Sudden memory problems
To recall data or a given event, you need to record the information in your mind, maintain or store it, and be able to retrieve the information when needed. Brain tumors may affect any of these processes to maintain a healthy memory. The areas usually involved with keeping and recalling memory are the temporal lobe and the frontal lobe, which means that tumors in these areas would be more likely to cause memory problems. Some patients experience retrograde amnesia, which is a loss of memories stored in the brain before the tumor started, while others would have anterograde amnesia, which is defined as a difficulty in storing and recalling new memories after the tumor starts to give out symptoms.
