My sister is 33 years old and she had got 3 psychotic episodes till now. They all came at the same time in the year, something between October/November (November 2010, October 2013 and October 2014). She went to hospital where she stayed there for 3-4 weeks each time. Each psychotic episode starts by loss of concentration, weak memory and loss of interest in life, then it develops to positive symptoms like disorganized speech and behaviors, delusions, hallucinations, the sense of being controlled by outside forces and disorganized thoughts.
She is unmarried and lives with my old parents (my father is 73 and my mother is 64). I am living in another country. She feels lonely all the time and she is very afraid of living alone after the death of my parents. She feels that she has a great responsibility towards my parents as she has to take care of them after being old. She suffers from being over weight since her childhood and this made her stressed and feeling offense all the time. She hadn’t a normal life like other children. She tried many times to loss weight and went to many nutrition doctors but unfortunately she failed.
On the first 2 episodes, she had some stressful events that led her to these episodes. Before the third episode, there wasn’t any specific stressful event except that she reduced the dosage of medications (lithium) for 15 days because the company that produces it stopped its production and there wasn’t any alternative in the market (she took 1 tablet / 3 days instead of 1 tablet / 1 day).
At first she was diagnosed as bipolar disorder after the first episode, then as after the second episode. I am very worried about her and would like to know some medical questions regarding psychotic episodes in general:
1- Is it possible that the 3rd episode occurred because she reduced the medications dosage to 1/3? Or there are other reasons? She was totally fine just before the episode by 1 day!
2- Is it possible to get more episodes in the future even if she keep medications?
3- Is there any possibility that she get cured? Or these types of disorders can’t be cured forever?
4- what is the effect of multiple episodes on the brain? Is there any brain damage after each episode? Or it is all about the chemistry of brain?
I appreciate your replies as I am very worried and can’t do something except writing in forums!
