<s>[INST] My husband 59 has been having intermittent symptoms when tired. He has slurred speech, (marbles in mouth), has some difficulty saying what he means and has short term memory loss. This has occurred 2x in the past month. I think he should see a physical and he things he is just tired. [/INST] Hello! Thank you for the question on Chat Doctor! I understand your concern. It is true that these symptoms can be caused when the patient is tired, and he can't concentrate. But I would try to exclude first other causes of these symptoms. Slurred speech can be caused by transient ischemic attacks or seizures. At his age he is at risk for these disorders. I would recommend a full blood work to rule out anemia or dyslipidemia, a neurological examination and an EEG for the seizure suspicion. A brain CT scan may be needed. Hope to have been helpful. Best wishes,  </s>
