Brain and Spine Problems

My father (61yrs) is having Diabetes, Hypertension and Cholestrol for which he is taking medicines. My family background has a history of old age dementia; where I have seen the patient suffers from forgetting even his family members. I want my parents (father and mother both) to get checked up thoroughly as both of them are ageing, and i want to be assured of their good health. Please guide me what are the general tests required for thorough investigation, for which i mean blood tests ( thyroid/cbc/kft/lft/sugar/cholestrol etc ) or any other , if required. Is "full body test packages" in differnt health centres or labs are sufficient? Please suggest..

I've been having a continuous numbness in my right ring finger for tow days now, and I've been feeling pain all over my right arm since yesterday, I had this numbness in my foot fingers too, but it wasn't constant and would go away in a few seconds (still comes and goes). I have a history in seizures for 14 years (I was 9 at the time I first got it, now I'm 23), overweight problem as well (96 Kg), taking the constant headache into consideration, my doctor suspects the possibility of developing into ICP (Intracranial pressure) could this numbness mean anything serious or dangerous considering my condition??
