Hello! Welcome on Healthcaremagic! Your memory troubles could be related to difficulty in concentration and depression. The fact that you cry during the night is another argument in favor of this disorder. At your age, dementia would be really an exceptional diagnosis. But, you should know that the management of depression would improve your concentration and memory problems. There is no need to take any memory pills. I would just recommend consulting with a psychotherapist and performing a lot of physical activity (Yoga, aerobics, running, etc.). If this does not help, an antidepressant may be necessary. But you should discuss with a psychiatrist before taking any medication. Hope you will find this answer helpful! Best wishes, Dr. Aida
