Overview

Alzheimer’s is a progressive, degenerative brain disease that slowly destroys memory and thinking skills.

The disease starts with short-term memory loss and gets more serious over time. It eventually leads to the inability to carry out daily tasks.

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by a steady decline of cognitive function in the form of dementia, which typically begins after age 60 and becomes more common with advancing age. The first changes in cognition are usually at the level of short-term memory, but as AD progresses, other cognitive functions are also impaired including learning new information, disorientation in time and place, loss of abstract thinking ability (such as math skills), disturbance of language and motor skills (dementia), and decreased judgment due to long term exposure.

Alzheimer’s Disease is a neurodegenerative disease and the most common form of dementia. It is a progressive brain disorder that slowly destroys the person’s mental abilities, including memory. The disease begins with mild forgetfulness that slowly gets worse over time, eventually leading to complete loss of memory and inability to think.

In order for people who are facing Alzheimer’s Disease be properly cared for, there are a few things we can do.

First, it is important for family and friends to be educated about Alzheimer’s Disease. So they know how to react when confronted with it.

Secondly, there are many organizations that offer support groups and resources where those who are living with Alzheimer’s can go to find support and information about how best to live their lives during this difficult time in their lives.

Here Are the Two Types of Alzheimer’s Disease:

Early Onset: In this type of Alzheimer’s Disease, the symptoms first appear before age 60, and it often tends to progress quite rapidly. Several genes have been identified in connection with Early Onset Alzheimer’s, so it is also possible that it can be hereditary.

Late Onset: This is the most common form of Alzheimer’s Disease. It develops in people over the age of 60. In this type of Alzheimer’s the role of genes is not as clear.

Symptoms of Alzheimer’s Disease

Alzheimer’s disease is a type of dementia caused by a build-up of protein in the brain. There are 3 stages in the development of the disease and patients usually progress to more severe stages over time.

The first stage is mild cognitive impairment, which lasts for one to two years. The second stage is the beginning of Alzheimer’s disease, which lasts for 1-3 years. The third stage includes advanced Alzheimer’s disease and usually progresses after three years. Patients in this stage show moderate or severe cognitive impairment and exhibit symptoms such as losing memories, forgetting how to do things they normally would know how to do, being unable to follow a conversation, and becoming disoriented during day-to-day activities.

As with any other illness, there are ways to prevent.

Alzheimer’s disease is a progressive neurological disorder that slowly destroys and robs the individual of their abilities to think, remember and care for themselves. It is characterized by memory loss, impairment of language skills, changes in personality and problems with executing day-to-day tasks.

The disease can be broken down into three stages:

  • stage one includes memory loss and confusion.
  • stage two includes more significant cognitive problems.
  • stage three includes weight loss, disorientation and other physical ailments.

In the early stages of Alzheimer’s disease, some people may not realize they have it because many symptoms are also present in people who have other cognitive diseases or are aging normally. The only way to know for sure is to go to a doctor or neurologist for an examination.

Causes of Alzheimer’s disease

Alzheimer’s disease or AD is a type of dementia that is caused by the brain becoming damaged.

It affects memory, thinking, and behavior. It is a progressive disease which means it gets worse over time and eventually leads to death. AD can happen in anyone at any age but it is most common in people over 65 years old. Alzheimer’s disease causes many serious problems for the patient and their family members.

Since it gradually damages the brain, there are no cures for Alzheimer’s Disease. However, there are treatments available to slow down its progression.

Alzheimer’s disease is the most common form of dementia, and it is caused by changes in the brain that affect memory, thinking, and behavior. Alzheimer’s disease can be diagnosed by various methods including a physical exam and mental status testing.

In Alzheimer’s Disease, damage to nerve cells (neurons) causes progressive deterioration in these functions: – Memory, Language, Judgment, Orientation and Abstract thinking.

Stages of Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia and it is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. It starts slowly and gets worse over time.

The stages of Alzheimer’s are early, middle, and late stages.

The early stage is often called “mild cognitive impairment” or MCI. Early stage Alzheimer’s doesn’t have a major impact on a person’s day-to-day life and they may not even realize they have it.

The middle stage usually starts with a more noticeable change in mental function such as forgetting important details or losing track of time.

In the late stage, the person has severe problems with daily functioning such as staying awake long enough to eat or get dressed each day.

Latest Treatment for Alzheimer’s Disease

Since Alzheimer’s disease is commonly a slow process, the disease affects people differently and therefore individuals respond to different treatments uniquely. Currently, there is no drug or treatment program that stops the progression of Alzheimer’s disease. Here, are the some treatments for Alzheimer’s Disease.

Aricept (donepezil)

Orally, this drug is an irreversible inhibitor of the enzyme acetylcholinesterase. It is used to treat symptoms in people with Alzheimer’s disease. Our brains often produce acetylcholine, a chemical thought to be essential for learning and memory. People with Alzheimer’s disease have low levels of brain acetylcholine levels. A ricept works by reducing the activity of acetylcholinesterase, an enzyme whose function is to break down acetylcholine. It is believed that by reducing the degradation of acetylcholine, it will lead to an increase in the level of acetylcholine in the brain.

Cognex (tacrine)

Given orally, this is another medication that inhibits the enzyme acetylcholinesterase. Tacrine will not cure Alzheimer’s disease, and it will not stop the disease from getting worse. However, tacrine can improve thinking ability in some patients with Alzheimer’s disease.

Exelon (rivastigmine)

Another cholinesterase inhibitor given orally. This medication is used to treat loss of memory and thinking ability associated with Alzheimer’s Disease.

Razadyne (galantamine)

This medication was formerly known as Reminyl. It was changed to razadyne on July 1st 2005. Razadyne is a competitive acetylcholinesterase inhibitor. It has been shown to treat some of the symptoms of Alzheimer’s disease successfully.

Namenda (memantine)

Approved by the FDA in October, 2003, the drug is given orally, and acts differently on acetylcholinesterase inhibitors. Glutamate is a major neurotransmitter for pleasure in the brain. It was thought that too much glutamate in the brain could cause cell damage. Namenda works by blocking the effects of glutamate.

Antioxidants

Clinical studies have shown that vitamin E slows the progression of Alzheimer’s disease for nearly seven months. Clinical trials are currently being conducted in order to determine whether or not vitamin E slows the progression of Alzheimer’s disease.

Other clinical trials are currently underway to determine whether vitamin E and selenium supplements may help slow down or prevent the symptoms of this disease.
