Sister Domestic Life in Mess - What to do

Hi Everybody,


My married Sister have been diagnosed with Paranoid Schizophrenia , and hence she is now staying with us for having good family therapy along with medication. During her stay I have noticed that  my nephew who is 4.5 yrs old is clearly showing symptoms of ADHD and also my brother-in-law showing clear symptoms of Adult ADHD, I was not aware of this disorder earlier and its only recently came to know about the ADHD. It seems that my sister life had become hell dealing with 2 ADHD person 24 hrs a day in a nuclear family  for past couple 4-8 yrs which may be one of the important factor of her's Schizophrenia from the past 2 yrs. Now she does shows improvement but gets stressed sometimes when she communicates with her husband or have to take care of his son. 

After getting medical treatment for my bro-in-law(clinical diagnosis  is still pending) I am in dilemma w.r.t what to do , for the following reasons.

1. As Both Schizophrenia and ADHD requires Behavior therapy along with Medications, Can I expect my sister and bro-in-law to behave in conjunction with therapy towards each other given the above disorder they have.

2. Would Medications would be good for my 4.5 yrs old nephew given the fact that he is already underweight and is just 15 kgs.

3. Can I expect proper behavior from my bro-in-law and sis towards my nephew if they again moved in nuclear family (As of now i am highly disappoint the way they behave with him.. like surrendering to his demands most of the time).

Please advice,





By the time my nephew and brother in law have been diagnosed with ADHD
