Neurological diseases that are usually present in elderly people over 50 years old, such as a history of stroke, Parkinson's, tremors that are not related to Parkinson's but are tremors caused by age, and Alzheimer's and dementia, are among the diseases that people in old age deal with anyway. Do these have an obstacle to replace the joint?

In the case of types such as Alzheimer's and dementia, as long as the person has not lost his awareness of time and place and can easily understand and carry out the orders of the doctor or his companions, there is no obstacle. In the case of a stroke, if a person is paralyzed, in some cases, surgery may be possible, and in some cases, we really can't do anything. In the case of Parkinson's as well as non-parkinsonian tremors, the degree of disease control and the degree of muscle spasm in these people are important. If their disease is under medical control, there is no obstacle for joint replacement surgery.
