3. Dyskinesia: Dyskinesia refers to a category of movement disorders that are characterized by involuntary muscle movements ,  including movements similar to tics or  chorea and diminished voluntary movements. Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities.

14. Dysgraphia: A specific learning disability that affects a person’s handwriting ability and fine motor skills . Problems may include illegible handwriting, inconsistent spacing, poor spatial planning on paper, poor spelling, and difficulty composing writing as well as thinking and writing at the same time.
