Symptoms of self-talk can have a person who is whispering and dribbling, with a rather flat, withdrawn expression, and possibly talking into the air or hurling insults into the air, with an expression that can be more nervous, fearful, angry, or hostile. This condition is most often seen in schizoid personalities. People with this personality trait tend to be more withdrawn, socially withdrawn, and alone, often alone, and may feel very lonely and bored and talk to themselves. This condition suggests that family members and friends, be more caring and supportive so as not to develop a mental disorder such as schizophrenia. It may also be seen in the elderly, and is related to the decline of cognitive function in the elderly. In addition, functional mental disorders and organic mental disorders, such as depression, schizophrenia, dysthymia, delirium and epilepsy, may also cause self-talk.
