Aggressive thoughts symptoms and conditions

My mother started taking Ambien CR around a year ago about this time last summer. Almost immediately I noticed a severe change in her mood and demeanor. She started experiencing tremendous mood swings, delusions, paranoid and aggressive thoughts, sleepwalking, eating and others activities while asleep and waking up not remembering a thing. In a matter of 4 months she had totally lost the ability to think or care for herself. Her house was about to be foreclosed on because she hadn't paid any of her bills in 4 months! Not only that she had been throwing away all of he mail and business information so even when I tried to take over the finances I couldn't because there was no paper work left to find anywhere in the house. To top it all off she was going through the process of preparing for a surgery on her back that she had been waiting for almost a year.
The surgery was supposed to last a few hours and then she would have to stay in the hospital for 1 week for recovery and then do a couple more weeks of rehabilitation. By this point though she had been taking the Ambien every night for about 5 months and at 2am about twelve hours after surgery I received a call from the hospital saying that my mother was catching a cab home from the hospital and had signed herself out against doctors advice. They also told me that she was having paranoid delusions that people were watching her from the parking lot of the hospital and that the hospital was trying to overly drug her up. My mother confirmed these statements as the security guard handed her the phone to try to have me persuade her to stay.
She couldn't remember anything or do anything and her delusions were getting worse. One evening it got to the point where the delusions combined with her back pain sent her by ambulance into the emergency room. While going thru intake she couldn't even answer basic questions like her name and age with out prompting from me to have her answer. This brought up a huge response from the intake nurse who asked if the only reason for the visit was back pain or if something else was wrong. She was then transported to a crisis center for an evalutation, which made her mood severely extreme she became verbally aggressive defensive and paranoid. Before the crisis center could even complete an evaluation they had to come and ask me about her basic medical history because she couldn't even correctly give them that information.
After they finished the evaluation they came to the conclusion that my 49 year old mother either had schizophrenia or dementia! These two mental disabilities do not just manifest themselves in people who them and their families have no history. The interviewer, staff, and doctors were at a complete loss and had no idea what was going on or creating my mother’s mood swings and bizarre behavior. They tried to threaten her to get her to sign herself inpatient saying that if she had come back again she would not have a choice but that didn't work. State law requires that only a person that is harm to himself or herself or someone else can be admitted into an impatient crisis ward and since she had made no such threat nothing could be done.
I started to talk to her doctors finding out that they were noticing the came bizarre behaviors that were not present before and accumulating a list of medications that she was on. After fully investigating the possibility of a drug interaction between the medications and the possibility that she was experiencing psychosis and finding out that that again was not the cause I became even more discouraged and frantic. Then I started to talk to some of the students at my college and found out that they were also experiencing the same problems either in their own lives or with their loved ones the only commonality between the collections of people I talked to that were experiencing the same problems was the drug Ambien. I immediately called my mothers doctor and he advised me that must be source of the problem and for her to stop taking the medicine. It took about 2months for my mothers’ mental state to return to normal but it has taken over a year and a bankruptcy to clear away the damage that Ambien had created in her life.

I am a 57 year old man, who has been suffering from asthma several years. This spring my doctor put me on Singulair as an additional medicine to my cortisone-inhalator. after one month I feel symptoms of depression an mood-changing, severe ups and downs.
AND - as an additional symptom i have partially lost my feeling in some fingertips, and now parts of my left thumb and even a feeling of "cold2, mostly in my left hand.
anyone who share that symptom?
