Loss of memory: There are some categories of memory loss - (a) short-term memory loss and (b) long-term memory loss. Inability to remember names, time, food, and recent events comprises short-term memory loss, whereas not being able to recognise the birth date, marriage anniversary, etc., is long-term memory loss. One may forget the way to their home, where they are at present, and what should they do next.nCommunication issues: Someone with dementia would find it difficult to understand words. It would also be hard for them to communicate their needs. Their speech would include repetitive questions and other problems with comprehension.nDifficulty in daily activities: As the person cannot remember how and when they need to do certain things, there is initial difficulty in performing basic tasks. It eventually leads to a continuous dependence on caregivers.nChanges in behaviour: The person would also experience anxiety, depression, irritation, and mood swings in increasing intensity.
