Hello & welcome! If you have any questions after reading my answer, be sure to let me know.
Cognitive therapy may be indicated in this situation if the pharmacist has specific issues like anxiety, depression or significant behavioral problems.
CBT has been applied in both clinical and non-clinical environments to treat disorders such as personality conditions and behavioral problems
I would recommend a psychological assessment to confirm whether Cognitive therapy is indicated and would be helpful in this situation,
But certainly, i agree with you that a detailed behavioral assessment is a must in this situation where he has suffered such serious CNS diseases....
Do get back for any clarifications, & please leave a positive feedback too,
I can see that you are online
Please let me know if you have any further questions
