Freezing of Gait
Freezing of gait is a common and frustrating symptom of Parkinson’s disease that affects mobility and balance. It occurs when a person suddenly feels as though their feet are stuck to the ground and they are unable to take a step forward. This can lead to falls and injuries, and can significantly impact a person’s quality of life. The exact cause of freezing of gait in Parkinson’s disease is not fully understood. However, it is thought to be related to the changes in the brain that occur as a result of the disease. Parkinson’s disease affects the dopamine-producing cells in the brain, which play a crucial role in regulating movement. As the disease progresses, these cells become damaged, leading to a decrease in dopamine levels. This can cause a range of motor symptoms, including tremors, rigidity, and difficulty initiating movement, which can contribute to freezing of gait. Additionally, freezing of gait can be triggered by environmental factors such as narrow doorways, crowds, or anxiety.
