Understanding The Alzheimer’s Continuum
As our understanding of Alzheimer's disease has deepened, researchers have identified the progression symptoms into 3 key phases, collectively known as the Alzheimer's Disease Continuum. The three key phases that make up the continuum are Cognitively Normal, Mild Cognitive Impairment (MCI), and Dementia.
In this blog post, we will explore each of these three phases and how the disease progresses within the individual.
Phase 1: Cognitively Normal or Preclinical
The first phase of Alzheimer's disease is the cognitively normal stage - this means that individuals in this stage exhibit no outward signs of decline in memory, language, orientation, and problem-solving skills. While there are no outward signs of the disease, recent research has proven that changes in the brain's structure and function can occur years before any noticeable symptoms of Alzheimer's disease manifest in this cognitively normal or "preclinical" stage.
Current research is focused on determining the biological markers present that indicate risk of developing Alzheimer's, as our best opportunity is to stop the progression of the disease before it starts.
Phase 2: Mild Cognitive Impairment
Mild cognitive impairment (MCI) is the second phase of Alzheimer's disease. It is characterized by a decline in cognitive abilities that exceeds what is considered normal for a person's age and educational level. Individuals with MCI may experience memory loss or problems with language, attention, and decision-making. MCI is often a precursor to dementia, although not all individuals with MCI will progress to dementia.
Researchers are focused on slowing the disease's progression during the MCI phase in order to delay or prevent the onset of dementia.
Phase 3: Dementia
Dementia is the most severe phase of Alzheimer's disease, characterized by significant memory loss, disorientation, and other cognitive impairments that negatively impact daily life. Persons with dementia typically struggle with routine tasks such as dressing, grooming, and preparing meals. It can be very challenging to manage and care for individuals with dementia, and they may require a team of healthcare professionals to help support both them and their caregivers.
There are currently no known cures for Alzheimer's disease or dementia. However, ongoing research continues to find ways to alleviate symptoms and improve the quality of life of those diagnosed with dementia.
How Can You Participate?
Alzheimer's disease is a complex and challenging condition that affects millions of people worldwide. Understanding the three key phases of the disease is a crucial first step in identifying and managing the early symptoms of Alzheimer's disease.
Remember, there are no definitive cures for Alzheimer's disease and dementia, but early detection and intervention can significantly improve the quality of life for those living with dementia and their loved ones. By educating oneself about the disease and supporting those affected by it, we can create a more informed and compassionate society that is better equipped to help those affected by Alzheimer's disease. Those interested can consult their primary healthcare providers, reach out to ATRI, or search for ongoing trials in their area.
