What are the symptoms of confusion or decreased alertness?
Many health problems cause confusion or decreased alertness. It is not unusual for a person who is sick to be sleepy or confused when he or she wakes up. But extreme sleepiness may be a symptom of a more serious health problem.
Confusion
Confusion may range from mild to severe. Symptoms of confusion may include:
- Jumbled or disorganized thoughts.
- Unusual, bizarre, or aggressive behavior.
- Having trouble solving problems or doing tasks that used to be easy for you.
- Not knowing where you are or not recognizing family members or familiar items.
- Firmly held but false beliefs (delusions).
- Seeing, hearing, feeling, smelling, or tasting things that are not really there (hallucinations or illusions).
- Unfounded suspicions that others are after you or want to harm you (paranoia).
Decreased alertness
Decreased alertness occurs when a person is not fully awake, aware of, or able to respond normally to his or her external environment. Decreased alertness may also mean that a chronic illness has gotten worse.
