Parkinson’s disease
As a movement disorder, Parkinson's disease is the second most prevalent neurodegenerative condition. Some individuals only experience a slight tremor in one hand at first, and it gets worse with time. Although a tremor is perhaps the hallmark of Parkinson's disease, it is also usually accompanied by solidity or a halting of growth. In the early stages of Parkinson's disease, the patient may show almost little facial expression or walk without swinging their arms. They could appear to have sensitive or slurred speech. As the patient's condition deteriorates over time, the symptoms of Parkinson's disease get worse. There have been considerable improvements in our understanding of Parkinson's disease in recent years.
The initial stage of mild memory loss, which is most likely caused by an inability to do important tasks, is Alzheimer's disease. Alzheimer's disease is a mental condition that slowly robs people of their memory, their capacity to reason, and even their ability to perform the most fundamental tasks. Dementia that is caused by Alzheimer's disease deteriorates over many years. Although Alzheimer's disease begins with little memory loss, as the illness advances, it gets harder to carry out daily tasks and interact with other people. Alzheimer's has no known cure, but there are effective treatments for the symptoms, and research is ongoing.
