Is any of this happening?
Be seen today
Seek prompt medical advice for increasing falls, new hallucinations, worsening swallowing, unexplained weight loss, medication side effects, or a clear decline in daily function.
These symptoms may have causes unrelated to Fahr disease, but they need urgent assessment.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop gradual changes in balance, movement, memory, mood, speech, or coordination.
You should also discuss an incidental finding of brain calcification, particularly if close relatives have similar scan findings or neurological symptoms.
Every sign above is quoted from the sofidex article on Fahr disease. If you are not sure, err upward — it is always reasonable to be checked.
