Dear Welcome to HCM We understand your concerns I went through your details. The given symptoms do not warrant treatment for memory loss. These symptoms simply correspond to disorientation which could be due to stress. You should talk to your husband regarding this matter. Take the hole one week history of your husbands work schedule at the job site. Note down everything, including stressful and non-stressful. You should get a pattern. When a person is too much stressed, it is natural to have disoriented feeling and illusions. That does never mean, he is having memory loss or some other serious problems. How ever, you should keep the log handy. Whe he has it again (possibly could happen again because stress is inevitable) note down everything again. You should consult a physician if the same symptoms appear for the third time. The physician will check allthe vitals and once he clears your husband, you should consult a psychologist / life trainer for stress management. Relaxation, breathing, physical exercises etc helps.
