This is a report about one patient, not a new treatment.
The short version
A man taking steroid medicine for cancer in his brain lining had severe mental symptoms.
What was studied. Doctors wrote up the case of one 66-year-old man. He had lung cancer that spread to the lining of his brain and spinal cord. He had taken steroid medicine for more than 9 months with no problems.
What they found. He got three more short rounds of steroid medicine. His mental symptoms got worse with each round. He went from being very agitated, to having thoughts of hurting others, to believing people were out to get him and refusing all treatment. The symptoms went away after the steroid medicine stopped and he got care in a mental health hospital.
What this means, and what it doesn't
What it could mean: Steroid medicine helps bring down swelling, but it can also affect the mind. Taking it for a long time with no trouble does not mean you are safe later. Tell your care team right away about big changes in mood or thinking.
What it doesn't mean: This is one person's story, not a study. It does not show how often this happens. It does not mean steroid medicine will do this to you. Most people take it without this problem. This is not a new treatment and not a cure. Do not stop your steroid medicine on your own. Talk to your doctor first.
