What stage of Alzheimer's disease is characterized by severe cognitive decline and loss of ability to carry on conversations?

The advanced stage of Alzheimer's disease is marked by severe cognitive decline, wherein individuals often lose the ability to engage in meaningful conversation and may have significant difficulties with communication overall. At this stage, patients typically require substantial assistance with daily living activities and may not recognize familiar people or surroundings. This deterioration in cognitive function extends to memory, problem-solving, and even aspects of personal care, emphasizing the profound impact of the disease on individuals and their families. Understanding this distinction helps highlight the needs of patients and informs caregivers and healthcare providers about the level of support necessary during this phase of the disease.
