In some countries, it is observed the whole month. Alzheimer’s is a progressive brain disorder that slowly destroys memory and thinking skills etc. In older adults, it is the most common cause of dementia.

Do you know that Alzheimer's is the most common cause of Dementia? According to some researchers, this disorder may rank third just behind heart disease and cancer, as a cause of death for older people. Most people with the disease are diagnosed after age 65. It is said that Alzheimer's disease accounts for 60 percent to 80 percent of dementia cases.

Therefore, we can say that Alzheimer's is a neurodegenerative and progressive disease that slowly destroys memory and other functions related to memory. It happens when plagues containing beta-amyloid form in the brain.

A person suffering from this disease is not able to think properly and the ability to carry out the simplest tasks destroys. With time, symptoms of Alzheimer’s become worsen; it becomes difficult for a person to remember recent events, to reason, and even to recognize people they know.

 Facts about Alzheimer’s disease.

1. Alzheimer's disease is named after Dr. Alois Alzheimer. He had noticed some changes in the brain tissue of a woman who had died of an unusual mental illness. It also occurs with other diseases.

2. According to a Ph.D. faculty Timothy Hohman at Vanderbilt University's Memory and Alzheimer's Center in Nashville Tennessee says that people who develop Alzheimer's disease have cardiovascular disease as well.

3. Alzheimer's disease is not just memory loss in fact decreasing memory is a major symptom of the disease. It is also caused by the build-up of proteins known as tangles or plaques within the brain and is also known as the third type of diabetes.

4. Due to this Alzheimer's disease brain cells decay and affect different kinds of cognitive functions like memory loss, language problems, and unpredictable behaviour.

5. The greatest risk factor for Alzheimer's disease is increasing age. It is not a part of normal aging, but your risk increases greatly after you reach 65. Sometimes symptoms may occur at the age of 30s or so because of rare genetic changes in the people i.e. genes are beyond our control and inherited a version of the apolipoprotein gene known as ApoE (one of three forms of a gene) and so is the beginning of early-onset Alzheimer's.

6. Alzheimer’s is an incurable disease as the death of brain cells cannot be reversed. By reducing the risk of heart disease you can lower the risk of this disease. Important factors that to be controlled are high blood pressure, high blood cholesterol, excess weight, and diabetes.

9. Do you know a person suffering from Alzheimer's disease can survive 3 or 4 years if the person is older than 80 when diagnosed and if the person is younger than 10 or more years.

10. Women have a higher risk of having Alzheimer’s disease than men. According to the US Department of Health and Human Services nearly twice as many women have Alzheimer’s disease as men. It worsens more quickly in women than it does in men. Brain shrinkage tends to be more severe in women than in men.

Therefore, we can say that Alzheimer's disease is a neurological disorder in which cells of the brain died which leads to loss of memory, a problem with words in speaking or writing, poor judgement, changes in mood and personality, confusion with time or place, etc. At the first stage, these symptoms are mild but they become more severe with time.
