Hi i would like to ask something,     My sister hasnt been eating alot (hardly) she doesnt sleep or talk.                                                                                                                                              My sister claims that she sees shadows of people that she knows and sometimes sees their face also she hears voices and she has extreme mood swings. She cant control her anger but she tries and then she wants to be left alone.  She never told us before because shes really quite and cries alot now that shes 18 she has told her family. A few days ago she screamed loudly. i wanna know whats wrong with her.

### output:

Thank you for your query. From the description given by you, the symptoms appear to be that of a Psychotic disorder. In psychosis, there mat be symptoms like hearing voices not heard by others (auditory hallucinations), seeing things, faces, shadows not seen by others (visual hallucinations or imagery), extreme mood swings (affect regulation difficulty), wanting to be left alone (socialization), sleep problems(insomnia), refusal to eat and poor self-care (apathy). Sometimes she may also act out to her hallucinations (like screaming). Now a psychotic disorder may be due to Schizophrenia, or Bipolar disorder, Mania with Psychosis, or major Depressive Disorder with Psychosis. Though the young age of onset in this case point towards schizophrenia, a detailed history taking, Mental status examination and evaluation is required to confirm the diagnosis. After diagnosis is confirmed, she would require prompt and adequate treatment with antipsychotics and or mood stabilizers etc. please remember, the earlier the treatment started, better the prognosis for these conditions.I would suggest you to consult a psychiatrist as soon as possible for the same. Hope I've answered your query. Please feel free to contact me for any further clarifications. Best of luck.
