What to do when mom is in denial about psychosis?

Do you mean if you bring up your mom's strange behavior and paranoia to her she just gets angry instead of accepting what you say? That doesn't seem too unusual to me.

Have you tried to talk to your dad about this privately? Do you think he is aware of her changed behavior, or is he in denial? Does he need a lot of help, for example with medications, from your mother?

What did the doctor say about the seroquel dose? How long should you observe the results before increasing it?

It is probably too early to panic. Maybe the seroquel will control the symptoms. If not, perhaps another drug will. But use this as a wake-up call to make some preparations for the future. Do your mother and father each have a health care directive? How about DPOA? Have they done any preplanning for their funeral costs? You can begin to talk to them about these things simply on the basis that they are getting older, and it is best to do these things while they able to think clearly. They don't have to accept Mother's impairments in order to take these sensible steps.

You and your sibs need to keep an eye on things. If Mother continues to decline it may be necessary to bring in some help.

You asked a question about psychosis but never followed up on it. Why is it necessary for your mom to even be aware of it? I would suggest you ignore speaking of it and ignoring strange behavior as much as possible.. Just tell her in a calm voice what you want her to do. Is she worse since being on the med.? Learn more about the hydrocephalus also. The behavior might be linked to that. Has she been checked for memory loss and dementia by a neurologist? Good luck and many hugs. Corinne

Could your mom's behavior be related to a mild dementia? Dementia sometimes causes people to think family members are hiding things, keeping secrets, talking about them, all because they are struggling with memory loss. The first effect you might see from Seroquel is sedation---actually a side effect. another side effect is weight gain. At this point about all you can do is offer support, and perhaps convince your parents, on a good day, that it would be wise to do a little 'future planning'.
