Parkinson’s Disease or PD is among the most common of neurological disorders found among the elderly. Please note that this doesn’t mean that middle aged or even younger people cannot develop this condition. However, Parkinson’s disease’s prevalence is largely limited to the older segment of the population. This also makes diagnosing PD rather difficult. This is because many of the old age symptoms are quite similar to the typical symptoms of neurological disorders like PD. This includes excessive tremor-like sensation in various parts of the body and postural problems. The affected individual is likely to suffer from increased heart rate when taking upon the slightest of physical activities, bradykinesia and decreased stimulus acuity.

Most of these symptoms are likely to be interpreted as anxiety or other old-age conditions like weakness of the bones or a gradual decrease in neurological acuity rather than neurological disorders like Parkinson’s Disease. In some patients of PD, the symptoms can worsen beyond healthcare management. This happens when PD affects multiple systems of the body and induces palsy and gradual dissemination of existing neural pathways. This condition is also called Parkinsonism. Such type of neurological disorders rarely happen secondary to other causes but PD due to manganese poisoning has been archived. Such rare neurological disorders are referred to as accidental neurological disorders, i.e. accidental Parkinson’s Disease.
