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

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?

Diagnosing dementia can be more difficult than you can imagine. Medically, the patient needs to have at least two areas of mental functionality impaired to an extent where it interferes with their everyday life. However, diagnosis is just the beginning as treating dementia can be even more challenging. Here is a look at some of the treatment options available for dementia patients.

 Treatment for Dementia
There is often no cure for most forms of dementia. Treatment relies on the management of the condition, to ensure that the progression can be impeded. With proper treatment, patients can live a relatively normal life for a number of years.

Cholinesterase inhibitors- These medications are used for the treatment of Alzheimer s disease. They are chemical agents that boost the memory and judgment of the patient. The same is also an effective medication for those suffering from Parkinson s disease and Lewy body dementia.
Therapy- Making small changes to some aspects of life of the patient can often yield good results. For instance, clearing the clutter and noise in the house can be an effective way of helping dementia patients deal with their condition. Similarly, creating a safe environment at home with little chance of severe accidents, will ensure the safety of the patient.
Stress in caregivers of dementia patients
Dementia patients need to be cared for, ideally by a close family member such as a spouse. However, these caregivers undergo a lot of stress while providing support to the patient. For instance, Alzheimer s patients often do not recognize their caregiver who may also be their spouse. Here are some burdens that caregivers have to deal with.

Anger- The sense of fury towards the patient can be strong after years of providing care. They may also be frustrated with the fact that the affected person is unable to perform simple everyday jobs, such as brushing their teeth or tying their shoelaces.
Anxiety- A sense of hopelessness regarding the future is common. It is also the fear of what new challenges the next day might bring.
Depression- Seeing their loved one s mental state deteriorating with each passing day can be difficult to handle and pushes some caregivers into depression.
With such continuous emotional and physical stress, caregivers often fall sick themselves. This is why it is necessary to maintain a bright outlook and remember that a dementia patient can only get well if they have the full support of the caregiver. In case you have a concern or query you can always consult an expert & get answers to your questions!

Treating Dementia - Things You Should Know!

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!

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.

Alzheimer's Disease & Depression - How They Are Related?

In recent times, the advancement of medical science has substantially contributed in comprehending the Alzheimer s disease. Unfortunately, the number of individuals suffering from the disease is expected to rise in the next ten years which pose a threat to the allocation of health care resources and public health. Alzheimer s disease is thought to be a complex disease which influences a person s behavior as well as cognition through numerous mechanisms.

Can surgery be deemed as a treatment for Alzheimer s disease?
The surgery is a multicenter clinical trial which is making a new direction in clinical research. It is devised to halt or slow down the problems caused by the disease which gradually erases a lifetime of memories in elderly patients. Though there is no cure for Alzheimer s disease, it has been found that low-voltage electric charges delivered right at the brain. Only the symptomatic therapies for Alzheimer s disease are provided which do not have any effect on the evolution of the disease. The standard medical treatments for Alzheimer s disease include cholinesterase inhibitors along with a partial N-methyl D-aspartate antagonist. In most cases of mild to moderate symptoms of this disease, a combination of treatments is used according to the clinical history, age and condition of the patient.

Mental activity supporting cognition
Many patients having normal cognition or mild impairment have a fear that they may develop AD. Many experts are of the opinion that mentally challenging activities including brain teasers and crossword puzzles can be helpful in reducing the risks in such patients. Clinical trials are under the way for determining whether or not these types of activities have any substantial effect on halting the progression of AD.

Treating AD in its moderate to the severe stage
Numerous studies have shown that blockade of NMDA receptors by memantine can be used safely in combination with ChEls. This combination has been shown to delay the institutionalization in patients with Alzheimer s disease.

Treating secondary symptoms
A variety of behavioral as well as pharmacologic interventions can help in overcoming the clinical manifestations of the disease. These include anxiety, psychotic behavior, depression and agitation among others. The effectiveness of this disease can range from modest to excellent. No particular agent or dose of it can be unanimously accepted to be the sole treatment option for the wide range of clinical issues. Moreover, in the recent time, the FDA has not accepted any psychotropic agent for treating AD.

Along with these treatment options, there are behavioral interventions that can range from patient-centred approaches to caregiver training for helping manage the cognitive and behavioral manifestations of Alzheimer s disease. Last but not the least, it is very crucial to point out the significance of treatment in the early stages of AD in order to cure it better.
