Mild dementia, especially in its early stages, often goes unnoticed by family members. The initial symptoms generally include being particularly forgetful. This particularly affects short-term memory; for example, a person might repeat what was just said or be repeatedly clumsy in daily tasks, sometimes losing keys or forgetting to turn off the stove while cooking. This might seem like a lack of concentration, but in reality, it is due to forgetfulness. Emotionally, individuals who were once lively might become indifferent or detached, sometimes showing signs of excitement or agitation. Behaviorally, there can be changes, such as previously generous individuals becoming stingy. Interests and hobbies that were once loved may no longer hold appeal, and individuals may become lethargic and less concerned with cleanliness and personal appearance.
