My mother was put on levaquin in late March/early April for a very bad UTI. She was hospitalized and became delirious once on the drug. The hospital insisted she needed to continue with this drug. She didn't even know me. My mother was diagnosed with mid cognitive impairment in 2006 (short term memory) but was doing great prior to getting sick with the UTI. She had seen her neurologist a week before her illness and the doctor was very pleased with my mother's cognitive thinking. Since my mother's return from the hospital, she has had terrible stomach pains, diarrhea, and her short term memory is horrible. She was independent prior to her illness and now she requires assistance. Will she ever get better? I am beginning to think the levaguin has severely impacted my mother's health.
