Micrographia is an acquired disorder characterized by abnormally small, cramped handwriting. It is commonly associated with neurodegenerative disorders of the basal ganglia, such as in Parkinson's disease, but it has also been ascribed to subcortical focal lesions. O'Sullivan and Schmitz describe it as an abnormally small handwriting that is difficult to read, as seen in the accompanying photo. Micrographia is also seen in patients with Wilson's disease, obsessive-compulsive disorder, metamorphopsia, or isolated focal lesions of the midbrain or basal ganglia.
