Some Causes of Forgetfulness or Confusion

Forgetfulness and confusion are not necessarily signs of aging or brain disease (see our March 5 post). The following are treatable causes:

• Lack of alertness can be a side effect of medication or the interaction of several medications.
• Dehydration diminishes blood volume and may reduce the oxygen supply to the brain.
• Lack of certain nutritional elements - especially sodium and potassium - may affect the brain's functioning.
• Infections, such as urinary tract infections, pneumonia or other treatable medical problems may lead to confusion.
• Hearing or vision problems may affect what you learn and remember.
• Depression or anxiety can result in decreased ability to concentrate and remember.
• Retirement or less structured days may make your recollection of the day and its date less significant.
• Lack of social involvement to help you "stay in touch" with what is going on in the world may leave you feeling "out of it" or confused about the date or day of the week.
• Not paying attention to what you are doing, seeing or hearing may prevent events from being stored into memory.
• Use of alcohol can affect mood, memory, speed or reactions.
