Hi Roger,
Firstly, if you have a loved one that is suffering from Alzheimer`s Disease or senile dementia, I am very sorry. It must be so difficult to watch a loved one deteriorate mentally. My father-in-law has a form of dementia where he has absolutely no short-term memory; but has retained his long term memory. While it is difficult trying to carry on a converstation with him, it's nothing compared tot he pain that others must experience when their loved one doesn't even recognize them.
Swedenborg wrote that on the other side, we are freed from any kind of physical defect - whether that's the physical body or the brain. The mind is independent of the brain.
From my understanding of Swedenborg's writings, when we are born, we have two bodies - the physical one which encases the spiritual body. The spiritual body looks very similar to our physical body - free from defects. When our life in this world ceases, we merely "discard" our physical body and are immediately in the Spiritual World.
Sometimes, transitions are gradual. If the person didn't know about the other side, the angels help with a gentle and gradual transition. According to Swedenborg, they take every care to replicate our earth-home so that when we "come to" we are not overwhelmed. Swedenborg wrote that it was a gradual 3 day (even though acknowledging that time and space do not exist in the spiritual world the way it does in our world) awakening.
Dave Sonmor wrote the following quotation in his article: "The Adoramus: Our Faith in the Glorified Lord":
************************
"There is no great change in us when we die and enter into the spiritual world. We are basically the same character and personality which we develop and become while we are here in this world.
Some people confuse this teaching with the idea that we are only what we are at the moment of death, but that is not so. You might say we are a composite of all we have been during our lifetime some of it good and some of it bad, some of it loving and some of it hateful. But somewhere in our complex life we always have a prevailing love, a dominant will, that is present, which underlies all that we think and do."

****************************
"The second state [of death - after the initial crossing over and could be likened to a life review] can produce some surprises. [There may be] many who, while on earth, appeared to be good and wise and were respected by everybody are now seen to have been motivated by self-love or love of the world. All their respectability now falls away, and they plunge into unrestrained selfishness or acquisitiveness. Another person may have been a drunk or wastrel on earth, scorned by "good" people; or perhaps even a criminal - who knows? Yet in their heart they may have longed for better things; in which case, their good ruling love will now take over, and their disreputable exterior will fall away, leaving them sweet and angelic, as they always wanted to be."
