<s>[INST] The neurologist says that having looked at my husband s MRI it is possible that he has a build up of fluid in the ventricle. He has had chemotherapy for lymphoma in the central nervous system and these new symptoms which replicate a TIA are worrying to say the least. He is now losing speech and ability to process for up to an hour roughly every 10 days. The neouologist seems laid back but I am at my wits end as I can see my husband s personality changing and we are both losing confidence. He doesn t have another hospital appointment until May 15th which is for an EEG. We still await a cognitive assessment and then the neurologist will view the results and we should see her in 3 months! Help please. What do you suggest we do? [/INST] Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion your husband is having mostly HY Chat Doctor.  It is narrowing of ventricles in brain. Ventricles are CSF (cerebrospinal fluid) transmitting system. So any narrowing in it can cause fluid accumulation. This fluid accumulation cause raised ICT (intracranial tension) and this can further cause compression on vital brain areas. This is the reason for personality changes and other neurological symptoms. Honestly speaking, lymphoma with neurological complications carry worse prognosis. You can ask for VP (ventricle peritoneal) shunt to divert the excess fluid and thus reducing ICT. So discuss all these in depth with your neurologist. </s>
