Mental Illness (Psychosis)

In this chapter:

Similar signs can be caused by illness, poisoning, medicines, drug abuse, or a head injury. A health worker can help determine this.

A person with any of these signs may have a mental illness, especially if they happen often or interfere with daily life:

  • She hears voices or sees or hears things that others do not see or hear (hallucinations).
  • She begins to have ideas that are not true (delusions) which make her act in dangerous ways or affect her relationships— for example, she thinks that loved ones are trying to rob her.
  • She no longer cares for herself—for example, she does not get dressed, clean herself, or eat.
  • She acts strangely and there is no explanation for why she is acting so differently.

Along with needing treatment, any person with a mental illness should be treated with kindness, respect, and dignity.

If you notice someone acting differently than usual, consider if community beliefs or traditions can explain it rather than mental illness. For example, if a woman says that she received advice in a dream, she may be drawing upon traditional sources of knowledge and guidance, not suffering from mental illness.
