Parkinson's disease is a slow-progressing neurological disorder characterized by a decrease in dopamine levels resulting from the progressive loss of dopamine-producing nerve cells in the brain. This degenerative disease, typically more common in individuals over 60, manifests with a range of symptoms affecting motor control. The disease typically begins with symptoms such as tremors in the hands, muscle rigidity, and loss of balance. Dopamine is one of the key neurotransmitters responsible for chemical communication between brain cells, and it is particularly crucial for the fine-tuning of voluntary movements. The loss of approximately 60-80% of dopamine-producing neurons leads to the onset of Parkinson's disease. The symptoms of the disease can vary significantly among individuals, especially in the early stages.
