What medical problems cause memory disorders? And how do they do that?
Many medical disorders can cause memory disorders. Any condition or treatment that compromises brain function generally can cause memory loss as part of the clinical syndrome. Examples include vitamin B12 or folate deficiency, syphilis affecting the brain, thyroid disease, and the use of medications like narcotics given for pain, benzodiazepines (e.g., Valium), and steroids.
