I am male 46 years old suffering from major depressive since last 22 years. The first episode was very very severe with severe numbness and sleepy throughout the day, complete impairment in memory, thinking n thought processing tried different kinds of depression medications flunil 40, sertraline,veniz 40 etc, even though flunil helped me to some extent but my psychosomatic symptoms like body pains constant fatigue never gone away and also memory impairment n executive n thought processing capabilities not improved much even after medication for 22 years. Cognition n memory impairment was my biggest problem. One year back lamictal 200 introduced along with antidepressant lamictal helped me to a great deal in restoring my subnormal n below baselevel depressive mood lifted to certain extent far better than antidepressant alone. My main concern now is improvement in mood to further extent by using another suitable mood stabilizer along with lamictal n my grave concern of cognition and memory improvement which never returned back .I used to be with excellent n sharp memory and was topper through out my studies until this depression episode occurred. Please suggest add on medication for moodlift and memory problems.
