I think you mean "schizophrenia",right?
Bipolar disorder is a mood disorder characterized by alternating states of depression and mania that follow each other in a repeating cycle.

People with bipolar disorder may cycle through these states quickly or may experience long periods of depression or mania. Often one mood state predominates, while the other occurs only infrequently or briefly.

Symptoms of the elevated mood stage of bipolar disorder include an exaggerated sense of confidence and well-being, racing thoughts, excessive talking, distractibility, increased desire for pleasurable activity, decreased need for sleep, impulsivity, irritability, and impairment in judgment. The depressed phase includes symptoms of sadness, fatigue, pessimism, feelings of helplessness, low self-esteem, and loss of interest in life, possibly with thoughts of suicide.

Schizophrenia is a common and serious mental disorder characterized by loss of contact with reality.

The behaviors, described below, must be present for six months or longer to establish a diagnosis. Approximately 1% of the world’s population is affected by this condition.
Symptoms and signs of schizophrenia include loss of contact with reality (psychosis), auditory and visual hallucinations (false perceptions), delusions (false beliefs), abnormal thinking, restricted range of emotions, diminished motivation, and disturbed work and social functioning. People with schizophrenia may also engage in speech that does not make sense, exhibit silly or childlike facial expressions, and experience poor memory or confusion.
