Brief Answer: Could be a viral infection sequelae Detailed Answer: Hi, Thank you for posting your query. I appreciate your detailed history, examination and investigations, and I must admit you have done a better job than the best residents in Neurology/Internal Medicine. From my side, you get a FIVE STAR for this presentation. Now, coming back to your problem, the main issues are lack of taste (subserved by facial nerve-chorda tympani branch) and change in emotions (subserved by hypothalamus/limbic system of brain) and lack of appetite/decreased sexual drive (controlled by hypothalamus). The most common cause for this is a systemic viral infection, which also affects brain and cranial nerves, and this can explain most of your symptoms. Generally, the symptoms would improve on own in a few weeks. Further investigations that could help in excluding other cases (such as ischemia-lack of blood supply to brain; considered in view of sudden onset of symptoms) and also to assess the severity would be MRI of brain, along with angiogram. There is no need to worry at present, as your symptoms do not suggest any serious brain disease. I hope my reply has helped you. I would be pleased to answer, if you have any follow up queries or if you require any further information. Best wishes, Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology) XXXXXXX Consultant Neurologist Apollo Hospitals, Hyderabad, For DIRECT QUERY to me: My blog:
