Can adrenal insufficiency cause memory and cognitive problems?

yes: These symptoms can occur with adrenal insufficiency. The diagnosis is made through lab testings, not through symptoms alone. See your doc for testings.

POSSIBLY: First, need to determine if you really have addison's disease, or a primary pituitary issue, or other endocrine problems. Medication reactions might be the core issue. This needs to be sorted out, and other causes of your symptoms could include vitamin deficiency and hypothyroidism. Get all of this fully diagnosed.

Yes, in stress.: Adrenal insufficiency can cause memory loss, especially in stressful situations, as well as confusion, absentmindedness. There is poor resistance to stress, great difficulty to functioning well in stressful situations, or even to react to them, becoming paralyzed. Stress is experienced as being unfair, too much.
