Abstract:
The diagnosis of Parkinson's disease (PD) requires ruling out other causes of parkinsonism. Among various "other" causes of parkinsonism, neurodegenerative causes or "atypical parkinsonism" are the most difficult to diagnose. Most common diseases are "synucleinopathies": multiple system atrophy and dementia with Lewy bodies and "tauopathies": progressive supranuclear palsy and corticobasal degeneration. Unexpected or atypical signs and symptoms for PD, also called "red flags" along with absent or poor or short-lived levodopa response may be a clue for the diagnosis. Some tests may also support the diagnosis, among them, structural (MRI) and functional brain imaging, autonomic function tests and urodynamics, oculographic recordings and neuropsychological work-up, are the most useful.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the test...

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
