### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
In patients with brain injury, is there a higher risk for subsequent brain injuries, even if the cause of the subsequent injury is not apparent? In a long-term care facility for rehabilitation, we see patients plateau and remain stable for several years only to suddenly seem to lose memory function.

### output:

Hi, welcome to our site. I am Chat Doctor, MD. Read your query. That is a very significant question and I appreciate your problem. I will try my best to answer your query see, I have observed something very similar in my practice. I have some data on the same. Furthermore, I have not been able to find a very suitable reason for these observations. The possibilities that suit one subset of patients fails the second subset absolutelyHowever I feel, and many colleagues agree that the possibility is that people who develop fall, especially the elderly have a component of dementia left behind. Now when there is a level of dementia left back, the person always has more falls. Besides, many of these patients are old and have issues with other aspects of health too like bone health, joint health. These secondary health issues may also make them unstable on their feet and lead to them loosing their balance. And of course, elderly when they fall, often develop fractures and the bed rest that they are prescribed only further adds to the dementia and taxes their cognitive functions. A study of functional MRI may probably help us in getting to a hypothesis, but the costs are an issue hope this helps you. Inform the reports mentioned above/if any other, so I can be of help further. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)Best of luck. Chat Doctor.
