Mental confusion or decreased alertness is the inability to think clearly and quickly. When confused, one has difficulty concentration, paying attention and may feel dizzy or depersonalized. Confusion interferes with ones ability to make decisions clearly and correctly. Many health problems cause confusion or decreased alertness. Decreased alertness may occur when a person is not fully awake, aware of, or able to respond normally to his or her external environment. Decreased alertness may also indicate that a chronic illness has worsened.
