The common causes of lethargy in the elderly are cerebrovascular diseases or some metabolic diseases. The elderly may suffer from somnolence due to insufficient cerebral blood supply due to cerebral arteriosclerosis, or suffer from brain function impairment due to cerebral infarction, cerebral hemorrhage and other cerebrovascular diseases. Such patients can be diagnosed by transcranial Doppler, head CT or head MRI. The elderly may suffer from body fluid loss, electrolyte disorder, and drowsiness when they are low in sodium and potassium due to poor meals or nausea, vomiting, diarrhea and other reasons. Most of these patients have poor diet, vomiting, diarrhea and other symptoms, and should be actively treated symptomatically. You can go to the hospital to test the electrolyte. If there is electrolyte disorder, it should be corrected in time. After the improvement of general diet and the correction of electrolyte disorder, the symptom of sleepiness will gradually be relieved.
