Suggest Treatment For PTSD

Question: Sister was diagnosed with possible PTSD been happening for 6 years jerking movements stuttering, hiccup when speaking only when having symptoms, other times throughout the year she is fine then 6 months ago said hospital emergency room visit and hospital stay doctor said possible nervous breakdown of some sort but she would not listen. Never got help now she has declined and thinks people are leaving pictures in house but they pictures that may have been in house as they are from our childhood , thinks people are following her, going in her car, yells and screams uncontrollably, says her mind is racing and can't sleep. Complains nothing in house works, her brand new car is junk, thinks tracking her. etc

She is not on any treatment, has been taking hormone pills thru GYN, yes she had a traumatic event 7 years ago, then in the months that followed she started to get panic attack like symptoms, they escalated to a on and off again uncontrollable body jerking movements with a hiccup sound and stuttering like voice, repeating words when trying to speak example like this ta' ta' ta' talk' talking' stuttering like. Difficulty getting words out, also would stop stuttering when she would get mad and yell.Doctors thought possible seizures but video taping in hospital did not show this. She recently was video taped in hospital in summer with uncontrollable jerking movements said they did not see seizure activity, but after two days she was pacing in room and saying get the lobes off I don't want people watching me. Her trauma happened seven years ago had a incident at work was complaining that someone was getting into her computer and to mke story short taken top a psych center and had bad experience since then has been getting these symptoms but gotten worse over the years. The uncontrollable motions/stuttering/hiccup comes and goes weeks and sometime days. But then this summer doc at hospital thought she may be having nervous breakdown, she would not listen difficult. She has gotten worse has been paranoid for a while but now real bad, thinks people come in house when she is not there. think family is leaving pictures of friends/family from childhood that are real pics but we are not leaving them they must be hers. She complains unhappy where she lives just moved about 5 months ago due to financial reasons,and has gotten worse was fine in warm weather since late oct /nov worse, yells at times and screams historically in conversations " you don't understand," "tell me why are you people doing this to me regarding pictures", if you mention stress yells "yes i am stresses,I havePTSD don't you get it. Then at times can be calm and normal, however since approximately Dec 2013 she has not been good. Conversations consists of talking normal then all of a sudden she starts yelling I would be fie if everyone will leave me alone, and people will stop leaving pictures in my house, and going in my car. Then she will complain the appliances don't work which are newer, the car which is new junk, has no motivation, but is screaming lately during every conversation accusing us of putting pictures in house car etc. Says if your doing this what are you trying to tell me etc. She then at times will tell you my brain is not functioning you don't get it I am not myself, I haven't been myself. I m jerking, stuttering, not going out of the house for weeks at a time. It used to be episodic, with the jerking, hiccup, stuttering and not going ut for days and weeks. For the last 4 weeks plus she has been out of control screaming when talking to family members if she i talking to you if she tells us that people are leaving pics in car or house and we say no thats impossible she either gets quiet and says then how are they getting there or starts yelling unstoppable blaming us this is newer symptoms and has lasted on and off the last several weeks. Will not go back to doctor ays I already went what did they do for me.Not treating now she takes excedrin I know as she gets headaches complains mind racing, can't sleep says paces, we noticed she cannot handle stress when problems come she avoids talking about them and say my brain can process this function I can't talk about this now and avoids all the time when on telephone or confront. She tells doctors I'm suffering from seizures, or mold, it's my brain, its something else always thinks she has some major illness except what is actual happening.

Could this be anything else as she has in the past had one gran map seizure 7 years ago.Any chance could be such as delusional depression, or severe nervous breakdown etc Thanks
