Delirium caused by lesions/brain damage
Aug 31, 2005
How likely is that brain damage which is causing delusions can be reversed? If that part of the brain which responds to drugs has been damaged, is it possible it can be healed? Would it matter whether the lesions were viral/parasitic?
Response from Dr. Horwath
The degree of recovery depends entirely on the nature of the brain disease. Brain tumors, such as lymphoma, can cause permanent brain damage, especially if they become large enough. Similarly, some infections, like CNS toxoplasmosis, can also cause brain damage that cannot be reversed. Infections like Herpes encephalitis, PML and cryptococcal can also cause lasting effects.
There is no general answer that applies to all causes. In many cases, if toxplasmosis, meningitis or other infections are caught early and treated appropriately, the affected person can recover completely, even if they were quite ill, and had symptoms like delirium or hallucinations at the worst stage of the illness.
