Siderosis and Subarachnoid Hemorrhage-Reply. Abstract In Reply.— Dr Braun's letter raises an interesting aspect of our case presentation that we did not address.Our patient is now seven years postonset of her neurologic difficulty and, to date, has not demonstrated dementia or deafness. She does not seem to fit the clinical picture described for superficial siderosis. Indeed, her only persistent sign of intracranial dysfunction has been nystagmus.
