Micrographia (handwriting)

Micrographia, an acquired disorder, features 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 photo to the right. Micrographia is also seen in patients with Wilson's disease, Obsessive Compulsive Disorder, Metamorphopsia, or with isolated focal lesions of the midbrain or basal ganglia.
