How many phases are there in Alzheimer's disease?

Alzheimer's disease is generally understood to progress through three distinct phases, which are often characterized by their symptoms and the increasing impact on daily functioning. In the early phase, individuals may experience mild memory loss, particularly related to recent events, as well as difficulties in finding the right words or following conversations. As the disease progresses into the second phase, cognitive decline becomes more pronounced, leading to significant memory loss and confusion about time and place. In the final phase, individuals typically experience severe cognitive impairment, losing the ability to communicate effectively and requiring more comprehensive care for daily activities.

Recognizing that there are three phases is essential for understanding the progression of the disease, which can aid caregivers and family members in managing care and expectations as the disease advances. The other options suggest either fewer or more phases than are widely recognized, which may overlook the complexities involved in the progression and symptoms of Alzheimer's disease.
