Guidance:
This is not permanent damage, not irrecoverable. However, the first thing to do is to improve the depression, only depression is better, the recovery of memory can be better. This can be noted recovery, but slower, this have to have confidence in themselves, if there is no confidence in recovery can not really recover.

Our body and mind are one, like nature. The body and mind are one and the same, just like nature, which changes all the time. It is the body's intelligence, its primal fear of survival, its fear of change, that makes illness occur, and it is the body's change in response to stimulus or injury.
We do a lot of things that hurt our bodies, yet we demand that the body's functional responses remain normal, and as soon as the body reacts abnormally, we rush to suppress it.
So the symptoms of disease are meaningful, and we always habitually ignore the self-protective signals that are being activated by the body. In the face of our sophisticated wisdom and integrity of the body, due to the damage left by the mind, the same will be reflected in our body. Therefore, it is an unchanging truth that the mind is the first to be cured.
The sudden onset of a dementia-like state under the influence of mental factors is characterized by "forgetfulness" (sometimes a real loss of memory), a lack of common sense, and speech and mannerisms that are not in keeping with one's actual age.
There is also an inability to perceive the surrounding situation correctly, somewhat similar to the symptoms of Alzheimer's disease, where the person is, what time it is, and the relationship between people can not be clearly judged and distinguished.
So, the process of scientific treatment of depression is very important, if you can not remove this dementia or stupidity of the situation, said that the cure of the patient to return to society, but also unscientific.
