Hello and thank you for using JustAnswer. It would be highly unlikely that the medication interactions you described would cause a "selective" psychotic break and aggression towards only family members. Typically any medication interaction that causes psychosis and aggression would manifest in a variety of ways, and not just towards those that are closest to the individual. While the individual may have more pronounced aggression and psychotic symptoms towards those that they know very well, there would still be some elements of such a psychosis and aggressive response towards acquaintances and strangers too. So it would be unlikely for the individual to act euthymic or "normal" with non-family members and psychotic/aggressive with family members as that is not how the symptoms of these disorders work
It is possible that he may be a chemical imbalance, but again for it to be so selective to only affect his interaction with family members is considered unlikely. Chemical imbalances such as Bipolar Disorder would also affect his interactions with non-family members as well. I cannot diagnose your husband without a face to face assessment, but given all the medications he is on there is a possibility that this could be an abnormal interaction or there is the possibility that your husband is choosing to be aggressive with you and other family members and malingering the "psychosis" to rationalize his behavior.There are multiple possibilities here and he would require a face to face to assessment to narrow down the possible cause of his behavioral change.
It could be the medication. It could be a possible Bipolar Disorder or another mood disorder. It could also be Dementia. There are varying causes for this level of behavioral change. He needs a face to face assessment to determine what the exact diagnosis would be
Please let me know if you have any questions or concerns as I am happy to assist and support you regarding this issue.
