Difficulty diagnosis on early symptoms of Parkinson's

Difficulty diagnosis on early symptoms of parkinson's disease are as follows:

1. Lack of public awareness of the Parkinson's disease
People are not well informed about the early symptoms by public media. There is hardly any publicity on PD in the media.

2. the lack of neurological services

As far as I know there are shortage of neurologists who are specialised with movement disorders not to mention the uneven distribution of the specialists . Consequently, most sufffers of Parkinson's are first seen by general practitioners who may not be familiar with the diagnosis of PD.

3.The nature of the onset of early parkinson's

The early symptoms of PD starts very slowly and in a silent manner.
Notice of early Parkinson's are slowness of without knowing exact cause,
smaller in handwriting, mask face without smile, blurred vision, slurred speech, stoop posture
