Okay so my mom is 56, And her mental state has been changing and declining. About 2 years ago she was perfectly fine except she WEIRDLY couldn't talk on the phone, like if she got on the phone she would act like she does now all the time, which let me explain. okay so my mom use to act perfectly normal right? Well now my mom can't drive, cook, do her Abc' S Or anything! but the most weird thing is first she would see snakes everywhere that weren't there. my dad took her to a doctor they put her on medicine now she no longer sees snakes but, now she doesn't know how to speak right. Lets just say my parents bring me something my mom gives me it and I say "thank you" all she will do is repeat what i say very slowly. she also goes on all the doors an tugs at the door knobs and randomly walks into my room looks at me and leaves, it's so weird. Again she got like this in a span of 3 to 4yrs. and it really upsets me it's like my mom isn't even with me anymore she's like a slow parrot. And it sucks even worse because my dad's had 7 heart attacks so he could pass away soon and i'd be left with a non functional mom, also my dad's taken her to get her head checked and the doctors appearently say nothings wrong which is bs and I honestly think my dad's in denial he thinks that she will get better with social interaction which is bs as well But please anyone in here who can diagnose what she has I would REALLY appreciate it.
