Hello,
He may have a form of
dementia referred to as LEWY BODY DEMENTIA or
LEWY BODY DISEASE.
In this illness patients often will hallucinate. They may also exhibit other behaviors such as unreasonable or unfounded fears,
paranoia, the sense that people are following, watching, or even stealing from them.
If he's been tried on medications such as
Risperdal (
risperidone), Haldol (
haloperidol) he may get even worse so I advise caution to the physician who may suggest this approach.
Your best bet is to connect with a
neurologist for an overall examination and review of the history to determiner what tests or imaging studies, as well as blood work, may be helpful.
I know you say that he has medications for memory, however, long term data has unfortunately not revealed very much efficacy of these medications and so approaches that are more proactive in getting him and keeping him involved in activities of a hands-on, as well as cognitive nature, may be helpful.
PHYSICAL EXERCISE is a terrific way to make things a bit more manageable aside from the cardiovascular and cerebrovascular benefits he may reap.
You may also look into dietary changes that include more antioxidants in his system and less complex sugars and carbohydrates. Reduce saturated fats and oils and you may witness some improvements.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
