In my case, I have a TBI from being hit by a bicyclist in 2014. A year or two later, I began to experience anomic aphasia. Though I haven't been seen by a doctor for this, I know, from years of reading and experience that it is anomic aphasia. I can be in a conversation, or writing or thinking about anything and, at some point, there may be a word, a name or a phrase I want to use, but it's just "not there." This will typically continue for seconds, minutes, or in rare cases, hours before the word pops into my mind. It's frustrating more than anything, as it impairs my ability to communicate. Those people who know nothing about anomic aphasia will assume the problem is "memory loss," but the memories are still there. The problem is one of recall and most people think memory and recall are the same thing, but they are not. The fact that I recover and say the word just moments later proves the memory is still intact. As for my memories, everything I see, hear or directly experience will become a part of my long-term memory. I have an undiagnosed case of Hyperthymesia and revisit memories from as long ago as age 4, sometimes whether I want to or not. Yet, despite this, anomic aphasia is a problem for me because it doesn't involve my visual or auditory senses. It is only words, whether written or read, that are affected. Some words (and names) seem to give me more trouble than others, but I will eventually recall them. It just takes longer.
