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

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!

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?

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?

Aging comes with many health problems including mild hearing loss. Usually, this mild hearing loss does not come alone. According to medical studies, adults, particularly males with hearing loss, mild or severe, are at a higher risk of developing Dementia and Alzheimer s disease. The risk increases as the hearing loss worsen. People with mild hearing loss are at twice the risk of developing dementia compared to people with normal hearing.

Dementia is a group of symptoms and diseases that affects the thinking, memory and social abilities that interfere with the daily functioning of an individual. However, memory loss alone does not mean that one has Dementia. Out of the many causes, Alzheimer s disease is usually the cause of Dementia. Alzheimer s disease is a progressive disease that affects the brain cells to degenerate and dies, destroying memory and other mental functions. 

How Hearing Loss Causes Alzheimer s?

According to medical studies, hearing loss causes several brain changes which increase the risk of developing Dementia. Hearing loss can lead to brain shrinkage, the process in which the section of the brain responsible for hearing becomes inactive. This condition leads to loss of tissues and alterations in the brain structure, developing as the first connection between hearing loss and Alzheimer s. Studies show that the brain of people shrinks more quickly who have hearing loss as compared to the brain of an individual with normal hearing. 

The second link created with an overwhelmed or overloaded brain. In hearing loss, the brain works overtime in understanding what others are saying. When the brain strains too much only for hearing every time and every day, it exhausts an individual s mental energy and snatches the brainpower required for other important mental functions, such as thinking, remembering and acting. This can further lead to Dementia, Alzheimer s and other mental disorders. 

Hearing Aids to prevent Dementia and Alzheimer s

According to various studies, hearing aids are not only helpful in improving one s hearing but they can also preserve an individual s mental and emotional health. Early diagnosis and treatment of a possible hearing loss help reduce risks later in life.

At times, the symptoms of undiagnosed hearing loss are mistaken with the symptoms of Alzheimer s. Hearing impairment makes it challenging for an individual to listen and respond to verbal signs. It increases the feeling of confusion, paranoia, and isolation. 

Hearing aids can relieve the symptoms of Alzheimer s. According to a study hearing aids slow down the rate of memory loss and improve an individual s quality of life.

Takeaway

Adults, especially males with hearing loss have a greater tendency of developing Dementia and Alzheimer s. Hearing loss causes brain to overwork leading to the loss of important mental functions. Hearing impairment can worsen the symptoms of Dementia and Alzheimer s. 

Hearing aids do help in improving the condition and symptoms of Alzheimer s and improve one s quality of life. A timely diagnosis can make a big difference.

Dementia And Alzheimer's Disease In Elderly - Could Hearing Loss A Reason?

Parkinson s disease adversely affects the way you move, as it is a neurodegenerative disorder. This happens when there are problems with certain nerve cells in the brain. These nerve cells produce an important chemical called Dopamine, which in turn sends signals to the region of our brain that takes care of the movement. This chemical help muscles to function smoothly and allow in carrying out one s daily activities. When somebody is suffering from Parkinson s disease, the nerve cells break down, thus hampering movements of limbs.

What Causes This Disease?

Over the years, a lot of research has taken place to find out the exact reasons due to which people get affected by Parkinson s disease but till now neither scientists nor doctors have been able to come up with any solution. They are thinking on the lines of aging or hAarmful chemicals in the environment, to be possible causes for this neurological problem. Sometimes researchers even feel that this could be a hereditary problem but there is no concrete evidence to substantiate this statement.

Symptoms Of Parkinson s

As discussed earlier, Parkinson s occur in aged individuals, when nerve cells break down, when the chemical called Dopamine is no longer able to send signals to the brain. You can easily recognize Parkinson s disease in any of your family members, if you come across certain symptoms, which are generally four of them:

Trembling or shaking of limbs and these tremors can affect different body parts like, hands, arms and legs.
Muscles become stiff, due to which it becomes tough for the affected individuals to move their limbs freely.
Due to stiffness of muscles, movement becomes slow and thus each and every activity of theirs takes much more time than usual.
People are unable to keep their balance and walk freely without any hindrance.
Generally, tremor is the first thing you would notice in a person and thus instantly get to know that the person might be suffering from Parkinson s.
Problems of constipation or facing difficult in swallowing tend to happen as the disease goes on to affect all the muscles in one s body. 
During the latter stages, someone who has Parkinson s, might well have a blank expression to the face with problems being faced while trying to speak and other related issues. The symptoms of this disease usually start for people aged between 50 and 60 but at times, it can even crop up at an earlier stage.
Preventive Measures And Treatment

Let s take a look at how you can prevent yourself from getting crippled by Parkinson s Disease.

Unfortunately, as the disease is mostly age related, so after attaining the age of 60, if not from 50, there would be very few individuals who would not be the victims of Parkinson s.

Research has revealed that having less of dairy and red meat and consuming more of fruits, vegetables and high-fibre foods, thus maintaining a healthy diet, can protect people from the dreaded disease.
