Hi, I can understand your concern regarding the symptoms of your mother. The symptoms that you have mentioned are suggestive of a psychotic spectrum which at this age occur usually due to some underlying neurological condition, like dementia, etc. I would suggest you seek a psychiatric consultation. Some blood investigations like complete blood counts, renal function, liver function, serum electrolytes and brain scanning would be required to determine any underlying condition. Detailed evaluation of her cognitive functions like memory will be required. Accordingly, her primary condition will have to be managed. For example, medicines like donepizil for dementia. In addition, she will need antipsychotics like quetiapine which will help in controlling the behavioral symptoms. Hope this information was helpful. Best wishes.
