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?

One of the common ailments in the elderly people is the Parkinson s. A progressive disorder, when left untreated, results in worsening of the symptoms. Hence, it is essential to understand the treatment options available to manage the condition effectively. You may be suggested surgical therapies if medication is not effective enough to treat the symptoms.

Surgical treatment options can be beneficial for patients who are suffering from symptoms, but they do not help with treating the disease. In the past, surgical methods like Thalamotomy and Pallidotomy were used to destroy brain cells that contributed to the symptoms. While these methods are still used, they are very rare and situational.

Deep Brain Stimulation (DBS), an FDA-approved procedure, has become much more popular as it is much safer and does not involve invasive surgery. Instead of destroying brain cells like traditional methods, DBS involves sending electric pulses to the affected brain cells to reduce the symptoms. It is not a treatment procedure, but a means of bringing down the severity of Parkinson s to allow better and more comfortable treatment.

Deep Brain Simulation   Who are the right candidates?
Deep Brain Simulation is commonly used for Parkinson  s disease, but it is not recommended for everyone. It is a preferred method of treatment for people who have had Parkinson s for at least four years but have complications which include long periods of time where medications do not work, or symptoms return, uncontrolled and involuntary movements or the freezing/stiffness in the body.

Deep Brain Simulation is not recommended for those who have Dementia as it can lead to memory problems. The general rule of thumb that neurosurgeons follow is that Deep Brain Simulation can help with symptoms that do not get better with medication. DBS can help reduce medication requirements for patients as well as reduce the side effects that may occur due to medication.

Disorder specialists and neurosurgeons can conduct tests to determine if DBS is going to be effective for a patient before going ahead with such a procedure. An extensive assessment is necessary to understand the symptoms, the effect of Parkinson's drugs and also brain imaging is done. All of the expected benefits are then evaluated for the patients, and if the procedure can help alleviate the symptoms, DBS is given a green signal by neurosurgeons and patients can undergo the procedure.

How Does Deep Brain Simulation Work?
Deep Brain Simulation is a very complex procedure. Brain cells communicate with the rest of the body through electric signal, and these become irregular and do not work properly when affected by Parkinson's. DBS smoothens the functioning of these brain cells and reduces symptoms through electric pulses through the implantation of a medical device known as neurostimulator which is also referred as brain pacemaker.

But, as with any treatment procedure, DBS has potential risks and side effects, hence discuss with neurosurgeon thoroughly to access the suitability.

Adopting Deep Brain Stimulation For Parkinson's disease

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.

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

Neurology is the branch of science and medicine dealing with the central and peripheral nervous system. The nervous system is made of the brain and spinal cord. The disorders, illness or injuries of the nervous system can become problematic for people suffering from them. One of the worst diseases of the nervous system is Parkinson s disease.

It is a progressive disorder affecting the central nervous system that leads to slowing down of movement and slurring of speech over a period of time. It is a condition where the nerve cells in the brain producing dopamine (a neurotransmitter) are affected.

Some of the early signs of Parkinson s include:

Tremor: If you have noticed a slight shaking of your hands or limbs, then Parkinson s might be the cause. The trembling can range from mild to severe as the disease progresses. The back-and-forth rubbing of your thumb and forefinger is known as pill-rolling tremor. One of the most prominent signs is your hand shaking even when it is rested.
Bradykinesia (slow movement): As the disease progresses, you may find it difficult to move your hands or legs or going from one place to another. Even making the smallest movement will require an increased effort on your part.
Rigid Muscles: The muscles in your body can become stiff causing you pain and making it difficult to perform physical activities.
Masked Face: Your face may experience spasms or become stiff periodically. It can also lead to complete paralysis on one side of the face.
Stooping or improper balance: Having Parkinson s disease can make your body posture imbalanced resulting in stooping or hunching over.
Decreased Automatic Movements: You may experience difficulty in smiling, blinking or swinging your arms while walking.
Alteration in voice or speaking: Your voice can become soft or you may slur while talking. You can also experience a monotonous voice.
Writing may become small: You can experience changes in your handwriting as it becomes small and crowded.
Loss of Smell: The smell of food sitting right in front of you may not register in your olfactory resulting in loss of appetite.
Constipation: Having Parkinson s disease can lead to patients experiencing irritable bowel syndrome.
Have Trouble Sleeping: It might be difficult to fall asleep for people suffering from Parkinson s. Also, there are sudden movements during the sleeping process.
Dizziness: People suffering from Parkinson s may faint from time to time.
These were some of the symptoms and signs by which you can tell whether a person has Parkinson s or not. However, as of now it is not curable and can only be treated with medicines. But, early detection can definitely help in preventing it from affecting the whole body.
