Why Have I Had Periods Of Total Confusion That Is Recurrent?

I m 46 have had periods of total confusion. I tried to eat a padded hanger. I could find my bed. I tried to open a door by the wrong side. I couldn t figure out how to turn off a faucet. When my husband tried to tell me I wasn t making any sense, I argued with him. Could this be caused by my H&H has been a few points above the maximum normal for 3 years. I have been referred to Medical Oncology.
