The recent decade has seen deadly viruses like HMPV, SARS-CoV-2 (COVID-19), Ebola Virus, etc., which can be diagnosed and cured. Also, various preventive medicines and vaccines are invented for preventing the virus from affecting individuals. There are other diseases that are predominantly increasing in the geriatric population in recent years, like Alzheimer’s, Parkinson’s, Dementia, and Sleep Disorder. These can be categorized as neurodegenerative diseases. The major challenge in these is that the neurologists are not able to diagnose this disease at an early stage, and the progression of the disease is quite rapid. When these diseases are detected and diagnosed at an early stage, there is a strong possibility to reduce the death rate and increase the patient’s life span. This paper focuses on analyzing the various methodologies and techniques currently available for diagnosing and detecting the major symptoms in Parkinson’s patients termed as Tremor. The tremor can be either a Rest tremor or a Postural tremor. This is an early symptom of any Parkinson’s patient. When this symptom is detected in an early stage, it can be a great relief to the care takers and also help the patient to lead a smooth life. A comprehensive survey of the methodologies, challenges, and future enhancements are highlighted in this paper. The final results obtained are also analyzed using parameters like Precision, Recall, and Accuracy.
