one patient that have intention tremor, without consider the expand of time, just determine if he could do it and we will give him 1 mark. Because his tremor make him couldn't take up or touch the pen precisely,need to give him chances, is it wouldn't influence this or others assessment like STREAM-CAT & PDA.

Intention (Cerebellar) Tremor: This relatively slow, broad tremor occurs at the end of a purposeful movement, such as trying to press a button. Intention tremor may result from a damage to the cerebellum or its connections. Multiple sclerosis and stroke are common causes. Wilson's disease, alcoholism, and overuse of sedatives or anticonvulsants can cause the cerebellum to malfunction, resulting in intention tremor.
