What are signs of serious mental illness (SMI)?

It is unusual for a person with serious mental illness (SMI) to suddenly lose total control of thoughts, feelings and behavior, without there being some warning signs that the person or his family members have recognized.

  • Sleeplessness
  • Ritualistic preoccupation with certain activities
  • Being suspicious
