Hi, my father is 79years old. He has been having episodes of severe lung infection since 2013. In addition to this, he has been having episodes of temporary memory loss, slurred speech, no concept of day or night, loss of motor skills, does not recognize what medicines he is taking, even though he is MD in pathology. His CT scan report states Paraventricular ischaemic changes, cortical atrophy, small infarcts in both MCA territories. Can he take some preventive medicine for his condition? Does his condition lead to Alzeimers? Thank you for taking the time to answer my question
