Alzheimer’s disease and its treatment



Healthcare improvements have contributed immensely to people living longer and healthier lives. However, there are certain noncommunicable diseases that have affected people in one way or the other. One such disease is Alzheimer -- a brain disorder that causes dementia; and characterized by a gradual decline in cognitive function. People living with Alzheimer’s disease, suffer from memory loss, thinking and behavioral problems.

Factors Responsible for the disease

Scientists have found that the main cause of Alzheimer’s disease is the complex series of events that take place inside the brain. The factors involved in causing the disease include genetic, lifestyle and environmental factors. Since people living in different areas differ in their genetic make-up and lifestyle, any of these factors may increase or decrease the risk of developing the disease.

Causes of the disease

One of the mysteries associated with Alzheimer’s disease is that it affects older adults. Age-related changes cause changes in the brain cells and may eventually harm neurons to cause the disease. Age-related changes may involve shrinking of some parts of the brain, called atrophy, production of free radicals and mitochondrial dysfunction, to name a few.

Symptoms of the disease

According to WHO (World Health Organization), people with dementia syndrome can be grouped into three different groups: Early stage, Middle Stage and Late stage. These stages have been categorized depending upon the symptoms of the disease.
Early Stage: This stage is often overlooked – family members and close relatives consider it as an old age problem. However, when this stage begins, a person becomes forgetful, lose track of the time, have difficulty making decisions; may show mood changes such as depression or anxiety.
Middle Stage: Once the disease progresses, symptoms become more clearer. For instance, a person with Alzheimer’s disease fails to remember recent events, have difficulty in communication, needs personal care, etc.

Late Stage: During this stage, a person becomes totally dependent on others. One fails to understand what is happening around, unable to recognize friends and familiar objects, behavior may escalate such as aggression towards carer, etc.

Treatment of Alzheimer’s disease

There is no cure for Alzheimer at this point of time. However, the treatment and research give emphasis on several other aspects such as helping people in maintaining mental function, delaying the symptoms of the disease or managing behavioral symptoms. One of the main aspects of treatment is the support of family members. People suffering from the disease need more care and affection for their family members, friends and close relatives.
