Welcome to Just answer !
Well, i value and understand your concerns about your grandmother's condition , and from what you have narrated it seems like she is suffering from Dementia and Depression both right now.
You see her advancing age is the possible reason for ther Dementia and let me explain to you that Dementia is a slow progressive deteriorating illness which is more than a single entity but a goup of conditions clustered together which include depression , anxiety , agitation , mood swings , rage and stubborn attitude all included into one.
Also, this condition will become increasingly taxing on the caregivers having to put up with the illness manifestations..
So, the best thing that we can do is to slow down the process of her illness is to place her on a mix of follwoing drugs which wil ensure
slowing of the progression of illness...
and also calming her down and make her more reasonable with her ever so increasing demands..
The drugs are as follows..
1) Aricept ( Donepezil ) at dose of 5 mg to start with and then raising the dose to 10 mg after a span of weeks and maintaining on this dose ..
2) Namenda ( memantine ) at dose of 20 mg / day to be started at 5 mg / day for 2 weeks followed by 10 mg / day for another two weeks and then progressing to 20 mg / day and maintain on it.
3) Lexapro ( escitalopram ) at dose of 5 mg / day in morning dose only ..
4) Continue on the anti anxiety drugs as she is on right now ..
You see aricept and Namenda are the chief drugs sed for Dementia
and lexaro is a an anti depressant used for depression and anxiety ..
This drug regime shall be discussed with her doctor and then she to be started on this ..
You shall see her melow down and become more tolernat towards others and less demanding within 2- 3 weeks of starting these drugs ..
is this clear ...
i hope this helps..
This will make her to rejuvenate and refresh herself and also make her less angry and overwhelmed and more easy going as a person, which is essential for her caregivers to continue to invest their energy in offering her their best service as her wellwishers ..
