Alzheimer s disease is a neurological, irreversible, progressive brain disorder. It is a chronic neurodegenerative dementia that causes the death of brain cells, causing memory loss and cognitive decline. It affects a person s thinking and behavior. The symptoms develop slowly and get worse as time passes.

Causes:
As it is a kind of dementia, Alzheimer s is caused by the death of brain cells. Over a course of time, brain cells die progressively and at the end, the tissue is left with fewer nerve cells and connections. As a result, the total brain size shrinks. Tiny inclusions called plaques and tangles can be seen in the postmortem. These cannot be seen or tested in a living Alzheimer s affected brain. These plaques are given the name  amyloid plaques  because they are found among the dying cells of the brain when a protein called beta-amyloid builds. The tangles stay in the neurons; they are formed from a protein called tau.

There are several reasons behind all this, some of which are listed below-

Anti-anxiety medications
Hitting on the head too many times
Regularly sleep-deprived
Loneliness
Diabetes in the brain
Old age
Genetic line
Down s syndrome
Cardiovascular diseases
Symptoms:
Alzheimer s disease damages the brain, so the clinical signs and symptoms begin to show very early. The symptoms are-

Memory loss
Agitation and mood swings
Poor judgment
The trouble with money calculations
Difficulty doing familiar tasks
Trouble in planning or solving a problem
Confusion with time and place
Difficulty in communicating
Loss of motivation
Inappropriate behavior
Aggressive personality
Childlike behavior
Preventing Alzheimer s disease:
Alzheimer s disease ultimately results in death. Even if there are treatments, they cannot fully cure it. So it s better to try to prevent it before it happens. Ways to prevent Alzheimer s disease are-

Eating more fruits and vegetables.
Eating berries every day.
Increasing omega-3 fatty acids.
Taking folic acid supplements.
Drinking grape juice or red wine with evening meal.
Doing the Mediterranean style diet.
Controlling the blood pressure.
Having strong social support.
Treatment of Alzheimer s disease:

Treatment of Alzheimer s disease is a long time process.
First of all, doctors perform a physical exam to check the overall neurological health. By this, they check muscle strength, reflexes, walking ability, sense of sight and hearing, coordination and balance.
Then comes the blood test to find the cause of confusion and memory loss by checking the thyroid disorder and vitamin deficiency.
Then they perform the neuropsychological test and check the mental status.
Then there are other tests, like MRI, CT, and PET.
After all this, drugs are given and a safe and supportive environment is created with proper exercise and nutrition.
Alzheimer s disease is undoubtedly the worst kind of disease. Hence, it is highly recommended to contact a doctor as soon as any symptom is noticed.

All About Alzheimer's Disease!

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?

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.

Parkinson's Disease - Understanding The Motor & Non-motor Symptoms!

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.
A 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 a 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 a 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 the Parkinson s disease.

Parkinson's Disease - What Are The Risk Factors?

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 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.
