Subtle short-term memory changes
Trouble with memory can be an early symptom of dementia. The changes are often subtle and tend to involve short-term memory. An older person may be able to remember events that took place years ago but not what they had for breakfast.
Other symptoms of changes in short-term memory include forgetting where they left an item, struggling to remember why they entered a particular room, or forgetting what they were supposed to do on any given day.
Difficulty finding the right words
Another early symptom of dementia is struggling to communicate thoughts. A person with dementia may have difficulty explaining something or finding the right words to express themselves. Having a conversation with a person who has dementia can be difficult, and it may take longer than usual to conclude.
Changes in mood
A change in mood is also common with dementia. If you have dementia, it isn’t always easy to recognize this in yourself, but you may notice this change in someone else. Depression, for instance, is typical of early dementia.
Along with mood changes, you might also see a shift in personality. One typical type of personality change seen with dementia is a shift from being shy to outgoing. This is because the condition often affects judgment.
Apathy, or listlessness, commonly occurs in early dementia. A person with symptoms could lose interest in hobbies or activities. They may not want to go out anymore or do anything fun. They may lose interest in spending time with friends and family, and they may seem emotionally flat.
