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 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!

A lot of things can be done to cope with the initial stages of dementia. A person goes through a wide range of emotions such as fear, denial, frustration, and anger, post the diagnosis. Here is a list of tips that will help a patient with dementia to cope better:

Physical health: For a dementia patient, it is very important to take care of one s health. A good diet along with regular exercise and adequate rest is a prerequisite to manage this disorder.
Regular check-ups: Regular medical check-ups with the doctor are necessary in this condition. Depression and other mental health problems should be discussed with a professional.
Quit alcohol: Alcohol might give momentary pleasure from the misery, but it has long-standing implications. It reacts with the medicine and creates additional health and memory-related complications.
Allocate time for difficult tasks: With time, it can become difficult to perform even the simplest of tasks. The patient should accordingly schedule the time to perform the tasks which may be difficult to carry out. Adequate breaks should be taken while performing a task to avoid getting fatigued.
Redefine work: If a patient is suffering from dementia is still working, it should be ensured that the work is more manageable from a desk. Planning an early retirement may be a good idea in order to cope with dementia.
Be organised: Keeping track of things can get difficult with time. It, therefore, makes sense to organise all belongings systematically. Putting labels on doors and drawers also help.
Continue pursuing your hobbies: Amidst the difficulty and the depression, it is a good idea to continue doing things that are fun. While such activities might require some assistance from the doctor and family members, this helps the patient to be cheerful and healthy.
Maintain notes: Since dementia is involved with forgetfulness, it makes sense to maintain a diary and keep records of phone numbers, people, appointments, etc.
Communication channel: Maintaining a direct communication channel with family, friends, and relatives is a good idea. Sharing feelings will go a long way in maintaining relations with loved ones.
Support group: Joining a dementia support group can be highly beneficial for the patient. It will not only give the patient company but also make sure that the patient gets a lot of useful information about the disorder. It also helps in keeping the morale up.
Getting ready for the future: Things need to be meticulously planned well in advance to ensure that when the disease progresses, the patient has enough people to look after him. Things such as medical arrangements, financial assets, and property details should be carefully handed over as per the patient's wish. This will ensure a smooth run of the patients  life when they can no longer take care of themselves.

Dementia - Easy Tips To Help You Cope With 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.
