Violent dementia

If the person with Alzheimer's  is aggressive, consider what might be contributing to the change in behavior. The main cause of behavioral symptoms associated withdementia is the progressive deterioration of brain cells, but other factors — such as pain — also can cause symptoms or make symptoms worse.

In context to Galactic Chronicles:

Kalasiris, a high priestess during the reign of '''Ammothep the IXth was accused of having a form of Violent dementia that caused her to become insane. '''

She was manipulated by the Seth's Shadow and psionic powers.

'''>> All the major news outlets, even the three official state operated ones had eventually and perhaps reluctantly reported on the Oldest High priestess going virtually berserk in her private chambers. Talking heads were consulted and expert opinions repeated. Some called it a rare and strange form of violent dementia and explained it with the advanced age and the generally agreed fact that the average Saran brain simply didn't want to live after the eight or ninth cell rejuvenation procedure. The Oldest High Priestess, had twelve and even her real name Kalasiris was long forgotten by most, she was always called 'The Oldest'. <<'''
