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

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

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!

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.

Parkinson's Disease - Are You Aware Of These Signs?

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?

What is Parkinson s disease?
Parkinson s disease is a progressive and degenerative disorder of the Central Nervous System that mostly affects older people. It is a chronic disease and the symptoms develop over a period of time. The characteristic symptoms of Parkinson s are rigidity, shaking, bradykinesia (slowness in movement) and shuffled gait. Anxiety and depression also seem to be common in advanced stages of Parkinson s disease. In addition to the motor symptoms, the cognitive function of the brain is also compromised.

Degeneration of the nerve cells in the substantia nigra of the brain results in the reduction in production of dopamine which is a neurotransmitter in the brain. Neurotransmitters relay impulses from one nerve to the other. This is what is mainly responsible for the motor symptoms in Parkinson s. Although, Parkinson s is not a curable disease, it can be controlled and the progress of the disease can be kept in check with certain medications.

What causes Parkinson s disease?
The cause of Parkinson s is mostly idiopathic, i.e. the cause is unknown and is not specific. However, there have been cases which show that it can be attributed to factors such as genetic and environmental factors.
What are the symptoms of Parkinson s?

The symptoms of Parkinson s can be classified as Motor symptoms and Non-motor symptoms:

Motor Symptoms 

Bradykinesia: Slow movement
Tremor of limbs
Rigidity or stiffness of trunk and limbs
Impaired balance and difficulty in coordination or postural instability
Non-motor Symptoms 

Depression
Anxiety and fear
Loss of energy and fatigue
Constipation
Excessive salivation
Weight gain or weight loss
Cognitive problems such as difficulty in remembering, confusion, dementia
Parkinson s disease is not curable, but when detected early, medicines are prescribed to give symptomatic relief. Dopamine substitutes are prescribed to the patient to relieve the motor symptoms.
