Alzheimer ’ s disease is common in older people. It is a progressive neurologic disorder resulting in the shrinking and death of brain cells. This condition is a common cause of dementia, characterized by reduced behavioral, social, and thinking skills, affecting independent functioning in the affected individual.

An estimated 5.8 million persons in the United States aged 65 and above experience Alzheimer ’ s disease, and approximately 80% of this population are over 75 years. About 60% – 70% of people living with dementia worldwide have Alzheimer ’ s disease.

Common signs of Alzheimer ’ s in the early stages include forgetting conversations and recent events. Over time, the condition can cause severe memory im pairment and the inability to undertake daily activities.

Medications to slow the progression of symptoms or improve them temporarily are available. In some cases, the treatment can help people with Alzheimer ‘s maintain independence and function properly.

However, no available treatment can cure Alzheimer ’ s disease or stop the progress of the condition in the brain. Advanced stages of the condition results in complications such as malnutrition, infection, and dehydration, which can cause death.


In the early stages, a person developing Alzheimer ’ s disease may have difficulty organizing thoughts and remembering events . Still, a close person or family member will likely notice as the symptoms worsen.
