Thank you for your reply but I don't think you fully understood the situation. Patient was given an anti-psychotic which reversed the initial severe "dementia" symptoms to an almost normal state. Now within days, 1.5 years later, patient reverted almost back to the dementia state. However the doctor is saying the Alzheimers has simply progressed.

Plus, you should understand that while assisted living facilities must keep records the system is not 100% guaranteed. A medtech may simply indicate in the records that medication was given, without actually giving the patient the medication for example. I believe this happens for a variety of reasons, such as pure laziness for example.
