A person may show sudden or intense shifts in mood, increased irritability, fearfulness, or suspiciousness. They may react strongly to minor situations or become frustrated as they lose independence with everyday tasks.

Frequent forgetfulness, especially of recent events, is common. People may repeat themselves often or rely heavily on reminders such as notes or calendars.

Individuals may have difficulty making safe or reasonable choices. This can include poor financial decisions, reduced attention to personal hygiene, or falling for obvious scams.

Objects may be placed in unusual locations — for example, keys in the bathroom or food items in the wrong cupboards — and the person may be unable to retrace their steps to find them.

A person may struggle to start or follow conversations. They might forget common words or substitute general terms like “thing,” leading to unclear communication.

Tasks that were once routine — such as paying bills, cooking familiar meals, or learning new skills — may become challenging. Misunderstanding instructions can lead to frustration or anger.

Daily activities like shopping, driving, cooking, or managing household chores may become harder over time. As these challenges increase, individuals may rely more on others for support.

A person may experience changes in balance, judge distances inaccurately, or trip more often. Spilling or dropping objects can also become more frequent.

People may become confused about dates, days of the week, or upcoming events. They may appear disoriented or unsure of where they are.
