Treatment of hemorrhoids is divided by the cause of symptoms, into internal and external treatments. Accurately classifying a patient's symptoms and the relation of the symptoms to internal and external hemorrhoids is important.
Note also that the average life expectancy after being diagnosed with Parkinson's is about 9 years -- hence, those who participated were already at this point at the beginning of the study.
In other words, over a period of 8 years, after having had Parkinsonâs for over 9 years, on average, when the study began, just over half (54.5%; 122/224) developed dementia. About the same number (56.7%; 127) had died.
