Hello, Thank you for your query. I do understand that it must be a hard period to yourself. But i believe i would be interested to know the age of your husband and also some facts about any other condition he suffers from, like Diabetes/ Hypertension (high blood pressure)/ Asthma/ Alcohol use etc details. But, from whatever the brief history that has been provided, i believe your husband might be suffering from what we call as Acute Confusional State also called a s Delirium technically. It would have so many causes and it needs to be investigated thoroughly and once the cause is found out, it can be reversed by treating the cause. On several occasions , it would be difficult to find a proper cause in which case, many a times symptomatic management itself would set right the condition. So you may request your doctors whether your husband has been worked up to rule out any possible cause and if yes, then to take a repeat opinion from a Physician/ Neurologist and Psychiatrist and other concerned specialists if any. I hope this answers your query satisfactorily, in case you have any more doubts, i would be very glad to reply to the best possible. Thank you and wish your husband a faster recovery. Regards, Dr.Narendra.
