12-Anxiety
Anxiety is deeply associated with depression, and sometimes, they are both at the same time in the same patient. Similar to depression, anxiety is also triggered by a reduction of serotonin in the brain, which is triggered by Parkinson’s disease. Additionally, patients with increasing symptoms, slow movements, and so many difficulties and limitations often feel anxious and nervous. One common concern in these patients, especially in older adults, is the possibility of falling and enduring a fracture. This and many other recurring thoughts contribute to feeling anxious and often leads to depression at some point.
