What is Alzheimer’s Disease?

Alzheimer’s disease is a progressive neurological illness in which the brain cells degenerate and become dead. It is a most common type of dementia disease in which the death of the brain cells causes steady loss of memory and cognitive deterioration. In fact Alzheimer’s disease in itself is the most common cause of dementia — a cluster of brain ailments that cause the loss of cognitive and communal skills. A neurodegenerative form of dementia, the disease begins moderately and gets sickening progressively. Since it is a progressive disease, it continues to hamper a person’s memory and other significant brain functions. The total brain size contracts with Alzheimer’s disease condition – the tissue has successively lesser nerve cells and connections.

Initially, someone with Alzheimer’s may see slight confusion or incomprehension and difficulty memorizing. Over a period of many months or years, person with the disease may notice to forget important or close people in their lives and undergo startling personality and behavioral changes.

In Current times Alzheimer’s disease medications and clinical management practices may improve symptoms. This can help people with Alzheimer’s disease improve mental and physical functionality and keep their independence alive for a little longer. Along with medical treatment and therapies, it is also significant to receive supportive and care services and call upon your support network as soon as possible.

In Alzheimer’s, there are minute ‘tangles’ and ‘plaques’ within and between the brain cells called- Neurons which are also known as Nerve cells in the brain. While they are unable to be viewed or tested in the living brain impacted by Alzheimer’s disease, autopsy/postmortem will always present microscopic incorporations in the nerve tissue, called ‘tangles’ and ‘plaques’ :

  • The tangles are found within the brain neurons – from a fragmentation of a protein, called tau.
  • Plaques originate in between the dying cells in the brain – from the production of a protein called beta-amyloid also known as “amyloid plaques”.

For an in-depth understanding of what goes on with the Alzheimer’s disease mechanism, succeeding from the normal brain to increasing dementia disorder, the Alzheimer’s Association Authority has created some illustrations that are as follows:-

  • The abnormal protein chunks, incorporations, inclusions in the brain tissue always remain with the disease, but there could be another suppressed process prevailing that is actually causing the Alzheimer’s disease – scientists are not confirmed yet.
  • This kind of alterations in brain nerves is also validated in other diseases, such as – depression, bipolar disorder, cardiac arrest and health researchers want to identify more than just that there are protein abnormalities – they also want to carry out how these symptoms develop so that a permanent prevention or cure might be determined.
  • Health Researchers are still not sure as to why the alterations that leads to Alzheimer’s disease takes place. Various different elements are thought to be involved. Risk factors for acquiring and advancing the condition include aging, a family history of Alzheimer’s disease, and holding certain genes.

 

Quick facts on Alzheimer’s disease

Here we have presented some key points, detail and supporting information about Alzheimer’s disease. This includes:-

  • Alzheimer’s disease is the most typical and common type of dementia.
  • The word “dementia” shows a loss of mental capability linked with steady expiration of brain cells.
  • There are on an approx a 5.3 million Americans of all age groups with Alzheimer’s disease. An estimated of 5.1 million people are age 65 and above, and about 200,000 people are below the age of 65.
  • In estimated of around every 67 seconds someone in the United States develops the disease.
  • It is one of the most common causes of increasing death rate in the US that is unable to be slowed, prevented, or cured permanently. 1 in 3 senior citizens passes away with Alzheimer’s or another type of dementia.
  • As the people of the US ages, Alzheimer’s is becoming a more persistent of death.
  • Almost 2/3rd of Americans with Alzheimer’s are women.
  • Alzheimer’s disease and other type of dementias cost the US $226 billion yearly.
  • Due to the psychological and physical toll of care giving, Alzheimer’s and other dementia caregivers had $9.7 billion in extra health care expenses of their own in the year 2015.

 

Early-onset Alzheimer’s disease

Hereditary is the major reason behind early-onset familial Alzheimer’s disease, which occurs generally between 30 to 60 years of ages and develops in those people who have it running in blood or have a family history of it. Inheritance from the Genetic mutation of the parents or family typically causes early onset of familial Alzheimer’s disease. Because of1 of 3 inherited genes, it is also called as young-onset, and it is rare – accounting for fewer than 5% of total Alzheimer’s cases.

The Alzheimer’s Association mentions in its early onset of Alzheimer’s disease information that the neurodegenerative illness can sometimes be “a lengthy and annoying process” to get this diagnosis confirmed since practitioners do not expect to determine Alzheimer’s in younger people and doctors will find for the other dementia causes first, for the younger age groups. Stress is another symptom attributed towards cause of Alzheimer’s as stated by some Healthcare professionals.

 

Recent developments in Early-onset Alzheimer’s disease

Understanding the other considerable causes and risk factors for early onset of Alzheimer’s disease is important as it will be helpful for a better medical management. It includes:-

  • Excessive exposure to environmental viruses or noxious substances
    A recent study has led scientific researchers to a significant discovery; an environmental virus present in some lakes and soils of the island may rise up the risk for Alzheimer’s dementia as well as for other neurodegenerative diseases. A Pacific Island of Guam situated in a territory of the US has been witnessed with such an environmental virus and villagers living in the close vicinity are affected by it.
  • Alzheimer’s brain plaques detected in people with head injuries
    The plaques found in the brains of middle-aged people (40-65 years of age) who have had brain injuries, as per a new study, documented in Neurology. These amyloid plaques in the brain match those found in Alzheimer’s dementia disease, but their spatial distribution varies.
  • Gum diseases may intensify cognitive decline for Alzheimer’s sufferers
    Gum diseases in itself is a displeasing condition, causing painful gums, bleeding, bad breath, tooth loss, cankers, ulcers and even sore gums. But people with Alzheimer’s dementia disease might experience worse, after a recent study depicts gum disease may heighten or pace up the psychical decline.
  • Greater risk of Alzheimer’s disease in people with rosacea
    People with rosacea seem to be a at a little close on to the edge to developing Alzheimer’s, and the disease in specific, compared with individuals without the common chronic inflammatory skin disorders.

Symptoms of Alzheimer’s disease

The information in this section closely associates to some of that sins, symptoms, and diagnosis because of the symptoms observed by patients, or folks closely connected to them, are exactly the same signals that healthcare experts look for during testing and diagnosis.

Symptoms for the illness can be diagnosed at any stage of Alzheimer’s dementia disease and the succession through the stages is evaluated after an introductory diagnosis, too, when the developing symptoms command how care is handled.

Without a doubt, the very characteristics of the Alzheimer’s dementia symptoms can be dubious for both the patient and the people around them, with varying levels of seriousness. For this matter, and because symptoms could indicate any of a number of diagnoses, it is always justifiable consulting a doctor.

For doctors to make a literal first diagnosis of Alzheimer’s dementia disease, they must first be confirmed themselves that there is dementia- directives dictate out what dementia comprises of. It includes behavioral and cognitive symptoms that depicts a downturn from former levels of “processing and performing” and intervene with the potential “to operate at work or at routine activities.

The cognitive downturn is in at least 2 of the 5 symptom projections listed below:-

  1. Sickened ability to grasp, assimilate and recollect new information, for instance:
    • Forgetting appointments, important persons, events and spellings
    • Be unable to lay one’s ands on or misplacing personal items of use.
    • Continually Repeating a same point or conversations
    • Lose track of a familiar route.”

     

  2. Deformity in to logical interpretation, judgment or difficult tasking:
    • Poor perception of safety risks
    • Incompetency in organizing monetary matters and calculations
    • Impaired decision-taking ability or delayed thought process.
    • Inability to plan step-by-step activities or a little complex task.

     

  3. Impaired vision (but not, for example, due to eye sight issues):
    • Problem in identifying faces, objects or to search objects in direct view
    • Incompetency to incorporate easy executions, or disoriented dressing to the body.”

     

  4. Distorted speech, reading and writing:
    • Problem finding the appropriate words and sentences while ordinary speaking or voicing opinion among a group of people.
    • hesitations and becoming introvert like that what had never been existing earlier
    • Ongoing errors in Talking, spelling, and writing.”

     

  5. Changes in behavior and personality:
    • Out-of-character mood swings, including anxiety; low-spirited, lack of morale, enthusiasm, initiative or involvement; isolated.
    • Loss of warmth, appreciation, communion and sympathy
    • Compulsive obsessive disorder or socially distasteful behavior.

    Once the severity and number of these projected symptoms witnesses’ dementia, the best interpretation is that they are because of Alzheimer’s dementia disease. It is given by:

    • A steady commencement “over months to years” rather than hours, days or weeks (the situation with some other disorders)
    • A notable sickening in an individual’s normal degree of cognition in specific areas.

    The most usual depiction featuring Alzheimer’s dementia is where symptoms of memory loss are the most pronounced, particularly in the area of learning, memorizing, and recalling new information. But the introductory depiction can also be one of chiefly language issues, in which case the main symptom is juggling to discover the right words.

    If visuospatial defaults are most noticeable, meanwhile, these would include the inability to view or recognize familiar objects and faces, to envision distinct elements of a scene at once (simultanagnosia), and a kind of trouble with reading text (alexia). Ultimately, the most prominent default in “implementing malfunction” would be to do with reasoning, problem-solving and analysis.

 

Conventional and Other Treatments Available

Alzheimer’s Treatment/Alzheimer’s Cure

There are effective medicines, therapies and support systems available for Alzheimer’s disease, that can help a sufferer relieve of some certain symptoms, slowing down the progression and let them lead a quality life maintaining a balanced cognitive condition.

There are several other kinds of support available to help people with Alzheimer’s dementia disorder live as freely as possible, such as incorporating changes in your family environment, in-house setting so it is simpler to roam around, comfortable doing tasks and remembering routine things.

Cognitive treatments such as psychological stimulation therapy may also be provided in order to help improvise your memory, language ability, problem solving skills and judgment.

  1. Drug therapy
    There are disease-altering drug options available for Alzheimer’s dementia disease that are helpful in reducing its symptoms and lead to boost quality of life. These are currently 2 types of drugs that are commonly used to treat cognitive symptoms of Alzheimer’s dementia disease:-

    • Cholinesterase inhibitors- These inhibitors function by actively amplifying the levels of a cell-to-cell transmission by offering a neurotransmitter (acetylcholine) that is exhausted and diminished in the brain by Alzheimer’s dementia disease. Cholinesterase drugs can alleviate neuropsychiatric symptoms, like violent behavior, agitation or isolation, as well. The improvement is satisfactory.
      Most Commonly recommended cholinesterase inhibitors drugs by expert doctors consists of alantamine, donepezil, galantamine and rivastigmine. There is however no fatal side effects of the cholinesterase inhibiters but some people may experience main side effects of these drugs which include loss of appetite, nausea, distorted sleep and diarrhea. In patients with cardiac conduction illness, major side effects may include a heart block or slowed down heart rate. There are 4 different kinds of drugs in cholinesterase class of inhibitor approved for symptomatic relief in the United States:-

      • Alantamine (brand name Reminyl)
      • Donepezil (brand name Aricept)
      • Rivastigmine (brand name Exelon)
      • Tacrine (brand name Cognex).

       

    • Memantine (Namenda) – This is a different type of drug, an NMDA receptor antagonist, may also be prescribed, singularly or in combination with a cholinesterase inhibitor drug. Memantinedrug functions in another brain cell transmission network and slacks off the progression of symptoms with mild to intensified Alzheimer’s. Memantinedrug is sometimes used in combination with a cholinesterase drug for better results and cognitive improvement. The main Side effects of Memantinedrug may include drowsiness, headache and muscle spasm.

    Occasionally some other medications like antidepressants or Anti-anxiety drugs are used to control the personality and behavioral modification symptoms linked with Alzheimer’s disease. However, these medications must only be used on a doctor’s prescription and with great caution, in particular for people with Alzheimer’s or other type of progressive neurodegenerative diseases. For instance, some common sleep drugs —eszopiclone (Lunesta), zolpidem (Ambien), and others — may increase the risk of loss of physical balance, trip over, and confusion.

    On the other hand, Anti-anxiety medications, — such as lorazepam (Ativan) and clonazepam (Klonopin) — increase the risk of vertigo, wooziness and confusion. It is highly recommended to consult with your GP before taking any such new medications under Alzheimer’s.

  2. Other therapy
    As with Alzheimer’s, neurodegenerative disease other types of dementia, a crucial part of treatment therapy for patients with these conditions typically comes from the care and support provided by care givers, healthcare workers, close family members to provide upgraded lifestyle, proper attention, and boost in cognitive health and confidence, which becomes more apparent as needs starts to increase overtime with declining independence for AD sufferers.
  3. Recent developments in treatment and prevention
    • Alzheimer’s disease treatment hint found in brain inflammation
      Up to date, scientists assumed that Alzheimer’s disease interrupted the immune system – but a recently conducted new study on mice adds to ascending witness that it could be due to inflammation in the brain that prompts Alzheimer’s dementia disease. It indicates obstructing a protein that governs the immune cells, could be a proficient trick to halt the brain-damaging disease.
    • Exercising and keep yourself moving to minimize the severity of Alzheimer’s
      It is recently discovered that any type of exercise performed by the AD patient can improve blood circulation and oxygen supply to the brain and thus leading to improved brain operations and halve the risk of developing Alzheimer’s disease.
    • Intake of Blueberries to fight against Alzheimer’s disease
      Blueberriesare not a new thing in the market. The popular fruit not only enhances taste to the meals when added but also play a key role in prevention of prompting the Alzheimer’s disease. You can simply add it to your salads, cereals, shakes and desserts or just eat as a sweet candy treat in their own self. Blueberries are also called as a “superfood,” by some as they are known to consist of a huge variety of nutrients that offer protection against chronic ailments such as heart disease, brain disorders and cancer. And many healthcare researchers derived that they may have a crucial part to play to fight against Alzheimer’s dementia disease.
    • implantable capsule produced validation for prevention for Alzheimer’s disease
      There is presently different ways to prevent, slow down or cure Alzheimer’s disease, but people respond positively and negatively or neutrally to these different treatments; however a recent research details the making of an implantable capsule that health researchers suggest could permanently stop the illness in its tracks.
    • Lost memories regained in mice with early onset of Alzheimer’s dementia disease
      With the recent developments in medical management for Alzheimer’s, it could be possible to permanently retrieve lost memories for those with early Alzheimer’s, as per a new study printed in Nature, in which researchers disclosed how they succeeded with the same that in mice with early symptoms of theAlzheimer’s dementia disease.

 

Can Alzheimer’s disease be prevented?

There is a buzz all over that Alzheimer’s is a no preventable disease, however if the exact cause of Alzheimer’s disease is clear, there is some known way to decelerate or prevent the condition. The things that you can do to reduce the risk or delay the onset of Alzheimer’s or other types of dementia includes:

  • Eat nutritious and have a well balanced diet
  • Maintaining a healthy weight and body mass index
  • Do exercises and yoga to stay mentally active, calm and fit.
  • Limit yourself from playing contact sports or wear helmetsto reduce the Risk of Head Trauma, rates of head injuries
  • Cutting down or giving up on regular alcohol
  • Stop smoking or weed

These preventive measures have other health benefits too, such as reducing your risk of cardiovascular disease and boosting your overall mental and physical health.

 

Who is affected?

Alzheimer’s dementia disease is most prevalent in people of more than the age of 65 years, and relatively affects women more than men.

The risk of Alzheimer’s and other types of neurodegenerative diseases usually increases with age, affecting an approximately of one in every fourteen people above the age of 65 and one in six people above the age of 80. However, an estimated of one in every twenty cases of Alzheimer’s dementia disease affects people aged between 40 – 65 years of age.
