[|Human|] I no some one who has a split kind of personality his voice is usually very deep,and is a friendly guy but the other day he was crying like hysterically crying, talking to him self, screaming and put on a child like voice, for no apparent reason. he then talks to some one and carrys on in this child like state then walks off turns around n flips straight back to normal, it was like he didnt even no it happened what could this be?
[|AI|]  His understand your concern. Split personality is dissociative disorder means dissociation occur from self and replaced by another identity with same kind of features that have you mentioned in your query. Sudden crying and change in voice are suggestive dissociative phenomena. Need to evaluate properly so consult psychiatrist and get help. It can be treated with varieties of modality depend upon presentations. Still have query then feel free to ask. Thank you.
