13Observing
People with mild Alzheimer’s disease tend to spend more time of the day observing everything around them. When someone disturbs, they would become agitated and annoyed. This sign makes them easily get lost when walking around the neighborhood, even in familiar places. It can also occur at night and affect their sleep patterns, thus leading to insomnia. In most cases, it is quite easy to notice this sign as it is quite rare and does not occur in many health issues. Thus, visit your doctor as soon as it happens. [13]
