5. Bad Judgement.
Part of being an adult is making judgement calls that are responsible and safe. When the older adult begins to show signs of dementia, these responsible judgements begin to dwindle and it can actually cause the mind to revert back into childhood (in the sense that judgement calls are no longer supportive of good, sound decisions). If you notice that your friend or loved one is making poor judgements in many life decisions, it is best to talk with them and possibly seek out professional help. Your doctor is the one who can help give direction and guidance on this type of issue and sometimes it is a challenge to seek help with the person affected.
