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

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.

Dementia - How To Know If Someone Is Suffering From It?

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!

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!

Parkinson s disease is a disorder involving the nervous system. It can start with a mere tremor of one hand and advances to slow movement and stiffness. The face might show little no symptoms in the beginning but the speech might become slurred. With every passing day, the condition worsens. This condition has no permanent cure but the symptoms can be improved with proper medication.

What are the symptoms?
Some unmistakable symptoms include the following:

A sudden shaking of the limb. A sudden tremor of the hand is a very common symptom of this disease.
Stiffness of the muscles that can limit the range of motion and sharp pain.
The posture of the body might get compromised. Often balancing problems are witnessed among many patients.
There could be problems with speech leading to soft, slurry or quick speech. The speech in some cases can become monotonous devoid of inflexions.
Parkinson s disease can lead to slow movement and makes performing of simple tasks difficult.
Patients often find writing very difficult
What are the possible causes of Parkinson s disease?

Specific genetic mutation can lead to Parkinson s disease in folks who have a family history of Parkinson s disease. Certain variations of the gene increase the risk of this disease
Exposure to certain environmental factors or certain toxins can trigger Parkinson s disease in an individual.
Certain cells in the brain known as Lewy bodies can trigger Parkinson s disease.
A certain kind of protein cells within the brain known as alpha-synuclein can trigger the Parkinson s disease in an individual
What are the risk factors?

Heredity: Having an immediate family member or close relative suffering from Parkinson s disease can increase the risk of getting this disease in an individual
Age: Although not a prime risk factor, but an individual over the age of over 60 have an increased risk of getting this disease
Toxins: Exposure to pesticide or certain herbicide increase the risk of Parkinson s
Sex: Men are more likely to get Parkinson s disease than women
What is the medication for Parkinson s disease?

Carbidopa-levodopa: This is a natural chemical that gets passed to the brain and is converted to dopamine by the body. The benefits of this medication might reduce with increased symptoms.
Carbidopa-levodopa infusion: A popular drug in this category is known as the Duopa. It is administered directly into the small intestine in the form of gel through a feeding tube.
MAO-B inhibitors: Drugs from this group include rasagiline and selegiline. This is powerful medicine. Many patient experiences hallucination during the initial days of consuming these drugs.
Anticholinergics: This medication is mainly used to counter tremors of the limbs in the early stage of Parkinson s disease.

Parkinson's Disease - Know The Risks Involved!

Depression is possibly regarded as the first sign of Alzheimer s disease. According to a research, the connection between Alzheimer s disease and depression is very interesting. It has been found that the life of people who are suffering from dementia is affected in 2 different ways. Individuals who have suffered from depression in their lives are at a greater risk of developing dementia. It has also been observed that people suffering from dementia also have depression. The health condition should be treated immediately because if it is ignored it can damage the quality of life and result in worst conditions like memory loss. Temperament, as well as behavioral changes, may precede memory problems in people with the disease.

Risk factor of dementia
The significant risk factor for dementia or common form of Alzheimer s is developing depression at a younger age. The other reasons for the link are not very clear, however, it has been speculated that the inflammation that occurs in depression is a contributing factor to the Alzheimer s disease. The risk of dementia also increases with certain proteins which spiral with depression. The common signs of Alzheimer s disease include lack of appetite, sadness, agitation, weight loss, and anxiety. People suffering from this condition are unable to tell if they are depressed, but their actions help in communicating a message. It is always better to seek the assistance of a physician as doctors can make use of tools to assess the neurological disorder.

Best way to treat patients with Alzheimer s
The best way to treat patients suffering from dementia and who are depressed is to engage them in activities. It is important that they step out and do some exercises. They should go out in the sunshine. It is necessary to engage them in activities and conversations and help them to lead a higher quality of life. Some of the symptoms of dementia and depression are alike but not all of them. The major symptoms of depression include feeling tired most of the times, feeling restless, irritable, feeling worthless/guilty, unplanned weight gain and trouble in focusing. These symptoms often occur for more than 2 weeks or longer.

Difficulties caused by Alzheimer s disease
In the case of Alzheimer s disease, it becomes very difficult for the individual to communicate, learn or remember mainly because the damage is caused to the brain. Due to the brain damage, there is a possibility of changes in the personality and moods of individuals suffering from this health condition. The quality of life is affected by depression as well as Alzheimer s disease. Hence, it is always better to treat the condition immediately. For that reason, it is very important to set up a pleasant environment around and help patients suffering from this condition by helping them do enjoyable tasks and make them feel positive about life.
