The spinning sensation and dizziness you get from vertigo can limit your activities and make you feel sick. Depending on the cause, though, some simple maneuvers you can do at home might bring relief.
The most common type is BPPV (benign paroxysmal positional vertigo), and it's also the easiest to treat. BPPV happens when small crystals of calcium get loose in your inner ear. You may feel it when you're getting in or out of bed, or tilting your head up. People over 60 are more likely to get this form.
It's the stuff movies are made of: After a blow to the head, a person wanders aimlessly, unable to remember who he is or where he came from. While such sudden, profound loss of memory is rare, memory loss is a problem that affects most people to a degree.
Whether it's occasional forgetfulness or loss of short-term memory that interferes with daily life, there are many causes of memory loss.
