<s>[INST] I am a fifty one year old female and had a kidney transplant in December. I have bouts of waking up and not remembering where I work or recent events. If I go back to sleep then usually I remember everything. I also have bouts of an aura and do not remember the past hour or so. It coems back but am in a fog until then. Usually this last five to ten minutes. [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Short term memory loss can be due to anxiety, depression, stress, emotional problems or mild cognitive impairment. Try to stay relaxed, take plenty of sleep, go for morning walks & take nutritious food along with the medications prescribed. Visit ER, get EEG done. You may take the help of a neurologist & psychiatrist if required. Short term memory loss is an indication of developing dementia/Alzheimer's disease. Hope I have answered your query. Let me know if I can assist you further. </s>
