Memory

The memory that fades slowly

We are, to a great extent, what we remember. Caring for it begins decades before the first lapse.

“Great is this power of memory, exceedingly great, O my God.”

Saint Augustine, Confessions, Book X

There is a question I hear often in practice, almost always at the end of the conversation, almost always in a lower voice: “Is it normal to forget names?”

The person asking is rarely worried about names. They are worried about what names might announce. For someone who has built a whole life with their own mind, few ideas are as frightening as losing it little by little.

Saint Augustine, sixteen centuries ago, stood in wonder before memory. He called it a palace, a vast field, a place where we keep images, words, affections and even forgetting itself. And he wrote, with a simplicity that still astonishes:

“There I also meet with myself.”

He understood what neuroscience confirms: memory is not an archive. It is where identity lives.

What is normal

Not every lapse is a sign of disease. Forgetting where you left your keys, taking a while to recall a name that returns an hour later, walking into a room and not knowing what you came for: all of this happens to healthy brains, especially when they are tired, overloaded or poorly rested. The memory of someone doing ten things at once fails more for lack of attention than for lack of memory.

What deserves attention

What deserves attention is different. Forgetting what was discussed yesterday, not just a detail. Repeating the same question. Getting lost on a familiar route. Struggling with what used to be automatic: figures, the diary, a simple decision. Often the first sign does not come from the person who forgets but from those around them. A spouse, a partner, an assistant notices first.

Even a real change is not always the beginning of something irreversible. Low B12, a slow thyroid, pauses in breathing during sleep, depression, side effects of medication, too much alcohol, hearing that declined without anyone noticing: all of these imitate forgetting, and all of them can be treated. Before fearing the worst, one must rule out what can be solved.

What can be protected

The brain at eighty begins to be cared for at fifty, sometimes at forty. Blood pressure well controlled for decades. Blood sugar in order. Deep sleep. Daily movement. Hearing looked after, because hearing poorly isolates, and isolation impoverishes the mind. Conversations, friends, bonds. And the habit of learning difficult things, which keeps the brain challenged. For those who carry a genetic tendency, knowing early condemns no one; it simply brings the care forward.

Over years of practice I have learned that the fear of forgetting usually arrives long before any real forgetting. And that this fear, on its own, already takes away clarity: someone who keeps watch over their own memory pays less attention to the present, and remembers less of it. Sometimes the first treatment is a serious assessment that calmly separates what is normal from what is not.

There is also what no test measures. Memory does not belong only to the one who carries it. It belongs to the children who want to hear the story again, to the company that depends on someone who knows why each decision was made, to the family that recognises itself in someone’s recollections. Caring for your own memory is also caring for what others will receive.

Augustine met himself in memory. Caring for it is, in the end, caring for who you are.
