Some forgetfulness is a normal part of growing older, but it’s important to be aware of changes in your loved one’s memory and signs of a more serious memory loss condition. If your loved one has a degenerative condition like Alzheimer’s or another form of dementia, an early diagnosis can give you and your loved one time to develop a long-term care plan that honors their care wishes. Sudden changes to your loved one’s personality are often another sign that something’s not right. These changes can include anxiety, paranoia, depression, and socially inappropriate behaviors, as well as sudden mood swings and physical aggression.
