What hallmark symptom is associated with Alzheimer’s disease?

Alzheimer's disease is primarily characterized by cognitive decline, particularly in memory and reasoning abilities. A hallmark symptom of the disease is the change in personality and the emergence of bizarre thought patterns. As the disease progresses, individuals may experience confusion, mood swings, and a shift in their usual behavior or outlook on life. This can manifest as increased anxiety, depression, and sometimes aggression, which can alter their interactions with others and affect their overall personality.

Understanding this symptom is vital for caregivers and healthcare providers, as it helps guide therapy and support measures. While other symptoms like coordination issues or difficulties with fine print reading may occur due to cognitive decline, they are not as closely linked to the defining characteristics of Alzheimer’s. The change in personality and unusual thought processes stand out as a core component of the disease's psychological and emotional impact on individuals.
