brain tumors
4. Chronic alcoholism
5. Hiv/aids
6. Vitamin b12 deficiency
7. Medicinal side effects or abnormal drug reactions
8. Normal pressure hydrocephalus
9. Certain cases of encephalitis

Symptoms

Symptoms of dementia include:

1. Memory loss
2. Difficulty finding the right words
3. Difficulty exercising judgments, especially during emergencies
4. Inability to recall particular events or to recognize people and places
5. Depression or other mood disorders, in addition to symptoms like uncontrolled aggression or constant agitation.

Causes and Symptoms of Dementia

Alzheimer s disease is one of the most severe forms of dementia that is, memory loss which also comes with other disorders such as reduced muscle movement. A patient with the Alzheimer s disease practically forgets even the most basic day-to-day activities and hence, the disease interrupts the lives of people suffering from it and the ones who are related to them. A commonly observed pattern in the patients suffering from the Alzheimer s disease is that most of them are aged 60 years and beyond. In simple words, it is the death of the brain cells, that is, the nerve cells which causes the memory loss at first and then the cognitive decline of other bodily functions.

Symptoms:

A patient of the Alzheimer s disease might show one or more of the following mentioned symptoms. Read the symptoms carefully and help identify the symptoms if you see them in anyone in your surroundings. Most people mistake this symptom to be something else which causes a delay in the diagnosis. But if the disorder is diagnosed at an early stage it might help people survive, or at least have a little longer until their memory stays intact. Therefore, it is of utmost importance to know about the symptoms that are given below:

The inability to remembering the information 
Repeating questions or actions
Unable to find the way on a rather regularly visited road
The decrease in decision-making ability
Poor judgment
Unable to solve complex puzzles or do tough activities
Unable to recognize familiar people such as colleagues and relatives
Unable to dress up properly
Inability in speaking mother tongue or word formation
Uncontrollable mood swings
Rude and un-empathetic social behavior such as being outspoken
They will be unable to maintain their own finances unlike before.
Stages of Alzheimer s disease
It is not unknown a fact when someone says that detecting a disease at an early stage is beneficial than at a later stage. The reason being that if a disease is detected earlier, there are more chances of treating it successfully, or in case of the Alzheimer s disease there are more chances of a medication to work on slowing down the adverse effects of the disease since there is no permanent cure available for it. Therefore, it is of utmost importance that one is aware of the early onset of the disease and also, the symptoms to make a quick diagnosis. The disease affects people between the age of 30 and 60, generally, the symptoms begin at the very early age of 30 but they do not become persistent before reaching a later-on stage. The three stages are:

Preclinical when the individual hasn t recorded any symptoms
The beginning with mild symptoms
Complete dementia

Alzheimer's Disease - Know Its Symptoms!

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!

One of the worst neurological disorders to have is dementia. It is a general term used to describe cognitive decline of the brain. It s not specific disease but denotes several brain disorders and mental illnesses. A person suffering from dementia can have severe impairment in judgment, loss of memory and thinking. Dementia is a very difficult disease not only for the patient but also for their families and caregivers. 

Some facts about dementia are as follows:

It s not a mental disorder occurring in old age but it does degenerates with age.
An estimation of 47.5 million people worldwide suffers from dementia and 60% of these people live in low and middle-income countries and according to WHO this figure is likely to increase.
Every 4 seconds a new case of dementia is reported
Dementia is a collective term to describe the many types of in people, such as 

Alzheimer s Disease: It is one of the most common type of dementia accounting for 60-80% of dementia case. People suffering from Alzheimer s have fewer nerve cells and the size of the brain shrinks.
Vascular Dementia: Another most common form of dementia occurring after a stroke.
Lewy Body Dementia: It is neurodegenerative condition that involves a protein called alpha-synuclein which changes the brain. Symptoms may be similar to Parkinson s disease.
Symptoms of dementia can range from mild to moderate to severe that includes:

Memory Loss
Disorientation meaning inability to focus or pay attention
Changes in visual perception
Impairment in reasoning and judgment
Dementia can be caused by damage to brain cells or progressive brain cell death. As a result communication between brain cells become difficult. Other symptoms include:

Stroke
Brain Tumor
Head Injury
Prion Disease
HIV Infection
Reversible Factors

There are no definite tests for dementia. Doctors and neurologists have to medical history, blood tests and CT scans to find out whether a person has dementia or not. However, the most potent evaluation comes from a set of questions that are asked to a patient suspected of having dementia. The ability to answer those questions correctly is one of the best diagnoses for dementia.
There is no specific treatment for dementia as it is not a curable disease and degenerates with time. However, medicines or drugs given for Alzheimer s can be given to people suffering from dementia.
Although results vary depending upon a person s lifestyle s and habits, doctors suggest eating healthy, exercising regularly, and stopping smoking and drinking may prevent some types of dementia.
The best treatment for dementia is to treat the person with care and love so that they don t feel neglected.
Dementia is often associated with old age but that is not always true. It is important to gain knowledge and educate others also.

Dementia - Quick Facts You Must Know About It!

Aging comes with many health problems including mild hearing loss. Usually, this mild hearing loss does not come alone. According to medical studies, adults, particularly males with hearing loss, mild or severe, are at a higher risk of developing Dementia and Alzheimer s disease. The risk increases as the hearing loss worsen. People with mild hearing loss are at twice the risk of developing dementia compared to people with normal hearing.

Dementia is a group of symptoms and diseases that affects the thinking, memory and social abilities that interfere with the daily functioning of an individual. However, memory loss alone does not mean that one has Dementia. Out of the many causes, Alzheimer s disease is usually the cause of Dementia. Alzheimer s disease is a progressive disease that affects the brain cells to degenerate and dies, destroying memory and other mental functions. 

How Hearing Loss Causes Alzheimer s?

According to medical studies, hearing loss causes several brain changes which increase the risk of developing Dementia. Hearing loss can lead to brain shrinkage, the process in which the section of the brain responsible for hearing becomes inactive. This condition leads to loss of tissues and alterations in the brain structure, developing as the first connection between hearing loss and Alzheimer s. Studies show that the brain of people shrinks more quickly who have hearing loss as compared to the brain of an individual with normal hearing. 

The second link created with an overwhelmed or overloaded brain. In hearing loss, the brain works overtime in understanding what others are saying. When the brain strains too much only for hearing every time and every day, it exhausts an individual s mental energy and snatches the brainpower required for other important mental functions, such as thinking, remembering and acting. This can further lead to Dementia, Alzheimer s and other mental disorders. 

Hearing Aids to prevent Dementia and Alzheimer s

According to various studies, hearing aids are not only helpful in improving one s hearing but they can also preserve an individual s mental and emotional health. Early diagnosis and treatment of a possible hearing loss help reduce risks later in life.

At times, the symptoms of undiagnosed hearing loss are mistaken with the symptoms of Alzheimer s. Hearing impairment makes it challenging for an individual to listen and respond to verbal signs. It increases the feeling of confusion, paranoia, and isolation. 

Hearing aids can relieve the symptoms of Alzheimer s. According to a study hearing aids slow down the rate of memory loss and improve an individual s quality of life.

Takeaway

Adults, especially males with hearing loss have a greater tendency of developing Dementia and Alzheimer s. Hearing loss causes brain to overwork leading to the loss of important mental functions. Hearing impairment can worsen the symptoms of Dementia and Alzheimer s. 

Hearing aids do help in improving the condition and symptoms of Alzheimer s and improve one s quality of life. A timely diagnosis can make a big difference.
