It may be a early sign of WERNICKE ENCEPHALOPATHY
. classical symptopms are-
1.confusion, and impairment of short-term memory
2. visual disturbances and
(abnormal movement of eye resulting difficulty in reading)
As you have all the three problems I suspect this. Though alcoholics are more prone to develop this it may be due to any disease that cause THIAMIN( a vitamin) deficiency.
Thiamin is required in several part of brain so in deficiency those parts start to stop functioning normally which produce the symptoms.
Thiamin supplement from outside is the main stay of treatment.
Go to a neurologist
as early as possible because if left untreated this may be turned into KORSAKOFF PSYCHOSIS
.(where those parts damage permanently). Best of luck.
